Is Your Heat Pump Struggling to Keep Up?Heat pumps are powerful, but they require expert care. If you see these signs, you might be wasting money.
Outdoor Unit Frozen:
A light frost is normal, but if your unit is encased in a block of ice, the defrost cycle has failed. This can destroy your compressor quickly.
"Aux Heat" Won't Turn Off:
If your thermostat is stuck on "Emergency Heat" or "Aux Heat" when it’s not freezing outside, your bill will skyrocket. Call us to fix the sensor.
Blowing Cold Air:
Heat pumps blow cooler air than gas furnaces, but it should still be warm. If the air feels literally cold (room temp), you likely have a refrigerant leak or compressor issue.
Grinding Noises:
Since the outdoor unit runs all year, the motor bearings wear out faster. Loud noises mean a breakdown is imminent.
Spiking Energy Bills:
A heat pump should be more efficient than a furnace. If your bill jumped unexpectedly, the system isn't running in "efficiency mode."

Complete Heat Pump Solutions for Oklahoma
Expert Heat Pump Repair:
Heat pumps are complex technology. You need a tech who understands reversing valves and refrigerant pressures. We diagnose issues fast and get your system back to peak efficiency.
High-Efficiency Installation:
Looking to replace an old gas hog? We install modern Heat Pump systems (Carrier, Amana) that handle Oklahoma's summers and winters. We’ll help you choose the right "Dual Fuel" or electric setup for your home.
Year-Round Maintenance:
Because heat pumps run 365 days a year, they need double the care. Our tune-ups clean the coils and check the defrost controls so you don't get left in the cold (or heat).

Thank you Hardin’s Heating & Cooling for your efficient and excellent service. They replaced our unit after the other had died. We would not have survived the summer without you. God bless.

Previous repair was again making a similar noise as before; the return call was quick, the technician arrived when we were told, and the repair was still under warranty. Appreciate their service and will continue to use them for our HVAC needs.
Ron S.
This is a good company to deal with. They are locally owned and you get to communicate with the owner as needed. I got a completely new heat and air system and so far, so good. It runs more quietly and has a good warranty. They send out a crew of highly skilled technicians and get the job done right.
