End-of-Summer AC Maintenance Tips for Whittier Homeowners

With summer winding down, you might think you’re just about done with your AC for the year. However, taking the time for a little late summer AC maintenance in Whittier, CA, can ensure reliable performance at the start of the next cooling season. Here are some steps you can take to improve your system’s cooling, efficiency, and longevity.


Schedule a Tune-Up if You Haven’t Already

Most homeowners schedule AC tune-ups in the spring or early summer. However, if you didn’t get one yet, you shouldn’t leave it until next year. There could be a variety of potential issues with your AC that will only get worse over time. A professional tune-up will optimize performance for the rest of the season and help you avoid costly repairs.


Remove Any Debris Around the Outside Unit

Debris around the outside unit can cause serious damage between now and next summer. Any sticks and overgrown foliage can damage components and get jammed into internal parts. There are also moisture and corrosion issues related to the buildup of leaves and other organic matter. Clear out the area thoroughly to protect your AC.


Clean the Drain Line

The drain line plays a key role in removing moisture that builds up in the interior unit. However, this constant moisture also poses a risk of mold and algae. Before the season ends, take a look to ensure there isn’t any growth that could get out of hand. Clean the drain line with a simple mixture of water and vinegar to stop any organic growth.


Check for Any Signs of Damage

You should also take a look at your system for potential signs of damage before the season ends. Is it making strange grinding or clunking noises? Can you see any rust or corrosion on the outdoor unit? Take action on these issues now to avoid worse problems next year.
