Your HVAC System Is the Usual Suspect

When your electric bill jumps unexpectedly, the HVAC system deserves immediate suspicion. It's the largest single electricity consumer in most WNC homes, and a host of problems can cause it to draw significantly more power without obvious symptoms. Unlike a light left on or a space heater running, HVAC efficiency losses are invisible — you feel the same comfort (or think you do) while paying much more.

Quick Checks to Do Right Now

Check your air filter — a clogged filter makes the system work harder (5–15% efficiency loss). Verify thermostat settings haven't been changed accidentally. Make sure all vents are open and unblocked. Check that the outdoor condenser coil is clean and not blocked by debris. Compare your bill to the same month last year — was the weather significantly different? Duke Energy's website shows your monthly usage trend, which helps identify when the spike started.

Hidden HVAC Causes of High Bills

Refrigerant leak: Your system runs longer to compensate for reduced capacity, doubling runtime. Failing compressor: A compressor that's losing efficiency draws full power but delivers partial cooling. Stuck contactor: If the contactor welds shut, the outdoor unit runs continuously — even when the thermostat isn't calling for cooling. Defrost board malfunction (heat pumps): A heat pump stuck in defrost mode runs backup heat strips, which consume 3–5x more electricity than normal operation. Duct leaks: 20–40% of conditioned air escaping before reaching your rooms means the system runs proportionally longer.

Getting to the Bottom of It

If quick checks don't reveal the cause, schedule a professional diagnostic. Quality Comfort's technicians measure system performance — refrigerant pressures, amp draw, airflow, and duct leakage — to identify exactly what's driving your bill up. An HVAC energy audit provides the most comprehensive analysis. Often, the fix is straightforward and the savings recoup the service cost within a few months.
