Keeping your HVAC system in top shape during the hot summer months in East Tennessee is essential for comfort, energy efficiency, and extending the life of your equipment. With rising temperatures and increased usage, now is the time to ensure your system is running at peak performance. Use this ultimate summer HVAC maintenance checklist from Advanced Heat, AC & Plumbing to prepare your home for the season.

Why Summer HVAC Maintenance Matters

Summer places more demand on your HVAC system than any other time of the year. Neglecting routine maintenance can lead to:

  • Reduced cooling efficiency
  • Higher utility bills
  • Shortened system lifespan
  • Unexpected breakdowns
  • Poor indoor air quality

Proactive maintenance ensures your system operates smoothly when you need it most.

1. Replace or Clean Air Filters

Dirty or clogged air filters restrict airflow, forcing your HVAC system to work harder. This leads to higher energy usage and premature wear and tear. Make it a habit to check your filters monthly and replace or clean them every 30-60 days during heavy use periods.

Tip: If you have pets or allergies, consider changing filters more frequently.

2. Check Thermostat Settings

Ensure your thermostat is functioning correctly and set to your desired summer temperatures. For optimal efficiency, consider upgrading to a programmable or smart thermostat, which automatically adjusts settings based on your schedule.

3. Inspect and Clean Air Vents and Registers

Blocked or dirty vents and registers can hinder airflow and reduce system efficiency. Walk through your home and:

  • Remove dust and debris from all vents
  • Ensure nothing (like furniture or curtains) is blocking airflow
  • Make sure vents are open in rooms that need cooling

4. Clear Debris Around the Outdoor Unit

Your outdoor condenser unit needs ample airflow to operate effectively. Check the unit for leaves, grass clippings, or other debris and maintain at least 2 feet of clearance around it.

Also: Trim any shrubs or bushes growing too close to the unit.

5. Inspect Refrigerant Lines for Leaks

Low refrigerant levels can reduce your AC's cooling capacity and efficiency. If you notice your system struggling to cool or hear hissing sounds near the lines, it could be a leak.

Warning Signs:

  • Ice buildup on the refrigerant line
  • Warm air blowing from vents
  • Higher-than-usual energy bills

6. Clean the Evaporator and Condenser Coils

Dirt and grime can build up on your HVAC system’s coils, reducing their ability to absorb and release heat efficiently. Annual cleaning helps maintain peak performance.

Note: Coil cleaning is best handled by a professional during a seasonal tune-up.

7. Test Your System Early in the Season

Don't wait until the first 90-degree day to turn on your AC. Test your system early in the season to catch any issues before the peak heat arrives.

Listen for unusual noises, monitor the temperature, and check for uneven cooling throughout your home.

8. Check and Unclog the Condensate Drain Line

The condensate line carries moisture away from your AC. Over time, it can become clogged with algae or debris, leading to leaks or water damage.

DIY Tip: Flush the drain line with a mixture of bleach and water (1:1) every few months to keep it clear.

9. Inspect Ductwork for Leaks or Damage

Leaky ducts waste energy and can significantly reduce your cooling system’s efficiency. If you notice rooms that are harder to cool or a spike in utility bills, have your ducts inspected.
