End-of-Season AC Service Checklist: What to Do Before You Shut It Down

Home | Blog | Published on September 1st, 2025

As summer winds down, many homeowners assume it’s too late for AC maintenance. The truth is, scheduling end-of-season service for your AC is one of the smartest steps you can take. At Creative Comfort Solutions, we often remind customers that taking care of your cooling system before it goes idle saves money, extends equipment life, and ensures your home is ready for next year’s heat. Instead of simply flipping the switch and forgetting about your AC, follow this checklist to protect your investment.

AC Check List

Change or Clean the Air Filter

Your air filter has been working overtime all summer, trapping dust, pollen, and other particles. Before you shut down your AC, replace or clean the filter. A fresh filter prevents dust buildup inside the system and keeps indoor air healthier. Starting next summer with a dirty filter means lower efficiency and unnecessary strain on the unit.

Clear Debris Around the Outdoor Unit

Fallen leaves, grass clippings, and dirt can easily accumulate around your outdoor condenser. This buildup restricts airflow and can cause corrosion if left unattended during the off-season. Take a few minutes to clear away any debris and trim back vegetation at least two feet from the unit. This simple step helps your system breathe easier when it kicks back on next year.

Inspect for Strange Noises or Odors

Even if your AC is still running, strange noises or musty odors should never be ignored. These could signal issues with the blower motor, evaporator coil, or mold growth inside the system. Scheduling a late-season inspection with Creative Comfort Solutions allows our technicians to address problems now, preventing costly breakdowns when summer returns.

Check the Thermostat

If you’ve been thinking about upgrading to a smart thermostat, the end of the season is the perfect time. A new thermostat gives you more control over your comfort, helps reduce energy bills, and integrates with your heating system for year-round benefits. The Creative Comfort Solutions team can install and program a thermostat that makes managing your indoor climate simple and efficient.

Schedule Professional Maintenance

Some homeowners believe AC maintenance is only worthwhile in spring, but end-of-season service is just as valuable. During a tune-up, our technicians clean coils, inspect refrigerant levels, check electrical components, and ensure all parts are in proper working order. This keeps your system in peak condition, reducing the chance of surprise failures when you need it again. Skipping this service could mean higher energy costs and shortened equipment lifespan.

Why It Pays Off Next Summer

Investing in end-of-season AC service prepares your system to run smoothly when warm weather returns. A well-maintained unit cools more effectively, consumes less energy, and lasts longer. Plus, you’ll avoid the rush of spring appointments when everyone else is scheduling their maintenance at once. By planning ahead now, you’ll enjoy peace of mind and reliable comfort.

Don’t fall for the myth that it’s too late for AC maintenance. Creative Comfort Solutions is here to help you protect your system and your budget with end-of-season maintenance. Call today to schedule your service and take the stress out of cooling your home next summer.
