Two months of real heat, then it sits idle

Summer here runs short. Homes need cooling for July and August, with afternoons averaging 79°F. A new air conditioner spends most of the year doing nothing, then has to work through those two months without trouble.

Any new central air conditioner installed now has to meet 13.4 SEER2, the federal minimum. Niagara County also sees its share of hail and wind, seventeen hail events and 87 damaging wind events over the last ten years, with hail up to 2.5 inches recorded. The outdoor unit sits exposed to that, so it needs to be installed where it has some protection and can be checked after a bad storm.

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's insulated, so there's no single number that fits every home. A contractor works this out with a load calculation, not a tape measure and a guess. Too big and it cools the air fast but shuts off before it pulls the moisture out, so the house feels damp. Too small and it runs the entire afternoon without catching up. With summer highs around 79°F here, an undersized unit will struggle more than it would somewhere cooler, so getting the size right matters.
Should I replace the whole system or just the outdoor unit?
If your indoor coil and outdoor unit were installed together and are close in age, replace both at the same time. Mixing an old coil with a new outdoor unit can leave you with a mismatched system that doesn't reach its rated efficiency and may void the warranty on the new part. The coil and the compressor are matched to work as a pair. A contractor can check your indoor coil's age and condition and tell you whether it's worth keeping.
Do HVAC contractors in Niagara Falls need a state license to work on my home?
Yes, HVAC contractors doing this work need to be licensed. A license means the contractor has met the training and testing requirements to install and service air conditioning systems, and it's worth asking to see it before any work starts on your home.
