Proper maintenance of your heating and cooling systems is crucial for ensuring efficient performance, prolonging their lifespan, and reducing energy costs. While professional service is recommended for major repairs and installations, there are several DIY tasks you can perform to keep your HVAC system in top condition. Here are some essential tips:

Air Filter Replacement

  1. Check your air filters monthly and replace them when they appear dirty or clogged.
  2. Disposable filters should be replaced every 1-3 months, while reusable filters can be cleaned and reused.
  3. A clean air filter improves indoor air quality and reduces strain on your HVAC system.

Outdoor Unit Maintenance

  1. Clear debris, leaves, and vegetation around the outdoor unit to ensure proper airflow.
  2. Use a soft brush or vacuum to gently remove dirt and debris from the condenser coils.
  3. Straighten any bent fins on the condenser coils to improve heat transfer efficiency.

Thermostat Calibration

  • Check your thermostat’s accuracy by comparing its reading to a separate thermometer.
  • If the thermostat is inaccurate, follow the manufacturer’s instructions to calibrate or replace it.
  • Consider upgrading to a programmable or smart thermostat for better energy efficiency.

Ductwork Inspection

  1. Inspect accessible ductwork for signs of leaks, damage, or debris buildup.
  2. Seal any visible leaks with approved duct sealant or mastic.
  3. Consider professional duct cleaning if there is significant buildup of dust or debris.
