Arrived on site to troubleshoot a no heat. The furnace is a 1987 Trane natural draft furnace with a compromised heat exchanger. The pilot light was lit but the thermostat wouldn’t respond. Thermostat is also extremely old and failing, we replaced batteries and attempted to test the system again and the unit turned over and began heating again. We have failing motors, capacitors out of spec, breached heat exchanger, improper drains, improper flues and an r22 AC. Clients did say this is their forever home and would like somebody out to discuss replacement tomorrow after 3pm. They do currently have heat, but there is major work recommended to restore the system. We collected payment via mobile capture (check). Client want to sign up for Homecare but expressed interest in doing so tomorrow once the comfort consultation is in progress. Call complete pending tomorrows follow up.
