They installed the furnace in my home about two years ago and 6 repairs later it still doesn't work as well as I would like. Every service call they send out someone new and they make the same repairs that only temporally fix the problem and we are stuck with a broken furnace that was installed wrong in the first place. The billing department doesn't know what they are doing and they cancel appointments without calling. If it wasn't for the fact that I still hold a warranty with them I would never deal with them again.
