Two months of heat, but it still has to keep up

Jamestown only asks for cooling from July through August. Summer afternoons average 78°F, which is mild next to most of the country, but a new system still has to be sized right for those weeks or it will run harder than it should.

Any central air conditioner installed today has to meet 13.4 SEER2, the federal minimum, so the efficiency floor is already set. The outdoor unit also has to sit outside through what the weather brings the rest of the year. Chautauqua County has logged 253 damaging wind events and 21 hail events over the last ten years, with hail up to 2 inches, so the cabinet and coil need to hold up to that even in the months the system is not cooling anything.

What size air conditioner does my house need?
The right size depends on your square footage, your ceiling height, how much shade your house gets, and how well it holds cool air. A contractor figures this out with a load calculation, not just a formula based on square feet. Too big a unit cools the air fast but shuts off before it pulls the humidity out, so the house feels clammy. Too small and it runs constantly without ever catching up, especially with summer afternoons here averaging 78°F.
Should I replace the whole system or just the outdoor unit?
If your indoor coil and outdoor unit are different ages or different refrigerant types, replacing just the outdoor unit usually is not an option. The two are matched to work together, and pairing a new condenser with an old coil can mean it never reaches the efficiency it is rated for. Sometimes it will not run right at all. If the coil and the outdoor unit are close in age and the coil is still in good shape, a contractor can tell you whether it is safe to replace only the outdoor unit.
Do HVAC contractors in Jamestown need a state license to work on my home?
Yes, HVAC contractors need a state license to do this work legally. A license means the contractor has met the state's requirements for training and insurance, which matters if something goes wrong with the installation later. Ask to see the license number before work starts, and you can check it against the state's licensing board.
