Tech arrived at a 3 system tuneup. The Downstairs and master systems are warranty. All system blower areas and ducts were dirty. The drain lines were clear and bleach was poured. There was growth present in the supply plenum. The filters were relatively clean. The attic insulation was low. There are direct replacements for the currently installed comb-type AprilAire filter. The upstairs system - the condenser fan capacitor was out of tolerance. The Delta was high. The pressures indicated a malfunctioning TXV and low refrigerant. The rusty evaporator coil was leak searched and found to be leaking (refer to video). The customer was informed of recommendations today. He would like a phonecall from a Comfort Advisor about upgrading the Upstairs system to something more reliable with warranties behind it. Rob will give him a call tonight. The Upstairs system was left in the Off position to avoid further damages.
