HVAC Repair Winston-Salem | AC & Heating Service | HVAC Concepts LLC

Yes, that's a common symptom of a refrigerant leak, especially during our hot Piedmont summers. Low refrigerant prevents your system from absorbing heat effectively. Our technicians use electronic leak detectors to find the source quickly and can often repair the leak and recharge your system to restore full cooling power, improving efficiency and preventing further damage.

Other Winston-Salem homes often have aging thermostats that can malfunction due to wiring issues, dust accumulation, or simply old age. An inaccurate or unresponsive thermostat wastes energy and compromises comfort. We can diagnose if it's a wiring problem, a faulty sensor, or if it's time for an upgrade to a modern, programmable, or smart thermostat for better control and energy savings.

During peak summer, the most frequent emergency is a complete system shutdown often caused by a combination of issues like a severe refrigerant leak tripping a safety switch or a failed capacitor from strain. We offer 24/7 emergency service for these critical situations to get your cooling restored quickly, diagnose the root cause, and provide a lasting repair to prevent future breakdowns.
