What Goes Wrong With Naperville Heat Pumps
We repair ducted heat pumps, dual-fuel systems and ductless mini-split heat pumps across Naperville. 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.
Step by Step: Heat Pump Repair in Naperville
First we confirm power and the thermostat signal. Then we test the outdoor unit: capacitor, contactor, fan motor and compressor. In heating season, we check the defrost sensor and board and whether the reversing valve shifts. Refrigerant comes last, measured by superheat and subcooling. You approve the price before we start.
Fix It or Replace It? Naperville Heat Pumps
A heat pump usually lasts 12 to 15 years here, a bit less than a furnace because it runs in both seasons. Repair makes sense when the failure is isolated, like a capacitor, contactor, defrost sensor or defrost board. Consider replacement when an older unit needs a compressor ($2,935) or a reversing valve ($1,470), or keeps leaking refrigerant. Replacement estimates are free.

Heat Pump Repair FAQs for Naperville
What does a typical heat pump repair cost in Naperville?
Usually $275 to $765. Bigger repairs cost more: a reversing valve is $1,470 and a compressor $2,935. Every price is flat-rate and written before work starts.
Is cold air from my heat pump normal in winter?
During a defrost cycle, briefly, yes. Cold air that lasts points to the reversing valve, defrost controls, refrigerant or backup heat.
Is Pure Comfort local to Naperville?
Yes. We are a family-owned company in Streamwood, about 40 minutes from Naperville.
What should I do if my heat pump is frozen?
Switch to emergency or auxiliary heat so the outdoor unit can thaw, check the filter and call for service. Do not chip the ice off the coil.
Will you work on a heat pump another company installed?
Yes. We repair all major brands and file manufacturer warranty claims for covered parts.
Is it worth replacing a heat pump compressor?
Only on a fairly new system or one still under parts warranty. On older units, a new heat pump is usually the better buy.
How often should a heat pump be serviced?
Twice a year is ideal, since it heats and cools. Our maintenance plan covers a tune-up in each season and saves members 10 to 15% on repairs.
