Arrived onsite for issue with the heating. Homeowner stated second floor bedroom is heat even though thermostat is not calling for heat. Performed diagnostic and found a fault in the personal comfort control system. Homeowner elected to try the bandaid repair. There is a chance we will have to come back to perform a more detailed control repair if this does not fix the problem. More detailed repair may take time to drain a circuit and boiler and cut into piping. Performed repair. Had to also performed wire terminal service on the comfort controls due to faults in wiring. Upgrading serval of the wiring terminations. All systems working at this time. Homeowner will reach out if problem continues in the heating system.
