I performed a single system heating maintenance on a gas 4 zone communicating system. I checked amps, capacitor, filter, drain, electrical, cleanliness, and safeties. Customer mentioned the drain was backing up in the bathtub. I investigated this issue, and I determined that it was only the tub that is clogged. The A/C drain is free flowing. Customer spoke about an automatic drip drain treatment machine. I put in a service estimate request for pricing. The outside unit is in good condition and free of debris build up on the coil. I gave the customer a price for total-c to help with his tub.
