What Asheville winters ask of a new furnace

Your furnace here works October through April, seven months of the year. Winter nights average 28°F, so on most of them the burner is cycling on and off to keep the house warm. A furnace has to hold up over that whole stretch, not just the coldest weeks.

Most homes in this area heat with electricity, and the power here does go out. In 2024, a quarter of North Carolina households lost power for 24 hours or more, and this area has seen 8 winter storms and 55 damaging wind events over the past ten years. Any non-weatherized gas furnace installed now has to meet 80.0 percent AFUE. That much is set by federal rule, whichever furnace you choose.

North Carolina requires HVAC contractors to hold a state license.

The license is tied to the contractor, not to this furnace job specifically. It means the person or business doing the work was tested by the State Board of Examiners of Plumbing, Heating and Fire Sprinkler Contractors and is on record with them, but the board does not inspect the work once it is in.

That part usually falls to the local building office. In most cities and counties, replacing a furnace needs a permit before the work starts and an inspection once it is done, and that inspection is what checks the gas connections and venting on this particular job.

What size furnace does my house need?
The right size comes from a load calculation, not the size of the furnace you have now. A contractor measures your square footage, your insulation, your windows, and how the house holds heat, then runs those numbers to find the output you need. 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 on a 28°F night. There's no shortcut that replaces this calculation for your specific house.
How do I know it's time to replace my furnace?
Watch for repairs that keep coming back, a cracked heat exchanger, or a furnace that can't keep the house warm through a cold night anymore. Age matters too. An older furnace that needs frequent repairs often costs more to keep fixing than to replace. If yours is getting up there in years and the repair calls keep coming, that's usually the sign. Homes here need heat from October through April, so a furnace on its last leg tends to show its worst side right when you need it most.
Is a high-efficiency furnace worth it?
It depends on how much heat your house uses and how long you plan to stay in it. Any non-weatherized gas furnace built after November 19, 2015 already has to reach at least 80 percent AFUE, so the real question is whether it's worth paying more for a furnace that clears that minimum by a wide margin. With heat needed here seven months a year and winter nights averaging 28°F, a furnace that runs often has more chances to make back the difference in fuel use over its life. A contractor can walk through the numbers for your specific house and heating habits.
