Specialized Heat Pump Repair
& Diagnostics

Heat pumps are complex systems that require specialized training.

Don’t let a general handyman guess.

Heat Pumps Are Not Just “ACs”

Modern Heat Pumps (especially Daikin Fit or Mitsubishi units) are sophisticated computers.

They use Inverter Boards and Communicating Thermostats.

The Problem: An untrained technician can destroy a $1,000 inverter board by testing it incorrectly.
The Solution: Our technicians are factory-trained on the specific error codes and voltage diagnostics for modern variable-speed systems.

Outdoor Unit Frozen Solid: A little frost is normal in winter; a block of ice is not. This usually means a Defrost Board failure or low refrigerant.
“Auxiliary Heat” Stuck On: Is your electric bill huge? Your system might be running on expensive backup heat strips because the compressor isn’t engaging.
Stuck Reversing Valve: The system cools but won’t heat (or vice versa). We diagnose and replace faulty solenoid coils.
Thermostat Errors: “Communication Error” or blank screens on smart thermostats.

The #1 Issue: Water dripping down the wall. This is usually a clogged condensate line or mold buildup in the blower wheel.
Deep Cleaning: We perform a “Bib Kit” cleaning to pressure wash the inside of your mini-split without making a mess, removing mold and restoring airflow.

Complex systems need precise repairs. Get your Heat Pump running efficiently again.
