Whether you’re building a new home or upgrading your existing air conditioning system, there is one question you’re definitely going to consider: what size air conditioner do I need? Buying the right air conditioner size is a balancing act. Too large, and you could experience poor humidity control and significant energy costs. Too small, and the unit might fail to reach 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 conditioning can generate the right cooling capacity is a matter of comfort and keeping your energy bills low. Here’s why you shouldn’t merely guess the correct AC size:
Cooling capacity is expressed in British thermal units (BTUs). A BTU is a standard unit of energy that indicates the amount of heat an air conditioner can remove in one hour. The majority of room AC units range from 5,000 to 18,000 BTUs. Because central air conditioners are larger, they’re usually measured in tons. A one-ton system is proportionate to 12,000 BTUs. Generally, central AC systems range from 1 to 5 tons.
When considering window or portable air conditioners, which size you need mainly depends on the room’s square footage. Measure the area—length x width—and match it to the appropriate BTUs:
These general recommendations don’t account for factors like interior heat gain or whether or not you have any shade trees around your home to block out the sun. For a more precise calculation, seek expert advice from Service Experts Heating, Air Conditioning & Plumbing.
Determining the perfect size of central air conditioner begins with the home’s square footage, but correct sizing requires a more in-depth look. HVAC professionals rely on load calculations outlined in Manual J to determine a home’s specific cooling requirements. Here are the considerations that come into play:
