Heat Pump Repair in Las Vegas
Short answer: Most Las Vegas heat pump calls trace to a defrost control, reversing valve, capacitor, or control wiring fault. Colton tests heating and cooling mode where weather allows and explains the fault before quoting. See heat pump not heating and heat pump vs furnace.

Heat pumps handle most Las Vegas winters without a gas furnace, then carry the entire cooling load in July. They have to be set up for both, or the backup heat runs all night.
A heat pump is an air conditioner that can run backwards. If the cooling side is strong and the heating side is weak, the problem is often defrost, the reversing valve, or controls that were never set up for a heat pump. We diagnose both modes before anyone talks replacement. See heat pump defrost mode.
On replacements we talk through strip heat, dual fuel, and what a higher SEER2 number is actually worth on a 115° design day — without inventing rebate amounts or brand tiers we cannot verify.
How we diagnose a heat pump
- Confirm the operating mode and control wiring. The tech checks heat pump versus auxiliary or emergency heat, and the staging.
- Watch a heating cycle and a defrost cycle. We check the defrost control, sensors and reversing valve.
- Test the electrical side. Capacitor, contactor, outdoor fan motor, compressor amp draw, and the heat strips and sequencers.
- Check the refrigerant charge with gauges against the manufacturer's data, and look for leaks if it's low.
- Check airflow. Blower and indoor coil, and static pressure where the airflow seems off.
- Report the findings with the repair option first.

Common heat-pump calls
- Outdoor unit freezing in winter
- Emergency heat that never turns off
- Cooling that is fine and heating that is not
- A replacement conversation for an aging heat pump
What we check
- Defrost cycle and reversing valve
- Backup heat staging
- Charge and airflow in both modes
- Whether repair or a matched heat-pump replacement makes sense
A minor failure stays a repair. See heating repair, furnace repair, and AC repair Las Vegas when the symptom is broader.
Heat pump service
A heat pump service visit is a look at the parts that let one outdoor unit both heat and cool your home. Here is what our tech checks:
- Defrost: in heating mode, frost builds on the outdoor coil. The tech confirms the system notices it and clears it, then goes back to heating.
- Reversing valve: this valve switches the direction refrigerant flows. The tech confirms it shifts fully between heating and cooling and is not stuck partway or leaking through.
- Backup heat: most heat pumps here have electric heat strips for the coldest mornings. The tech confirms they come on only when they should and shut off when the heat pump catches up.
- Refrigerant: the tech reads pressures and temperatures with gauges and compares them to the manufacturer's numbers. A low reading means a leak somewhere, and the tech looks for it.
You get a plain report of what was checked and what is wearing out.
Heat pump replacement
We start with repair. Many heat pumps that seem worn out have one failed part, like a capacitor, contactor, defrost board or fan motor, and fixing it gets the system running again. Replacement comes up when the compressor has failed, when the coil is leaking badly, or when repeat repairs on an old system stop making sense. When that happens, we explain what we found and why, and you decide. If you do replace, we size the new heat pump for your house and for Las Vegas summers, since the same unit does all your cooling too.

Heat pump questions
Do you service heat pumps in Henderson?
Yes. Green Valley, Anthem, and Inspirada. See the Henderson area page.
Why is my heat pump blowing cold air in winter?
Often a defrost cycle, auxiliary heat staging, or the control wiring, which our tech checks on site. Start with heat pump not heating.
