What a new system in Stamford has to handle
Winter nights here average 22°F from December through February, and heat is running somewhere in the house from October through May. That is 8 months of the year on the heating side alone. Add June through August, when afternoons average 81°F and the system switches to cooling, and the equipment is working 11 months out of the year. A new furnace or heat pump has to be sized for both jobs, not just the one you're replacing it for.
A lot of homes in this area heat with fuel oil, 36% of them. Whatever you install next should fit the fuel and ductwork already in the house, or the installer needs to plan for what changes if it doesn't. And with 20% of Connecticut households losing power for at least 24 hours at some point in 2024, it's worth asking how your new system starts back up once the power does.

Connecticut requires HVAC contractors to hold a state license.
Connecticut tests contractors before granting that license, and the Department of Consumer Protection keeps a record of who holds one. That record follows the contractor from job to job, not the other way around. A license does not mean a particular installation was checked, only that the person or company doing it has met the state's requirements to work in the trade.
For this job, the license accounts for the contractor. It does not cover what happens on installation day. In most cities and counties, replacing a heating and cooling system needs a permit from the local building office, and the finished work gets an inspection.

- When should I replace my HVAC system?
- Replace it when repairs start coming often, or when the unit is old enough that another breakdown feels like a matter of time. Furnaces and air conditioners both tend to last a couple decades, but the years add up faster on a furnace here since homes need heat from October through May. If yours is struggling to keep up on the coldest nights, when it's 22°F outside, that's a sign it's losing the fight, not just having a bad night. A contractor can look at the age, the repair history, and how it's running now and tell you if replacing makes more sense than fixing it again.
- Should I replace my furnace and air conditioner at the same time?
- If they're close in age, it often makes sense to plan for both, but it depends on the condition of each one. A furnace and air conditioner installed together are matched to work with each other, and pairing an old unit with a new one can mean the new one never runs at its best. Homes here need heat for 8 months and cooling for only 3, so the furnace usually carries the heavier load and wears faster. Have a contractor check both systems and tell you honestly whether one, or both, need to go.
- 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. For a furnace, that includes venting it properly and checking the gas connection or wiring. For an air conditioner, it means connecting the refrigerant lines and setting the outdoor unit level on its pad. Once everything's connected, the contractor tests the system, checks airflow, and confirms it's heating or cooling the way it should before calling the job done.
