Among all the household appliances ever invented, the refrigerator is probably one of the things humans are most thankful for. Since keeping our very perishable food fresh, cold, and extending its shelf life has never been made this easy thanks to the existence of what most people consider as our kitchen’s best friend. However, just like living organisms; this cooling agent went through an evolutionary upgrade over the years before it has turned up to the version we’ve come to appreciate nowadays. So let’s take a walk down memory lane, and find out how refrigerators have changed from its roots to the most recent models of the decade.
Before we check out the various refrigerators through the years, it’s only proper that we first introduce the main man behind this ingenious invention. And it's none other than an acclaimed inventor who goes by the name of Jacob Perkins. Born and bred in the state of Massachusetts, Perkins' passion for tinkering and inventing various machinery was taken from his extreme curiosity with everything mechanical. and, it doesn't come much as a surprise that this mechanical engineer and physicist was given credit for various inventions throughout his life including machinery for nail cutting and heading, the bathometer, and many others. But his most notable creation was creating a refrigeration machine that is used for cooling via a vapour-compression mechanism. And this has become the backbone of our refrigerator appliances nowadays.
Even before machinery has ever existed, the very concept of using a low temperature to extend the shelf life of food was already practiced through more primitive yet effective means. If you're an outdoorsy kind of person or had the chance to go camping; you have probably noticed that some people would place wine or champagne bottles in a net and immerse it by the riverside. This cooling technique was made famous by older civilizations way back and has been practiced by generations even to this day. But the low-temperature concept made a revolutionary stride from ancient civilizations to this century, and here's how.
If you think that the earliest civilizations were already settled with just salting, sun drying, and smoking as a means to preserve and keep their perishables alive and edible then think again. The Egyptians were already clever enough to make use of the frigid night time temperature to cool down their food. They would store their food in large clay jars, you know like the ones you see archaeologists unearth in some Egyptians' tombs. And they would place it outside or on top of their roofs during night time.
Meanwhile, the Greeks and Romans were known for their ice houses which resemble that of a hobbit house from the Lord of the Rings film that has been dug from the side of a hill. The moist soil will then keep the inside of the structure cool like in caves. And then they would painstakingly collect large chunks of ice from nearby bodies of water that have solidified and store it in the ice house which acts as a natural icebox.
During the late 1700's, a professor from the University of Glasgow; namely, William Cullen first came up with the concept of vaporization as a means of artificially creating cold temperatures. The Scotsman then created a miniature skeletal refrigeration machine to prove his theory. Sadly, he never got around into making a larger version of it, but his concept became the base for all of the succeeding inventions leading to our current cooling appliance.
Around the year 1805, Oliver Evans used Cullen's concept but tweaked it by using vapor instead of liquid to produce the same cooling technique. The American inventor then proceeded in creating the first refrigeration machine. But sadly, it was still just a prototype, which is why the title of being named the Father of Refrigeration went to another American inventor named Jacob Parkins instead. And it happened a few decades later around 1834 when Parkins successfully came up with the very first workable refrigeration system through vapour-compression using ether. However, despite getting the patent for this machine, Parkins refrigerator failed to cater commercially.
This failure to meet the public's demand for a cooling device led to the creation of the first iceboxes. Unlike the ones we use nowadays that are made from Styrofoam, these were made of wood and had an inner lining of tin to help keep the block of ice-cold for more extended periods. But it turned into a flop just because people were not that keen on buying ice blocks all the time and continuously replacing the melted one. It's not precisely cost-efficient and practical that time, mostly when money was hard to come by. I mean, would you.
It wasn’t until when the early 1900's rolled in that commercialized refrigerators were finally produced. The Frigidaire Company, a startup business created by William Durant, started making refrigerators that have compressors below. And the well-known Kelvinator Company brand created its version that has a more "futuristic" touch by installing an automatic control system.
But it was the General Electronic Company and their Monitor-Top refrigerator in 1927 who successfully catered to the public's taste, and about a million units were sold. This started the stable market for what is to become one of the must-have kitchen appliances at present. Their version solely uses two chemicals as refrigerants; methyl formate or sulfur dioxide.
For the past years since refrigerators were developed, the main chemicals used for coolants were either sulfur dioxide, ammonia, or methyl formate. And it was during 1928 when Charles Kettering partnered together with Thomas Midgley, Jr. and created Freon. And it's the game-changing chemical that will soon kick out these three toxic compounds from the refrigeration appliance race. But it took a while before it was eventually used for the cooling kitchen appliance, with Frigidaire leading the pack around 1935 when it released their version that’s all Freon.
During the 1940's newer models have a more levelled up look, by replacing the safe-looking older models that have table-top legs with a more solid rectangular refrigerator that has rounded edges. By the 1950's, appliance repair for these kitchen mainstays has become even more complicated with the addition of various innovations such as automated defrosting and built-in ice makers. And it was also considered the decade of refrigerator mania as about 80 percent of American households own this appliance.
By the 1970's the rounded types have been replaced with a more sleek-looking box that has sharp edges. But it wasn't just the design that had a make-over since by this time people have become environmentally conscious after studies showed that Freon was killing our ozone layer and have geared to replacing the CFC compound. Furthermore, energy-saving refrigerators have also started popping out during this decade.
When the new century rolled in, technological advancement in various appliances and machinery has become unstoppable. And with the advent of the digital age, refrigerators have become more futuristic as companies began including computerized systems in the device. The internet has started penetrating the refrigerator industry, with some being capable of connecting with WiFi. Meanwhile, others can now be controlled using just your phones. And what’s more, the newer luxury versions are even voice-controlled.
There are just so many improvements we can give to our refrigerators to make life easier. And who knows what kind of upgrade companies are gearing toward these days for our appliances. There's only one thing we do know. With the additional innovative mechanisms, also means that it has become more of a challenge when conducting appliance repairs for them. Then again, we do love a good challenge.

If there is one thing that makes the kitchen one of the most attractive places to stay at, it would be due to the presence of none other than the refrigerator. This must-have home appliance is like a treasure trove that contains all of your prized food and drinks, keeping them cold, fresh, and edible for as long as it can. And besides your bed and television, the refrigerator has become one of your go-to things at home when you need some pick-me-up after a long stressful day.
Refrigerators are so valuable that even a slight mishap sends our moms to frenzy and panic. I remember my mom frantically dialing the repairman's number and begging him to come immediately and fix our fridge or else all of our food would go to waste. And refrigerator repairs don't come cheap, especially if the damage begs for a replacement part. However, as challenging as it may seem, you can still try to fix your refrigerator first before calling SOS. And here are some DIY refrigerator techniques you can do if you encounter one of these common fridge headaches.
A little bit of water does sometimes escape from your refrigerator from time to time; however, it is a different story if it's already creating puddles of water on the floor. Two problems often cause excessive water leakage; a broken water supply line or the drainage for your defroster has been blocked off.
A broken water supply line
Your refrigerator’s water supply can sometimes tear or have holes due to clogging in the line. And a simple fix is replacing the tube by a new line which you can easily buy in a hardware store near you. If by chance there is ice build-up clogging the line, let it thaw for an hour or two and you can turn your refrigerator on again. But if the damage is none of the above, then it's probably time to call for help and have your appliance repaired by an expert.
Blocked drainage defroster
Water leakage often happens when you're defrosting, but the water that should have been drained into the tank behind or below your refrigerator starts flowing in other directions. And it's all because your drainage hole is blocked by a build-up of small food debris or by ice. Remove the residue by either fishing it out with a wire or a coat hanger or by running hot soapy water mixture on it.
One of my favorite compartments in a refrigerator is the freezer, just because it’s that one place that keeps your frozen meat and desserts in excellent condition. However, it is a different story if the inside and even the outer rims start turning into Antarctica. You see, one of the most prevalent problems that require a refrigerator repair is excessive ice build-up in the freezer which takes forever to thaw out. And there are several reasons why this happens.
Broken door seal
Just like the main door of a refrigerator, the freezer's entry also has a sealant on its side to keep the extra cold temperature trapped inside the compartment. And due to wear and tear, this seal often breaks or becomes loose. You can try cleaning it out first and drying it thoroughly. But if that doesn't work, then it's high time to replace the gasket which you can either buy from a hardware store or order it from the company that made your appliance. Unscrew the old one, align the new gasket properly, and screw it back in place.
Freezer door left open.
There's a reason why the freezer has its door, and that's to keep the relative humidity of the compartment levelled. But sometimes, either due to laziness or us being in a rush; we often forget to close the freezer door properly. This will cause a sudden spike of humidity which will, in turn, signal the fridge to work double-time in lowering the temperature, causing the excessive formation of ice. Be sure to always close the door properly and make sure that it's sealed tight. If by chance the door is already loose, then you either replace it or tighten up the screws. If by chance these two are not the culprit, then it’s most likely that your defrost timer or even your temperature sensor. And that means it needs its immediate replacement which only a maintenance specialist can do.
Oh, how we love quiet purring machinery in an appliance because that shows that everything is running smoothly and all its components are in top shape. However, if you start hearing some rumbling and rattling noise whenever your refrigerator turns on, then that only means trouble. The not so pleasant noise is often due to loose parts such as the condenser fan, the compressor tubes, defrost timer, or the drain pan.
If it's just the condenser fan, then a little cleaning and dusting are all that it needs using a soft-bristled brush. Meanwhile, if it's the draining pan, then nudge your fridge and turn it around to expose the drain pan. Remove its contents, slide back in place, and screw it tight. But if the trouble lies with either the compressor or defrost timer, then the only way to repair it to replace these parts.
Although your refrigerator is always plugged in, this cooling appliance, like the air-con, has a built-in control timer that turns it on and off from time to time to save electricity and minimize ice build-up. That's because a continually running refrigerator can take quite a big chunk in your electricity expenses if not fixed as soon as possible. And this usually happens if you leave the door hanging open, allowing warm air to get inside. Furthermore, a fridge filled to the brim will always run more than usual to make sure that it cools down all of the food stored inside. But here are the most common component culprits of a continually running refrigerator:
Dirty condenser coils
The condenser can easily be exposed to dirt and debris such as dust and fur. It is usually located at the back of your refrigerator behind the grille. Once you've unscrewed the grille, carefully use a low-powered vacuum and such out all the dirt. Then use a soft brush and dust away from the remaining debris on it. Be sure to clean this up now and then to avoid this problem, or you can also hire a maintenance man who specializes in refrigerator repair and cleaning to do this for you.
Faulty door seal
Notice that white, grey or black rubber at the surrounding your refrigerator's door? That is the gasket that serves a sealant to keep the cold temperature in and the warm air out. As your fridge ages, it undergoes wear and tear, and the gasket is usually the first part that breaks or gets damaged over time. You can unscrew this and replace it with a brand new one. Just make sure to screw it tight when replacing to avoid loosening in the long run.
Fixing your appliance on your own may seem like a daunting and problematic task. Refrigerator designs nowadays are far more advanced with complex machinery and components. However, there are some refrigerator repairs which you can smoothly perform on your own with a little help online. Only, be sure to assess and locate the damaged or faulty parts first before going ahead with your DIY refrigerator repair. In the instance that you're way out of your game with your appliance's problem, then it's the time to call for professional help.

Aircons have become a home and commercial establishment appliance necessity over the years ever since it came to the spotlight. And it has drastically changed how we live, as it creates a more comfortable and stress relieving indoor environment that the older generation never got the chance to experience.
Just imagine working in an office or studying in a classroom with just an electric fan working overtime to stave off the heat. Too stressful, annoying, uncomfortable, and unconducive for learning and working right? I mean, how can you even concentrate on what you're doing and be productive if beads of sweat are dripping all over your body. This is why people nowadays are more than willing to spend thousands of cash on electric bills so that they can enjoy the calm environment that air conditioning appliances create.
And if you are someone who’s on the hunt for the perfect aircon appliance, then you better have a good grasp of the various types of AC units available in the market today. Choosing starts with knowing, after all, so let's dive in, shall we?
Also known as window rattlers, this AC unit is one of the most commonly used types for the past decade. And you can still probably see some homes or establishments that have these sticking out of their windows. Window AC units were so crazed back then that almost all of the apartments, hotels, condo units, and offices that were built during its heyday had this installed.
It's relatively small, box-shaped, and can easily fit on your window; hence the name. Although it’s capable of creating a cool breeze, these units can make quite a racket with its noisy rotors. But surprisingly, a lot of people still opt for this unit rather than the newer split type models as its cheaper to replace the latter than maintain the other.
When you think that the invention of air conditioners was already impressive, wait till you find out that some created units that can even be portable. Perfect if you don't want a cooling appliance that's fixed in a single room, portable AC units can easily be moved from one place to another. There are several different variations, such as split mobile AC units, water-filled mobile units, and those that have wheels on.
This freestanding unit has all its necessary parts typically and only needs an outlet for the cord to power up. However, there are portable ACs that come in a pair of refrigerant pipes and electrical lines which must be connected to function. And although you can practically be lugged and bring them everywhere, this type of air conditioner can be quite noisy and are only capable of cooling small spaces.
Known to be one of the public's favorite, wall-mounted AC units have various sizes and capacities that you can choose from depending on your room size and your needs. The most common of which is the box types and the rectangular ones. And as the names suggest, these AC units are retrofitted into the walls of your homes, establishments and offices.
Most house and building builders would need the final decision of the type of air conditioner appliance to be used in the infrastructure they are building. That's because using wall-mounted ACs means creating a space in the wall beforehand, like a crevice where the size must fit the unit like a glove. Cooling capacity wise, this type can pretty much keep large or small spaces cold throughout. However, they must be installed by AC engineers alone for safety purposes. So that means say goodbye to DIY installation if you choose this unit.
You have probably seen these a couple of times already, as floor-mounted AC units, especially the column types, are typically used in fast-food restaurants, libraries, and lecture halls. Column floor mounted units are towering in height and are categorized as high-capacity ACs. This means they are capable of cooling large spaces like restaurants and cafes on its, thanks to its strong airflow, which are often dangerous to people if at max.
Meanwhile, the smaller cabinet floor mounted units often resemble that of a storage heater which is box type but slimmer. Due to their relatively smaller size, these units are capable of generating about only a third of the column BTU capacity. However, both floors mounted types require a lot of cabling and pipeline work as they don't come with quick connection pipes, unlike other types of ACs.
Considered as the future of energy-saving air conditioner evolution, ductless mini-split units are the top of the line when it comes to efficiency. It comes in a set, which includes a central outdoor unit where the compressor and condenser are located and one or several indoor units. These are then connected with tubings that run throughout your home where the smaller units are placed. This way, you can quickly provide a relaxed environment without the need of buying several separate AC units.
The more advanced versions nowadays are equipped with WiFi connectivity wherein you can use your phone to control the entire system. The only downside is it is incapable of cooling larger homes or offices due to its somewhat limited capacity. Plus you’ll have several pipes and lines visible which can be a visual buster and may even sometimes look a bit messy.
The complete opposite of the ductless mini-split type, the central air conditioner units use ducts installed in various areas or rooms throughout the building or home. These ducts serve as cold air outlets which are then connected to a central unit located outdoors where the compressor and condenser are located.
But what separates this from the other units is its immense capacity to cool big separate spaces all at the same time. Hence, it is more commonly used in factories and food processing plants. It lowers the relative humidity and temperature at a much faster rate compared to others. However, the big downside is its ability to eat away your money as it requires vast amounts of electricity to function. Plus, maintenance can be quite a headache, especially if one of the ducts is busted.
Choosing the perfect cooling appliance may be quite a challenge, but it's best to have a thorough research about each unit first. And it will be a lot easier if you already have a good picture of your house or establishment's layout, the space of each room, as well as the number of people who will be staying in that space. Furthermore, air conditioning appliances can be quite expensive not only the unit itself but also the electricity bill it gives you at the end of the month. So you better take budget into account as well as air conditioner repair maintenance. But after you have gone through all that, then you are all set in choosing and purchasing your number best friend during the summer.

One of the most revolutionary kitchen appliances ever invented is the oven. Just imagine a world without it, no birthday cakes, breakfast bread toast or bagels, or even our all-time favorite pizzas. A week doesn’t go by with us not stuffing our mouths with some form of food freshly baked from the fiery heat of the oven, which is why it's not much of an exaggeration if I say that our lives would have probably been incomplete without this culinary-wonder appliance.
Now, although historians believe that some form of the oven was already being used during the first civilizations, it wasn't until the 1400's when the very first oven ever recorded was built. And it's not much of a surprise that it was in France, one of the culinary hubs in the world, where this brick and tile oven was created.
However, our modern stainless steel ovens nowadays is a far cry from its older predecessors. And there have already been several various versions of this appliance created throughout the years. Let’s check out the most common types of ovens and find out which one best fits your needs.
One of the most popular types which you can find in most middle-class homes is the freestanding oven. As an appliance which caters to small houses with limited space, freestanding cookers became a favorite thanks to its 2-in-1 feature. You see, this kitchen appliance not only has a medium to the large-sized oven but it also comes along with a stovetop or cooktop above the stove itself. This space-saving wonder allows you to cook multiple meals at the same time in one single appliance without the hassle of moving to and fro on a separate stove.
What's more, the cooktops come in several varieties, including electric, induction, and gas types. Another well-loved feature of freestanding ovens is how you can quickly move it around your kitchen if you feel like rearranging the room, as most models come with a set of rollers which you can lock in place. The only downside of this oven type is its height since you need to bend your knee and back whenever you are baking something. But then again some do consider this a fun stretching exercise, but not for the oldies though.
When you hear the words toaster oven, I'm pretty the first thing that comes to minds is bread. Well, luckily you'd be half right as this type was initially created for toasting bread. However, the innovative design not only allows toasting but also baking only on a more small-scale version than the larger heavy-duty ovens in the market. This small, compact, and easy to carry cooking appliance boasts one to two-level rack levels with a manual pop-up door. What's more, unlike the freestanding oven, this one solely depends on electricity to work.
Although the older models have minimal cooking and baking capabilities; the newer and more advance versions have now additional features with the most notable being the air fryer toaster ovens. These relatively larger toaster ovens have taken the world by storm these past few years thanks to its several advantages. Among which include its portable size, multiple frying, baking, heating, and roasting features, and its sleek design. Sadly, it is still no match to the original ovens as size comes with limitations.
A more turn of the century appliance design, the convection ovens is what most people consider a better conventional range upgrade. The kitchen appliance itself still resembles the original ovens except for its additional heating feature that its predecessor lacks. You see, as the name itself suggests, this type of range heavily relies on the process of convection wherein the hot air circulation system penetrates deep into your food for faster cooking.
However, it’s not just the reduced cooking time that makes convection ovens popular. Thanks to its fan system that allows even circulation of hot air; a more even cooking is achieved plus it produces crispier roasted meat while still retaining a moist and juicy inside. This tabletop appliance is also an electrical type of oven, and the acclaimed air fryer is one perfect example of it.
Another electric oven, microwave ovens or known as microwaves are probably one of the most well-known in the market. It’s known as a college student and starting young professionals’ best friend. All thanks to its multiple functions focused on heating and reheating meals which any solo-flying adult living in a dormitory or apartment would consider as food saviour; microwaves began selling like hotcakes when it was first commercialized. And it has also opened new doors in the food industry, where food processing companies started catering packaging materials that are microwave-ready.
Although considered as an oven, microwaves use electromagnetic waves to create thermal energy as its heating method as compared to the conventional fiery oven that we grew up with. The advantage of which is a faster and even heating speed that most ovens fail to achieve. Sadly, since it only produces a narrow range of temperature, microwaves are often regarded as not suitable for more elaborate cooking and are simply fit for heating soups, cup noodles, and microwavable meal sets.
Commonly used in commercial food production establishments such as bakeries, cake and pastry shops, pizza parlours, and various restaurants; the built-in ovens or wall ovens are one of the more original models that are still being used today. Of course, these kitchen appliances have already gone through several upgrades as compared to its first-generation models since then. But they are still considered as the most reliable, spacious, and perfect baking or roasting machine among the rest.
They are so named because unlike the freestanding or tabletop ovens; these are fitted explicitly into the wall in the kitchen space. Usually, people who opt for such ranges include it's placement on the design of their homes or establishments as these will fix and are not movable or portable. Built-in ovens are more extensive and are often regarded as the better space saver thanks to its seamless fitting in your walls or cavities. And these usually are gas-powered, but the newer designs are partly electrically powered and even have touch screen buttons rather than the usual circular knobs.
With over a dozen different kinds of ovens available in the appliance market nowadays, choosing the perfect one has become more of a dilemma. However, it may not seem easy at looks; buying an oven can be a fun and enjoyable task. Consider the why and where first; why you're buying one and where are you going to use it. Once you've considered its purpose, the next you should take into account is budget and space. Is your money enough or do you have a larger or smaller space in your kitchen.
And when you finally have a better grasp of your household and financial situation, choosing which model best fits in your circumstance comes next. You should also consider its features, electric or gas, double-door or single door, conventional or convection, size, cooking and baking capabilities, etc. You must take everything into account so that you'll never regret your decision once you've purchased an oven. After all, kitchen appliances like ovens are as crucial as our gadgets; they are a long-term investment that we will never get tired of.

With the constant innovation thanks to technological advancements and out of this world ideas, our food's shelf-life extending appliance has come a long way from its forefather versions. And nowadays, there are so many different kinds to choose from in the market with varying sizes, shapes, colors, usage, and features. The sheer number of refrigerators available in the appliance store is so many that buyers, especially the first-timers, often find it an overwhelming task to choose which is the best for their needs.
However, besides focusing simply on your purchasing capability, a smart buyer should have a good idea of what he/she wants in a refrigerator and what it can give in return. And since some people buy an appliance like the fridge is akin to entering into a long-term commitment, we've compiled the six basic types of refrigerators to give you a peek into the bigger picture on how each appliance differs from the other.
A double door style, which honestly resembles that of those old school wardrobe cabinets way back, the side-by-side refrigerator is more of an easy access kind of fridge. Compared to the usual horizontal splitting of compartments, this refrigerator is vertically split, wherein one side gives you the freezer while on the other is your traditional fridge compartment. Although both chambers have unequal width, some provide an equal amount of space for both sides.
But since this is a more slender sized refrigerator appliance, expect that you would not be able to fit larger or wider items, especially on the traditional compartment side. Its narrower space also limits the amount of fresh or pre-cooked food you can store inside. Plus, it's one of the more high-end expensive types of the fridge.
What separates the side-by-side refrigerator types from the rest is that it provides you a much larger freezer storage space. So if you're planning to stock a lot of frozen products such as processed meat and desserts, this is the best cooling appliance for you. It's also perfect for small spaced kitchens thanks to its slimmer doors.
If the side-by-side type and the bottom freezer refrigerator had a love child, then it’s got to be the French door refrigerator. The upper half is a double door, two fresh food compartments that are split vertically. Meanwhile, the bottom half is one big freezer that goes all the way to the base of the fridge. But there are also versions where you can get a double drawer freezer compartment below instead.
This innovative refrigerator appliance first came out during the 1990's but became popular nowadays after going through a series of touch-ups and upgraded features. Its sleek and aesthetically pleasing design is a perfect addition to any kitchen. Furthermore, unlike the side-by-side refrigerators, the French door types are spacious enough for your fresh goods and your frozen food to make a favorite for large households. Sadly, the major downside for these types of refrigerator appliances is its super expensive price tag and not easy freezer access for pregnant women and older people.
Considered the most popular in the market, the top freezer refrigerator is the cheapest and most common among all types of refrigerators out there. You can practically find it in most households worldwide, and it's the one that I grew up loving. This classic favorite also carries that original two-compartment design that is horizontally divided with the freezer on the top half and the fresh food space on the bottom. It also comes with a slide-in compartment within the main body dedicated to fresh vegetables and fruits.
Typically the go-to refrigerator, especially by college students, single young professionals, newlyweds, and large families, thanks to its budget-friendly price and spacious compartments. Furthermore, its simple yet stylish design is the perfect fit for any kitchen. However, the big letdown is that it is quite bulky and eats a large portion of your kitchen space so that you can fully swing that huge door open.
The complete opposite of the top freezers, the bottom freezer refrigerators, came out later in the market but also has become a popular option among consumers nowadays. As the name suggests, it typically has the same design as the classic ones except that the freezer compartment is located at the bottom part of the refrigerator appliance. But what separates it from the top freezers is the freezer feature, which opens either via a door or slides out just like a dish rack drawer.
Price-wise, it's also one of the most affordable ones, often coming second to the top freezer refrigerators. The fresh food compartment is also a lot easier to access than the usual bending down movement when reaching for your food. However, this feature is a bit of a con, especially for kids, as it is often too high for them to reach. But then again, who cares if you can easily grab an ice cream or a pop from the bottom freezer, right?
Also known as the classic refrigerator, the compact refrigerators resemble the first-generation box-type versions having only one single door and compartment. However, unlike the older ones, some newer versions have built-in freezers already installed inside. This additional feature allows a compact refrigerator to work in two ways, either for fresh food or frozen foods.
Also, a cheaper type, mostly because of its smaller size, compact refrigerators, is commonly found in hotels or studio-type apartments. These mini refrigerators have become a popular option, especially for small-spaced accommodations and even offices, thanks to their space-saving size. Sadly, the limitations in space only allow a few items for storage.
Last on our list is one of the newer and quite innovative refrigerator designs in the market. The built-in refrigerators are considered the perfect space-saving fridge and often resemble a standard kitchen drawer. It comes in varying sizes and features depending on what you want decoratively, aesthetically, and functionally for your kitchen. But since they are custom-made and require a more sophisticated installment process, built-in refrigerators are very expensive and can put a hole in your pocket. That and the fact that it is a lot harder to maintain or fix if ever problems arise often make this type a not so good choice. Despite that, many kitchen restaurants and even high-class mansions opt for this nowadays as they consider it a better investment, especially if they are designing their kitchen from scratch.
Now that we have shown you the basic pros and cons and features of these major types of refrigerator, it is up to your buyers to think about which one fits best for your needs. And although no matter which one you choose, it will put a serious dent in your pocket. But as well say, refrigerators are that one appliance that you'll never regret investing in in the long run. After all, it not only keeps your food cold and fresh, but it also effectively extends its shelf-life for as long as it can.

Whether you are lounging at home or working in the office, there is nothing like the comfort of a cool environment that only air conditioning systems bring. Growing up, I've always thought that AC appliances are an unnecessary luxury because there's still electric fans that are way cheaper. But I only came to appreciate its benefits during my college years, when almost all of our rooms and lecture halls have air conditioners. I mean working, studying or resting in a room or establishment with a cooling system is way more relaxing both for the body and mind.
And this is why nowadays, more and more households and commercial establishments invest in installing an AC appliance. However, just like any state-of-the-art appliance, air conditioners are also prone to technical problems, especially with the normal wear and tear process as time goes by. And since our AC systems are such a large investment, having a good idea of what kind of malfunctioning problems is must help protect that investment. So we have compiled eight of the most common problems air conditioner appliances often run to during its "lifespan".
The magic liquid that produces that cold air from your ACs is known as the refrigerant. And one of the most common problems that this appliance often experiences is the sudden billowing of warmer air rather than a cooler one due to a leaking refrigerant. Leaks can be easily fixed but what's problematic is locating which tubes have holes or tears. Although you can inspect it on your own, having an expert repairman check it out is more reliable and comforting. However, once you've patched up or replaced the tubes and added the lost refrigerant, your air conditioner will once again start producing cool air.
Since air conditioners are a form of a ventilation system, it also contains an air filtration component. The air around us constantly contains dust and small dirt particles. And no matter how much of a clean freak you are at home, your ACs filters will eventually start packing up all of this dirt overtime. Sadly, clogged up air filters restrict airflow, which is why you'd notice that as time passes by, it takes a much longer time before your room completely cools.
A monthly cleaning maintenance is must especially for this component, but if you have furry pets around then cleaning it at least every two weeks to remove all the hair should do. And replacing your air filters annually is usually what the manufacturer would recommend keeping your air conditioners in top shape.
Basically, the compressor is the component responsible for driving the hot air that has been sucked in by the AC and blows it towards the condenser coil. And this, in turn, transforms that hot, humid air into a cold breeze. If your air conditioning system is not properly creating that cool environment, it probably means that your compressor is busted. Furthermore, a malfunctioning compressor can also be due to an insufficient amount of refrigerant left in your AC, a faulty wire, or a dead capacitor.
There are two separate fan components in your air conditioner. One is responsible for blowing air in, and the other is for pushing hot air out towards the condenser. And suppose one or both of these fans stop working or start malfunctioning. In that case, airflow will be disrupted, which can lead to several other problems such as the inability to produce cool air and a more problematic compressor crash.
Stuck propellers often cause faulty fans in air conditioning appliances due to dirt and hair build-up, the belts are already at its breaking point, or due to a motor failure which powers the fans in the first place. Usually, a simple thorough clean up can already address the problem, unless of course the fan itself or the motor is already broken which means parts replacement.
All air conditioning systems have what you call a thermostat. This is the device which controls your cooling appliance, and it is considered as the brains of the AC. Thermostats are responsible for setting up the temperature levels, and when the appliance should turn on or off. And whether your AC still has the old dial ones or the new smart programmable versions that can be connected with your smartphone, all thermostats must be calibrated before using an air conditioner.
Calibration is necessary to get just the right temperature for your room or establishment and must be adjusted depending on the outside environmental temperature. This not only keeps you from turning into a human popsicle, but it also helps save energy keeping your electric bills from unnecessarily shooting up sky-high. Improper calibrations especially for the tricky manual versions often happen and can either give you fluctuating warmer or colder temperatures. Furthermore, placing them under direct sunlight can also cause it to go haywire, so be sure to position them in a more shaded area.
Being a cooling appliance, it's not surprising if air conditioners start having ice formation and build-up inside. And the most common part that often becomes frozen is ironically the evaporator coils. Mind you; evaporator coils are those intestine looking tubes in your ACs which contain the holy refrigerant liquid and are responsible for sucking in all the heat from the warm air. Just think of it as the steel sponge and the lungs of the air conditioner.
Now, if the airflow suddenly goes crazy, it's the evaporator coils which pay the price and turn into a frozen icicle. And if they become iced, expect a heater rather than a cooler from your air conditioners. Furthermore, this component is often prone to corrosion and rusting, so a periodical check-up is a must if you want to continue getting cold air from your AC systems.
In retrospect to the evaporator coils, condenser coils are responsible for blowing and expelling out all of the heat from the warm air that was sucked up by the evaporator coils. And since condenser coils of various air conditioning systems are situated outdoors, they are subjected to all the dirt, dust, and grime build-up. Furthermore, they are also left out in the open being constantly bombarded by various degrading factors which is why condenser coils are often needed to be replaced over time a lot sooner than other AC parts.
The problem is when all the dirt and dust start piling up and eventually blocking off the condenser coils, this will then lead to heat getting trapped inside your AC system. Once it gets hotter, air conditioners tend to work double-time to off-set the heat build-up. This causes too much strain on other components which leads to an eventual malfunction of the entire system. Hence, cleaning and maintenance, especially for parts exposed outdoors, is a must to prevent an overall air conditioning failure.
Although air conditioners tend to give off this soft humming sound when it turns on or starts running again; hearing a series of clanging or banging noises is a definite cause for alarm. However, these weird noises may be caused by not one, but several reasons and pinpointing the exact culprit can be quite a headache. From broken motors, to lose belts and fan blades; the possibilities can be quite a long list. Checking and identifying the cause can be done by the appliance owner. Still, it's better if a professional air conditioner repairman does it rather than you to be sure that you get the right diagnosis.
Brands may tell you that their appliances are built to last; however, let's be honest and admit that nothing lasts forever, not even your air conditioning systems. Everything has a breaking point sometime, especially if you're not taking care of them properly. And just like any home appliance or machinery, air conditioners are also prone to damage and decay as you constantly use them. But providing them with an annual or twice a year maintenance check and addressing whatever issue they encounter immediately helps extend your home appliances' lifespan.
