Heat Pump Problems We Fix in Lisle
We repair ducted heat pumps, dual-fuel systems and ductless mini-split heat pumps across Lisle. The fixes we make most are capacitors, contactors, defrost sensors, defrost control boards and crankcase heaters, plus refrigerant leaks found with a nitrogen pressure test. Reversing valves and compressors are less common but we replace those too.
How We Diagnose Heat Pumps in Lisle
A heat pump combines refrigeration, airflow, electrical parts and controls, so we test the whole system. The thermostat, reversing valve, defrost operation, sensors, motors and refrigerant all get checked before we name the failed part. Trucks carry common parts for most brands.
When to Repair and When to Replace a Lisle Heat Pump
Heat pumps here typically last 12 to 15 years. If yours is younger and the problem is electrical or a defrost control, repair it. If it is older and needs a compressor, coil or reversing valve, compare it with a new system first. Remaining warranty can change the answer, so we check it.

Lisle Heat Pump Repair FAQs
How much does heat pump repair cost in Lisle?
Most heat pump repairs in Lisle cost $275 to $765, flat-rate with parts and labor. A capacitor is $275 to $348, a defrost sensor $340 and a defrost control board $765. The $75 diagnostic ($99 evenings, weekends and holidays) is waived when you approve the repair.
Why is my heat pump blowing cool air in heating mode?
Heat pump air feels cooler than furnace air, but noticeably cold air can mean a stuck reversing valve, a defrost problem, low refrigerant or backup heat that is not coming on. We test each one.
Do you service heat pumps in Lisle?
Yes. We repair heat pumps across Lisle (60532) from our Streamwood shop, about 32 minutes away.
How does a heat pump defrost cycle work?
The system briefly runs in cooling mode to warm the outdoor coil and melt frost. If ice keeps building, a sensor, control board or reversing valve is often the cause.
Will you work on a heat pump another company installed?
Yes. We repair all major brands and file manufacturer warranty claims for covered parts.
How do I know my heat pump is near the end?
Rising repairs, refrigerant leaks, poor heating in cold weather and an age past 12 to 15 years are the usual signs.
What does a heat pump tune-up include?
Electrical tests, refrigerant check, coil and drain cleaning, defrost and reversing valve checks and a look at the backup heat.
