I want to acknowledge the good quality work of the installation of my furnace and heat pump by your installers, Alvin and Brian on June 11, 2010. I was particularly impressed by Alvin. He was unhappy with the air duct installation as found. He corrected this in order to achieve a balanced and quiet air distribution. Both gentlemen, Alvin and Brian, need to be commended for their quality work. About our comfort advisor, Trevor, Lennox did a very good job of training you, and you became well qualified to represent Classic Aire Care and Lennox.
