Why is my heat pump not heating or cooling?
Common heat pump issues: frozen outdoor unit, refrigerant leak, faulty reversing valve (won't switch modes), or defrost control problems. Heat pumps are complex systems that provide both heating and cooling—proper diagnosis requires specialized training. Kodiak technicians are heat pump certified.
Call (704) 821-3632 for heat pump diagnosis.
Warning Signs
Signs You Need Heat Pump Repair
Don't ignore these warning signs. Early diagnosis can prevent costly repairs.
Not Heating or Cooling
Heat pump not providing adequate heating or cooling indicates a system malfunction.
Running Constantly
If your heat pump never shuts off, it could be low on refrigerant, have a stuck reversing valve, or other issues.
Strange Noises
Grinding, squealing, or unusual sounds indicate mechanical problems needing repair.
Ice Building Up
Excessive ice on the outdoor unit (beyond normal defrost cycling) indicates a problem.
Emergency Heat Always On
If your auxiliary/emergency heat runs constantly, your heat pump may not be functioning properly.
High Energy Bills
A sudden spike in energy costs often means your heat pump is working inefficiently.
Experiencing Any of These Issues?
Don't wait for a complete breakdown. Early diagnosis can save you hundreds in repairs.
About Our Heat Pump Repair in Charlotte
Heat pumps handle both heating and cooling for Charlotte homes, which means they run year-round with almost no off-season. That constant operation makes them more susceptible to wear than systems that only run half the year. When your heat pump stops heating in winter or cooling in summer, you need a technician who understands the dual-mode complexity of these systems — not just an AC guy who treats every outdoor unit the same. Kodiak Heating and Cooling provides expert heat pump repair services across Charlotte and Union County. Our technicians are trained on all heat pump types including air-source split systems, packaged units, and ductless mini-splits from every major manufacturer. We diagnose the real problem, not just the obvious symptom, and we carry the most common heat pump parts on our trucks for same-day repairs.
Heat pump repair requires a different diagnostic approach than standard AC repair. Heat pumps use a reversing valve, defrost controls, auxiliary heat staging, and dual-mode operation that standard air conditioners do not have. A technician who is experienced only with cooling systems may miss heat-pump-specific failure modes like a stuck reversing valve, a failed defrost board, or improper auxiliary heat lockout settings. Our technicians understand these systems because we install, maintain, and repair them daily across the Charlotte metro area.
The most common heat pump repairs we see in Union County include refrigerant leaks causing reduced capacity in both modes, reversing valve failures that prevent the system from switching between heating and cooling, defrost board malfunctions that lead to ice buildup on the outdoor coil, contactor and capacitor failures from continuous year-round operation, and thermostat communication issues between the indoor and outdoor units.
Charlotte's climate is ideal for heat pump operation — mild winters mean the system runs efficiently in heating mode for most of the season. But that advantage comes with a tradeoff: because heat pumps run 10-12 months per year here instead of the 6-7 months that a cooling-only system operates, components accumulate wear faster. Regular heat pump maintenance is critical to catching problems before they escalate into expensive failures.

LOCAL EXPERTISE
Common Heat Pump Problems in Charlotte Homes
Year-round operation means year-round wear. Here is what fails most often.
Heat pumps in the Charlotte area face a unique set of challenges because they operate in both heating and cooling modes with very little downtime. Understanding the most common failure points helps you recognize problems early and avoid emergency situations.
Reversing Valve Failure
The reversing valve switches your heat pump between heating and cooling modes. When it fails or gets stuck, the system either heats when it should cool, cools when it should heat, or loses capacity in one mode. This is a heat-pump-specific repair that requires proper diagnosis — replacing a reversing valve unnecessarily is expensive, and the real problem is sometimes a faulty solenoid coil rather than the valve itself.
Defrost Board and Sensor Issues
During Charlotte winters, moisture from the air freezes on the outdoor coil. The defrost board monitors outdoor coil temperature and initiates a defrost cycle to melt the ice. When the board or its sensor fails, ice accumulates unchecked and the system loses heating capacity. If you see heavy frost or ice buildup on your outdoor unit that persists for more than an hour, shut the system off and call for service.
Refrigerant Leaks
Refrigerant leaks affect heat pumps exactly as they affect air conditioners — reduced capacity and increased energy consumption. However, because heat pumps use the same refrigerant charge for both heating and cooling, a leak that develops in summer may not become noticeable until winter when heating demand is higher. Regular maintenance that includes superheat and subcooling measurements catches slow leaks before they cause compressor damage.
Auxiliary Heat Running Constantly
Heat pumps in Charlotte homes typically have electric resistance backup heat that activates when outdoor temperatures drop below the heat pump's efficient range. If your thermostat shows "AUX" or "EM HEAT" running frequently during mild weather (above 40°F), the heat pump is not carrying the load and needs service. Running on auxiliary heat continuously can double or triple your electric bill.
Compressor Hard Starting
Because heat pump compressors cycle more frequently than AC-only compressors, the start capacitor and contactor wear out faster. Hard starting — a brief hesitation, buzzing, or clicking before the compressor engages — indicates the capacitor is weakening. This is an inexpensive preventive repair ($150-250) that avoids a much more expensive compressor burnout down the road.
Thermostat and Control Board Communication
Modern heat pumps rely on communication between the thermostat, indoor unit control board, and outdoor unit control board to stage heating and cooling properly. Loose wires, corroded connections, or failing control boards can cause erratic behavior — the system may short-cycle, fail to switch modes, or run auxiliary heat unnecessarily. Diagnosing communication issues requires a technician with heat-pump-specific training.
SYSTEM KNOWLEDGE
Heat Pump Repair vs AC Repair: Why It Matters
A common frustration homeowners experience is calling an HVAC company for heat pump service and getting a technician who treats it like a standard air conditioner. While heat pumps share many components with air conditioners — compressors, coils, fans, refrigerant — they also have components and operating modes that AC-only systems do not. The reversing valve, defrost controls, auxiliary heat staging, and dual-capacity operation all require specific knowledge to diagnose correctly.
Here is a practical example: a homeowner calls because their system is not heating well. An AC-focused technician might check the thermostat and refrigerant charge, find both acceptable, and shrug. A heat-pump-trained technician would also check the reversing valve operation, verify defrost cycling, measure the temperature differential across the outdoor coil in heating mode, check auxiliary heat lockout settings, and evaluate whether the system is properly sized for heating load — which is calculated differently than cooling load in Charlotte's climate.
At Kodiak, our technicians work on heat pumps daily. We see the full spectrum of issues specific to these systems, and we carry heat-pump-specific parts like reversing valve solenoid coils, defrost boards, and outdoor thermistors on our trucks. When you call us for heat pump repair, you get a technician who knows these systems — not someone guessing from an AC repair manual.

Heat Pump Repair FAQ
Everything Charlotte homeowners need to know about heat pump repair
How much does heat pump repair cost in Charlotte?
Heat pump repairs in Charlotte typically cost $200-$1,200 depending on the issue. Common repairs like capacitor replacement cost $200-$300, reversing valve repairs run $600-$1,200, and compressor replacement costs $1,200-$3,500. We charge $89 diagnostic (waived with repair). Financing from $45/month.
Why is my heat pump not heating in Charlotte winter?
Common causes include frozen outdoor coils, low refrigerant, reversing valve failure, defrost cycle issues, or thermostat problems. Learn more about heat pump vs furnace options. We provide same-day diagnostics to identify the exact cause and get your heat working.
Is it normal for my heat pump to ice up?
Brief icing during defrost cycles is normal, but continuous ice indicates a problem: low refrigerant, dirty coils, failed defrost control, or airflow restrictions. Learn about HVAC freezing issues. Turn off your heat pump and call us for same-day service to prevent compressor damage.
Why is my heat pump running constantly but not heating well?
Heat pumps lose efficiency below 35°F. If yours runs constantly in cold weather, it may be undersized, low on refrigerant, or have a failing compressor. This could also cause high energy bills. We'll diagnose and provide honest repair vs replacement recommendations.
Should I repair or replace my heat pump?
If your heat pump is under 10 years old and repair costs less than 50% of replacement, repair usually makes sense. For units 12+ years old needing major repairs (compressor, reversing valve), replacement may be smarter. Use our repair calculator to help decide.
Do you offer emergency heat pump repair?
Yes! We provide emergency heat pump repair in Charlotte with same-day service. No after-hours fees—just honest, upfront pricing. Charlotte's winter temperature swings mean you need reliable heating when it gets cold.
What brands of heat pumps do you repair?
We repair all major heat pump brands: Carrier, Trane, Lennox, Rheem, Goodman, Bryant, York, American Standard, Mitsubishi (mini-splits), and more. Our technicians have extensive experience with both ducted and ductless systems.
Why is my auxiliary/emergency heat running all the time?
Auxiliary heat should only run when it's very cold or during defrost. If it runs constantly, your heat pump likely has low refrigerant, a bad reversing valve, or thermostat issues. Aux heat causes high energy bills—get it fixed to save money.
How quickly can you repair my heat pump?
Most heat pump repairs take 1-3 hours. Simple repairs like capacitors take under an hour. Reversing valve or refrigerant leak repairs may take 2-4 hours. We stock common parts for faster Charlotte service. Average emergency response time under 2 hours.
Can you repair heat pumps in both heating and cooling mode?
Absolutely! Heat pumps are complex because they both heat and cool. We test both modes, check the reversing valve, verify defrost cycles, and ensure proper operation year-round. Charlotte's climate demands reliable heating AND cooling.
What warranty do you provide on heat pump repairs?
We provide a 1-year parts and labor warranty on all heat pump repairs. We stand behind our work—check our customer reviews to see why Charlotte trusts us.
Do you service ductless mini-split heat pumps?
Yes! We repair and service all ductless mini-split brands including Mitsubishi, Daikin, Fujitsu, LG, and Samsung. Our technicians are trained on multi-zone systems, wall units, and cassettes. Learn about mini-splits vs central air.
Why is my heat pump making loud noises?
Loud noises can indicate serious issues: grinding (bearing failure), squealing (belt or motor), rattling (loose parts), or banging (reversing valve). Learn more about HVAC noise issues. Persistent loud sounds need immediate attention. We provide same-day diagnostics.
How often should I service my heat pump in Charlotte?
Heat pumps work year-round in Charlotte (heating AND cooling) so they need service twice yearly—spring and fall. This prevents 90% of breakdowns and maintains efficiency. Our maintenance plans start at $199/year for both seasonal tune-ups.
