Feedback From Homeowners We Serve
Here is what neighbors near Crystal Lake say about working with us.
What Crystal Lake homeowners say
“We had an emergency with an electrical component in our HVAC system. I had an appointment slot a couple hours later with no emergency/after hours/weekend upcharge. Pricing was straightforward and I felt like he gave us honest, good advice about what repairs to do now and future options! I would recommend them to a friend (like a friend recommended them to me) for the service and very friendly staff at every stage! This felt like an emergency when we called them and ended up feeling more like a minor inconvenience.”

Crystal Lake Heat Pump Repair FAQs
What does a typical heat pump repair cost in Crystal Lake?
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.
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 soon can you get to Crystal Lake for a heat pump repair?
Usually the same day when a truck is open. Our shop is about 40 minutes from Crystal Lake.
Why is my outdoor heat pump covered in ice?
Usually a defrost problem: a failed defrost sensor ($340) or defrost control board ($765). Low refrigerant and poor airflow can also cause it. Turn the system to emergency heat and call us.
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.
When should I service my heat pump?
Spring for cooling and fall for heating. A fall check confirms the defrost cycle and backup heat before cold weather.
