How can I be sure my unit is the right size?

Obviously, an air conditioner that’s too small won’t keep your home sufficiently cool. But what many don’t realize is that an oversized system will cycle (turn on and off) more than necessary, wasting expensive energy and possibly putting undue strain on the compressor. A-1 Heat & Air will determine the optimum size for your home by making a careful study of your cooling requirements. Window dimensions and exposure. Floor space, insulation and local climate. Heat-generating appliances. The direction your home faces. Even the amount of your home’s exterior shaded by trees.

We’ll specify the cooling capacity of the system in either Btu/h (British thermal units of heat removed per hour) or refrigeration tons (one ton being equal to 12,000 Btu/h).
