End-of-Summer AC Maintenance Checklist for Homeowners in Orlando, FL

September 15, 2025

After months of running your AC nearly nonstop in Orlando, FL, your system deserves a little TLC. With Florida’s long cooling season, late summer is the perfect time to do an end-of-summer AC maintenance checkup. Use this checklist to help maintain comfort, efficiency and peace of mind as you head into the transitional months.

Clear Debris Around the Outdoor Condenser

Over the summer, it’s common for leaves, twigs and grass clippings to build up around your outdoor condenser. These blockages can restrict airflow and make your system work harder than necessary. Trim back nearby plants and maintain at least 2–3 feet of clearance around the unit. This allows for proper ventilation.

Check and Replace the Air Filter

A clogged air filter can reduce efficiency and compromise indoor air quality. It’s one of the simplest yet most impactful maintenance tasks you can do. During peak use months in Orlando, check your filter monthly and replace it if it looks dirty. This supports smoother airflow and a healthier home environment.

Inspect the Condensate Line

Your AC system removes humidity from your home, and the resulting moisture drains through a condensate line. Check this PVC pipe—typically located near the condenser—to ensure it’s draining freely. If water is pooling or the pipe appears clogged, it could shut down your system until it’s cleared.

Listen for Unusual Sounds or Smells

Turn your system on and listen carefully. Rattling, buzzing or grinding noises can point to loose components or electrical problems. Likewise, musty or burning odors may signal moisture buildup or wiring issues. If you notice anything unusual, it’s best to call in a professional to schedule repairs before it worsens.

Schedule Preventive End-of-Summer AC Maintenance with a Pro

Even if everything appears to be working fine, it is still a good idea to schedule preventive maintenance. This can help catch small issues before they turn into big repairs. A typical visit includes:

Inspecting and cleaning condenser coils
Checking refrigerant levels and electrical connections
Flushing the condensate line
Testing thermostat accuracy
Lubricating moving parts
Measuring airflow and inspecting ductwork for leaks
