What's the proper care for my original eqipment 1978 vintage 16,000 btu cruisair units? They don't have filters on them. Should they and if so what kind? Also how should I clean the coils?
Clean the coils with a powerful shop-vac. I saw a new filter media recently at a show that goes over the coils where there would normally be wire mesh, it looked like good stuff, I will try to find more about it and post it here when I do.
