Very professional approach to service.

Yonis was very professional about the service. He took the time to explain everything to me and to answer my questions without appearing to need to get away fast to another appointment. I appreciated that. And, my compliments on what I think it is a good safety feature to send a message about the technician's arrival that includes a picture of the technician.

Finished installing duct transition, condensate line, and furnace flue piping. Pull vacuum on system down to 260 microns and recharged system with 3 lbs 14 oz of 410a. System operating with ideal pressures but high superheat due to space being so hot. TD is right at 20 degrees though.

Unit had been left off so there was no ice on the coil. I found the filter and evaporator coil were clean as well as the condenser coil. Unit has a txv metering device and was operating with 1-2 degrees subcooling and high superheat. I ended up adding 1lb 8oz of r410a refrigerant to achieve 10-12 degrees subcooling, 8 degrees superheat and 20+ degrees delta temperatures across the evaporator coil. Unit operating normal.

Upon arrival I went to thermostats and found both zones at setpoint 72, but humidity is in the mid 60s for both zones. Per Alex I shut off power to system and swapped thermostats from master bedroom and guest bedroom next to it. When I removed master Tstat I found large air gap where wires are fed, sealed gap with insulation so it doesn’t give false humidity readings, this Tstat uses temp sensor for temperature but Tstat itself reads humidity. Guest bedroom Tstat didn’t have a gap, insulation was already inside. Then I went to attic and reattached bypass duct. Calibrated bypass so customer doesn’t hear air pressure. Returned power to system and programmed each thermostat. Per Alex I turned off dehumidification for guest bedroom but left it on for master, and changed settings so dehumidifier doesn’t run with ac. Went to cubes in basement and found no faults or lockouts. Was asked to call Water Furnace regarding the E10 compressor monitor faults, 2 in prior service but 0 faults o

I replaced the txv in the attic at the air handler. I pressurized with nitrogen to check for leaks. I then vacuumed the system into a sub 500 micron vacuum and charged the unit to achieve normal superheat and subcooling and normal delta temperatures across the evaporator coil. Unit operating normal.

Upon arrival I was shown kitchen mini split AHU that was leaking water from front right corner, was also shown rust spot and very slow dripping from AHU in tv room. Found kitchen ahu drain was clear but tubing going into pvc was kinked upwards, not letting water drain at all. Removed cover on outside penetration, removed tube to make sure it was clear then tested drain and found it draining properly. Put tube back into pvc, made sure it wasn’t kinked and pipe went all of the way in. Tested drain and unit is operating normal. Found tv Room AHU dripping at lineset cover outside of AHU. Removed cover to find insulation torn and pipe frozen from condensation. Turned units to heat so pipe would thaw, cleaned up water and returned system to ac. We need to return to reinsulate these pipes behind the AHU. Need wall bracket or helper to do so.
