Two months of real heat is all Rochester asks of it
Summers here are short. Cooling season runs July through August, with afternoons averaging 79°F, and that is the whole job for a new system. It does not need to hold up against months of hard heat, just those weeks when the house needs relief.
Wind is the bigger factor over time. Monroe County has logged 154 damaging wind events over the past ten years, against 15 hail events with hailstones no larger than an inch. An outdoor unit sits outside through all of that, so how it is anchored and installed matters as much as the equipment itself. Any new central air conditioner built since 2023 also has to meet a federal minimum of 13.4 SEER2, so that efficiency level is the starting point, not an upgrade.

- What size air conditioner does my house need?
- The right size depends on your square footage, your insulation, how many windows you have, and which way your house faces. There's no single number that fits every home. A contractor works this out with a load calculation, not a chart based on house size alone. Going bigger than you need isn't a safety margin. An oversized unit cools the air fast then shuts off before it pulls the humidity out, so the house feels clammy even at the right temperature. With only July and August to worry about here, it's worth getting the sizing right rather than guessing high.
- Should I replace the whole system or just the outdoor unit?
- In most cases, if the outdoor unit needs replacing, the indoor coil should go with it. The two are matched to work together, and pairing a new outdoor unit with an old indoor coil often means you don't get the efficiency or the cooling performance you paid for. Refrigerant type is part of this too. If your system is old enough to use R-22, a new outdoor unit won't run on it at all. A contractor can look at the age and condition of both parts and tell you whether the coil is worth keeping.
- Do HVAC contractors in Rochester need a state license to work on my home?
- Ask to see a current license before any work starts on your home. 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. A licensed contractor should have no trouble showing you the number, and you can confirm it's valid before you agree to the job.
