Brockton asks a furnace to run eight months of the year
From October through May, your furnace is what keeps the house livable. Winter nights average 23°F, so once it starts running most mornings, it doesn't get much of a break until spring.
Massachusetts also loses power in storms. Statewide, 10 percent of households went at least 24 hours without power in 2024, and the region has logged 61 winter storms and 346 damaging wind events over the past ten years. A furnace that comes back on by itself when power returns matters here. If the furnace you're installing is a non-weatherized gas model built after November 2015, federal rule sets its minimum efficiency at 80 percent AFUE, so that much is decided before you pick a brand.

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

- What size furnace does my house need?
- The right size depends on your home's square footage, insulation, window count, and layout, not just one number you can look up. A furnace that's too big will short cycle and wear out faster. One that's too small will run constantly and still leave rooms cold when it's 23 degrees outside. A contractor sizes it with a load calculation that looks at your actual house, not a rule of thumb.
- How do I know it's time to replace my furnace?
- If it needs frequent repairs or can't keep the house warm anymore, it's time to start looking. Watch for rising gas bills with no other explanation, rooms that heat unevenly, or a furnace that runs longer and longer to hit the same temperature. Homes here need heat from October through May, so a furnace on its way out gets tested for eight months straight, not just a few cold weeks. A furnace that fails on a night near 23 degrees leaves you without heat fast, so it's worth replacing on your schedule instead of its.
- Is a high-efficiency furnace worth it?
- It depends on how long you plan to stay in the home and what you're replacing. Every new non-weatherized gas furnace sold today has to hit at least 80 percent AFUE by law, so even a standard model is fairly efficient. High-efficiency models go higher than that, which matters more here since furnaces run eight months a year instead of just a few. A contractor can walk through the actual models and what each one means for your specific furnace and duct system.
