Homeowners often wonder which type of air conditioner units are suitable for the specific needs of their household. The first and most important thing when choosing an air conditioning systems is getting the right sized unit that will not only keep you comfortable, but will also be the most energy efficient solution. An air conditioner that is too small will not be powerful enough to provide enough cool air, while an air conditioner that is too big for your home will consume too much electricity and will deliver excessive humid air.
In order to decide which types of air conditioner units are most suitable for your home, work with an air conditioning expert to determine the total square footage of the space you intend to cool. Next, you need to determine whether you want a single air conditioner unit or you wish to install central air to serve the entire home. Central air is more efficient from many different points of view, but it is especially recommended for energy efficiency, low noise levels, convenience of cooling the entire house simultaneously, and highly efficient filters that provide better indoor air quality. Plus, central air increases your home’s market value.
Next, you must determine the cooling capacity that you require for your home. The cooling capacity of both central and room air conditioning is measured using British Thermal Units, informally known as BTUs. Depending on your square footage, you can select a cooling capacity that will provide you with the right amount of fresh, cooled air throughout those hot summer days.
Here is a basic guide of recommended cooling capacity depending on square footage:
- 100 to 300 square feet – 5,000 -7,000 BTUs
- 300 to 550 square feet – 8,000 – 12,000 BTUs
- 550 to 1,000 square feet – 14,000 – 18,000 BTUs
- 1,000 to 1,200 square feet – 21,000 – 24, 000 BTUs
- 1,500 to 2,000 square feet – 30,000 BTUs
- 2,000 to 2,500 square feet – 34,000 BTUs
In addition to these simple calculations, you also need to take into account the following factors that may influence the cooling capacity of your air conditioner:
- Eliminate spaces that do not require cooling (basement) in your total square footage;
- Take into account the heat loss calculation performed by an expert
- Reduce the cooling capacity by 10% if the room you intend to cool is shaded;
- Increase the cooling capacity by 10% if the room you intend to cool receives full sun;
- Add 600 BTUs for each extra person that lives in a space
