# Complete AC Maintenance Checklist for Bay Area Homeowners
Regular AC maintenance is crucial for keeping your system running efficiently, especially in the Bay Area where we experience unique climate challenges from coastal fog to inland heat waves.
Monthly Tasks
Check and Replace Air Filters The most important maintenance task is checking your air filter monthly. Bay Area homes, especially those near highways or in dusty areas, may need filter changes every 30 days during heavy use seasons.
Signs you need a new filter: - Visible dust buildup - Reduced airflow from vents - Higher energy bills - More dust in your home
Clear Area Around Outdoor Unit Keep at least 2 feet of clearance around your outdoor condenser unit. Remove leaves, debris, and trim back any vegetation that could restrict airflow.
Seasonal Tasks (Spring)
Schedule Professional Tune-Up Before the cooling season begins, have a professional technician: - Check refrigerant levels - Clean evaporator and condenser coils - Inspect electrical connections - Test thermostat accuracy - Lubricate moving parts
Clean Condensate Drain The condensate drain can become clogged with algae and mold, especially in Bay Area humidity. Pour a cup of bleach solution down the drain to prevent clogs.
Annual Tasks
Inspect Ductwork Have your ducts inspected for leaks, which can waste up to 30% of your cooling energy. This is especially important in older Bay Area homes with aging duct systems.
Check Insulation Ensure attic insulation is adequate. Bay Area temperature swings mean good insulation saves money year-round.
Bay Area-Specific Considerations
Coastal Areas Salt air can accelerate corrosion on outdoor units. Consider more frequent coil cleanings and rust-preventive treatments.
Inland Areas Higher dust levels require more frequent filter changes. Consider upgrading to MERV 11 or higher filters.
Wildfire Season Prep During fire season, check filters more frequently and consider adding air purification to protect indoor air quality.
When to Call a Professional
Contact an HVAC professional if you notice: - Unusual noises - Weak airflow - Warm air from vents - Ice on refrigerant lines - Unusual odors - Rapid cycling
Regular maintenance prevents 95% of breakdowns and can extend your system's life by 5-10 years. Schedule your maintenance today to stay comfortable all season.
