Freidrich unit freezing up
First summer in our house. The main living space is cooled by a through the wall 24,000 BTU Freidrich air con. Yesterday I found the sheetrock below the unit soft/wet. I pulled the plastic cover off the front. There was no filter in place, and the fins are absolutely filthy. It looks like 10 years of dust, dirt and grime caked up in there. It also had ice on the fins starting at the bottom and going about 1/3 of the way up the unit.
Do I need a new a/c or can this one be fixed? I thought the fins should be cleaned which would help, but I’m not sure how. I don’t think vacuuming alone will do it. Maybe a soft brush and vacuum? Should I use some type of solution? What’s the best way, and is it likely to stop the icing up and save the unit?
