1. Change or Clean Your Air Filters Monthly

A clogged filter restricts airflow, forcing your system to work harder and increasing energy use by 5–15%. Standard 1″ disposable filters should be swapped every 30 days, while pleated or reusable filters can often last 60–90 days, depending on dust loads and pet dander . To replace:

  1. Turn off power to your unit.
  2. Slide out the filter from the return-air duct.
  3. Insert a new filter (notch the airflow arrow toward the unit) or vacuum and wash a reusable filter.
  4. Restore power.

2. Keep the Outdoor Condenser Unit Clear

Leaves, grass clippings, and debris around the condenser reduce heat exchange and strain the compressor . Maintain at least 2 ft of clearance on all sides and 5 ft above the unit. Weekly:

  • Shut off power.
  • Use a soft brush or leaf blower to remove debris.
  • Hose down the fins gently from the inside out to avoid bending them .

3. Clean Evaporator & Condenser Coils Annually

Dirty coils insulate heat‑exchange surfaces, reducing efficiency by up to 25–35% and raising supply‑air temperatures by up to 2 °F. Once a year:

  1. Turn off power.
  2. Remove the service panel.
  3. Spray coils with a no‑rinse coil cleaner or a mild detergent solution.
  4. Rinse gently and let dry before restoring power.

4. Flush Condensate Drain Lines

Clogged drain lines cause water backups, mold growth, and potential water damage. Every 6 months:

  • Remove the access cap on the condensate pan.
  • Pour 1 cup of white vinegar, let sit for 30 minutes, then flush with water.
  • For stubborn clogs, attach a wet/dry vacuum to the line’s end and suction out blockages.

5. Inspect & Clean Blower Components

Dust and debris on the blower wheel and motor housing reduce airflow and can unbalance the blower, causing noise and wear. Annually:

  1. Turn off power and open the blower compartment.
  2. Use a soft brush and vacuum attachment to clean the blower blades and housing.
  3. Check motor mounts and belts for wear.

6. Ensure Vents & Registers Are Unobstructed

Blocked supply or return vents cause pressure imbalances, hot/cold spots, and reduced efficiency. Monthly:

  • Walk each room to confirm vents are free of furniture, curtains, or rugs.
  • Vacuum vent grilles and brush inside to remove dust.

7. Test Thermostat Accuracy & Upgrade if Needed

A miscalibrated thermostat leads to short‑cycling or overcooling. Quarterly:

  • Compare thermostat reading to a standalone thermometer placed next to it.
  • If off by more than 2 °F, recalibrate per the manufacturer’s instructions or replace the thermostat.
  • Consider installing a programmable or smart thermostat to save up to 10% on cooling costs through optimized set‑points.

8. Inspect Refrigerant Lines for Insulation & Leaks

Exposed refrigerant lines should be insulated to prevent energy loss. Annually:

  • Examine foam insulation on suction lines; replace if cracked or missing.
  • Look for oily spots or listen for hissing sounds—signs of a refrigerant leak.
  • While DIY repair isn’t recommended, early detection allows you to call a pro before the compressor is damaged .

9. Level the Outdoor Unit

Over time, the concrete pad under your condenser can settle, causing the unit to tilt. An unlevel unit strains the compressor and reduces oil circulation. Annually:

  • Check level with a carpenter’s level.
  • Lift and shim the pad with composite or concrete shims to restore level operation.

10. Schedule a Pre‑Season System Test

Even with diligent DIY care, an annual pre‑season check by a professional ensures everything is in optimal condition before heavy use. However, you can simulate many checks yourself in early spring:

  1. Turn on the AC for 15 minutes on a mild day to listen for unusual noises .
  2. Verify cool, steady airflow from all vents.
  3. Monitor for water leaks or odors.
  4. Clean or replace filters and clear debris around the condenser.
