HVAC Disconnect Replacement and Electrical Repair in Charlotte, NC
On May 8, 2026, our Charlotte team completed an electrical repair at the Dean Residence to resolve intermittent furnace shutdowns. Our licensed electricians, Theo Coetsee and Robert Sloan, identified failing pull-out HVAC disconnects at the furnace locations and replaced them with reliable, service-friendly switches. The result: steady, consistent power to the heating equipment and an end to random system outages.
If your furnace or air handler in Charlotte, NC is randomly turning off, a loose or aging pull-type disconnect could be the cause—especially in crawlspace or attic installations where vibration and temperature swings can loosen connections over time.
What We Found
The home’s master furnace had stopped working again, continuing a pattern of occasional shutdowns. Instead of standard service switches, the units had pull-out style disconnects at the equipment. These devices were coming loose, intermittently cutting power and forcing the furnaces to restart. High-efficiency HVAC systems are particularly sensitive to power interruptions, which can shorten component life and create nuisance lockouts.
Our Repair Process
- Performed safety checks and verified intermittent power loss at the furnace circuits.
- Removed the unreliable pull-out disconnects serving the equipment in the crawlspace.
- Installed properly rated, clearly labeled service switches to provide a secure, stable power connection.
- Inspected the attic furnace location and addressed any pull-out disconnects found in the same manner.
- Tested operation under load to confirm stable voltage and consistent system performance.
Replacing pull-type disconnects with fixed service switches improves reliability, makes servicing easier, and helps protect sensitive HVAC electronics from repeated hard power cycles.
Benefits for Charlotte Homeowners

Signs You May Need an HVAC Disconnect Upgrade

- Visible wear, looseness, or heat discoloration at the disconnect.
