Why heat pumps fit this area
A heat pump is an air conditioner that can run in reverse to heat. Southwest Utah's winters are mild enough, with nights that sometimes drop below freezing, that a heat pump with backup heat handles them.
In summer it works like any AC, and its coils face the same red dust, so the care is similar: keep the coil clean and the filter fresh. The U.S. Department of Energy explains how heat pumps work.
Rebates: what to check first
Rocky Mountain Power's Wattsmart program has offered rebates on air source heat pumps for existing homes, with amounts that depend on the efficiency tier and on what the heat pump replaces.
Rocky Mountain Power's own site says up to $1,800, and the utility has proposed changes to its incentives in 2026, so confirm current terms on its Wattsmart page.
You must be a Rocky Mountain Power customer, and some cities here, including St. George and Hurricane, run their own utilities, so check your bill.
There is no federal tax credit for a heat pump installed in 2026, because Section 25C ended after December 31, 2025.
What a good installation includes
- A load calculation that sizes the system to your home.
- Equipment chosen to match that load, with cold weather performance in mind.
- A look at the ducts, since heat pumps often need different airflow from an AC only system.
- Refrigerant charge verified, not guessed.
- Defrost operation and backup heat tested.
- The permit and the paperwork your rebate needs.

Heat pump or AC plus furnace?
For many homes in Washington and St. George the choice comes down to a few facts:
| Question | Heat pump | AC plus gas furnace |
|---|---|---|
| Cools in summer | Yes | Yes |
| Heats in winter | Yes, with backup heat for the coldest nights | Yes, very strongly |
| Equipment to maintain | One system, serviced in spring and fall | Two systems |
| Fits mild winters | Very well | Works, though the furnace runs few hours |
| Rebate options | Utility rebates may apply | Fewer for the AC alone |
If your furnace is newer and works well, keeping it and replacing only the AC is sometimes the better value. We tell you which fits your house.
Ducts in attic homes
Many homes here have ducts in a very hot attic. A heat pump relies on good airflow in both seasons, so we check the ducts during the estimate and tell you whether sealing, insulation or a larger return would help before you spend on equipment.
