I got a 10 year parts and labor for free. You have to be a authorized Trane dealer to offer the 10 year warranty though. To be a authorized Train dealer you have to attend their school a few times a year, if I'm right. Heating & Air conditioning are important mechanicals in a home,and the company that installed my system has been around and a Union Shop for over 80 years,I trust them. My dad worked for them when he was a Union Plumber. The Sheetmetal, Plumbers and Labors on the job were all Union, They have that $30 an hour union pride that non union workers don't have, that money makes a difference in a mans attitude toward his work, and it shows up in their work also. No fucking wires hanging or pipes out of plumb, or I'll be back tommorrow and finish it and then never show up. The sheetmetal work is just beautiful, I asked for high,low return registers in every room, a heating register under every window, all ducts have dampers. Fresh outside air duct had to be cut through the side of the house and connected to the return trunk line. I am happy, I can hang meat in the house if I wanted to, and no cycling either. Honeywell Deluxe Programmable Multistage Thermostat with outside temp unit is nice too. There is alot of metal work in this job. The Trane electronic air filter is a great product too. A race system she be.
