Whether you’re building a new home or updating your existing HVAC system, there is one question you’re bound to ask: what size air conditioner do I need? Buying the ideal air conditioning size is a balancing act. Too large, and you could encounter poor humidity control and significant energy bills. Too small, and the unit might not be able to maintain comfortable temperatures on extremely hot days. Appropriate air conditioner sizing is required to enjoy an efficient, cost-effective and comfortable cooling experience.
Ensuring your air conditioning produces the perfect cooling capacity is a matter of comfort and cost savings. Here’s why you shouldn’t merely guess the ideal air conditioner 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. Most room air conditioning units range from 5,000 to 18,000 BTUs. Because central air conditioners are bigger, they’re commonly measured in tons. A one-ton system is equivalent to 12,000 BTUs. Most central AC units range from 1 to 5 tons.
When examining window or portable air conditioners, which size you need primarily depends on the room’s square footage. Measure the space—length x width—and match it to the appropriate BTUs:
