Common Problems

Signs Your HVAC System Needs Repair

❌ Not Cooling or Heating

System runs but can't reach the set temperature? Refrigerant leak, dirty coil, or failed capacitor — all common, all fixable.

🔊 Unusual Sounds

Banging, rattling, squealing, or grinding indicate loose parts or worn components. Early repair prevents costlier failures.

⚡ Rising Energy Bills

A sudden spike in bills without a change in usage points to a component that's working overtime to compensate for a malfunction.

💨 Short Cycling

Turning on and off every few minutes instead of running full cycles? Short cycling damages equipment and should be addressed promptly.
