DIY HVAC Maintenance Checklist for Bay Area Homeowners

MaintenanceMay 9, 20245 min readBy Jennifer Kim

Keep your heating and cooling system running smoothly with these simple maintenance tasks you can do yourself.

Monthly Tasks

Change or check your air filter. This is the single most important maintenance task. A dirty filter restricts airflow, reduces efficiency, and can damage your system. Check monthly and replace when dirty.

Clear around outdoor unit. Remove leaves, debris, and vegetation within 2 feet of your outdoor AC unit. This ensures proper airflow and prevents system strain.

Seasonal Tasks

Clean supply vents. Vacuum dust from registers and ensure furniture or drapes aren't blocking airflow.

Check thermostat batteries. Replace batteries annually to prevent unexpected failures.

Inspect visible ductwork. Look for disconnections, damage, or areas where air might be escaping.

Test your system. Before peak heating or cooling season, run your system to catch any issues early.

Annual Professional Maintenance

While DIY tasks help, professional maintenance is essential. A trained technician will:

  • Clean and inspect components you can't access
  • Check refrigerant levels
  • Test electrical connections
  • Verify safe operation
  • Catch small problems before they become big ones
  • Schedule Your Tune-Up

    Our maintenance plans include two annual tune-ups, priority scheduling, and repair discounts. Contact us to learn more.
