Case Overview

Late one winter afternoon in Knoxville, a new homeowner noticed the indoor temperature had dropped into the 50s despite the thermostat calling for heat. The upstairs unit was running, but the outdoor fan didn’t turn on and the house never warmed up. Concerned that something was stuck, she reached out to schedule a visit with HEP.

How the Problem Was Solved

When the HEP technician arrived, the outdoor unit was cycling but failing to escape the defrost mode. A close inspection revealed:

• A loose connection in the auxiliary heat kit wiring, preventing proper heat output.
• A malfunctioning control board that oversees the defrost cycle, causing the unit to stay in that mode too long.

The technician re-secured the displaced wiring and replaced the faulty defrost control board. After those repairs, both heating and cooling cycles were tested and confirmed working as intended. Warm air flowed once again, and the homeowner was relieved and happy with the result.

Key Takeaways for Homeowners

Keeping your home comfortable and your HVAC system in top shape doesn’t require a toolbox—just a few smart habits:

• Schedule Annual Check-Ups: Routine inspections can catch loose wires or aging control boards before they leave you in the cold.
• Know Your Defrost Cycle: Heat pumps need occasional defrosting, but if the system seems stuck, it’s time to call a professional.
• Keep the Area Clear: Ensure at least two feet of clearance around your outdoor unit and remove leaves, snow, or debris for proper airflow.
• Value Professional Diagnostics: Specialized tools like clamp meters help HEP technicians pinpoint hidden electrical or control issues quickly.

Why Professional Service Matters

When comfort systems act up, small malfunctions can quickly become big problems. HEP technicians in Knoxville bring the training, experience, and equipment needed for both simple repairs and complex board replacements. For reliable service in Heating and Air Conditioning, trusting the experts is the best way to ensure year-round comfort in your home.
