Came out for Home Care heating inspection on 2007 Lennox 80% Furnace (has 2016 Goodman AC attached). Upon arrival customer let me know they called us out because they were concerned about their flue pipe for upstairs furnace. Noticed it had tape over it so they wanted to call us out and be sure it was safe for use. Removed tape and found it was not attached properly. Adjusted double wall flue pipe then screwed in properly. Spoke about our Home Care plans and strongly recommended checking both furnaces today under our plan. Customer elected to go with Upstairs Furnace Inspection for now. Changed out 16x25x1 filter. Cleared condensate line. Emergency pan has float switch and emergency drain line going out to backyard, however, no wet switch. Recommend adding one for TE Standard Flood Protection. Also found wet spots on attic insulation where exposed suction line has been dripping over time. Recommend patching insulation on both systems' suction lines to prevent further water damage. Foun
