A short cooling season, but real heat while it lasts
Westerly only needs air conditioning in July and August. That is a short stretch, but summer afternoons still average 79°F, and a new system has to be sized right to handle that heat without running longer than it should.
Any new central air conditioner installed here has to meet the federal minimum of 13.4 SEER2. That is the baseline for new equipment now, whether you are replacing an old unit or putting in central air for the first time.

Rhode Island requires HVAC contractors to hold a state license.
The license is issued to the contractor, not to the job, so it covers the business behind the work rather than this specific install. It is handled through the Department of Labor and Training.
For an air conditioner install, that license is what stands behind the work itself. In most cities and counties, the job also needs a permit from the local building office and an inspection once the install is done. That permit and inspection check the work. The license is what stands behind who is doing it.

- What size air conditioner does my house need?
- The right size depends on your home's square footage, how much sun hits it, your ceiling height, and how well it's insulated, not just a rule of thumb. An undersized unit will run constantly and never quite cool the house. An oversized one cools too fast, shuts off before it pulls the humidity out, and leaves the air feeling damp. A contractor will do a load calculation on your actual house to get this right, since summer highs here average 79°F and the system still needs to keep up on the hottest afternoons.
- Should I replace the whole system or just the outdoor unit?
- If your indoor coil and outdoor unit are matched and both in good shape, replacing just the outdoor unit can make sense. But if the system is old, the two parts often aren't compatible with each other once one is swapped for a newer model, and mismatched equipment won't perform the way either piece was designed to. A contractor can check whether your indoor coil will pair with a new outdoor unit or whether the whole system needs to come out together.
- Do HVAC contractors in Westerly need a state license to work on my home?
- Yes. Rhode Island requires HVAC contractors to hold a state license, issued through the Department of Labor and Training. The license covers the contractor, not the specific job, so it's worth confirming before work starts rather than after. Installing an air conditioner also typically needs a permit from the local building office and an inspection once the work is done, separate from the contractor's license.
