A commercial rooftop heating system may fail because of ignition problems, damaged heating components, gas supply issues, control failures, or airflow restrictions.Strange Noises or Vibrations
Grinding, rattling, banging, or squealing sounds should not be ignored. These noises can indicate worn bearings, loose components, damaged belts, failing motors, or other mechanical issues.Frequent Cycling
A rooftop unit that turns on and off repeatedly may be experiencing airflow problems, control issues, thermostat malfunctions, electrical faults, or equipment sizing concerns.Rising Energy Bills
