Whether you’re building a new home or replacing your existing air conditioning system, there is one question you’re definitely going to ponder: what size air conditioner do I need? Selecting the correct air conditioning size is a balancing act. Too large, and you could experience poor humidity control and significant energy expenses. Too small, and the unit might not be able to maintain comfortable temperatures on scorching hot days. Proper air conditioner sizing is crucial to enjoy an efficient, cost-effective and comfortable cooling experience.
Ensuring your air conditioning produces the right cooling capacity is a matter of comfort and energy savings. Here’s why you shouldn’t merely guess the appropriate AC size:
Cooling capacity is calculated in British thermal units (BTUs). A BTU is a standard unit of energy that indicates the amount of heat an air conditioner can remove every hour. The majority of room AC units range from 5,000 to 18,000 BTUs. Because central air conditioners are bigger, they’re usually measured in tons. A one-ton system is comparable to 12,000 BTUs. Most central AC systems range from 1 to 5 tons.
For window or portable air conditioners, the right size primarily depends on the room’s square footage. Measure the room—length x width—and match it to the appropriate BTUs:
These general guidelines don’t account for factors like interior heat gain or how much sun streams in through the windows of the room. For a more exact calculation, seek expert advice from Service Experts Heating, Air Conditioning & Plumbing.
