Whether you’re building a new home or replacing your existing HVAC system, there is one question you’re guaranteed to ask: what size air conditioner do I need? Buying the right AC size is a balancing act. Too large, and you could encounter poor humidity control and excessive energy bills. Too small, and the unit might not be able to maintain comfortable temperatures on extremely hot days. Correct air conditioner sizing is required to enjoy an efficient, cost-effective and comfortable cooling experience.
Ensuring your air conditioning provides the perfect cooling capacity is a matter of comfort and cost savings. Here’s why you shouldn’t just guess the appropriate air conditioning system 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 per hour. Most room air conditioning units range from 5,000 to 18,000 BTUs. Because central air conditioners are bigger, they’re typically measured in tons. A one-ton system is proportionate to 12,000 BTUs. Generally, 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:
These general tips don’t take into account factors like interior heat gain or how much sun streams in through the windows of the room. For a more accurate calculation, reach out to an HVAC professional from Service Experts Heating, Air Conditioning & Plumbing.
Identifying the right size of central air conditioner begins with the home’s square footage, but correct sizing requires a more in-depth look. HVAC specialists rely on load calculations explained in Manual J to determine a home’s particular cooling requirements. Here are the factors that technicians will examine:
