Ten months of heating in Nez Perce County
Your furnace here runs from September through June, ten months a year. Winter nights average 26°F from December through February, so it's lighting the burner on and off most days through most of the year, not just a few cold weeks.
Any gas furnace installed here has to meet 80 percent AFUE, the federal minimum for non-weatherized models built since November 2015. Power outages happen in this state too, so it's worth asking your contractor how the new furnace starts back up once power returns.

Idaho requires HVAC contractors to hold a state license.
The license is issued to the contractor, not to this specific furnace job. Idaho's HVAC Board tests and records the person or company before they take on your work, so the credential follows them from one house to the next.
For the installation itself, that license is what stands behind the work. Beyond it, most cities and counties in Idaho also require a permit for a furnace replacement, with an inspection once the work is done, and that inspection checks the installation itself, including the gas connection, separately from the contractor's license. In Nez Perce County, just over half of homes heat with gas, so a furnace installation here is often gas work, and that permit and inspection are what covers the connection.

- What size furnace does my house need?
- There is no single answer without a load calculation done for your house. A contractor works through the square footage, the insulation, the windows, and how the place is laid out, then sizes the furnace to match. Guessing based on square footage alone gets it wrong both ways, and either way costs you. Too big and it short cycles, heating fast then shutting off before it evens out the house. Too small and it runs constantly and still cannot keep up when it drops to 26 degrees on a winter night.
- How do I know it's time to replace my furnace?
- Watch for repairs that keep coming back, a furnace that is getting old, and rooms that stay cold no matter what you do. Furnaces here run September through June, ten months of the year, so wear adds up faster than it does somewhere with a short winter. If a technician has been out more than once this season for the same kind of problem, that is a sign the furnace is wearing out rather than having a bad week. A sharp rise in your gas bill with no other explanation points the same direction.
- Is a high-efficiency furnace worth it?
- It depends on how long you plan to stay in the house and what furnace you have now. Furnaces made since late 2015 already have to reach 80 percent AFUE at minimum, so the real choice is between that baseline and a high-efficiency model that wastes less gas out the vent. With heat needed here ten months a year, more than half the homes in the county running on gas, and winter lows averaging 26 degrees, a furnace that wastes less fuel is doing more work here than it would somewhere milder. A contractor can price both options against what your house actually needs.
