Heat pumps in our climate

The most efficient HVAC technology you can install, and our climate is ideal for it.

A modern heat pump can cut a Washington County energy bill by 30–60% versus an electric furnace. We've been installing and servicing heat pumps in the St. George area for over three decades, long before they were fashionable.

Southern Utah's mild winters are essentially a best-case scenario for heat pump performance. Where heat pumps in Minnesota struggle below 0°F, ours rarely see anything colder than the high teens, and only for a few hours per year. A properly sized variable-speed heat pump from a quality manufacturer will deliver 95%+ of its rated capacity all winter long here, with a coefficient of performance (COP) that translates to roughly 2–4x the heat per kilowatt-hour of an electric furnace.

We've been installing heat pumps in the St. George area for over 30 years, long before they became a common choice here. That experience matters: heat pump installs are less forgiving of bad commissioning than a traditional AC and furnace, and the difference between a textbook install and a sloppy one shows up in your electric bill every month for the next 15 years.

Utility rebates

Ask us about utility rebates.

Depending on who provides your gas and power, a new system may qualify for a utility rebate. For homes with natural gas service, Enbridge Gas's ThermWise program offers rebates on qualifying dual-fuel heat pump systems, and some local power providers run programs of their own.

Programs, amounts, and equipment requirements change, and not every address is served by the same utility. When we write your quote, we check what your home qualifies for and provide the itemized invoice and equipment details the application asks for.

Heat pump FAQ

Do heat pumps actually work in Southern Utah?
They work exceptionally well here. Heat pumps lose efficiency below about 25–30°F, and our winter design temperature in the St. George area is around 28°F, well within the range where modern variable-speed heat pumps deliver excellent performance. Up in Hurricane and Toquerville where mornings can dip lower, we spec cold-climate heat pumps or pair them with a small auxiliary heat strip for the handful of cold nights per year.
Are there rebates for a new heat pump?
It depends on who provides your gas and power. For homes with natural gas service, Enbridge Gas's ThermWise program offers rebates on qualifying dual-fuel heat pump systems, and some local power providers run programs of their own. Amounts and equipment requirements change, so we check what your address qualifies for when we write your quote.
Should I replace my furnace and AC with a heat pump?
Often, yes. A modern heat pump replaces both your AC and your furnace with a single piece of outdoor equipment that's typically 2–4x more efficient than electric resistance heat and competitive with high-efficiency gas in our climate. Depending on your utility, a rebate can help the math too. We'll run the numbers with your specific energy rates before recommending.
What's the difference between a ducted heat pump and a mini-split?
A ducted heat pump uses your existing ductwork (or new ducts) to distribute conditioned air, the same delivery method as a traditional AC and furnace. A mini-split (ductless) heat pump has individual indoor heads in each zone, no ductwork required. Mini-splits shine in additions, casitas, basements, or homes where running ducts would be invasive. Both can be excellent choices.
How long do heat pumps last in this climate?
Properly installed and maintained heat pumps run 12–18 years in Southern Utah. The compressor cycles harder than a furnace because it runs both summer and winter, but modern variable-speed compressors are dramatically more durable than the older single-stage units. Annual maintenance (coil cleanings, refrigerant checks, defrost board testing) extends life significantly.
Will a heat pump make my home feel as warm as my furnace did?
It will heat your home to the same setpoint, but the supply air temperature is typically 90–105°F instead of a furnace's 130–140°F. People sometimes describe heat pump air as feeling 'cooler' even though the room is the same temperature. The fix is sizing the system correctly and using slightly higher airflow. Neither costs anything extra, and both should be standard practice.
