Bridgeport furnaces run eight months of the year
From October through May your furnace is the only thing standing between your house and a Bridgeport winter. Nights average 26°F through those months, cold enough that a furnace runs long hours night after night, not just on the coldest days.
Any gas furnace installed today has to reach at least 80 percent AFUE. That is the federal minimum, and 57.4 percent of homes here already heat with gas, so this is the standard a new furnace has to clear before it earns anything better.

Connecticut requires HVAC contractors to hold a state license.
The license is held by the contractor, not issued job by job. Connecticut's Department of Consumer Protection tests and records the people who hold it, so the license follows the business across every furnace it installs, not just this one.
For a furnace installation in Bridgeport, that license is what stands behind the work, but the job still gets a second check. The city's building office requires a permit for a furnace replacement and an inspection once it's done, which is where the gas connection and venting get looked at by someone other than the installer. Most homes here heat with gas, so that inspection is doing real work.

- What size furnace does my house need?
- The right size depends on your square footage, your insulation, your windows, and your home's layout, so there's no number that applies to every house. A contractor works this out with a load calculation, not a chart based on square footage alone. Getting this right matters more than usual here, since these homes need heat from October through May. Too big and it cycles on and off without warming things evenly. Too small and it runs constantly through the coldest stretch without keeping up.
- How do I know it's time to replace my furnace?
- The clearest signs are age, repeated repairs, and rooms that will not heat evenly no matter what you do. Once a furnace gets old enough, parts wear out faster than they're worth fixing one at a time. If a technician has been out more than once this winter for the same unit, that's usually the point to stop repairing and start planning a replacement. With winter lows here averaging 26°F, a furnace that struggles now will only get worse as the season goes on.
- Is a high-efficiency furnace worth it?
- It depends on how long you plan to stay in the house and how much you're paying to heat it now. Every non-weatherized gas furnace sold new today has to hit at least 80 percent AFUE, so even a standard replacement is more efficient than an older unit. High-efficiency models go higher than that, which matters more in a place where heat runs from October through May than it would somewhere with a short winter. A contractor can look at your current furnace and your gas bills and tell you whether the jump in efficiency pays for itself in your situation.
