Work Performed Responded to no heat call. Diagnosed Gibson furnace and found hot surface ignitor (HSI) not functioning. Quoted client on HSI replacement; client chose universal HSI option. Did not have universal HSI on truck at time of visit. Will check stock and order if necessary. Discussed Comfort Club membership and maintenance; client declined at this time. Results Furnace is currently not operational until HSI is replaced. Full diagnostic and safety check will be completed with the HSI replacement. Recommendations Return visit required to replace HSI and complete diagnostic and safety inspection. Availability of part may be limited as it is the end of August and heating suppliers may not have stock on hand.
