Arrived on site to perform an annual tune up on a propane boiler. After our initial inspection, we noticed a hyvent was leaking so we provided an estimate for the tune up and replacing the hyvent. Both were accepted. We then performed the tune up on the propane boiler. The tune up included inspecting flame sensor and igniter. We found that the igniter was visibly worn and also tested at above 110ohms. This indicates a failing or weak igniter and should be replaced. We got approval so we swapped it out. We then performed a combustion analysis, a gas pressure test and checked for CO leaks to verify system is operating properly. Combustion analysis and gas pressure was good. System is operating properly at this time. Due to the age of boiler, we recommend starting to think about replacing it in the near future. Thank you for your business!
