Bellows Falls doesn't ask much of an air conditioner, but what it asks, it means
Summer afternoons here average 77°F. That's not extreme heat, but it's steady, and it's the reason a new system needs to be sized to the house it's cooling, not oversized on the assumption that Vermont summers need a bigger machine to fight back against.
Windham County has also logged 143 damaging wind events and 5 hail events over the past ten years, so an outdoor condenser here needs to be installed and anchored with that in mind. And if you're installing new, federal rules require at least 13.4 SEER2, so whatever goes in will meet that mark or beat it.

Vermont has no state license for HVAC contractors.
There's no state licensing board keeping a record of HVAC contractors here, so there's no state exam behind the person doing this installation and no state license number to check. Vermont doesn't register these contractors either. Whatever confidence you have in the person doing this work comes from somewhere other than a state record, because Vermont doesn't keep one.
In most Vermont towns, installing an air conditioner needs a permit from the local building office, with an inspection once the work is done. That inspection is what checks the installation itself, the wiring, the disconnect, the way the unit is set and connected, not who the contractor is.

- 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 they face, and your ceiling height. A unit that's too big will cool the room fast but shut off before it pulls the moisture out of the air, so the house feels damp. A unit that's too small will run all afternoon and never quite catch up. A contractor will run a load calculation on your actual house rather than guess from square footage alone, since summer afternoons here average 77°F and that number feeds into the calculation too.
- Should I replace the whole system or just the outdoor unit?
- If your indoor coil and outdoor unit are matched and both still in good shape, replacing just the outdoor unit can work. But the two are designed to work as a pair, and putting a new outdoor unit on an old indoor coil often means they don't perform the way either was rated to. New units also have to meet the 13.4 SEER2 minimum that took effect in 2023, and an old coil may not be built to work with that efficiency level. A contractor can check whether your coil is a match before deciding.
- Do HVAC contractors in Bellows Falls 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 in most cities and counties still needs a permit from the local building office, and the work gets inspected once it's done.
