This AC maintenance checklist will walk you through the common maintenance items that help extend the life of your unit. Keep cool and read our handy AC maintenance guide!

1. Replace the Air Filter

The air filter cleans the air that passes through the HVAC system. It traps dust, dirt, and other contaminants that could damage your AC unit and your health.

Generally, you should replace the air filter on your AC every three months. If you live in a dry, dusty climate or if you have pets, the filter may require more frequent changes.

2. Give it a Dust

Speaking of dust, you should regularly dust in and around your AC unit. Pay particular attention to the evaporator and condenser coils. Your AC runs less efficiently if the coils are dirty.

3. Inspect Drains

The condensate drain line takes the condensed water that accumulates near the AC’s evaporator coil and directs it out of the unit. Over time, gunk and algae can build up in the line and clog it. Clear it by following these AC maintenance tips:

  • Turn off the AC unit
  • Run a thin wire brush through the line
  • Flush out with a mix of warm water and vinegar
  • Sanitize with water and bleach

4. Clear the Motor and the Belt

Visually inspect the motor and the drive belt. If the belt appears damaged or if you hear unusual sounds coming from the unit, call an AC maintenance contractor to remediate the issue.

5. Look Out for Wiring Wear and Tear

Over time, the wiring can wear down. Faulty wiring can lead to a short circuit of the electrical components or fire. Because of the sensitive nature of electrical work, if you see something concerning, call in a pro to come and fix it.

6. Hire a Professional

This leads to the final point of this AC maintenance guide: call in a professional. The technicians like the ones found at can come in to perform a regular maintenance check-up. Professionals understand the intricate inner workings of AC units and will know the best steps for keeping yours running smoothly.
