Will try this. Fins are definitely visibly dirty, not filthy but I can see a thin layer of stuff on them but there are a lot of bent up fins, too. What tool would yall recommend to straighten them out or just call someone to do it and pay them?

a coil brush/rake about $8 at supply house it just some stiff wires laid out like a paint brush with a handle you run up and down the fins to straighten them out youll have to disassemble whatever type of material the unit has protecting the coil to do it its not hard just a few dozen screws usually
