2 system a/c repair and preventative maintenance and a new Comfort Club Membership contract. Replaced clogged filter, cleared the upstairs clogged drain and cleaned dirty condenser coil. Upstairs has no water safety devices that shut off system in case of water backup. Suggest to replaced both burnt/pitted main switch and add a compressor saver to both ac to help extend the life of the system. Both system are cooling at this time
