Upon arrival I went to system and pumped down refrigerant into HeatPump. Once refrigerant was removed from lines and AHU I removed old txv and installed new one. Made sure seals were correct and connection was tight. Pressurized System with 400psi of nitrogen and held. No leaks found. Put sensing bulb into place and removed nitrogen. Vacuumed system down to 500micron and held. No leaks found, vacuum held. Opened up valves and let system pressures stabilize. Returned power to unit and ran ac. Superheat 8, Subcool 9, delta t at Evap 23. Let system satisfy thermostat. Unit operating normal. Customer also asked me to take a look at High fan speeds whenever heat is running for first floor system. Found differential settings were not enabled and aux heat lockout was not enabled either, finally system was setup for finish on high stage heat. Enabled aux heat lockout for 40 degrees. Also removed finish on high stage heat so unit will run more efficiently. Both units are operating normal.

Upon arrival customer mentioned that he doesn’t think top floor ac unit is working and wanted verification if bottom floor unit was working properly. During diagnostics I called for ac for top floor system. Found indoor unit running but outdoor unit now. System tripped on pressure fault. Reset fault and put on gauges to find No Superheat and No Subcooling. Opened up AHU panels and adjusted TXV but I’m not seeing any difference in refrigerant pressures. TXV needs to be replaced. Then went to main floor system and called for ac. Put gauges on system and checked operation. Found normal Superheat, normal subcool, and normal delta air temps. Unit seems to be operating normally. Need to return to replace top floor txv. Part order form has been uploaded. Office please follow up with customer on return to replace txv.

Unit #1, the inverter system began operating on cooling after being reset. The charge was 12oz low but no leaks detected. I cycled the unit several times from test mode and from the thermostat and it’s op normal. The only fault code registered is blower limit, but all dipswitch settings are correct. If problem reoccurs a technician needs to come out when the6 can call tech support. Unit #2 was off at the outdoor unit because of multiple low pressure trips. I went into the attic and found the air handler was set for y1 only which is low cool. I jumpered y1 and y2 so that the blower will move twice the airflow and then checked the charge, unit operating normal. I called service manager to let them know what I had found and done.

Installed the gateway device and paired it to the main levels thermostat. Customer has to finish the setup and registration process. In regards to the airflow, I trimmed the airflow by 10% using the settings in the Comfort Net menu of the thermostat. The outdoor temperature was displayed correctly. The upstairs unit uses a different thermostat that is already connected to WiFi.
