Met with Kelly who showed me to the mechanical room. I inspected a Weil-McLain gas boiler, I turned on the unit and observed it operate through its heating cycle, opened up the combustion chamber and tested its start up sequence procedure. Gas valve need replacement service, took a video to show the customer as there is a slight flame roll out issue occurring, explained the need for immediate attention. Overall the unit is in excellent condition with a burner cleaning service needed, worked up a price and discussed with Customer, the customer said that today is not a good day but that she will call to setup an appointment.
