Performed annual heating maintenance, rheem split system, gas furnace attic, with original grey flex ducts in bad shape. See pictures, showed client the pictures. Tested system. System operational, went through system visual inspection ok. Tested parts. Blower capacitor 7.5@7. Hot surface ignitor 115 ohms keep an eye on it, starting to climb if gets much higher might want to replace before it fails. See attached estimate. Cleaned burners and flame sensor. Control board ok, tight wires no loose connections, no burn marks on board at this time. Filter 20-25-1 in hallway and a 5†16-25 merv 11 in the unit in the attic, removed for better airflow looks to either have been installed or suppose to have been changed by 2009. Only need one filter in system. Tested system safety features. System operational at this time. Removed tape on door safety switch, so that it isn’t bypassed anymore. Changed filter for client.
