Delta asks a furnace to run eight months a year
Heat goes on in October here and stays on into May. That is eight months of the year your furnace has to work, with winter nights averaging 20°F. A new furnace installed here needs to handle that stretch without strain, not just the coldest week of it.
Most homes in the area heat with gas, and any new gas furnace has to meet the federal minimum of 80 percent AFUE. Power outages are worth planning for too. Across Utah, 7 percent of households lost power for 24 hours or more in 2024, and the last ten years brought 32 winter storms and 39 damaging wind events to this area. A furnace that starts back up on its own once power returns matters when a storm knocks it out overnight.

Utah requires HVAC contractors to hold a state license.
The license is issued to the contractor by the Division of Professional Licensing, and it covers that contractor, not the individual job. Utah does carve out an exception. Work under $7,000 does not need a licensed contractor. A furnace installation is unlikely to fall under that line, so the contractor doing this job should hold the state license.
In most cities and counties, a furnace installation also needs a permit from the local building office, with an inspection once the work is done. That permit and inspection stand apart from the state license. Most homes in Millard County heat with gas, and this installation is one more of them.

- What size furnace does my house need?
- The right size depends on your house, not a rule of thumb like square footage alone. A contractor works this out with a load calculation that accounts for your insulation, your windows, your ceiling height, and how the house holds heat through a night that drops to 20°F. A furnace that is too big cycles on and off too often and never runs long enough to heat evenly. One that is too small runs constantly and still falls behind when winter settles in from October through May. Ask whoever quotes the job to walk you through the calculation, not just hand you a number.
- How do I know it's time to replace my furnace?
- Watch for uneven heat, rooms that stay cold, a furnace that cycles on and off more than it used to, or a rise in gas use without a reason. Repairs that keep coming back are another sign, especially once the furnace is old enough that parts are harder to find. Age matters here more than in places with mild winters, since your furnace runs eight months a year, October through May. A furnace that struggles through that stretch is worth having looked at before the coldest nights hit.
- Is a high-efficiency furnace worth it?
- It depends on how much your furnace runs and what you are paying for gas now. In Delta, furnaces run eight months a year, so the efficiency rating matters more here than somewhere with a short winter. Every furnace made since November 2015 has to hit at least 80 percent AFUE, so the real choice is between that baseline and the higher-efficiency models above it. A contractor can walk you through the difference in output for your specific house, since the right call depends on your gas use and how the furnace will be installed.
