What Kind of Annual Maintenance Should I Perform on My Air Conditioner?

AC annual maintenance - Midwest Appliance Parts Co, Inc

1. Replace or Clean the Air Filter

One of the simplest yet most important tasks is replacing or cleaning the air filter. Over time, filters collect dust and debris, restricting airflow and reducing efficiency.

  • When: Check filters monthly and replace them at least every 3 months, or sooner in high-usage months.
  • Where to Buy: You can find OEM air filters that fit your specific system at Midwest Appliance Parts.

2. Clean the Condenser Coils

The outdoor condenser coils collect dirt, debris, and even leaves, which can impact your unit’s ability to cool effectively.

  • What to Do:
    • Turn off the system.
    • Use a garden hose (low pressure) to rinse off debris gently.
    • Avoid damaging the fins.
  • For specialized parts like coil cleaner spray, Midwest Appliance Parts has you covered.

3. Inspect and Clear the Condensate Drain

Your air conditioner removes humidity from your home, which flows into a condensate drain. A clogged drain can cause water damage or reduce system efficiency.

  • Steps:
    • Locate the drain pipe and ensure it’s free of blockages.
    • Use a wet-dry vacuum to clear out buildup if needed.

4. Check and Tighten Electrical Connections

Loose connections can be hazardous and affect your AC’s performance. During annual maintenance, it’s a good idea to inspect:

  • Wiring,
  • Terminals, and
  • Electrical components.

If you notice any wear, Midwest Appliance Parts has a wide selection of authentic OEM parts for electrical repairs.


5. Lubricate Moving Parts

Your air conditioner has several moving components like fans and motors. Proper lubrication reduces friction and prevents excess wear. If parts are worn or require replacement, be sure to order only OEM parts to guarantee reliability.


6. Inspect the Thermostat

Make sure your thermostat is working correctly and calibrated properly. For modern systems, consider upgrading to a programmable thermostat to improve energy efficiency.
