5 End-of-Summer AC Maintenance Tasks You Shouldn’t Skip
As summer in Wilmington winds down, your air conditioner has probably been working hard to keep you comfortable through the coastal heat and humidity. Before you switch over to heating season, taking time to give your AC a little TLC can make a big difference in its performance and longevity. At Fulford Heating & Cooling, we’ve been helping local homeowners keep their systems running smoothly for over 50 years — and we know that a few simple maintenance steps now can prevent costly repairs later. Here are five end-of-summer AC maintenance tasks you shouldn’t skip:
1. Replace or Clean Your Air Filter
Summer pollen, dust, and pet dander can clog your air filter fast — especially in humid climates like Wilmington. A dirty filter forces your AC to work harder, reduces airflow, and can lead to higher energy bills. Swapping in a fresh filter (or cleaning a reusable one) helps maintain good air quality and keeps your system running efficiently.
2. Check and Clean the Outdoor Unit
Over the summer, leaves, grass clippings, and coastal debris can accumulate around your outdoor condenser unit. This buildup can block airflow and strain your system. Clear away any debris, trim back plants at least 2 feet, and gently rinse the fins with a garden hose to keep everything breathing freely.
3. Inspect Your Drain Line
Your AC removes moisture from the air, and that water exits through a condensate drain line. Over time, algae or debris can clog this line, leading to water leaks and even indoor water damage. Flush the line with a mixture of warm water and vinegar to keep it clear.
4. Check Thermostat Settings
As the seasons change, it’s a good time to make sure your thermostat is set for maximum comfort and efficiency. If you have a programmable or smart thermostat, adjust the schedule to fit your fall routine. A quick battery check is also a good idea if your thermostat uses them.
5. Schedule a Professional End-of-Season Tune-Up
Even if your AC seems to be running fine, a professional inspection can catch small issues before they become big repairs. Our certified technicians at Fulford Heating & Cooling will check refrigerant levels, inspect electrical connections, test system performance, and make sure your unit is ready for next summer — or the switch to heating.
Why End-of-Summer Maintenance Matters
By taking care of your AC now, you can:
- Prevent costly breakdowns next cooling season
