Your Heat Pump System Isn’t Heating or Cooling
A heat pump is more complex than a standard air conditioner—it heats in winter, cools in summer, and switches seamlessly between modes. When something goes wrong, you lose both comfort and efficiency in one system. Lake Area Heating & Air brings specialized heat pump expertise to your repair, using diagnostic tools that pinpoint heating-cycle failures, cooling problems, and reversing-valve issues that non-specialists often misdiagnose. We repair American Standard and Gree heat pump systems with the same precision we install them, backed by 18 years of hands-on experience with both ducted and ductless units.
Heat Pump Repair Specialists
Heat pumps operate differently than air conditioners; they reverse refrigerant flow to switch between heating and cooling modes, and that reversing valve is a common failure point. We diagnose both heating and cooling failures with expertise specific to heat pump operation. Standard air conditioning technicians often misdiagnose heat pump problems because they don’t understand the heating cycle.
We’re transparent about cost-benefit. If your compressor or reversing valve has failed on an aging unit, we’ll explain whether repair or replacement makes economic sense long-term. You won’t face pressure to replace a system that’s still serviceable, and you won’t be pushed to repair a dying unit that’s approaching the end of its economic life.
As a Premier Dealer and Select Dealer, we have fast access to OEM parts, factory technical support, and schematics specific to your heat pump model. That dealer relationship means we can source hard-to-find components and troubleshoot complex issues with manufacturer guidance, keeping your repair on schedule and within budget.
Military discipline shapes how we approach a failing heat pump. We follow a systematic diagnostic protocol—testing refrigerant charge in both heating and cooling modes, verifying reversing valve operation, measuring airflow on each cycle—and document every reading. You’ll understand exactly what failed and why before any work begins.
We installed many of the heat pumps we repair, so we know your system’s history and how it was set up. That continuity means faster troubleshooting, reliable recommendations, and standing behind our work. Your long-term comfort is linked to our reputation, so we invest in getting repairs right the first time.
Whether your issue is a refrigerant leak, a failed compressor, or a heating-mode failure, we evaluate your whole system—ductwork, thermostat, backup heating—to ensure the repair solves the problem and doesn’t mask a larger issue upstream.
Schedule Your Heat Pump Diagnostic
Contact us for a diagnostic visit. We’ll identify whether the problem is heating-cycle failure, cooling-mode breakdown, a component failure, or an electrical issue, and walk you through repair options and realistic costs before any work begins.
Signs Your Heat Pump Needs Professional Repair
Your heat pump defaults to backup electric heating and won’t switch to heat-pump mode, or it cycles between heat pump and backup heat erratically. This indicates a reversing valve stuck in cooling mode, low refrigerant charge preventing efficient heating, a failed compressor, or a thermostat misconfiguration. Running on backup heat alone wastes energy. A diagnostic will confirm whether the reversing valve is stuck, refrigerant is low, or control logic is failing.
You set the thermostat to cooling but the system produces warm air or runs in heating mode. A stuck reversing valve, incorrect thermostat wiring, failed solenoid coil on the valve, or a control board failure can trap your heat pump in heating cycle. Forcing heating in summer is uncomfortable and wastes electricity. Diagnostic testing isolates the valve, solenoid, and control circuits to pinpoint the culprit.
You hear the compressor running but air barely flows from your supply vents in both heating and cooling modes. Causes include a clogged air filter, blocked ductwork, blower motor failure, or control issues affecting the blower. Low airflow stresses the compressor and reduces comfort; addressing it prevents compressor damage and improves performance immediately.
Frost or ice buildup on your outdoor heat pump unit is normal in winter—but if ice builds excessively and the system doesn’t run its defrost cycle to shed it, the heat pump loses heating capacity. A faulty defrost timer, failed thermostat sensor, or stuck reversing valve can disable the defrost cycle. Proper diagnosis confirms which component is preventing the system from thawing itself.
A grinding, squealing, or hissing sound during either heating or cooling mode signals a failing compressor bearing, loose mounting bracket, refrigerant leak from the reversing valve, or a blower motor problem. These noises are warnings—ignoring compressor noise allows internal damage to accelerate, making repair more costly. Early diagnosis saves money and restores quiet operation.
You adjust the setpoint or switch from heating to cooling, but the system doesn’t respond. The thermostat itself may be faulty, wiring to the heat pump may be loose, the reversing valve solenoid may have failed, or the control board may be damaged. Diagnostic testing checks thermostat continuity, verifies wiring connections, and tests the solenoid coil to isolate the failure.
Our Heat Pump Repair Methodology
Step 1 of 5
Call us and describe exactly what’s happening—won’t heat, won’t cool, low airflow, running on backup heat constantly, making noise, or cycling erratically—and whether the problem occurs in heating mode, cooling mode, or both.
Step 2 of 5
Our technician arrives with professional heat pump diagnostic equipment and systematically tests both heating and cooling modes to pinpoint what’s failing.
Step 3 of 5
We explain what we found during testing and present repair options with clear cost comparisons.
Step 4 of 5
Once approved, our technician performs the repair and verifies operation in both heating and cooling modes.
Step 5 of 5
We confirm your heat pump is operating properly in both modes and leave you with a clear record of what was repaired.
Heat Pump Repairs We Specialize In
The reversing valve switches your heat pump between heating and cooling modes. When it sticks or fails, your system may run only in heating, only in cooling, or cycle between them erratically. We test valve operation in both modes using pressure gauges and temperature measurement, locate the stuck valve, and repair or replace it to restore full heating and cooling operation. Reversing valve replacement is a heat pump specialty—this is one of the most common heat pump failures we encounter.
Low refrigerant charge reduces both heating and cooling capacity and strains the compressor. We use electronic detectors to locate leaks in your system, assess whether the leak is in the outdoor unit, indoor connections, or ductless evaporator coils, seal the breach with EPA-approved methods, and recharge to manufacturer specifications. Proper leak sealing and recharging restores comfort in both heating and cooling modes.
A worn or failed compressor cannot maintain refrigerant pressure in either heating or cooling mode. We thoroughly test compressor operation—measuring discharge pressure, checking for electrical continuity, and verifying proper current draw—and document the failure before recommending replacement. We compare replacement cost against your system’s age and efficiency to help you decide whether repair or a new heat pump makes more economic sense.
A faulty thermostat won’t trigger heating or cooling, may fail to switch between modes, or may lock your system in one mode. We test thermostat continuity, check wiring connections to the heat pump, and confirm signal response. We repair loose wiring, replace a faulty thermostat, or upgrade to a programmable smart thermostat that learns your schedule and optimizes both heating and cooling efficiency.
Heat pump outdoor units naturally frost in winter; the defrost cycle defrosts the coil periodically to maintain heating efficiency. If defrost fails, ice builds up and blocks airflow, reducing heating capacity. We test the defrost timer, thermostat sensor, and solenoid coil that triggers the defrost cycle, identify what’s preventing the cycle from running, and repair or replace the failed component.
If your heat pump compressor is running but produces no airflow in heating or cooling, the blower motor is likely failed. We perform diagnostics to confirm motor failure, then replace the motor and test airflow in both modes to ensure the fix worked. A functioning blower motor restores comfort immediately and prevents compressor strain from running with restricted airflow.
A failed run capacitor stops your compressor or blower motor, preventing heating and cooling. Capacitors often fail first and catch the problem early, before more expensive compressor or motor damage occurs. We carry common capacitor sizes on our truck and can diagnose and replace one efficiently during your service visit.
Some heat pumps include electric backup heating that activates in extreme cold when the heat pump alone can’t keep up. If backup heat never engages when the outdoor temperature drops, a wiring problem, failed contactor, or faulty thermostat stage may be preventing it. We test the backup circuit, confirm the thermostat is wired correctly, and restore backup heat operation for reliable winter comfort.
