Tech arrived at a warranty 2 system tuneup. Upon inspection, the capacitors were within specs. The condenser coils were hosed off to assist with air flow across the coils. The Deltas were within range. The side system was showing a code for high pressure lockout. The system was running in heating mode upon arrival and it was relatively warm outside. The filters were relatively clean. The drains were clear and bleach was poured. The UV on the main system was not functioning. The customer was informed of recommendations today. She will talk to her husband and call back in to schedule upgrades. The systems were functioning upon departure.
