Commercial HVAC Repairs & Diagnostics
A tech on site, a real diagnosis, and a price before anyone turns a wrench. Self-performed commercial repair from High Point, NC across six southeastern states.
Covers the site visit, testing, and a written plan with pricing. Repairs are quoted separately and only start once you approve. Multi-site and contract pricing is available upon request.
The short answer
SBS-NC, LLC provides commercial AC services, HVAC repair, and diagnostics for facilities in Greensboro, Winston-Salem, and High Point, NC — the Piedmont Triad — and across North Carolina, South Carolina, Georgia, Florida, Alabama, and Tennessee. A $149 trip and diagnostics fee covers the technician visit, testing, and a written plan with pricing before any repair begins. We repair rooftop units, split systems, chillers, boilers, cooling towers, VRF systems, exhaust fans, and building controls — including equipment we didn't install. All work is self-performed by our own technicians, never subcontracted, and backed by labor and product warranties. Contract customers get 24/7 emergency dispatch. Call (336) 234-4979.
Four steps, no surprises.
You call
Tell us the site, the unit, and the symptom. We schedule — or dispatch immediately for contract customers.
We diagnose
A uniformed SBS-NC technician tests the system end to end — electrical, refrigerant, airflow, controls.
You approve
You get findings and a price in writing. Repair versus replace gets an honest recommendation, not a push.
We fix it
Repair completed, system verified under load, and the work documented for your records.
Control panel open on a wall-mount unit, meter out, cause found before anything gets replaced. This is what the $149 covers — a real diagnosis, not a guess and a parts order.

When it goes down after hours.
Contract customers reach a live dispatch line 24/7 and go to the front of the queue. A restaurant losing cooling on a Saturday night, a chiller tripping in a plant at 2 AM, a school with no heat Monday morning — those are the calls the program exists for.

Capacitors, contactors, belts, motors, and common controls ride with our techs, so most failures are fixed on the first trip.
