Stuck in Defrost? Won't Switch Modes? Heat Pump Repair in Lebanon, MO

Name: AAA Pro HVAC
Telephone: +1-866-805-8548
Price range: $$
Rating: 4.9

Heat pumps fail differently than standard AC or furnace systems, and diagnosing them requires understanding the reversing valve and defrost board specifically.

Auxiliary heat strip issues are checked alongside the heat pump itself.

A heat pump that seems to be 'not heating' is often actually a reversing valve or defrost cycle problem, which a technician trained mainly on standard ac systems can easily misdiagnose, which is exactly why heat pump repair calls in Lebanon, MO get treated with urgency, not a next-available-Tuesday slot.

Our Full Range of Heat Pump Repair Services

Every job starts with a real diagnosis, not a guess — here's the full scope of what our heat pump repair technicians handle across Lebanon, MO.

Reversing Valve Diagnosis & Repair

A stuck reversing valve is the single most common reason a heat pump gets stuck in one mode. Techs handling reversing valve diagnosis & repair carry the specific parts and tools this job calls for, not a generic kit.

Defrost Cycle & Control Board Repair

An outdoor unit that ices over and never defrosts usually points to a failed defrost thermostat or control board timing issue. This is one of the most requested heat pump repair calls we get across Lebanon, MO.

Auxiliary / Emergency Heat Strip Repair

We test heat strip elements and the relay controlling them separately. This is one of the most requested heat pump repair calls we get across Lebanon, MO.

Refrigerant Charge & Leak Detection

Heat pump refrigerant charging follows different specs than standard AC systems, especially across heating and cooling modes. Techs handling refrigerant charge & leak detection carry the specific parts and tools this job calls for, not a generic kit.

Outdoor Unit Icing Diagnostics

Some icing is normal during defrost cycling; persistent icing that never clears points to a genuine fault. Techs handling outdoor unit icing diagnostics carry the specific parts and tools this job calls for, not a generic kit.

Ductless Heat Pump System Repair

Ductless mini-split heat pumps have their own fault-code language separate from central systems. Techs handling ductless heat pump system repair carry the specific parts and tools this job calls for, not a generic kit.

Before You Call: Heat Pump Repair Answers

Why is my heat pump blowing cold air when it's set to heat?+

This is one of the most common and most misdiagnosed heat pump failures.

Is ice on my heat pump's outdoor unit normal?+

Some frost during a normal defrost cycle is expected; ice that never clears points to a defrost board or thermostat fault.

How is heat pump repair different from regular AC repair?+

Heat pumps have a reversing valve, defrost cycle, and often auxiliary heat strips that standard AC systems don't have.

Why does my heat pump seem to run constantly in cold weather without ever feeling warm enough?+

If auxiliary heat isn't kicking in properly, that's a specific fault we can test for.

Do you repair ductless heat pump mini-splits?+

Yes — indoor head units and outdoor condensers on ductless heat pump systems are within our service scope.

How fast can a heat pump specialist reach Lebanon during winter?+
