Ohio summers can bring steady heat, humidity, and the occasional heat wave—so making sure your air conditioner is ready is key to keeping your home cool and comfortable. Whether you’re relaxing indoors or escaping a muggy afternoon, a well-maintained AC system makes all the difference in the summer heat.

Use this comprehensive checklist to prep your unit before the season kicks into full gear.

✅ 1. Change the Air Filter

Changing your air filter is one of the easiest ways to boost your AC’s performance. A dirty filter can restrict airflow, cause uneven cooling, and reduce your indoor air quality. Check your filter monthly and replace it at least every 1–3 months, especially if you have pets or allergies.

✅ 2. Test Your Thermostat

Set your thermostat to cool and make sure it responds quickly and maintains the set temperature. If your system isn’t cooling efficiently, or if the display is unresponsive, it might be time for a new unit. Upgrading to a smart thermostat can also help you save on energy while staying comfortable.

✅ 3. Clean and Unblock Vents

Walk through your home to ensure that air vents are open, clean, and free from furniture or curtains. This improves airflow and helps your AC distribute cool air evenly throughout your home.

✅ 4. Tidy Up the Outdoor Unit

Your outdoor condenser works hard all summer. Make sure it has the airflow it needs. Remove leaves, branches, and debris from around the unit, and gently rinse the coils with a garden hose. Be sure the power is off before doing any cleaning.

✅ 5. Inspect the Condensate Drain Line

Your AC removes humidity from the air, and that moisture drains through a condensate line. If it’s clogged, it could back up and cause water damage. Check for standing water near your indoor unit or signs of leaks. When in doubt, schedule a professional to clear the line.

✅ 6. Check Refrigerant Line Insulation

Take a look at the refrigerant lines going from your outdoor unit into your home. These should be covered in intact insulation. If you see cracks, gaps, or missing insulation, it’s time for a quick repair to protect system efficiency.

✅ 7. Listen for Unusual Noises or Smells

Grinding, buzzing, or banging sounds—or musty odors—are not normal. These could be early signs of motor issues, mold, or other problems. It’s best to address them early before they get worse.

✅ 8. Schedule a Professional AC Tune-Up

Nothing beats a professional inspection.
