AC Maintenance Mastery Unleash Your DIY Prowess


In the sweltering heat of summer, an efficiently functioning air conditioning system is a true lifeline. While professional AC repair and installation services are invaluable, there are several DIY tips that can help you maintain your unit and extend its lifespan. This article will guide you through essential maintenance tasks, ensuring optimal performance and cost-savings.

Filter Replacement

  1. Locate the air filter, typically behind a return air grill or in the air handler unit.
  2. Note the size and type of filter required for your system.
  3. Replace the filter every 1-3 months, or more frequently if you have pets or live in a dusty environment.
  4. Proper filter replacement improves indoor air quality and prevents system strain.

Outdoor Unit Care

  • Clear any debris, leaves, or vegetation from the area surrounding the outdoor unit, allowing for proper airflow.
  • Use a soft-bristle brush or a garden hose with a low-pressure setting to gently clean the condenser coils.
  • Straighten any bent fins on the condenser unit with a fin comb tool, available at most hardware stores.

Thermostat Optimization

Your thermostat is the brain of your HVAC system. Simple adjustments can maximize efficiency and savings:

  • Set the thermostat to a higher temperature when you’re away from home or sleeping.
  • Consider upgrading to a programmable or smart thermostat for automated temperature regulation.
  • Ensure your thermostat is located away from direct sunlight, drafts, or heat sources for accurate readings.

Professional Assistance

While DIY maintenance is essential, certain tasks require the expertise of a professional HVAC technician. Consider scheduling an annual tune-up with a trusted AC service provider like Mills Air to ensure your system is operating at peak performance and to identify any potential issues before they become major problems.

By implementing these DIY tips and seeking professional assistance when needed, you can enjoy a comfortable indoor environment while maximizing the lifespan and efficiency of your air conditioning system.
