Performed cooling maintenance on a Trane XL18 Two stage AC system Cleared alerts from the thermostat Cleaned electronic air cleaner pre-filter and collection cells Put Condensate treatment in the evaporator coil drain pan to mitigate drain clogging issues like we experienced last winter Water is flowing properly from the Condensate drain to the floor drain Blower is clean Washed outdoor unit with water Refrigerant charge is in spec Capacitor and Amp draws in spec Found refrigerant lines touching each out inside the unit behind the removable grille Adjusted tubing positioning to eliminate rubbing This prevented an immenent loss of refrigerant at that contact point and also quieted down the vibration noise from the unit. System is clean and operating within factory specifications at this time.
