Eight months of heat, nights near 21°F
Kiryas Joel needs a working furnace from October through May. That is eight months a year, and winter nights average 21°F. A furnace here does not get much time to rest between seasons.
Almost half of homes in the area heat with gas. Any new gas furnace has to reach at least 80 percent AFUE, the federal minimum since November 2015. Power is worth planning around too. Across New York, 11 percent of households lost power for at least a day in 2024, and this region has logged 20 winter storms and 155 damaging wind events over the past ten years.

- What size furnace does my house need?
- The right size depends on your square footage, your insulation, your ceiling height, and how many windows you have facing north. A furnace that's too big will short cycle and wear out faster. One that's too small will run constantly and still leave you cold on nights that drop to 21°F. A contractor will do a load calculation on your actual house rather than guess from square footage alone, and that's the only way to get the number right.
- How do I know it's time to replace my furnace?
- Watch for rising repair calls, uneven heat between rooms, and a furnace that runs longer than it used to just to hold the same temperature. Heat is needed here from October through May, so a furnace on its last legs gets tested on the coldest nights, not the mild ones. A furnace that cycles on and off rapidly or won't hold a pilot is also telling you something. If yours is old and the repairs keep coming, a new one will likely cost less over time than keeping the current one alive.
- Is a high-efficiency furnace worth it?
- It depends on how long you'll keep the house and how much you run the furnace. Every non-weatherized gas furnace sold since November 2015 has to hit at least 80 percent AFUE, so even a standard model isn't wasteful anymore. A high-efficiency furnace burns less gas to make the same heat, and with heat needed here from October through May, that difference adds up over the life of the unit. Whether the higher upfront cost pencils out for your house is something a contractor can walk through with real numbers.
