New Haven asks a system to work most of the year
Heat is needed here from October through May, eight months of the burner or the heat pump running on winter nights that average 25°F. Summer is shorter but it still counts. Afternoons average 81°F from June through August, and a system has to cool the house through all three months. Eleven months out of the year, a system here is doing one job or the other.
Nearly half the homes in New Haven heat with gas, and a new furnace has to meet the federal minimum efficiency standard. Power is worth asking about too. A fifth of Connecticut households went at least a full day without power in 2024, so it's worth knowing what your new system does when the power drops and comes back, whether it runs on gas or electricity.

Connecticut requires HVAC contractors to hold a state license.
Connecticut licenses HVAC contractors through the Department of Consumer Protection. That license belongs to the contractor, not to any one job, so it covers this installation the same way it covers the next one they do.
For a job like this, replacing a furnace, air conditioner, or heat pump, most cities and counties also require a permit from the local building office before the work starts and an inspection once it's finished. That permit and inspection are separate from the state license, and they are what confirms the finished install locally.

- When should I replace my HVAC system?
- Replace it when repairs get frequent, when the unit is old enough that parts are wearing out one after another, or when it can no longer keep the house comfortable on the coldest or hottest days. An aging furnace or air conditioner works harder to keep up even when it still runs, and that shows up in your bills before it fails outright. Homes here need heat from October through May, so a furnace on its last legs is not something to gamble on through those months. If you are already calling for repairs more than once a season, a contractor can tell you whether it makes more sense to replace than to keep patching it.
- Should I replace my furnace and air conditioner at the same time?
- If both are old, replacing them together often makes sense, but it depends on the condition of each unit. A furnace and air conditioner installed at different times can still work fine side by side as long as both are in good shape. Where it matters more is when one has already failed and the other is close behind it. A contractor looking at both units can tell you whether pairing the work saves you a second disruption down the road.
- What happens during an HVAC installation?
- A contractor removes the old equipment, sets the new furnace or air conditioner in place, and connects it to the ductwork, gas or electric line, and condensate drain. They check the ducts for leaks or sizing problems, since a new unit connected to bad ductwork will not perform the way it should. The system gets tested and the airflow and thermostat settings get adjusted before the job is called done. Homes here need heat or cooling most of the year, so the new system is set up to run through both winter nights near 25°F and summer afternoons near 81°F.
