I held an electrical license for years before focusing on HVAC. That background means I understand the electrical side of your HVAC system in a way most technicians do not. When a capacitor fails, a contactor burns out, or your disconnect box is unsafe, we handle it right — to code, with the correct parts.
HVAC Electrical Services
- Capacitor replacement (start and run capacitors)
- Contactor replacement (the heavy-duty switch that starts your compressor)
- Disconnect box inspection, repair, and replacement
- Surge protector installation for outdoor condenser units
- Blower motor and condenser fan motor electrical diagnosis

- Low-voltage wiring (24V thermostat wiring)
- High-voltage wiring at the air handler or furnace
- Ground fault and short circuit diagnosis
- Breaker trip investigation (HVAC circuits)
Safety & Code Compliance
- Disconnect box within sight of outdoor unit (NEC requirement)
- Proper breaker sizing for equipment amperage draw
- Wire gauge verification (undersized wire is a fire hazard)
- Carbon monoxide detector placement recommendations
- Heat exchanger crack inspection (CO risk in gas furnaces)
- Combustion air and flue venting safety check
- Condensate drain safety switch (prevents water damage)
Surge Protection for HVAC Equipment
Oklahoma has some of the worst lightning and power surge activity in the country. A direct or near-direct lightning strike can kill your compressor, control board, and variable-speed motors in an instant. We install dedicated surge protectors at the outdoor condenser unit. They are not expensive — typically $150–$200 installed — and they can save a $4,000 compressor replacement.

Frequently Asked Questions
My AC stopped working — could it be electrical?
Yes, very often. Capacitors and contactors are among the most common AC failures. A failed capacitor means the compressor or fan motor cannot start. A burned contactor means the compressor does not get power at all. Both are straightforward repairs. We bring common capacitors and contactors on every service call.
My breaker keeps tripping when the AC runs — what is wrong?
A breaker that trips repeatedly is telling you something. It could be an oversized or failing breaker, a refrigerant issue causing the compressor to draw high current, a failing compressor winding, or a wiring problem. We diagnose the actual cause rather than just resetting the breaker.
Do you recommend surge protectors for HVAC?
Strongly, yes — especially in central Oklahoma. We see surge-damaged compressors and control boards after every major storm season. A dedicated HVAC surge protector at the condenser unit is one of the best protection investments you can make.
Is HVAC electrical work safe for a homeowner to attempt?
Low-voltage thermostat wiring (24V) is relatively safe. High-voltage work — capacitors, contactors, disconnect boxes, breaker panels — is not. Capacitors hold a charge even with the power off and can cause serious injury. We handle the high-voltage side.
