Tech arrived at a 2 system tuneup. Both system had rusted coils, broken disconnects, and dirty blower wheels. The Downstairs system contactor was buzzing loudly. The upstairs system flame sensor was scorched. The capacitor was out of tolerance. The TXV was not working and it was very low on refrigerant. The customer was informed of recommendations today. Due to age, condition and price of repairs; it is recommended that the customer speak with a Comfort Advisor about upgrading to something more reliable with warranties behind it. The customer agreed and the meeting is set for Tuesday 3-5 12th. The upstairs system was left off at the panel breaker.
