Arrived onsite for maintenance for one gas fired boiler. Requested the customer turn on the thermostats up to heat and confirm operation of the boiler and each zone valve. Turned the boiler off and removed and cleaned all burners and wiped cleaner the burner compartment. Performed a visual inspection of all electrical and inspected all external water components such as the exp tank, fill valve, backflow preventer and the circulator pump. Observed noise from the Flue Damper and the Circulator Pump. Homeowner also mentioned he liked the previous circulator pump because it was larger. Recommend updating noisy components before next season. Completed combustion test. System working as it should.
