In this post, we’re discussing room air conditioners. By the end of this article, you’ll have a better idea of the different types of room ACs available in the market today. You’ll also know what information need so that you can choose the right type and sized model for your home.
The first thing you’ll need to know are the measurements. Be sure to measure the window or wall opening and it helps to have a general idea of the room size you want to cool. You should also take into consideration thr ceiling height. The easiest way to check the square footage of the room is to measure the length of the floor and multiply it by the width and that will give you your room square footage based on an 8-foot ceiling.
Next, make sure a grounded outlet is next to the window or wall space you’ll be using for air conditioning. You should not use an adapter or extension cord. You should also know if the unit you purchase will run on 115 or 208/230 volt.
The next step is to ask yourself:
– If the room you’re trying to cool facing the sun the majority of the day
– Are the ceilings taller than 8 feet
– How many people are occupying the space
– Will this unit be placed in the kitchen
All of these things will affect your unit’s cooling capacity.
Types of Air Conditioners
You can choose from the four types of room air conditioners available on the market today: window, casement, wall, and portable.
Window ACs are the most common and are used with windows that slide up and down. Casement ACs are best for windows that slide left to right and usually with a hand crank. Wall ACs are also common and are installed through the wall of a building and require a sleeve. These sleeves are sold separately and can be found in the air conditioning accessories guide. And finally, portable air conditioners can be used in a windowless room or office, although a room with a window is recommended for venting since the exhaust needs to go somewhere outside the room.
All of these units come in different sizes, with cooling capacities ranging from 5000 to 30,000 BTUs. The size you need will depend on the room to be cooled. If you incorrectly choose an air conditioner that has a higher BTU rating than what the room size requires, it will tend to cycle off too quickly and the unit will not properly remove the moisture from the air, leaving the room feeling humid.
On the other hand, if you choose a unit that has a lower BTU rating than what the room size requires, the unit will run continuously and will not adequately cool the room. Just be sure to check the unit’s energy efficiency rating, labeled as EER, which is posted on every air conditioner. This will let you know the approximate yearly savings you’ll receive on energy star appliance. The higher the EER rating, the greater the savings.
