Performed Quality Assurance on Trane Gas Furnace/AC system. Ran system in Heating and Cooling modes. Tested the ez trap safety. Reviewed all programming on system. Reviewed installation with homeowner. She said the installers were very nice and polite. She said Jay/Jason was nice and he was doing a lot of the work. She said Nathan was very serious and dry. Completed checklist form in system. The new Furnace is shorter than the old one so there is not as much pitch on the condensate drain. Condensate is for the AC only since it is an 80% Furnace. Poured water through and it was draining. Leave a note for six month inspection to check the drain pipe to make sure it is draining correctly.
