Eight months of heat, and winters that don't let up
New Bedford needs a furnace from October through May, eight months of the year. Winter nights average 23°F here, so a new furnace has to hold up through a long, cold season, not just a few hard nights.
Most homes in the area heat with gas. Any non-weatherized gas furnace built since November 2015 has to reach at least 80 percent AFUE. That is the floor, not a target, and the unit going into your home should clear it.

A high-efficiency gas furnace would save about $160 a year to run in Bristol County compared with a gas furnace.

- What size furnace does my house need?
- The right size comes from a heat loss calculation on your specific house, not from square footage alone. A contractor will look at your insulation, your windows, your ceiling height, and how the house is laid out before landing on a number. A furnace that is too big cycles on and off too fast and never runs long enough to heat evenly. Too small, and it will run nonstop trying to keep up on a night near 23°F and still fall short.
- How do I know it's time to replace my furnace?
- If your furnace is struggling to keep the house warm through the cold months, or you are calling for repairs more winters than not, it is time to start planning a replacement. Watch for uneven heat between rooms, a furnace that runs long cycles without shutting off, or a rise in gas use with no other explanation. Age matters too. Furnaces here need to work reliably from October through May, so a unit on its last legs heading into that stretch is a risk worth acting on before the cold sets in rather than during it.
- Is a high-efficiency furnace worth it?
- It depends on how many months your furnace has to run and what you are replacing. With heat needed here eight months a year, a furnace spends a lot of its life working, so efficiency gains add up more than they would somewhere with a short winter. Any new non-weatherized gas furnace sold now has to hit at least 80 percent AFUE, so the real question is whether to go higher than that minimum. A contractor can walk through the options against your current furnace's efficiency and what your house needs.
