2 system checkup on carrier gas units. Both systems have original furnaces which are over 20 years old. Both have capacitors that out of range. Blowers and inducer draft motors are pulling high amps and the main system has bearing failure. Both blowers are dirty and neither system has flood prevention. Master bedroom thermostat is original old mercury style and should be replaced. Customer uses home warranty and denied any repairs. It's highly recommended to replace both and the ductwork as the big system handles the small.part of the house and the small system handles the part.
