When I found out my furnace had cracks in the heat exchanger I phoned Airpro which installed an A/C unit in 2003. It has worked flawless. I do not know a lot about furnaces and when Rob of Airpro came out he took the time to explain the differences between the different levels of high efficient furnaces. Do to my past experience with Airpro I had them install the furnace.
The did a great job on the install, took the old furnace away ,left no mess and the workers were very courteous and the price was competitive .
