Three months of real work, not much more
Norwich asks for cooling from June through August, with summer afternoons averaging around 80°F. That is a short season compared to a lot of the country, and it means a new system here spends most of the year doing nothing at all.
Any central air conditioner installed new has to meet 13.4 SEER2, the federal minimum that took effect in 2023. With a season this short, sizing it right matters more than chasing a rating above that minimum. A unit that fits the house will handle those 80°F afternoons without trouble.

Connecticut requires HVAC contractors to hold a state license.
The Department of Consumer Protection tests and licenses HVAC contractors in Connecticut, and the license belongs to the contractor, not to any single job. That means the state has checked this contractor's qualifications before they ever set foot in Norwich, and keeps a record of who holds that license.
For an air conditioner installation, the license is what stands behind the person doing the work, but it is not the only check on the job itself. In most cities and counties, this kind of installation also needs a permit from the local building office, with an inspection once the work is done, and that is a separate process from state licensing.

- What size air conditioner does my house need?
- It depends on your square footage, how much shade your house gets, how well it's insulated, and how many windows face the sun. There's no single number that fits every home. Two houses of the same size can need different sized units. A contractor will do a load calculation on your actual house to get this right, and with summers here running June through August, getting the size right matters more than going bigger just in case.
- Should I replace the whole system or just the outdoor unit?
- In most cases, if the outdoor unit is failing, the indoor coil should be replaced with it. New outdoor units run on different refrigerant and different efficiency levels than older ones, and matching a new condenser to an old coil often means the system never runs the way it's rated to. A contractor can look at the age and condition of the indoor coil and tell you whether it's worth keeping.
- Do HVAC contractors in Norwich need a state license to work on my home?
- Yes. Connecticut requires HVAC contractors to hold a state license, issued by the Department of Consumer Protection. Ask to see it before work starts. It's a fair question and any licensed contractor expects it.
