Newbury summers don't push an air conditioner hard
Summer afternoons here average 77 degrees. A new system in Newbury isn't working against the kind of heat that keeps a compressor running all day.
Any new central air system installed since 2023 still has to meet the federal efficiency minimum of 13.4 SEER2, whatever size fits your house. The outdoor condenser will also sit through Orange County's weather year-round, including the wind and hail that show up here, so how it's installed and secured outside matters.

Vermont has no state license for HVAC contractors.
There is no state licensing board keeping a file on the contractor coming to your house, and no state test they had to pass to do this work. Vermont leaves HVAC contracting alone, so nothing about this job gets checked at the state level before or after it happens.
What stands in for that here is the permit. In most cities and counties, putting in a new air conditioner needs a permit from the local building office, and the work gets inspected once it is done. That inspection is what confirms the unit is wired and set up the way it should be, not a license.

- What size air conditioner does my house need?
- The right size depends on your square footage, ceiling height, insulation, window area and how much shade your house gets, not just a rule of thumb per square foot. A contractor works this out with a load calculation, walking through the house and doing the math room by room. An oversized unit cools the air fast but shuts off before it pulls the moisture out, so the house feels clammy. An undersized one runs constantly and still can't keep up on the hottest afternoons. With summer highs here averaging around 77°F, the load is lighter than in hotter regions, but the calculation still has to match your specific house.
- 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 only the outdoor unit usually causes problems. The two are matched to work at a specific capacity and airflow, and pairing an old coil with a new condenser can mean poor performance or a warranty that won't hold. If the coil is already leaking or near the end of its life, it makes more sense to replace both at once. A contractor can look at the age and condition of what's there and tell you which situation you're in.
- Do HVAC contractors in Newbury 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. Asking a contractor about their experience and how they handle the permit is a reasonable way to check who you're hiring.
