Eight months of heat, and nights that drop to 25°F
Payette County homes run the furnace from October through May. That's eight months a year. On the coldest nights the average low sits at 25°F, and the furnace has to hold the house steady for hours at a time, not just take the edge off.
Any gas furnace installed new now has to reach at least 80 percent AFUE. That's the federal minimum, and it applies no matter who installs it.

Idaho requires HVAC contractors to hold a state license.
The HVAC Board tested this contractor and holds their license on record, but that license covers the business, not this particular furnace once it's in your house.
In most cities and counties, installing a furnace needs a permit from the local building office, with an inspection once the work is done. That inspection is what catches a bad gas connection or a venting mistake, the part of this job that matters most if it's done wrong. The license tells you the contractor was tested. The permit and inspection tell you this furnace was checked.

- What size furnace does my house need?
- The right size depends on your square footage, insulation, window count, and ceiling height, so there is no single number that fits every house. A contractor works this out with a load calculation, not a chart based on home size alone. Getting it right matters here, since these furnaces run from October through May. Too big and it cycles on and off without evenly heating the house. Too small and it will struggle on the coldest nights, when lows average 25°F.
- How do I know it's time to replace my furnace?
- Watch for repairs that keep coming back, uneven heat between rooms, or a furnace that runs longer than it used to just to hold the same temperature. An aging furnace is more likely to fail on the night you need it most, and in this area that means eight months of the year depending on it, with winter lows around 25°F. If your gas furnace was made after November 2015, it already meets the 80 percent AFUE minimum, so an older model may be running well below that.
- Is a high-efficiency furnace worth it?
- It depends on how much you run your furnace and what you're comparing it to. Homes here need heat eight months a year, October through May, so a more efficient furnace has a long stretch of cold weather to make a difference. High-efficiency models also vent differently and often need a condensate line, which can affect installation. A contractor can walk through the options and price the job for your house, since installation costs vary.
