Eight months of heat, and nights near 19 degrees

Brigham City needs a working furnace from October through May. That's eight months out of the year, not just a few cold weeks. Winter nights average 19°F here, which means the furnace runs long hours, night after night, to keep up.

Most homes here heat with gas, and any new non-weatherized gas furnace built since November 2015 has to reach at least 80 percent AFUE by federal rule. That's the floor, not a feature. With this many storms and outages on record in Utah, a furnace that starts reliably every time matters as much as one that runs efficiently once it's going.

Utah requires HVAC contractors to hold a state license.

The state tested this contractor and keeps a record of the license under the Division of Professional Licensing. That license belongs to the contractor, not to any single job, so it carries over from one house to the next. Utah does carve out one exception. Work under $7,000 does not need a licensed contractor. A furnace installation almost always runs past that number, so the license requirement applies here.

Beyond the license, the local building office is the other check on this job. Most cities and counties require a permit for a furnace replacement and an inspection once the work is done. That inspection is what catches a bad gas connection, and a bad gas connection is the part of this job that can actually hurt someone. Close to eight in ten homes in Box Elder County heat with gas, so that inspection step is not a formality here.

What size furnace does my house need?
The right size depends on your home's square footage, insulation, window count, and layout, so there's no single number that works for every house. A furnace that's too big will cycle on and off too often and never run long enough to heat evenly. One that's too small will run constantly and still leave you cold on the coldest nights here. A contractor will do a load calculation on your actual house before recommending a size, and that's worth insisting on rather than going by the size of the unit you're replacing.
How do I know it's time to replace my furnace?
If your furnace is struggling to keep up on the coldest nights, cycling on and off more than it used to, or needing repairs more often, it's telling you something. Furnaces here run from October through May, eight months of the year, so a unit that's wearing out gets pushed hard for most of the year. Rising gas bills without a clear reason, uneven heat between rooms, and a furnace that's older and needs frequent service calls are all signs worth having looked at. A contractor can tell you whether a repair still makes sense or whether you're better off replacing it.
Is a high-efficiency furnace worth it?
It depends on how much you heat your home and what you're comparing it to. With winter lows here averaging 19°F and heat needed eight months a year, a furnace runs a lot in this area, so efficiency has more chance to matter than it would somewhere with a short, mild winter. Furnaces made since November 2015 are already required to hit at least 80 percent AFUE, so the real question is whether a higher-efficiency model saves enough over that baseline to be worth the difference in upfront cost. A contractor can walk you through the options for your house and let you weigh that against what each unit costs installed.
