Richfield asks a furnace to run ten months a year
Winter nights here average 17°F, and homes need heat from September through June. That is ten months of the year your furnace has to work, with only a short break in summer.
A new furnace installed here has to be built for that. Any non-weatherized gas furnace made since November 2015 has to reach at least 80 percent AFUE, and most of Sevier County heats with gas. With winters this long, the furnace you install now is one you will run almost every month you live here.

Utah requires HVAC contractors to hold a state license.
The Division of Professional Licensing tests and records the contractor, not the job itself. The license tells you the person doing the work has been vetted by the state. Utah does carve out an exception. Work under $7,000 does not need a licensed contractor. A furnace installation runs well past that line, so this is a licensed job.
A furnace burns gas, and the connection to the gas line is the part that has to be right. That check does not come from the license. It comes from the local building office, which in most cities and counties in Utah requires a permit for a furnace replacement and an inspection once it is done. Most homes in Sevier County heat with gas, so that inspection is a routine step here.

- What size furnace does my house need?
- The right size depends on your house, not a rule of thumb. A contractor works this out with a load calculation that looks at your square footage, insulation, window count, and ceiling height, along with how cold it gets here. With winter nights averaging 17°F, getting the size right matters more than it would somewhere milder. Too small and it runs constantly without keeping up. Too big and it cycles on and off, which wears out parts faster and leaves rooms uneven.
- How do I know it's time to replace my furnace?
- Watch for uneven heat, rooms that never get comfortable, or a furnace that needs repairs more than once a season. Homes here need heat from September through June, so a furnace that struggles is a ten month a year problem, not an occasional one. Rising gas bills with no other explanation or a cracked heat exchanger are also signs a contractor should look at. If you're already calling for repairs every winter, replacement is worth pricing out against another fix.
- Is a high-efficiency furnace worth it?
- It depends on what you're comparing it to. Any non-weatherized gas furnace sold new today has to reach at least 80.0 percent AFUE, so the real choice is between that baseline and a high-efficiency model that runs higher than it. With most homes here heating with gas across a heating season that runs September through June, the furnace runs a lot, and efficiency has more chance to matter than it would in a place with a short heating season. A contractor can price out both options for your house and tell you what each would actually mean for your setup.
