On arrival boiler was not operable. No water pressure in system and pilot was out. After looking over the boiler and the controls I advised the homeowner that the boiler system should be upgraded. I did not perform any maintenance service on the boiler because there are multiple issues. As a courtesy, I was able to get the pilot lit but this will not be a reliable heat source for the season. Outdated expansion tank, no automatic fill valve, no LWCO, purging valves are corroded. I provided homeowner with a written proposal to upgrade the system entirely based on age and condition for a reliable heat source this season. ***Waived diagnostic fee with signed proposal today***
