Common Commercial HVAC Repair Problems



  • No Cooling or No Heating

    Loss of heating or cooling can result from compressor failures, refrigerant leaks, ignition problems, failed heat exchangers, or control failures.

  • Uneven Temperatures Across Zones

    Hot and cold spots in offices and retail spaces often point to damper problems, failed zone controls, duct issues, or units operating below capacity.

  • Poor Airflow

    Clogged filters, failed blower motors, broken belts, and duct restrictions reduce airflow and system performance.

  • Economizer Failures

    Stuck or failed economizers can let in too much outdoor air or prevent free cooling, increasing energy costs and causing comfort complaints.

  • Water Leaks and Drainage Problems

    Clogged condensate drains on rooftop units and indoor air handlers can cause ceiling damage and equipment shutdowns.

  • Control and Communication Faults

    Building automation errors, failed sensors, and wiring problems can cause equipment to run incorrectly or not at all.

If your home is consistently warmer or cooler than the setting, the thermostat may be miscalibrated, poorly located, or failing.
