A furnace built for ten months of work
Dover-Foxcroft asks a lot of a furnace. Winter nights average 6°F, and homes here need heat from September through June, ten months a year. That is a long, cold season, and the furnace you choose has to run through most of the year without much rest.
More than half the homes in this area heat with fuel oil, so a new oil furnace has to be sized and installed to match a system that already fits your house. Power matters too. Over the past ten years the region has seen 147 winter storms and 61 damaging wind events. In 2024 more than half of Maine households lost power for at least 24 hours. A new furnace, and how it is wired to restart, should account for that. For a new gas furnace, federal rules set the floor. Any non-weatherized model made since November 2015 has to reach at least 80 percent AFUE.

- What size furnace does my house need?
- The right size depends on your home's square footage, insulation, window count, and layout, so there is no single number that fits every house. A contractor will run a load calculation that looks at all of that rather than square footage alone. Given how cold it gets here, with winter nights averaging 6°F, getting this right matters more than it would somewhere milder. A furnace that is too big will cycle on and off too often, and one that is too small will run constantly and still leave you cold.
- How do I know it's time to replace my furnace?
- Watch for rising repair bills, uneven heat between rooms, and a furnace that runs longer than it used to just to keep the house comfortable. Age matters too, and a furnace that needs frequent repair as it gets older is telling you something. Homes here need heat from September through June, so a furnace that struggles is putting in ten months of work every year. If a contractor tells you the cost to fix it is close to the cost to replace it, replacing usually makes more sense.
- Is a high-efficiency furnace worth it?
- It depends on how much you heat and what you are replacing. Since November 2015, non-weatherized gas furnaces have had to reach at least 80 percent AFUE, so even a standard new furnace wastes less fuel than an older one might. A high-efficiency furnace pushes that number higher still, and with heat needed here from September through June, those gains add up over a full season. More than half of homes here heat with fuel oil, so if you are weighing a fuel change alongside this decision, a contractor can walk you through what each option means for your specific furnace and home.
