What we found and fixed

When exterior digging or grading occurs near an outdoor condenser or buried electrical lines, the HVAC ground wire can be nicked or severed. That’s what happened here. A damaged ground wire compromises the fault path needed to safely clear electrical faults, creating potential shock and equipment risks.

Assessment: Verified power off to the affected HVAC circuit and inspected the outdoor equipment and conduit path to locate the damaged grounding conductor.
Repair: Restored the equipment grounding connection using code-compliant materials and secure mechanical bonding to ensure a low-impedance fault path.
Protection: Ensured all connections were tight, corrosion-resistant, and protected from moisture and soil contact to prevent future deterioration.
Verification: Performed continuity checks and functional tests to confirm proper grounding and correct breaker operation before re-energizing the system.

Result: safe, code-compliant grounding was re-established the same day, returning the HVAC system to reliable operation for the Matthews property.

Why proper HVAC grounding matters

Grounding is a critical safety feature. It provides a dedicated, low-resistance path that helps protective devices trip quickly during a fault. When a ground wire is damaged, you may encounter nuisance trips, tingling sensations near equipment, or increased risk of equipment damage. Restoring the ground ensures safer operation, reduces shock hazards, and aligns with electrical code requirements for residential systems in Matthews.

Common signs your ground wire may be damaged

Recent landscaping, digging, or hardscaping work near the outdoor HVAC unit
Visible nicks or cuts on wiring or conduit around the condenser
Intermittent breaker trips when the HVAC starts
Corrosion or loose bonding connections on the unit or disconnect
HVAC equipment behaving erratically after site work or storms

If you notice any of these issues at your Matthews home, it’s best to have a qualified electrician evaluate the system promptly.
