Two months of real heat, then it's done
St. Albans doesn't ask much of an air conditioner. Summer afternoons average 76°F, and homes here only need cooling in July and August. That's a short season, but the storms that come through it are not gentle. Franklin County has logged 67 damaging wind events and 9 hail events over the past ten years, with hail up to 1.5 inches. An outdoor condenser sits outside through all of that, so a new one needs to handle wind and hail, not just heat.
Any new central air conditioner installed today has to meet a federal minimum of 13.4 SEER2. That's the baseline, not a special upgrade, and it applies whether you're replacing a unit or putting in central air for the first time.

Vermont has no state license for HVAC contractors.
There is no license or registration to check anywhere in Vermont. No state office tests HVAC contractors, files their business, or keeps a record of who is doing this work in your home. That is true whether the job is small or large, in Franklin County or anywhere else in the state.
For this job, the protection comes from the local building office instead. In most cities and counties, installing a new air conditioner needs a permit, and an inspection once the work is done. That inspection is what checks the work was done right, since no state license stands behind it here.

- What size air conditioner does my house need?
- The right size depends on your home's square footage, its insulation, how many windows it has and which way they face, and a few other details, so there's no number that works for every house. A contractor figures this out with a load calculation, not by guessing from square footage alone. With only 2 months of real cooling weather here and summer afternoons averaging 76°F, an oversized unit will short cycle instead of running long enough to pull moisture out of the air. Getting the size right matters more than most people expect, since too big is just as much a problem as too small.
- 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, replacing just the outdoor unit usually causes problems down the road. Manufacturers match the coil and the condenser for a reason, and pairing an old coil with a new condenser can hurt efficiency and shorten its life. New units built since 2023 also have to meet a 13.4 SEER2 minimum, and an old coil isn't built to work with that rating. A contractor can look at the age and condition of both pieces and tell you whether a full system swap makes more sense here.
- Do HVAC contractors in St. Albans need a state license to work on my home?
- No. Vermont has no state license or registration for HVAC contractors doing home work. That doesn't mean there's no oversight on the job itself. Installing an air conditioner typically needs a permit from the local building office, and the work gets inspected once it's done, so check that whoever you hire is pulling that permit.
