Upon arrival, I attempted to start the oil-fired furnace to assess its operation prior to performing any service. The furnace did not start, though power was verified at the service switch. The customer mentioned that there had been a short in the stair switch at some point in the past, and that switch has since been removed. Upon inspection, I found that there is no Firomatic safety shutoff valve installed at the burner. This component is required to stop oil flow in the event of a fire and is an important safety device. I reviewed the recommended repairs and service costs with the customer. The customer has chosen to postpone the work at this time. No repairs or maintenance were performed today. Estimates for the recommended work will be sent to the customer via email. Recommendation: Installation of a Firomatic valve and completion of the furnace service are highly recommended for safe and reliable operation.
