As temperatures begin to climb in Monroe County and the Toledo area, it’s the perfect time to get your HVAC system ready for the summer heat. A little preparation now can help your system run more efficiently, keep your home comfortable, and prevent unexpected breakdowns when you need cooling the most. Here are a few simple, practical steps to help you get started.

Start by Checking Your Air Filter

After a long winter, your air filter may be full of dust and debris. Replacing it is one of the easiest ways to improve airflow and keep your cooling system running smoothly. A clean filter helps your AC use less energy and keeps your indoor air fresher.

Schedule a Professional Tune-Up

A spring or early-summer tune-up ensures your air conditioner is ready for the season ahead. During a maintenance visit, a technician will check refrigerant levels, clean coils, tighten connections, and make sure everything is operating efficiently. This small investment can help prevent costly repairs later on—and keep your home cool all summer.

Clear Around Your Outdoor Unit

Your outdoor AC unit needs good airflow to work properly. Take a few minutes to remove leaves, branches, or debris from around the unit, and make sure there’s at least two feet of space on all sides. This helps your system breathe easier and cool more effectively.

Optimize Your Thermostat Settings

Setting your thermostat to around 76–78°F when you’re home is a sweet spot for comfort and efficiency. If you have a programmable or smart thermostat, set it to raise the temperature when you’re away and lower it before you return. This helps reduce energy use without sacrificing comfort.

Make Sure Vents Are Open and Unblocked

Blocked vents force your system to work harder than necessary. Walk through your home and make sure vents and registers aren’t blocked by furniture, rugs, or curtains. Good airflow is essential for even cooling.

Check Ceiling Fans and Window Treatments

Set your ceiling fans to rotate counterclockwise to push cool air downward. Closing blinds or curtains during the hottest part of the day also helps keep heat out, giving your AC a little break.

Preparing your HVAC system for the warmer months doesn’t take long, but the payoff is worth it—lower energy bills, fewer surprises, and a cooler, more comfortable home.

This is the greatest company! They are efficient, clean and very courteous! They always call ahead of your appointment time . They come ONTIME , every time. They replaced my furnace filter, water filter for the humidifier and did the annual maintenance on the furnace. I purchased the annual maintenance service as well. The entire bill was just over $200. My air conditioner service in the spring will cost me nothing. I have been with Home Comfort for many years. I live in the Legacy Estates subdivision in Temperance Mi. Call them . You can’t go wrong. You won’t overpay for quality service.

Mine was a boiler cleaning for the upcoming winter season. Jeremy could not have been more thorough and a very nice young man. I’ve been with Complete Home Comfort for quite a while now. I would never go anywhere else.
