2016 3t gas attic horizontal. Filter replaced and dated. Drain line flowing. Blower clean. Evaporator coil clean. Electrical connections tight. Reinforced a supply ducts with proper tape. Condenser coil washed with chemical cleaner. Amps, volts and refrigerant charge withing tolerance. System functional. Secondary main system was installed by a company in Burleson TX shortly after our CA appointment in November of 2024. Homeowner canceled his long standing membership on that unit after install. I politely explained that if I put my hands on it that'll potentially void any warranties he holds with the other company that services the brand new system.
