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 right AC size is a balancing act. Too large, and you could face poor humidity control and exorbitant energy bills. Too small, and the unit might fail to provide comfortable temperatures on scorching hot days. Proper air conditioner sizing is required to enjoy an efficient, cost-effective and comfortable cooling experience.
Ensuring your air conditioner provides the right cooling capacity is a matter of comfort and cost savings. Here’s why you shouldn’t merely guess the ideal AC size:
Cooling capacity is calculated in British thermal units (BTUs). A BTU is a standard unit of energy that conveys the amount of heat an air conditioner can remove per hour. Most room air conditioners range from 5,000 to 18,000 BTUs. Because central air conditioners are more powerful, they’re typically measured in tons. A one-ton system is equivalent to 12,000 BTUs. Most central air conditioning models range from 1 to 5 tons.
For window or portable air conditioners, sizing primarily depends on the room’s square footage. Measure the area—length x width—and match it to the appropriate BTUs:
