What Spring Valley winters ask of a new furnace
Spring Valley homes need heat from October through May. That is 8 months a year the furnace has to work, with winter nights averaging 23°F. A new furnace here needs to be sized for that long a stretch, not just the coldest nights in it.
Most homes in the area heat with gas, and any non-weatherized gas furnace built after November 19, 2015 has to reach at least 80.0 percent AFUE by federal rule. The area has also seen 14 winter storms and 42 damaging wind events over the past ten years, and statewide, 11% of households lost power for a full day or more in 2024. A furnace with no power can't run no matter how cold it gets outside, which is worth factoring into how a new one is installed.

A high-efficiency gas furnace would save about $120 a year to run in Rockland County compared with a gas furnace.

- What size furnace does my house need?
- The right size depends on your home's square footage, ceiling height, insulation, window count, and layout, so there is no single number that fits every house. A furnace that's too big cycles on and off too often and wears out faster. One that's too small runs constantly and still can't keep up on a 23°F night. A contractor will do a load calculation on your specific house and give you a number based on it, not a guess.
- How do I know it's time to replace my furnace?
- If your furnace is struggling to keep the house warm, cycling on and off more than it used to, or needing repairs every winter, it's time to start looking at replacement. Age matters too. Furnaces here run from October through May, eight months a year, so they log a lot of hours and wear out faster than in milder climates. A furnace that can't recover heat quickly on a night near 23°F is telling you something. If a repair bill is creeping close to what a new unit would cost, replacement usually makes more sense than another patch.
- Is a high-efficiency furnace worth it?
- For a house that needs heat eight months a year, efficiency matters more here than it would somewhere with a short winter. Every non-weatherized gas furnace made since November 2015 has to reach at least 80 percent AFUE, so even a standard new furnace already meets that mark. A high-efficiency model goes beyond that minimum, wasting less gas turning it into heat, which matters most in a place where the furnace runs from October through May. Since most homes here heat with gas, that difference adds up over eight months in a way it wouldn't in a climate with a shorter heating season.
