Heat Pump Acting Up After a Power Surge in Clayton
Clayton · September 2026 · Mario · From our service records
What the customer reported
A Clayton homeowner's property experienced a power surge, and the control boards in the heat pump and air handler were experiencing issues that could impact their ability to operate.
What we found and did
Mario turned off power to both units and replaced the defrost board in the heat pump on the left side of the home, then moved to the attic and replaced the control boards in the air handler. Although the new boards stopped displacing voltage, Mario noticed the thermostat was failing to send the proper voltage (half) to activate the equipment. He replaced the thermostat and re-tested system operations.
Result
The system re-tested without any further issues and was cooling properly at the end of the visit.
