My unit is about 14 years old and the condensation/drip pan is rusting. I had a service contract tune-up and the technician said that with the old metal pans, once they rust and start clogging up the pipeline with small pieces of rust, they only option is to replace the entire unit!

Has anyone had a similar experience or have a solution for replacing just the pan?

The water is overflowing onto the air filter and soaking it.

Thanks.
