Summer Heatwave? Tips to Keep Your AC Running Smoothly in Kentucky

July 9, 2025

When the Kentucky heat hits full force in the heart of summer, your AC becomes more than just a comfort—it’s a necessity. To help you stay cool and avoid mid-season breakdowns, we’ve put together a few essential tips to ensure your air conditioning system runs at peak performance during the hottest months.

Keep Airflow Clear and Unrestricted

One of the easiest ways to improve your AC’s performance is by maintaining proper airflow. Start by checking your vents—make sure they’re open and unblocked by furniture, curtains, or rugs. Clogged or dirty air filters are another common culprit that can restrict airflow and cause your system to work harder than necessary. We recommend checking your filters monthly and replacing them regularly during high-use periods.

Seal Air Leaks and Insulate

When cool air escapes through poorly sealed windows, doors, or attic spaces, your AC has to run longer to keep up. Sealing cracks around window frames and weatherstripping doors can make a big difference in energy efficiency. Additionally, make sure your attic and ductwork are properly insulated. Good insulation helps maintain a consistent indoor temperature and reduces the overall strain on your system.

Use Fans to Support Cooling

Ceiling or oscillating fans don’t actually lower the temperature, but they do help circulate cool air more evenly throughout your home. Using fans in conjunction with your AC allows you to raise the thermostat a couple of degrees without sacrificing comfort—helping to lower energy use and extend your system’s life.

Keep Your Outdoor Unit Clean

Your outdoor condenser unit needs plenty of breathing room. Overgrown vegetation, debris, or even a buildup of grass clippings can reduce its ability to release heat. Take time to clear a two-foot radius around the unit and check that the coils are clean and undamaged.

Schedule Regular Maintenance

Routine professional maintenance is one of the best ways to keep your AC running efficiently all summer. A thorough inspection catches minor issues before they turn into major problems and ensures your system is properly tuned for the season.
