Electrical Troubleshooting & Repair
Is Your A/C Behaving Erratically or Not Responding? Modern HVAC systems rely on sophisticated electrical controls. Problems with circuit boards, relays, fuses, or wiring can cause mysterious shutdowns, intermittent operation, or complete failure. Our certified technicians have the expertise and tools to diagnose and repair even the most complex electrical faults safely and efficiently.
01.
Control Board Diagnosis & Repair
The system's "brain" can fail due to power surges, moisture, or age. We diagnose faulty boards by checking for burnt components, poor solder joints, and correct input/output signals. We repair minor issues or replace the board with an OEM-compatible unit, ensuring proper programming.
02.
Relay & Sequencer Testing & Replacement
These electromechanical switches control the operation of fans, compressors, and heat strips. We test coils and contacts for failure and replace faulty relays to restore proper system sequencing and prevent components from not turning on or getting stuck on.
03.
Fuse & Breaker Protection Analysis
We check high-voltage fuses in the disconnect and low-voltage fuses on the control board. We don't just replace blown fuses—we find out why they blew, whether it's a short circuit, a failing component, or a power surge.
04.
Complete Wiring Harness & Connection Inspection
We inspect wiring for rodent damage, corrosion, loose connections, and overheating at terminals. We repair or replace compromised wiring, ensuring all connections are secure and meet electrical code for safety and reliability.
