Ephraim asks a furnace to run almost year round

Homes here need heat from September through June, ten months of the year. Winter nights average 16°F, cold enough that a furnace runs long hours, night after night, to hold a house steady.

Most homes here heat with gas, and any new non-weatherized gas furnace has to reach at least 80 percent AFUE under the federal minimum. With a season this long, the furnace installed now is the one that carries most of the year.

Utah requires HVAC contractors to hold a state license.

Utah licenses HVAC contractors through the Division of Professional Licensing. The state has tested this contractor and keeps a record of them. That license covers the contractor, not this particular job. One exception applies here. Work under $7,000 does not need a licensed contractor in Utah, though a full furnace installation will almost always run past that.

For this job, the license is what stands behind the contractor doing the work. It is not the only check on this installation. Most cities and counties require a permit from the local building office before a furnace goes in, with an inspection once the work is done. That inspection is where the gas connection gets checked, and that connection is the part of this job that can actually hurt someone. Most homes in Sanpete County heat with gas, so that inspection is not paperwork. It is where someone apart from the contractor looks at the work.

What size furnace does my house need?
The right size depends on your square footage, your insulation, your windows, and your ceiling height, so there is no number that works for every house. A furnace that is too big cycles on and off too fast and never runs long enough to heat evenly. One that is too small runs constantly and still leaves rooms cold on a 16°F night. A contractor works this out with a load calculation on your actual house, not a guess based on square footage alone.
How do I know it's time to replace my furnace?
Watch for uneven heat, a furnace that runs longer than it used to, or repairs that keep coming back. Heat matters here nearly year round, with homes needing it from September through June, so a furnace that struggles now will only get worse once the cold nights set in. Age matters too. If yours is old enough that parts are getting harder to find, or the repair bill is climbing close to what a new unit costs, replacing it stops being a question of if.
Is a high-efficiency furnace worth it?
It depends on how long you plan to stay in the house and how much you run the furnace. With heat needed 10 months a year here and winter nights averaging 16°F, a furnace in this area runs far more than one in a milder climate, so efficiency gains add up faster. Any new non-weatherized gas furnace has to meet at least 80.0 percent AFUE by law, and higher-efficiency models go well past that. A contractor can walk you through the actual models and what each one means for your house.
