Heat Pump Problems We Fix in Carol Stream
Most Carol Stream heat pump calls come in one of two seasons: the first hot week of summer and the first cold snap of fall. In winter, the usual complaints are an outdoor unit caked in ice, cool air from the vents or a heat pump that runs nonstop. In summer, it is weak cooling or an outdoor unit that will not start. Capacitors, contactors, defrost controls and reversing valves cause most of them.
Our Heat Pump Repair Process in Carol Stream
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.
Should You Replace Your Carol Stream Heat Pump?
Small parts are almost always worth fixing: a capacitor runs $275 to $348 and a defrost sensor $340. Big repairs on an older heat pump deserve a second look. A compressor is $2,935 and a reversing valve $1,470, so on a heat pump past 10 to 12 years, we will price a replacement too.

Heat Pump Repair FAQs for Carol Stream
Is heat pump repair priced by the hour?
No. Every repair is flat-rate with parts and labor included. Most cost $275 to $765 in Carol Stream.
Why does my heat pump heat poorly when it is very cold?
Output drops as it gets colder outside. Dual-fuel systems switch to the furnace and electric systems use heat strips. If that handoff is not happening, we check the thermostat and controls.
How far is Pure Comfort from Carol Stream?
About 25 minutes from our shop in Streamwood. We cover Carol Stream homes in 60188.
Can a frozen heat pump damage itself?
It can, if it keeps running iced up. Use emergency heat until we diagnose the defrost system.
Do you repair ductless mini-split heat pumps?
Yes. We repair ductless heat pumps, including sensors ($330) and control boards ($1,065), along with ducted systems.
When is a heat pump not worth fixing?
When an older unit needs a compressor ($2,935), keeps leaking refrigerant or never kept the house comfortable. Otherwise, repair is usually the better value.
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.
