Live in an Area With Cottonwood? Here's What it Can Do to Your Cooling System.

Cottonwood trees are beautiful, but their fluffy, white, cotton-like seeds can cause problems. Those seeds can be drawn into your cooling system when it runs, potentially building up and causing the unit to work harder to pull in air. And that can cause your system to run more often and leave you with a higher utility bill.

Cleaning out the cotton-like seeds

You can clean out your air conditioner’s cottony build-up by first turning off the power to your unit. There should be a disconnect box located behind your AC on the exterior wall of your home. Once you’ve located the box, pull out the fuse or remove the disconnect. If you’re having trouble finding the disconnect box, you can turn off power at the main breaker in your home.

Once you have ensured that there is no electricity running to the air conditioner, use a hose to spray the fluffy seeds off the condenser blades. Spray the water at an angle so that it isn’t pushing the seeds any deeper into the unit. Once you have removed the build-up, shut the hose off and reconnect the power.

It’s a good idea to clean the air conditioner on a warm day so you can test the unit after you’ve removed the build-up. If you’re uncomfortable handling this kind of work, consider calling a heating and cooling professional.
