Eight months of heat, and winter nights that don't let up
Furnaces here run from October through May. That's eight months a year the burner has to work, with winter nights averaging 20°F. A furnace installed right has to hold that line night after night, not just get through the cold snaps.
Dutchess County has seen 28 winter storms and 341 damaging wind events over the past ten years, and 11 percent of New York households lost power for at least 24 hours in 2024. A new furnace should be able to start back up on its own when the power comes back. Fuel oil heats 44.1 percent of homes here, so a replacement furnace needs to match the fuel already running to the house. Any new gas furnace also has to meet the federal minimum of 80.0 percent AFUE, the baseline for how much of the fuel it burns turns into heat instead of going up the flue.

- What size furnace does my house need?
- It depends on a load calculation, not a chart based on square footage. A contractor figures this out by looking at your insulation, your windows, your ceiling height, and how much air your house loses, then runs the numbers to find the right output in BTUs. Too big and the furnace short cycles, heating the air fast but never running long enough to feel even. Too small and it runs constantly trying to keep up on those 20°F nights. Ask whoever quotes the job to show you the load calculation, not just a number they're used to installing.
- How do I know it's time to replace my furnace?
- Age is one of the first things to look at, along with how the furnace has been running lately. A furnace that's been in the house a long time is working harder to do the same job it used to do easily. Watch for rooms that won't heat evenly, a burner that cycles on and off more than it used to, or a gas bill that keeps climbing even though nothing else changed. With homes here needing heat from October through May, a furnace that's already struggling in the fall isn't going to make it through a full winter without a breakdown on a night near 20°F. If a repair is going to cost close to what a new unit runs, replacing it is usually the better call.
- Is a high-efficiency furnace worth it?
- It depends on how long you plan to stay in the house and what you're heating with now. Every non-weatherized gas furnace built since November 2015 has to hit at least 80 percent AFUE, so even a standard furnace today wastes less fuel than an older one might have. A high-efficiency model goes beyond that minimum, pulling more heat out of the same amount of gas, which matters more here since homes need heat for 8 months of the year. If you're currently heating with fuel oil, which 44.1 percent of households here still do, switching to a high-efficiency gas furnace can mean a real difference in how much fuel you burn each winter. A contractor can run the numbers for your specific house and fuel source.
