What to do About a Rusty Air Conditioner

October 1, 2019

A rusty air conditioner shouldn’t be ignored. If you live in a coastal area or a place where there’s a lot of humidity, check your AC unit. Salt and damp air can cling to your equipment and cause rust to form. Here’s what you need to do about the rust and why you should act quickly to remove it.

Check the Warranty First

Newer units may have a warranty that mentions rust and rust removal. Read your documents carefully to see if removing the rust yourself will invalidate the equipment warranty. If the system was designed to avoid becoming rusty, then you may have recourse through the manufacturer. Your local dealer will be able to tell you more about fixing the problem.

Request a Maintenance Visit

Rust knows no bounds. It can form on the outside of air conditioners, and it can cover the inside, too. Once inside, it will begin to eat away at the components. This is cause for alarm, because once it enters the interior of the system, you may have to replace the whole unit. Rust can permanently damage coils and parts deep inside the system.

The only way to know how far the rust has infiltrated is to have a professional take a look. Ken Parker Service, Inc. has a team of qualified NATE-certified technicians who can assist you. Our seasonal maintenance services can help you prevent rust from building up on your compressor.

Clean Away the Rust

When rust on the outside of the unit is caught in the early stages, it can be removed easily. Using a nylon brush, degreasing solution, and fine-grit sandpaper, you can get rid of it. Protecting the interior components when cleaning the equipment is important. After removing the rust, seal the surface with a rust-proof primer and a rust-proof paint.
