A Little Background

A small air conditioner is usually either a portable or a window type or even a through the wall type. Most small air conditioners have very low BTU ratings and thus, they are mostly meant for smaller areas such as bedrooms, apartments, condo units and dorm rooms. A small air conditioner will usually be capable of filling a room with cool air up to 400 square feet or less.
While a central AC and a ductless AC is something that is more meant for large scale use, a small air conditioner can just be a simple window type unit, wall unit or even a portable unit with wheels. There are, however, some specifically designed ductless ACs that are small enough to fit into small rooms. A good example of this small air conditioner would be an RV air conditioner.
Using an air conditioner, even just a small air conditioner, can be beneficial in the summer. Heatstroke is one of the major cause of deaths around the world. However, heatstroke can be prevented with proper ventilation and cooling such as with the use of an air conditioner.
If you are used to cold climates such as in Europe and North America, you may feel really weak in the summer, especially for old folks who are susceptible to heatstroke and illnesses caused by sudden temperature change.
Calculating the right BTU rating for your air conditioner is important so that it does not become an overkill for your room or area. You can measure the area first and then multiply that number by 25. For example, a 20 x 20 room will equate to 400 square feet in size, which, when multiplied by 25, will result to 10,000 BTUs, which is a pretty powerful air conditioner BTU rating to consider for mediums sized rooms.
Cleaning the air filter is one of the things that most households tend to forget. You should clean the air filter regularly on your AC unit or else it can lead to operational failure for your AC unit at home or in the office. There can be a check filter light or you clean it as scheduled depending on what your user’s manual says.
Traditional fans are good at cooling but air conditioner units are better if you have really hot summers. This is because traditional fans only blow air but do not take away the humidity in the air, thus not very good at cooling overall. Air conditioner units are the best to have if you live near the beach or have highly humid weather or climate.
One of the common AC units in most households is the split AC. The split type air conditioner is usually made for medium to large homes so small spaces may not be that ideal for a split type AC. However, there are newer ductless air conditioners today with inverter technology that may fit into smaller spaces such as apartments. This lets you cool down a room and then keep one room in constant temperature to save up on energy costs.
The lifespan of your air conditioner can be prolonged if you subject it to regular checkups from your HVAC personnel who is licensed. They can point out which parts of your air conditioner unit need to be given protection. Having a checkup is better than repairing because repairs can cost more than a regular maintenance checkup. This is why you should consider getting an HVAC professional to check your AC unit regularly.
Whichever type of AC unit you install in your home, you should make sure that it is just the right thing for your budget and for your home space. Room air conditioners are applicable for small homes and small rooms, which can be either portable or window mounted. On the other hand, central and ductless AC units are the best for whole house cooling as well as medium to large areas.
When shopping for an air conditioner for a single room, you may chance upon either a window type air conditioner or a portable one. Portable AC units are more expensive because they have the convenience of mobility, which allows you to move the AC unit from room to room versus a single window type air conditioner unit that is only stationary in your room and can be rather hard to install and lift.
The R410A refrigerant replaces CFC and HCFC based refrigerants to make the air conditioner more eco-friendly in general. Being environmentally responsible for any appliance can help you save the environment and also be more considerate towards your economical awareness. R-22 and many other older refrigerants can get in the way of the environment so you should look for modern ACs that use eco-friendly products and components to cool down the air.
The fact that portable ACs have a set of wheels or casters make them very mobile and convenient to use from room to room. In fact, they are the best for homes with very limited space versus a window type air conditioner, which will require you to sacrifice part of your window for the AC unit. This can be troublesome for those in apartments or small homes, as well as condo units and dorms.
Having a programmable air conditioner with a thermostat means that you can save more on your electric bill because you can automatically control the cooling (and even heating for some models) scheme of your house, whether it’s a bedroom, your apartment, condo unit, dorm or some other small to medium sized space. It can save you money in the long run so having a thermostat is a good investment.
Having a thermostat is good, but if you do not know how to operate it properly, you can be in for some serious trouble, such as the AC unit not working properly. You should not set it too low so that the AC unit will not overwork itself or run too fast that it won’t cool your room or area down sufficiently.

Other Frequently Asked Questions

Q: Can air conditioners provide better health for your home or office?
A: Yes, air conditioners can have health benefits for people. An air conditioner can purify the air of dust, dirt, pet dander, allergens and bacteria, which can potentially keep colds and other viruses at bay. The air quality will improve at home if you have an air conditioner as well.
If you have allergies or hay fever, you can benefit from an air conditioner. This is because an AC unit has an air filter to keep the dust, pollen and allergens away. In addition to that, workforce can be improved if you keep an air conditioner in your office or home work area. This is because the cold air is better than hot, warm air that employees feel sticky and irritated in.
Moreover, having an air conditioner at home or in the office improves your mood because you can make decisions better with a cool temperature, whereas you will feel irritated and stressful if you often reside in a very hot and humid climate area. Overall, air conditioners are great for your health, whether physical or psychological.
Q: How do I know which BTU of air conditioner fits my area?
A: You should measure your area first before you go on and buy an air conditioner that fits your needs. For example, a room that measures 12 x 16 inches will have an area of 192 square feet. To get the optimum BTU rating for an air conditioner, you can multiply that number by 25 to get 4,800 BTUs, which is the ideal BTU rating for your AC.
Q: What is the importance of cleaning your air filter in your air conditioner?
A: The air filter is the most important thing to maintain for your air conditioner because the air filter can get dirty when it is not cleaned properly. You should know when to clean your air filter based on its schedule and the recommendation of the manufacturer or user’s manual.
Not cleaning your air filter can have bad effects to your health and indoor air quality because not only can it form ice crystals but it can also re-circulate the dust and allergens into your air. You should clean the air filter as instructed or when the check filter light (if any) goes on. A clean air filter ensures a healthier environment at home that helps you stay cool.
Q: Can air conditioner units perform better than traditional fans?
A: Yes, on highly humid weather , fans may not be as effective when it comes down to cooling your air in the summer. Because the summer weather can tend to be highly humid, it will leave a sticky feeling even if you turn the fan on to cool down. This is why an air conditioner is specifically devised to help remove humidity in the air to keep things less stickier.
Q: What are split air conditioners? Are they expensive?
A: Split air conditioners are air conditioners that can be selective in terms of cooling rooms in the house. They can be either ducted or ductless but most of them can be much more expensive than your regular window type air conditioner due to the upfront cost and the setup needed by an HVAC personnel.
Q: Can preventive maintenance for your AC unit help its lifespan?
A: Yes, preventive maintenance or a regular checkup for your air conditioner unit can really help to improve the lifespan of your AC unit. This is because the HVAC personnel will be able to pinpoint which parts of your AC unit are not working well and will give you pointers on how to fix it.
Moreover, AC units may look like they are okay but there can be potentially underlying causes of failure that you may fail to look at. This is why you need an AC specialist such as a licensed HVAC personnel to help you determine which parts may need to be fixed or serviced before you run into a bigger problem and spend more money on repairs.
Q: What types of AC units are available in the market?
A: There are many air conditioner types in the market for you to choose from.
Most medium to large homes can have a central AC unit or ductless AC unit with a heat pump to get them ready for the winter. These may require some setup and an HVAC professional but the result is good benefits for you during all seasons of the year without the worry of getting another heating unit.
Room air conditioners, which fall into either window types or portable types, are much more economic and are good for a starter AC unit. If you just want to have an AC unit but don’t want to spend a lot of money in buying one then you can start off with a room air conditioner. It is also by far the most common type of air conditioner in the market.
Q: In terms of cost, which is better: a portable AC unit or a window type AC unit?
A: The portable air conditioner is usually much more expensive than a window type air conditioner simply because it is a lot more convenient and portable. It is equipped with specialized parts that are not in the window type unit.
When buying an AC unit, you should look for the cost per BTU first. Most often, window type air conditioners are much cheaper than a portable air conditioner of the same BTU rating. The reason for that is simple: portable air conditioners are cheaper and much more accessible than that of a window type, and you can move it around the house.
Here is a BTU rating chart:

BTUsAreaBest ForIdeal AC
5,000 to 9,000100 to 400 square feetSmall homes, room air conditioning, apartmentsPortable and window types
9,000 and above450 square feetMedium to large homes, business establishmentsCentral and ductless ACs

Q: Which is more comfortable to use: the portable AC or the window type AC?
A: Most people find that the portable AC is a lot easier to use and more suited for most homes, because they can be moved around to any room without having to install it permanently onto a window. Portable ACs may be pricey but they are super convenient.
Q: Why do modern air conditioner units use R410A refrigerants?
A: The R410A refrigerant is the new standard for refrigerants on newer air conditioners. With the pull out of harmful refrigerants like CFC and HCFCs, air conditioners and fridges today use a more eco-friendly solution in terms of keeping your indoor air cool and comfortable.
Q: How can a thermostat help you save energy?
A: By programming a thermostat for your air conditioner unit, you are saving a lot of cents or even dollars because you can program the air conditioner to go on low power when it’s night time when you are asleep. You can also program the AC unit to go on low or off when you are outside the house or somewhere else.
Q: Why should not go too low on your AC unit’s thermostat setting?
A: Having a thermostat setting that is too low can be not effective for cooling down your home. This is because the unit will operate faster than ever and thus, not really remove the humidity at hand.
Q: Can natural ventilation at night help reduce on air conditioning operation costs?
A: Yes, natural ventilation such as opening the windows at night during the summer can be helpful if you want to save up on energy costs when you have an AC at home or wherever you stay in. Air conditioning is only best during warm times in the daytime but can be turned lower or off during the night when the air can be cold outside. This helps your unit to get breaks from your everyday use.
Q: To reduce my AC unit’s operation costs, what simple lifestyle changes can I do to help?
A: If you want to save up on energy costs then you may want to use your AC unit sparingly during peak times. You can do this by bathing more often in the summer and eating ice cream.
If your bed sheets and pillow cases can fit in the freezer, you can also freeze them before you go to bed to help you sleep better at night. Cooler clothing can also benefit you during the summer so you don’t have to turn the AC on all the time.
Q: Can a house fan be a supplement cooling appliance to my air conditioner?
A: Yes, house fans can be used alongside air conditioners or after they have been used, so as not to overwork your air conditioner at all. Most ACs do have fan modes but it is better that you use a different fan for the job so you don’t expend too much power with the AC unit at all.
House fans can help save up on the operational costs of your air conditioners because they consume far less energy compared to that of an AC unit. This is why you may still need to prepare some house fans when you need to get ready for a really hot and humid summer season, especially if you live in a tropical area or live near the beach.
Q: Which is better for an AC unit: mechanical controls or electronic controls?
A: Choosing between mechanical and electronic controls is like choosing between a mechanical dial for your microwave or a digital keypad for its operation. Mechanical controls are great for ease of use while electronic controls are great for precise temperatures. Most people with accessibility problems can benefit more on mechanical controls while electronic controls work best for specific temperature needs.
Q: What is a good EER rating of any air conditioner to be energy efficient?
A: The EER or energy efficiency ratio is what measures the energy efficiency of an air conditioner. At least an EER of 12 should be sufficient for an air conditioner. When it comes to the SEER or seasonal energy efficiency ratio (which is mostly for year-round ACs), it should be at least 18 or greater. Higher EERs mean that they are more energy efficient for your home.
Q: How is a through the wall air conditioner different from a window type?
A: A through the wall AC unit works much like a window type, except that it only goes through the hole in the wall of your house. The downside, of course, is that you have to find some guy to make a hole in the wall, which can be frustrating if your house isn’t designed for an air conditioner like that. Its permanent installation also means that you can’t move it from place to place.
Q: Is air conditioning considered a luxury?
A: It depends on your needs but if you live in a poor country, air conditioning is considered a luxury. However, if you live in a slightly more modern country, air conditioning is not a big deal. Moreover, certain businesses require AC units for their business nature (e.g. groceries) and some people with respiratory problems also need an AC unit to help them alleviate the symptoms.
Q: What makes air conditioning so expensive?
A: Aside from the unit, if you don’t know how to install an AC unit then hiring an HVAC professional can be pricey because they are licensed and passed certain training. DIY installation can also lead to problems so it’s best to leave it to a professional. AC units have specialized parts and a motor that make them far more expensive than house fans.
