A Bronx furnace runs seven months a year
Winter nights in the Bronx average 28°F from December through February, and homes here need heat from October through April. That's seven months of the burner cycling on and off to hold the house at temperature.
A new gas furnace installed now has to meet the federal minimum of 80 percent AFUE if it's a non-weatherized unit, and most homes here heat with gas. The Bronx has also logged 16 winter storms and 20 damaging wind events over the past ten years, and statewide, 11 percent of households went at least 24 hours without power in 2024. A furnace going in now is also part of how the house holds up when the power does too.

A high-efficiency gas furnace would save about $110 a year to run in Bronx County compared with a gas furnace.

- What size furnace does my house need?
- The right size depends on your square footage, your insulation, your windows, and your home's layout, so there is no number that works for every house. A contractor sizes it with a load calculation that looks at all of that together. Going too big wastes fuel and cycles the furnace on and off more than it should. Too small, and it will run constantly through the worst of a Bronx winter and still fall behind when the temperature drops toward that 28°F overnight average.
- How do I know it's time to replace my furnace?
- Age is the first sign, and a furnace running past its expected lifespan is more likely to break down when you need it most. Rising bills, a system that short cycles, uneven heat between rooms, or repairs that keep coming back are other signs the furnace is wearing out rather than just having a bad week. With heat needed here from October through April, a furnace on its last legs does not get much of a season to rest and recover. A contractor can tell you whether what you are seeing is normal wear or the start of the end.
- Is a high-efficiency furnace worth it?
- It depends on how long you plan to stay in the house and what your furnace is running on now. Every non-weatherized gas furnace made since November 2015 already has to hit at least 80 percent AFUE, so the real choice is whether to go higher than that baseline. A high-efficiency model burns less gas to make the same heat, and with over half of homes here heating with gas and needing it for 7 months a year, that difference shows up on more bills than in places with shorter winters. A contractor can walk you through the actual models and what each one would cost for your house.
