Received a call that the Coleman unit in the attic on the right hand side of the house was not cooling, upon arrival I found that the air filter was plugged solid. Removed the filter media and replaced it with the one that was on top of the air handler, I confirmed that we now have air flow and that the system is cooling properly. We need to get a new April air model 501 media filter for the model 5000 air cleaner.
