What a system in Salt Lake County has to handle
Your furnace here runs October through May, eight months a year, with winter nights averaging 22°F in December through February. That is a long, cold season, and most homes in the county lean on gas to get through it. Your air conditioner has a shorter job, three months, June through August, with afternoons averaging 83°F.
A new system has to be sized for both ends of that range, not just the season you are replacing it in. Federal rules set a minimum efficiency for new central air conditioners and furnaces, so whatever goes in will meet that floor at least. Salt Lake County has also seen 91 winter storms and 194 damaging wind events over the past ten years, and 7% of Utah households lost power for at least 24 hours in 2024. A furnace with a standing pilot still lights without power. One with electronic ignition will not, though most central air conditioners and furnaces come back on by themselves once power is restored.

Utah requires HVAC contractors to hold a state license.
Utah licenses HVAC contractors through the Division of Professional Licensing. The license belongs to the contractor, not to any one job, so the state has a record of who this contractor is before your installation ever starts. Work under $7,000 doesn't need a licensed contractor, but a full heating and cooling system installation runs well past that line, so the license applies here.
The license covers the contractor, not the work itself. What backs up this particular job is the permit. In most Utah cities and counties, installing a new furnace, air conditioner or heat pump needs a permit from the local building office, and the finished work gets inspected once it's done. That inspection is what catches a bad gas connection or a flue that isn't vented right. The license tells you who is allowed to do the work. The permit and inspection tell you whether this installation was done right.

- When should I replace my HVAC system?
- Replace it when it's struggling to keep up or the repairs keep coming back, rather than waiting for it to fail outright. Watch for rising utility bills, rooms that never quite reach temperature, and a repair technician who's been out more than once for the same problem. Homes here need heat or cooling 11 months of the year, so a system that's already straining doesn't get much of a break. If your furnace is getting old and winter is coming, that's a better time to replace it than the night it quits at 22 degrees.
- Should I replace my furnace and air conditioner at the same time?
- If both are old, yes. A furnace and air conditioner installed together are matched to work as one system, and pairing a new unit with an old one can mean the new one never runs at its best. It also means one visit and one inspection instead of two, spaced out over however many years until the second unit fails. If only one has actually failed, a contractor can tell you whether the other has enough life left to wait.
- What happens during an HVAC installation?
- A contractor removes the old furnace and air conditioner and puts in the new ones, then connects them to your existing ductwork, gas line, and electrical. They check the ducts for leaks or damage and make sure the new equipment is sized right for the house, since a unit that's too big or too small won't heat or cool evenly. Once it's running, they test it and walk through what it needs going forward. In most cities and counties here, this work needs a permit and an inspection when it's done, so ask the contractor how that's handled before work starts.
