Eight months of heat, and winter nights near 21 degrees
Gooding needs a furnace from October through May. That is eight months of the year the burner is doing real work, and on winter nights that average 21°F, it is doing that work hard.
Most homes here run on electric heat, and the power does not always stay on. Idaho saw 11% of households lose power for at least 24 hours in 2024, and this area has logged 12 winter storms and 16 damaging wind events over the past ten years. A new furnace should be able to come back on by itself once power returns. If you're installing a gas furnace, federal rules set the floor at 80 percent AFUE for standard, non-weatherized models built since November 2015, so any furnace going in now has to clear that mark.

Idaho requires HVAC contractors to hold a state license.
Idaho tests contractors before licensing them, and the HVAC Board keeps that record on file. The license belongs to the contractor, not to this one job, so it tells you the business behind the work has met the state's standard, not that this particular installation gets checked as it happens.
That check comes from the permit. A furnace installation in most Idaho cities and counties needs a permit from the local building office, and the finished work gets inspected before it's signed off. That inspection is separate from the license and happens on this job specifically, on top of whatever the license already covers.

- What size furnace does my house need?
- The right size comes from a load calculation, not the square footage of your house alone. A contractor measures your insulation, your windows, your ceiling height, and how the place is laid out, then runs those numbers to find the heat loss on a cold night. Here that matters more than in most places, since winter lows average 21°F and the furnace has to keep up from October through May. 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.
- How do I know it's time to replace my furnace?
- Watch how your furnace is running, not just how old it is. Rooms that used to heat evenly and no longer do, a furnace that runs longer to reach the same temperature, or repairs that keep coming back are all signs it's falling behind. With heat needed here from October through May, a struggling furnace has little time each year to rest and recover. If yours is showing these signs before winter sets in, replacing it before a breakdown is worth considering.
- Is a high-efficiency furnace worth it?
- It depends on how much heat your house needs and how long you'll be running it. Every non-weatherized gas furnace sold since November 2015 has to reach at least 80 percent AFUE, so even a standard model isn't wasteful. A high-efficiency furnace goes above that minimum, which means less heat lost out the flue. With homes here needing heat for 8 months of the year, a furnace running that long has more chances for the difference in efficiency to add up. A contractor can walk you through the options for your house and price out what each one involves.
