A Little Background
Room air conditioners can be classified into various types. For example, the most common type is the window type air conditioner, if you just need to cool one room. If you want to cool many rooms then you can go for a central or ductless air conditioner. If you want a transferrable or mobile air conditioner then you can go for a portable AC unit instead.
If you maintain a home office or work as a freelancer at home, putting up an AC unit in your room improves your work mood and can also help you sleep better right after work. If you feel really stressed about something like a deadline or back job from a client then the cold air from the AC unit can actually have a soothing effect for your mood versus a very hot temperature indoors.
The benefits of having an air conditioning unit at home in your room can vary from physical to psychological effects. It not only improves the air quality in your home and lessens the chances of heatstroke, asthma and allergy attacks, it also helps people who are often stressed or tired to feel relaxed, and those who feel lazy to work to get them moving. Decision making is better in cool environments, which is why offices are usually fully air conditioned.
Because the air we breathe outside could be potentially polluted by allergens, pollen, irritants and the like, you might compromise on your health and safety. Indoors, the air can be inhabited by such sickness causing airborne elements so you may need something like a room air conditioner to help eliminate those. Most AC units come with air filters that can alleviate allergies, asthma and the like, aside from keeping you cool and comfortable all day.
A window type air conditioner can be found on different places, such as in apartments, regular homes, bedrooms, dorm rooms, offices, small grocery stores, small businesses and much more. They can be installed easily on small to medium sized spaces and are also commonly found on various public places.
The window type air conditioner is the most common type of air conditioner due to its wide availability, accessibility, ease of control and low upfront cost. The window type air conditioner can be found in most apartments and homes, especially on bedrooms. If you are a budget saver then you can go for a window type AC.
Having a clean air is a big responsibility, even if you do have an air conditioner. Cleaning up the air filter on a regular basis is highly important because it will help you reduce the pathogens and airborne particles that get stuck in the air filter for a long time. Ensuring that your air filter is clean all the time also ensures that your indoor air quality is good.
Air conditioners are great business investments to have because not only are they powerful enough to cool down an office or room, they can also cool areas as big as a grocery store or shopping mall. Most air conditioners are needed for nearly all business types due to the convenience it gives not just for the customer but also for the workforce.
Going for either a window type or a portable type air conditioner will still require you an outside exhaust, as a portable AC requires a hose or two while a window type AC is usually mounted with its back side outdoors. While both of them need to be stationed in one place in a room, portable ACs have the capability to be moved from the living room to the guest room to the bedroom and others.
For a room, you may be more satisfied with just a simple window type air conditioner. However, if you have a large room or multiple rooms at home to cool down, you might want to consider a centralized air conditioner as well, especially if you have the budget for it. Window units are more economical if you just need to cool down one room but if you like an even temperature in the whole house then centralized ACs are good.
How We Picked
If you want to have the best room air conditioner, you can look for the following factors:
Coverage area: from 200 to 800 square feet, you can get a room air conditioner that best suits your needs. It is important that you measure your area so that you can get the best for your needs. A room air conditioner that is too small can be overworked if you place it in a large area so make sure it is just right for your room or area. Oftentimes, BTU rating has something to do with its coverage area.
EER or SEER: the average SEER of most room air conditioners are at least 13 and above. EER or energy efficiency ratio and SEER or seasonal energy efficiency ratio determine if a room air conditioner is energy efficient and can save you a lot when it comes to your electricity bill. A higher EER or SEER for a room air conditioner means that it is sufficient for savings in your household on your AC unit.
BTU: the BTU rating of a room air conditioner can be from 5,000 BTUs and above, depending on how large the room can be. If you go for a larger room for your room air conditioner then you can go for a higher BTU such as 10,000 BTUs or more. The BTU rating of a room air conditioner determines how strong it is and how fast it is in removing hot air and converting it into cold air.
Energy Star certified: make sure that the room air conditioner is Energy Star certified so that you can have more savings in the long run. This ensures that your room air conditioner is not only safe to use but can also bring about better budgeting when it comes down to your electric bill.
Heating capability: most room air conditioners may also be reversed to have a heating capacity, especially if you have a ductless or centralized AC unit. While most room air conditioners are window type or portable ones, some may even have the option to be converted into a heater for the winter season or the rainy days.
Air filter: the air filter of this room air conditioner should be easy to clean, mostly washable. Some room air conditioners use HEPA filters to trap dirt, dust, debris, pollen and allergens that may cause hay fever and the like. Having a good air filter for your room air conditioner is important so that it won’t harm your family’s health. Being easy to clean means that you can service it any time.
Type of air conditioner: you have a wide choice of room air conditioner types: portable, window type, centralized or ductless. Window type ones or through the wall room air conditioners are great for most rooms as well as portable ones that can be moved from room to room. Centralized and ductless room air conditioners are a little expensive, but can cool all rooms in just one go and ductless can fine tune your rooms for zone cooling.
Inverter technology: those room air conditioners with the latest inverter technology run significantly more efficiently than older brands due to the variable speed feature. This type of technology is often found in newer room air conditioners – not only in ductless types but also maybe in window, portable and centralized types of AC units.
Dehumidifier: most room air conditioners will have a dehumidifier, which can be very helpful if you live in a really sticky or humid environment or if your summer is very humid. A dehumidifier for a room air conditioner helps to remove the sticky feeling as it cools down, so it is more effective than a regular fan in terms of cooling.

Other Frequently Asked Questions
Q: What are the different kinds of air conditioners out there?
A: There are many air conditioner types to choose from.
The most common one is the window type air conditioner, which is installed with a hole in the wall or in the window. You need ample space in your home before you go for the window type air conditioner.
The next one is the portable air conditioner, which can be great for those without enough space to drill a hole in the wall for a window type air conditioner. Portable ACs can be moved from one room to another but may require a hose to vent out.
Central air conditioners make use of two units: the indoor and the outdoor unit, to transfer the cooling to the rest of the house with the use of air ducts. These systems can be expensive.
Ductless or mini split air conditioners are great for zone cooling or heating and work like central ACs but do not use air ducts in installation.
Packaged air conditioners are an all-in-one unit that are mostly for commercial purposes.
Q: Why should I put air conditioning to my room or house?
A: The air conditioner can have physical as well as psychological benefits. It can improve the mood of a person when they are working, reading, using the computer or sleeping. You also get a better air quality indoors if you put air conditioning to each of the rooms. Air conditioning is great for those with asthma and allergies as well.
Most people who go for an air conditioner can also receive benefits of cooling down during the summer, especially for seniors or those who are prone to heatstroke. Many people can potentially die of heatstroke and if your house is not properly ventilated, it can lead to serious health problems. Air conditioning can be a life saver during the summer season.
Q: Which health problems can be cured with an air conditioner?
A: The air conditioner can help reduce allergens in the air, as well as many other airborne viruses and pathogens. In this case, air conditioners are widely accept as a good environment for those with asthma, sinus or other respiratory conditions. People who are prone to allergies (e.g. allergic rhinitis or hay fever) can help reduce the symptoms when they reside or work in an air conditioned environment more often.
Air conditioners can also be great for people who tend to have traumatic disorders, anxiety, depression and other mental health problems, as the cool air can help them calm down. Being all sweaty and hot can have a negative impact to a person’s mood, and this is why most hospitals and mental health facilities are fully air conditioned to help patients recover better.
Q: What makes the window air conditioner the most common AC unit for a room?
A: The window type air conditioner is usually the cheapest to buy from all AC units out there. A typical window type air conditioner can keep a single room cool and comfortable with a low cost, depending on the brand. They are also available on most common and popular brands out there.
Window type air conditioners are not just cheap but are also energy efficient, especially if they have a good EER of at least 10 or more. This signifies that they are not only eco-friendly but also good for your electric bill and your budget due to the lower initial cost compared to other AC unit systems. They are also good for lessening the load of a centralized AC system, if your home has one.
Q: What drawbacks should I watch for when using an air conditioner?
A: If you have an air conditioner then make sure you clean up the air filter regularly or as indicated by the user’s manual or the recommendation of the manufacturer. Bacteria, mold and the like can infest your air conditioner and harm the air quality of your indoor air instead of improving it.
Q: Aside from homes, which businesses require an air conditioner?
A: Nearly any business , especially shopping malls, grocery stores and even gymnasiums will require an air conditioner to help ventilate the area. Most of these business establishments will have closed areas so you need a good air conditioner to help cool down the whole business area or just a room, part or zone.
An air conditioning unit is typically needed for grocery stores and stock rooms because of the threat of perishable goods, such as fresh produce and other wet market goods. Spas and beauty centers should also have an air conditioner to make it comfortable for the customer, as well as shopping malls, to make it convenient for them when they shop.
Q: Which is better: a window type AC or a portable AC?
A: A window type AC depends on a hole in your window to work and can only be mounted once. On the other hand, portable ACs can be moved around even if they do require a hose to be vented outside for the excess water. Portable ACs are the best if you want to move the air conditioner from room to room. Window type ACs are the best if you just ideally want an AC in one room.
Q: Which is more economical: a window type air conditioner or a centralized air conditioner system?
A: Choosing between a window type versus a central type can be tough, especially if you have a medium to large sized house. Central types can be expensive in comparison to window types, but they can be more effective and efficient in cooling because they can cool down the whole house instead of just one room, in comparison to the window type air conditioner.
Q: How is a ductless AC different from a central AC?
A: The ductless and the central air conditioners have a difference that comes down to the duct work. Ductless systems do not require duct work but central air conditioners do. Also with a ductless system, you can select which rooms to cool down or heat up and which rooms stay the same. This is something that you cannot do on a central air conditioner system.
If you own a central air conditioner, it can be a hassle because you have to do some duct work or else it will not distribute air throughout the house. Central ACs also cool the whole house but not specific rooms. If you want specific zone cooling or room cooling then you should go for a ductless air conditioner instead of a centralized one.
Q: What is the best noise level of an air conditioner to help me sleep better?
A: An air conditioner with about 40 to 60 dB will be a good noise level to consider (in maximum) when pertaining to its motor noise. This will help you sleep better at night due to the low ambient noise.
Some air conditioners have a sleep mode, which lowers the temperature impact of the unit and also its motor noise. It is important for any AC unit to have a good noise level without disturbing your sleep and without compromising on your electric bill and its cooling ability overall.
Q: Are split system or ductless air conditioners okay to install in bedrooms?
A: Yes, ductless or split system air conditioners are totally applicable in bedrooms and in room air conditioning. While most of them can be big and an eyesore to your home’s aesthetics, there are smaller variants that look good and won’t interfere with your room’s design. In fact, zone cooling is one of the key benefits of ductless systems.
Q: What consequence can happen if I don’t select the right BTU of air conditioner for my room or area?
A: The BTU rating of an air conditioner is important to know about because it will dictate just how much cooling power it can give to your room. Having a BTU size that is too large can mean that it will cycle faster and skip the humidity, so the result is still a sticky feeling indoors. If the BTU rating is too small, it will not cool down your indoor area effectively.
Q: Is EER the same as SEER?
A: EER and SEER are both energy ratings that pertain to the energy efficiency of an air conditioner. However, SEER is for seasonal use and can be based on varying temperatures instead of just one with the EER. SEER is mostly seen in medium to large scale (usually commercial type) air conditioners that have a heating option or a heat pump along with it (e.g. centralized or ductless).
|Energy Rating||Minimum Requirement||Best For|
|EER||At least 10||Small scale ACs|
|SEER||At least 12||Medium to large ACs with heating option|
Q: Can air conditioners also become heaters?
A: Yes, a large number of AC units can have a reverse option for heating. This removes the hassle of having to buy an additional heater in the house during the winter. Having an air conditioner with a heater option can help you stay temperate all year round in your room or house.
Q: Why should I regularly check and clean my AC unit outside?
A: Most air conditioners will have an outside part (or at least half of it for window type and some portable types). The outside part should be cleaned and maintain to avoid the debris getting stuck and causing problems for the AC unit. It should be clear of falling debris from your tree or plants.
Q: Why should I change my air filter regularly on an air conditioner?
A: The regular changing of an air conditioner air filter is needed so that your AC unit runs smoothly all the time. It also won’t cause viruses and airborne germs to stay in the air because it is new and thoroughly clean. If it is washable, you can also clean it.
Q: Can a programmable thermostat give you more energy savings?
A: Yes, programmable thermostats that are installed on any air conditioner unit can help you save up on energy costs. Setting the temperature automatically when you leave the house or when you go to sleep at night will help to cut down on cooling (or heating) costs in the long run. It is also very helpful in case the weather outside is unstable and you need the right temperature for your room or house.
Q: Why should I keep my air conditioner fins in tip top shape?
A: Maintaining the air conditioner fins will do something good for your unit’s durability and longevity. The fins can be straightened out with a kitchen knife or a fin comb and this will help the ventilation fins to work as greatly as possible to cool down your room or area.
Q: Why don’t air conditioners use CFC anymore?
A: CFC or chlorofluorocarbons are harmful for the ozone layer and is a major cause of global warming, which is bad for the environment. More eco-friendly alternatives for refrigerants have been created today to help power up air conditioners without risking the environment at all.
Q: If my air conditioner is running but not cooling, what could be the problem?
A: The air filter might have been blocked by some formation of ice. You can easily fix this by turning on the fan mode of the air conditioner if you see upon your inspection that the air filter has been blocked with ice crystals on the coils.
