2 system a/c repair and preventative maintenance check complete. Changed filters. Found rusty drain pan and rusty evaporator coil upstairs. Upstairs blower motor controller is running weak. Installed a union on drain line and cleared line. Added chlorine tablets to condensate pump. Found weak voltage absorption system in basement system. Found low r22 levels in upstairs system. Due to age and condition of systems, recommend upgrading systems to more reliable, more efficient systems. Replaced upstairs blower motor controller, added leak sealer to upstairs system, recharged upstairs system, replaced downstairs voltage absorption system and installed hard start kits in both systems. Systems are cooling at this time. Customer signed up for Comfort Club Membership plan.
