Luis 5-4-26 customer called in because heater not working second floor. We installed 2 floor ac unit month ago, I found pump not connected, and wiring not connected properly to turn off system. Corrected low volt safety wiring, and test operation, adjusted charge to increase sub cooling 454b total of 8 ounces, I tested pump, ok I run new vinyl tubing from pump to 2 in pvc drain pipe.

Dan 05/04/26 I arrived to the customers home to service their 14 yr old trane a/c system. . I checked the wiring connections and the voltages . I checked the indoor air filter . I Inspected the indoor coil and tested the primary drain pan with water and flushed the drain line and cleared. I Took indoor temp splits at the return and the supply and checked the blower motor condition and operation. I looked at the outdoor unit wiring connections and voltages . I inspected the outdoor components and checked my unit pressures by using super heat sub cool method. The system is currently operational but past normal life expectancy. Replacement of system is recommended in the near future.

Reviewed ac and ahu system replacement. Recorded all information.. discussed heat pump vs ac only replacement. There are 7 supply runs and 2 return runs in the space.

I arrived for 2 no a/c systems working . Both blowers run on the inside units. I started with the 2nd floor system in the attic . The filter is fine, the blower is running and we’re getting a call for 24 volts from the indoor to the AC from the thermostat outside . I have a call for my thermostat wire coming into the board for cooling outside from my y and c . I did find that I don’t have a call for 24 volts between my c and r . R will power the board. The system has good pressure, I checked all my low and high pressure switches. I jumped them off the board individually and found good. I went to the attic and found the wire was broken for the r going outside. I repaired the wire and replaced in the wire nut for the reds. Now I have a power light on the board. The a/c is back up and running for the 2nd floor . have 240 V power and I got 24 from the call for AC to the board . I’m highly recommending for the AC to be replaced in the near future. 1st floor system. 1st floor system

4/18/26 Dan I arrived for a mini split wall unit leaking water . I talked with the customer and the water was leaking from the mini pump Below the wall unit . We had just serviced the equipment Monday the 13th. They were having an issue with the 1st floor wall unit. I looked over the system and tested the fan speeds and tested cooling mode. I water tested the drain multiple times did find a small kink on the waterline outside at a wire tie connection where it was pinched. I removed the kink and cut the hose slightly shorter and begin water testing the drain, diverse tech pump is working and pumping better. It is a long drain run. No charge since we were just hear recall .
