Tech arrived at a membership tune-up. Upon inspection the capacitor was within specs. The contactor was in working condition. The condenser coils were hosed off to assist with air flow across the coils. The Delta was within range. The filter was dirty. The drain was clear. The customer was informed of recommendations today. She decided to upgrade to an AprilAire filter. This item was installed and functional today. The system was functioning upon departure. She would like to be emailed a copy of the Titanium Membership information.
