Eight months of heating in Niagara Falls
Winter nights here average 21°F, and homes need heat from October through May. That's eight months a year the furnace has to work, not just the coldest stretch of winter.
Most homes in Niagara Falls heat with gas. Any non-weatherized gas furnace built after November 2015 has to reach at least 80 percent AFUE, so that's the floor for a new unit, not a selling point. Winter storms are common here too, and a furnace that starts reliably matters when the power and the weather don't cooperate at the same time.

- What size furnace does my house need?
- It depends on your square footage, your insulation, your windows, and your ceiling height, so there's no single number that fits every home. A contractor works this out with a load calculation, not a chart based on house size alone. Guessing high seems safe but isn't. A furnace that's too big cycles on and off fast, which wears out parts sooner and leaves rooms uneven, and with winter lows here averaging 21°F, getting the size right matters more than it would somewhere milder.
- How do I know it's time to replace my furnace?
- Watch for rising repair calls, uneven heat between rooms, and a furnace that struggles to keep up on the coldest nights. If a technician tells you the heat exchanger is cracked, that's a straight replace, not a repair. Homes here need heat from October through May, eight months of the year, so a furnace that's wearing out shows it fast. If yours is short-cycling or running longer to hit the same temperature, have it looked at before the cold months make the problem worse.
- Is a high-efficiency furnace worth it?
- It depends on how long you plan to stay in the house and what your current furnace is costing you to run. Furnaces built since November 2015 already have to hit 80.0 percent AFUE at minimum, so even a standard model isn't wasting as much fuel as an older one might. A high-efficiency model burns less gas to make the same heat, and with homes here needing heat eight months of the year, that difference adds up. A contractor can run the numbers on your specific furnace and usage to see what makes sense for your house.
