In October 2011, I had my 23 year old furnace replaced by Delta with a high efficiency Lexnnox furnace. I was going to write this review sooner, but I procrastinated. It wasn't until recently, when I had a contractor in to install tile, that I realized just how good Delta's service was.
One of the things I valued most about the work Delta did, was that the installation team ensured I was ok with all decisions throughout the process. This included the new placement of the hot water heater, and where the external intake and outtake pipes for the new furnace would be installed. It would have been easy to just go ahead with what they thought best, but the fact that they sought out my approval first, was extremely appreciated.
Another important point in contrast to the recent contractor, was that the Delta installation team respected the conditions of my home. They laid out drop sheets from the front door to the basement, and took the proper care to not damage the walls while carrying in the new furnace.
I should also mention the thoroughness of the quote process. Unlike the other companies I got quotes from, Scott Padfield was extremely detailed. He examined the entire house, where others only focused on the furnace room. He made recommendations about relocating my cold air returns for better air conditioning performance, even though I wasn't getting an air conditioner installed yet.
In retrospect, I'm very satisfied I went with Delta Air Systems. I'm able to sleep easy and warm this winter knowing they've done a quality installation. Now I just wish they had tile installation guys with the same integrity. :)
Thanks Delta
