What Our Commercial HVAC Maintenance Includes



  • Filter Replacement

    We replace filters on a schedule based on building use, occupancy, and air quality needs. Clean filters protect equipment and maintain airflow.

  • Coil Cleaning

    Condenser and evaporator coils are cleaned to maintain heat transfer, reduce energy use, and prevent compressor strain.

  • Belt and Motor Inspection

    We inspect, adjust, and replace belts and check motor bearings and amperage on blowers and condenser fans.

  • Refrigerant System Checks

    We measure pressures and temperatures to confirm proper refrigerant charge and identify leaks early.

  • Gas Heat Section Service

    Commercial HVAC maintenance includes inspecting burners, igniters, heat exchangers, gas pressure, and venting on gas-fired equipment.

  • Electrical and Control Testing

    We tighten connections, test capacitors and contactors, and verify thermostats, sensors, and building controls operate correctly.

  • Condensate Drain Cleaning

    We clear drain lines and pans to prevent water damage and shutdowns.

  • Economizer Inspection

    We verify dampers, actuators, and sensors function properly to provide free cooling when conditions allow.

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

Maintenance Plans for Different Commercial Properties



  • Offices and Professional Buildings

    Consistent comfort supports productivity, and quarterly or semi-annual maintenance keeps systems ready for seasonal changes.

  • Retail Stores

    Customer comfort affects sales, and retail spaces with frequent door openings place extra load on equipment.

  • Restaurants

    Kitchens generate heat and grease, and make-up air units must work with exhaust systems. Restaurants often need more frequent filter changes and coil cleaning.

  • Medical and Dental Offices

    These facilities require reliable temperature control and clean air for patients and staff.

  • Warehouses and Industrial Spaces

    Unit heaters, rooftop units, and ventilation systems in large spaces need regular service to handle high demand.
