Heat pump not
heating or cooling?
Heat pumps are complex systems that require specialized diagnostics. Example HVAC's TDLR certified technicians are trained on every major manufacturer — available 24/7.
Diagnosis first.
Repairs second.
Heat pump problems are often misdiagnosed — even by experienced technicians. A system that seems like it's heating poorly might have a reversing valve issue, a refrigerant deficiency, or a defrost cycle malfunction. We get to the actual cause — not just the symptom.
With years of combined technical expertise on our team, we've seen it all. Our TDLR certified technicians (License DEMO-000000) carry the manufacturer-specific training needed to service all major brands correctly.
Common heat pump issues we fix
-
System stuck in heating or cooling mode — won't switch
-
Reversing valve failure — no heating or cooling in one direction
-
Refrigerant leaks — reduced efficiency, warm air
-
Ice buildup on the outdoor unit — defrost cycle failure
-
Defrost cycle not activating — frost accumulation, poor heating
-
Capacitor or compressor failure — system won't start
-
Thermostat or control board issues — communication errors
The four issues we see
most often.
Reversing Valve Failure
The reversing valve is what allows a heat pump to switch between heating and cooling modes. When it fails, your system may be stuck in one mode — or produce only lukewarm air in either direction. This is one of the most commonly misdiagnosed heat pump repairs.
Refrigerant Leaks
Heat pumps run on a sealed refrigerant circuit. Leaks — even small ones — cause reduced efficiency, warm or inconsistent air, and compressor damage if left unchecked. We locate leaks precisely and repair them to manufacturer specification without overcharging.
Defrost Cycle Issues
In cold weather, frost accumulates on the outdoor coil. The defrost cycle melts it — but when the defrost sensor, reversing valve, or board fails, ice builds up and chokes airflow. This causes heating loss and can damage the compressor through unnecessary strain.
Compressor & Electrical Failures
The compressor is the heart of your heat pump — and the most expensive component to replace. Capacitor failures, electrical shorts, and compressor seized-start conditions are among the most common causes of complete heat pump failure. Early diagnosis prevents catastrophic damage.
Not every HVAC tech
is a heat pump tech.
Heat pumps are fundamentally different from conventional AC and furnace systems. They require specialized training on reversing valves, defrost logic, variable-speed compressors, and dual-fuel configurations. A technician who's great at fixing furnaces may not have the heat-pump-specific experience your system needs.
Example HVAC technicians receive ongoing manufacturer-specific training on heat pump systems across all major brands we carry. That means faster, more accurate diagnoses — and repairs that actually fix the problem the first time.
TDLR Certified Technicians
State licensing (DEMO-000000) with specialized heat pump manufacturer training.
All Major Brands Serviced
Authorized dealer status means factory-trained techs and direct manufacturer support.
Accurate Diagnosis First
Heat pump problems are often misdiagnosed. We test systematically before we touch a part.
No Commissions, No Upsells
Our techs are paid salaries — not commissions. They recommend what you actually need.
Heat pumps don't fail
on a convenient schedule.
When your heat pump goes out on a holiday weekend or in the middle of the night, you need someone who answers the phone — not an answering service. Example HVAC phones are answered 24 hours a day, 7 days a week, 365 days a year. Our technicians are on call for the emergencies that can't wait.
When to call for emergency service
-
Heat pump is completely non-functional in below-freezing temperatures
-
You hear grinding, buzzing, or clicking sounds from the outdoor unit
-
System trips the breaker repeatedly — don't keep resetting it
-
Unusual burning smell or visible smoke from the unit
-
Total lack of heating in weather below 40°F — safety issue fast

Heat pump repair
questions answered.
Why is my heat pump running but not heating or cooling?
This is one of the most common heat pump complaints — and it's almost always one of three things: a stuck reversing valve (most common), a refrigerant leak causing insufficient cooling/heating capacity, or a defrost cycle problem that's letting the outdoor coil freeze over. We diagnose the actual cause with systematic testing before recommending any repair.
Is it normal for my heat pump to ice up in winter?
Some frost on the outdoor coil in cold, humid weather is normal. The heat pump is designed to defrost itself periodically. What isn't normal is heavy ice accumulation that doesn't clear — that indicates a failed defrost cycle, a bad defrost sensor, or low refrigerant. If you see thick ice buildup that persists, schedule a service call.
How much does heat pump repair cost?
Heat pump repair costs vary significantly based on the problem. Common repairs like capacitor replacement run $200–$400. Reversing valve repairs or refrigerant leaks can run $400–$900. Compressor failures — the most serious repair — can run $1,200–$2,500 depending on the system. We provide written estimates before every repair. No surprises.
Should I repair or replace my heat pump?
If your heat pump is less than 10 years old and the repair cost is under $1,000, repair is usually the right call. If it's over 12 years old, has had multiple compressor issues, or needs a repair over $1,500, replacement starts making more sense. We give you an honest assessment — not a sales pitch — so you can make the right decision for your home and budget.
