A/c tune up in Snellville. System had a really dirty filter. Causing unit to ice up, drain pan had a lot of water and overflowing doing a little bit of water damage to the celling. Evaporator coil is clean, blower wheel is clean, and drain line is good. ( HOUSE IS A RENTAL PROPERTY ). Also found one of the supply ducts disconnect and completely opened allowing cold air into the attic. ( it’s fixed now). System is cooling at this time.
