Spring Maintenance Tasks

  1. Change the Air Filter
    Ensure your HVAC system runs efficiently by replacing the air filter. A clean filter improves air quality and reduces energy consumption. Check your filter every month, but change it at least every three months.

  2. Inspect and Clean the Condenser Coils
    Dust and debris can accumulate on the outdoor condenser coils. Gently clean them with a soft brush or a vacuum with a brush attachment to help your system operate efficiently.

    • Tip: Turn off the power to the unit before cleaning.

  3. Clear Drain Lines
    Check the condensate drain line for blockages. Use a wet/dry vacuum to clear any clogs. A clear drain line prevents water damage and maintains efficiency.

  4. Test the Thermostat
    Verify that the thermostat is working correctly. Consider upgrading to a programmable thermostat to save energy by automatically adjusting temperatures when you’re away from home.

Summer Maintenance Tasks

  1. Check Refrigerant Levels
    Low refrigerant levels can affect cooling efficiency. If you suspect a leak, contact a professional to recharge the system and repair any leaks.

  2. Inspect Ductwork for Leaks
    Inspect visible ductwork for any signs of wear or leaks. Sealing these leaks can improve your system’s efficiency by up to 20%.

    • Tip: Use mastic sealant or metal tape for sealing.

  3. Clean the Area Around the Outdoor Unit
    Maintain at least two feet of clear space around the outdoor unit. Trim any plants or remove debris to ensure proper airflow.

Fall Maintenance Tasks

  1. Schedule a Professional Tune-Up
    Before winter hits, schedule a professional inspection. A technician will check for potential issues and ensure your system is ready for the cold months ahead.

  2. Replace or Clean Air Filters
    Just like in spring, replace or clean your air filters to maintain good airflow and efficiency.

  3. Inspect Insulation on Ductwork
    Make sure the insulation around your ductwork is intact. Proper insulation helps keep your heating system efficient.

Winter Maintenance Tasks

  1. Check the Heating System
    Turn on your heating system to ensure it’s functioning properly. Listen for strange noises and check for any unusual smells.

  2. Seal Windows and Doors
    Inspect windows and doors for drafts. Use weather stripping or caulk to seal any gaps. This simple step can prevent heat loss and save on energy bills.

  3. Adjust Ceiling Fans
    If you have ceiling fans, adjust them to rotate clockwise to push warm air down during the winter months.

By following this seasonal maintenance checklist, you’ll ensure your HVAC system operates at peak efficiency, helping you save energy and keep your home comfortable year-round!
