Nine months of heat, and winter nights near 16°F
Pittsfield needs a furnace from September through May. That's nine months out of the year the burner is doing real work, not just taking the edge off on a few cold mornings. Winter nights here average 16°F, and a furnace sized and installed right is what keeps a house livable through that.
Any gas furnace installed now has to hit at least 80 percent AFUE, the federal minimum since 2015. That's the floor, not a selling point, but it's worth knowing so you can see where a unit stands against it. Power is worth planning around too. Statewide, 10 percent of Massachusetts households went at least 24 hours without power in 2024, and the winters here bring the kind of storms that cause that. A furnace that runs on gas heat still needs electricity to run its blower and controls, so an outage takes it down with everything else.

- What size furnace does my house need?
- The right size comes from a load calculation, not a formula based on square footage alone. A contractor measures your walls, windows, insulation, and ceiling height, then figures out how much heat escapes on a cold night. With winter lows here averaging 16°F, a furnace that's too small will run constantly and still leave rooms cold, and one that's too big will short cycle and wear out faster. Ask the contractor for a written load calculation before they quote a size.
- How do I know it's time to replace my furnace?
- Age is one sign, but how the furnace is running matters more. Rising repair calls, uneven heat between rooms, and a furnace that takes longer to reach the same temperature all point the same way. Homes here need heat from September through May, so a furnace on its way out gets tested nine months of the year, not just in the coldest weeks. If yours is struggling now, it will struggle more on a 16°F night.
- Is a high-efficiency furnace worth it?
- It depends on how long you plan to stay in the house and what furnace you have now. Furnaces built since November 2015 already have to hit 80 percent AFUE, so the real question is whether stepping up further makes sense for your situation. A high-efficiency furnace pulls more heat out of the same fuel, which matters more in a place where the heating season runs nine months a year. A contractor can walk through the options and what each one means for your house specifically.
