Performed annual air conditioning maintenance. Cooler day. Gave unit a good bath, really needed it, coils starting to get dirty. Visual inspection of unit, electrical ok. Found corner of coil has been bent / damaged. Not sure what caused it most likely been that way since original install. Contactor ok. Dual capacitor 60-5 ok. Unit could be higher per code, 4 in above grade it might be 1in.so bottom of condenser pretty dirty.
