Special order toilet replacement
I operated the unit in high fire heat mode. I calculated airflow to be 1,800 cfm. The temperature rise is within comfort range and matches printed data. Gas pressure to the burners was increased from 3.0 to 3.5iwc. I checked the igniter and flame sensor. I checked the electrical wiring and electrical systems, all are within specification. The unit operates normal in heating mode. Customer signed up for a service membership today. The amount the customer paid on the invoice is for the duct cleaning and dryer vent cleaning. I called Donna and she will call the customer to schedule.
Completed boiler maintenance. All wired connections are tight , No leaks in piping , no blockages in flu venting , bled all the radiators, circulator is pulling inline with amps and operating. Costumer has heat pump but it is not on the service contract . I informed him and let him know it would be an additional fee and he said do not worry about it .

On arrival removed gas valve and installed an other gas valve .,tested unit operation.system operating normal
I recovered the charge. Removed the compressor and filter drier. Replaced both and used dry nitrogen to pressurize the system to check for leaks. It held 250psi. I then flushed the line set with nitrogen. I also put acid away in the new compressor. I pulled into a deep vacuum and charged with 7lbs 10oz of r410a refrigerant. I checked temperature rise and the unit is operating normal.
Upon arrival I was told that heat wasnâ€™t working on main floor. Went to package unit and found no LEDs on display. Also found top floor system had faulted on water flow because systems use the same flow center. Checked voltage and found no low volts. Removed fused disconnect to find 60amp fuse had blown. Replaced with new and tested systems. No additional problems found and units operating normal.
