HVAC System Maintenance: Tips for Cooling Season

With the warmer than usual New York winter, spring is just around the corner with summer following close behind. Making sure that your commercial HVAC system is ready to keep your buildings cool and energy efficient is essential and proper maintenance does that.

4 Commercial HVAC Cooling Season Tips

  1. Inspect and Change Air Filters
  2. Air filters are a vital component of any HVAC system by trapping dust, dirt, debris, etc. and helping to maintain healthy air quality. Clogged air filters hinder airflow and make your air conditioning work harder to achieve the desired temperature as well as run inefficiently. By inspecting and changing air filters regularly, you avoid overheating, higher than necessary energy costs, and system failures. How often you change air filters depends upon your particular HVAC system and the usage pattern for your building.

  3. Do a Thermostat Check
  4. Before hot weather arrives, your HVAC system’s thermostat should be checked. A malfunctioning or improperly set thermostat can lead to uneven cooling and short cycling. At the same time, check that you’re using optimized temperature settings that balance comfort with energy savings.

  5. Clean the Outdoor Condenser Unit
  6. The condenser unit is usually on the roof or attached to a wall and transfers indoor heat outdoors to facilitate interior cooling. Proper maintenance ensures cool air production. Lack of preventive care can lead to higher energy costs, greater system stress, and increased wear and tear. Keep the area around the exterior condenser free of debris and items that can block airflow. Ideally, the unit should have a minimum of three feet of clear space around the unit.

  7. Clean the Drip Pan and Condenser Lines
  8. Cooling air also removes moisture from it. The condenser lines and drip pan help to direct that water to a harmless area so it doesn’t pool and damage your HVAC equipment. Keeping the line clear and clean is essential. Clogged condenser lines not only lead to water backups but can develop mold, mildew, and even sometimes algae in the line.

    What Is Involved in HVAC Preventive Maintenance?

    When comes to commercial HVAC, the adage “an ounce of prevention is worth a pound of cure” is very true. A good maintenance plan also improves energy efficiency. Here’s what HVAC preventive maintenance commonly includes:

    • Duct system inspection
    • Air filter inspection and replacement
    • Ignition switch cleaning
    • Blower assembly inspection and cleaning
    • Safety control testing
    • Belt lubrication and replacement
    • Thermostat check
    • Drip pan, evaporator coil, and condenser line inspection and cleaning
    • Heat exchanger inspection
    • Fan motor and blade inspection and lubrication
    • Refrigerant level check
    • Condenser cabinet and coil inspection and cleaning
    • Compressor inspection
