HVAC Checklist – Monthly

Many modern HVAC systems are complex and require the skills of a trained professional. If your on-site maintenance staff is not fully familiar with HVAC systems, hire a professional before you are faced with a system failure or water management crisis.

We have included some steps you can take to to increase the life of your equipment and decrease the need for a trained professional; please read more to learn how:

  • Inspect your HVAC air filters monthly, or as recommended in the Operations and Maintenance manual. If you don’t know how to access the filters, refer to the manual for your specific unit.
  • When dust and debris are present, replace the filter with an identical filter as recommended by the manufacturer. If the filter is reusable, be sure it is completely clean and dry before reinstalling. Depending on its size, the equipment may have multiple filters that should be inspected or replaced.
  • Inspect all condensate drains and drain pans monthly, especially if your building must provide cooling most of the year. Refer to the maintenance book when inspecting drains and drain pans.
  • Check drain pans to insure they drain freely, are adequately sloped toward the outlets and that no standing water is present.
  • Make sure drain lines are clean and clear of obstructions.
  • If dirt, algae, or other contaminants are found, the drain line should be flushed and the drain pan carefully cleaned (pour a water-bleach solution down the drain line until it flows freely).
  • Inspect for signs of rust, which could indicate a water problem and need for prompt repair.
  • If the line drains to the outdoors, ensure that drainage travels away from the structure.
  • If the condensate drain is located on the roof, check that the drain is not clogged.
  • Rooftop drains should never drain directly onto the roof or over the side of the building.
