Heat pumps in St. George
A climate that spends most of its energy on cooling is a good climate for a heat pump. Here is the local detail that decides whether it is right for your house.
- We book the appointment

- You contract directly with them
Why the argument is different here
Most of the national debate about heat pumps is really a debate about cold weather — how they behave at 5°F, when the backup heat kicks in, what happens to the electricity bill in January. That debate matters in Logan. It matters much less in a county whose cooling design temperature is 109°F and whose heating season is short and mild by Utah standards.
A heat pump is an air conditioner that can also run backwards. In a place where the air conditioning side does the overwhelming majority of the work, you are buying the part that matters most anyway, and getting heating as a second use of the same equipment. That is a genuinely different value calculation from the one made along the Wasatch Front.
The sizing logic on the cooling side is identical to a straight AC replacement, and it is just as easy to get wrong.
Dual fuel, and when it makes sense
A dual fuel setup pairs a heat pump with a gas furnace and hands heating over to the furnace when the outdoor temperature drops past a set point. If you already have a gas furnace in reasonable condition and you are replacing the air conditioner, this is the configuration worth asking about, because it uses equipment you already own. Whether it pencils depends on your gas and electric rates and on which utility serves you — which is not the same answer for every address in this county.
The rebate detail that catches people out
Dixie Power's residential heat pump rebate is a new construction programme. Homeowners regularly assume it applies to replacing a system in an existing house, and it does not. If a salesperson is folding that rebate into the numbers on a changeout, ask them to show you the programme terms.
The programme also specifies a minimum two-ton electric heat pump with electric backup or dual fuel, and rebate applications run on a 60-day-after-install window. Terms are on dixiepower.com. Rocky Mountain Power customers are on an entirely separate programme — Wattsmart Homes — so check which utility bills you before assuming anything.
We do not administer or guarantee utility rebates and we quote no figures for them. Confirm directly with your utility.
How to check the contractor's licence yourself
Utah licenses heating and cooling contractors through the Department of Commerce, Division of Professional Licensing. The classification to look for is H100 — HVAC. DOPL's current contractor classification list no longer carries the older S350 HVAC specialty; new HVAC applications moved to H100, with the updated application requirements taking effect 20 April 2026.
Under the current requirements an H100 applicant has to complete a 25-hour pre-licensure course, pass the H100 written trade exam, and document 4,000 hours of qualified HVAC employment within the past five years using W-2s, K-1s or tax returns. DOPL also sets general liability insurance minimums for the classification, and a fingerprint-based background check requirement begins 1 January 2027.
You do not have to take anyone's word for it, including ours. Utah publishes a free licence lookup: secure.utah.gov/llv. Search the business name before work starts.
