Seasonal HVAC Maintenance Checklist for Bay Area Homeowners

05 / 15 / 2025

The Bay Area’s mild climate doesn’t mean you don’t need seasonal HVAC maintenance. Regular upkeep keeps your system running efficiently, extends its lifespan, and makes sure your home is comfortable all year. Here’s a seasonal checklist to keep your HVAC system in peak condition.

Spring and Summer Maintenance

As temperatures rise, your cooling system will be working harder. Prepare it for the season with these tasks:

  1. Replace Air Filters: Change filters every 1-3 months to keep airflow efficient.
  2. Clean Vents and Registers: Remove dust and dirt to ensure proper airflow throughout your home.
  3. Inspect the Outdoor Unit: Clear out debris like leaves and dirt around the condenser. Make sure to give at least two feet of clearance for optimal airflow.
  4. Check the Thermostat: Test your thermostat settings to ensure it’s cooling effectively. Think about upgrading to a smart thermostat to cut energy costs.
  5. Schedule a Professional Tune-Up: Have a technician inspect the refrigerant levels, ductwork, and overall system performance.

Fall and Winter Maintenance

When temperatures drop, it’s time to focus on heating. Use this checklist to prepare for cooler months:

  1. Replace Filters Again: Clean filters are a year-round necessity and are just as important for heating as they are for cooling.
  2. Test the Heater: Test your heating system early in the season to ensure it’s working properly.
  3. Inspect the Furnace: Check for strange smells or noises and ensure the burner flames are blue, and not yellow.
  4. Seal Drafts: Inspect your windows and doors for leaks to prevent heat loss and reduce strain on your HVAC system.
  5. Clean Air Ducts: Clear ducts of any blockages to get optimal airflow and efficiency.
  6. Schedule a Heating Tune-Up: Professional maintenance services will be able to identify and fix issues before the coldest months arrive. Let Peterson Mechanical help you with the best residential HVAC services in the Bay Area
