ABOUT THIS SERVICE

HEAT PUMP REPAIR & DIAGNOSIS
FROM UTAH'S LOCAL EXPERTS

Your heat pump handles both heating and cooling by reversing refrigerant flow between seasons — that dual-mode complexity creates more failure points than a standard furnace or AC. Reversing valves stick. Defrost controls quit. Compressors burn out from year-round loads. We service all major brands including Lennox, Trane, Carrier, Bryant, Rheem, York, Goodman, American Standard, and Daikin. Most repairs happen same-day with parts on the truck.

Utah's elevation and temperature swings from -10°F to 107°F stress heat pumps harder than standard systems. A heat pump running at 4,500 feet works against thinner air and colder winter temps — both cut efficiency and accelerate wear. We diagnose reversing valve failures, refrigerant leaks, defrost sensor faults, compressor issues, and low-output problems specific to altitude and extreme cold. If repair doesn't make sense, we'll tell you honestly and explain why replacement pays back faster.

We serve all of Salt Lake County, Utah County, Davis County, Summit County, Wasatch County, and Tooele County. Same-day appointments available on most calls. Emergency dispatch runs 24/7/365 — including holidays.
WHAT'S INCLUDED

COMPLETE HEAT PUMP REPAIR & DIAGNOSIS
COVERAGE IN UTAH

From defrost failures to reversing valve problems, compressor burnout to refrigerant leaks — we handle every aspect of heat pump diagnosis and repair across the Wasatch Front. Our licensed technicians arrive equipped for same-day repairs on most calls.
❄️
Defrost Cycle Repair
Your heat pump icing over in winter is not normal. The defrost cycle should kick in automatically to melt ice buildup on the outdoor coil. If it's not working, the entire unit loses efficiency and can lock up completely. We troubleshoot defrost sensors, control boards, and reversing valve timing to restore proper winter operation. This is a specialty repair — most techs skip it and suggest replacement. We fix it first.

🔄
Reversing Valve Service
The reversing valve switches refrigerant flow from heating mode to cooling mode and back. When it sticks or fails, your heat pump only works in one direction — heat OR cool, not both. We replace faulty valves, test solenoid coils, and verify proper mode switching under load. A failed reversing valve doesn't mean a full system replacement — in most cases it's a repairable component.

📋
Heat Pump Tune-Up
Annual maintenance catches defrost faults, refrigerant leaks, and worn contactors before they cause a breakdown. We check both heating and cooling modes, test the reversing valve, inspect electrical connections, clean coils, and verify refrigerant charge on both sides of the cycle. A heat pump runs year-round — it needs attention twice a year, not once. Spring and fall checkups for $89 each.

Low Heat Output Diagnosis
If your heat pump runs but barely heats the house when temps drop below 30°F, it's likely undersized for Utah winter loads, low on refrigerant, or the auxiliary heat isn't kicking in when needed. We test output temperature at the vents, measure refrigerant charge in heating mode, check backup strip heat operation, and compare capacity to your home's actual heat loss at elevation. Sometimes the fix is a repair. Sometimes it's adding backup heat. We'll show you both options with real numbers.

SIGNS YOUR HEAT PUMP
NEEDS ATTENTION

🧊
Icing in Winter or Won't Defrost
If your outdoor unit stays coated in ice for hours — or never melts off at all — the defrost cycle has failed. This locks the unit in a block of ice, kills efficiency, and can burn out the compressor. Don't ignore it through winter.
Don't ignore this
🔄
Works in One Mode, Not the Other
Heat pump heats fine but won't cool in summer — or cools fine but won't heat in winter? That's almost always a stuck or failed reversing valve. The system is trapped in one mode and can't switch refrigerant flow direction.
Don't ignore this
🌡️
Barely Heats Below 30°F
Heat pumps lose capacity as outdoor temps drop — that's physics. But if your system struggles or quits entirely below 30°F, it's either low on refrigerant, the backup heat isn't kicking in, or it was undersized for Utah winter from the start. All fixable or supplementable.

COMMON QUESTIONS

HEAT PUMP REPAIR & DIAGNOSIS
FREQUENTLY ASKED QUESTIONS

We commit to 120-minute response times for true heat pump emergencies across Salt Lake County, Utah County, and surrounding areas. Real people answer your call 24/7 — not an answering service — and dispatch immediately. Most customers see us within the hour.

Common repairs range from $200–$550 for reversing valve solenoids, defrost sensors, or refrigerant issues, to $1,200–$2,500 for compressor or full reversing valve replacement. We provide a flat-rate quote after diagnosis — before we start any work. No surprise fees. If repair doesn’t make financial sense, we’ll tell you honestly.

If your system is under 8 years old and the repair is under $800, repair usually wins. If it’s over 12 years old or needs a compressor or reversing valve assembly, replacement often pays back faster through energy savings and reliability. Heat pumps work harder than standard AC units — dual-season loads accelerate wear. We’ll walk you through both options with real numbers — never pressure you either way.

We service all major residential heat pump brands: Lennox, Trane, Carrier, Bryant, Rheem, York, Goodman, American Standard, Daikin, Mitsubishi, Amana, Payne, and more. Our technicians are trained on all residential heat pump systems and carry parts for the most common brands.

Ice buildup on the outdoor coil in winter is normal during operation — the defrost cycle should melt it off every 30–120 minutes. If ice stays for hours or never melts, the defrost control board, sensor, or reversing valve has failed. Low refrigerant also causes chronic icing. Left alone, it kills efficiency and can burn out the compressor. We diagnose and fix the defrost cycle — most techs skip this and suggest replacement instead.

Yes — but efficiency drops as outdoor temps fall. Most heat pumps lose significant capacity below 25°F and need backup heat (electric resistance strips or a gas furnace) to keep up. At Utah’s elevation (4,200–4,800 ft), thinner air makes the compressor work harder in extreme cold. A properly sized heat pump with backup heat handles Utah winters fine. If yours struggles below 30°F, it may be undersized, low on refrigerant, or missing backup heat. We can diagnose and fix all three.

Yes — all our technicians are Utah state licensed HVAC contractors (issued by DOPL) and we carry full liability insurance. Heat pump work requires refrigerant handling certification and state licensing. We pull permits for any system replacement and handle all inspections.
