Lynn asks a lot of a furnace
Your furnace in Lynn runs October through May. That's 8 months of the year, with winter nights averaging 21°F. A new furnace has to be sized to hold the house warm through that whole stretch, not just the coldest week.
Most homes here heat with gas, and any new gas furnace has to meet the federal minimum of 80 percent AFUE. Power is worth planning around too. Ten percent of Massachusetts households lost power for 24 hours or more in 2024, and the state has logged 54 winter storms and 256 damaging wind events over the past ten years. Whoever installs your furnace should plan for a house that may lose power on a cold night, not just for the mild ones.

- What size furnace does my house need?
- The right size comes from a room by room heat loss calculation, not the square footage of your house alone. A contractor factors in your insulation, window count and type, ceiling height, and how much cold air gets in around doors and framing. Two houses the same size can need different furnaces because one holds heat better than the other. With winter lows here averaging 21°F, an undersized furnace will run constantly and still fall short on the coldest nights, while an oversized one cycles on and off too often and wears out faster. A contractor will run the calculation and size it to your house.
- How do I know it's time to replace my furnace?
- Watch for uneven heat between rooms, a furnace that cycles on and off more than it used to, or a heating bill that keeps climbing without a clear reason. Rust near the burner, a yellow flame instead of blue, or soot around the unit are signs worth having checked right away. Age matters too. Homes here need heat for 8 months of the year, October through May, so a furnace works harder and longer than it would somewhere with a shorter winter. If yours is getting old and repairs are becoming more frequent, replacement usually makes more sense than another repair bill.
- Is a high-efficiency furnace worth it?
- It depends on how many months a year your furnace runs and what you're replacing. Every non-weatherized gas furnace made since November 2015 has to reach at least 80 percent AFUE, so even a standard model today wastes less fuel than an older one might. A high-efficiency furnace goes beyond that minimum, which matters more here since homes need heat from October through May, 8 months of the year. Most households in this area heat with gas, so a more efficient furnace has a long season to make a difference. A contractor can walk you through the options and what fits your house.
