I had a wonderful experience with Vanderford Air. David was a joy to work with and super helpful. They did a great job on the install. I am suppose to receive a thermostat with my new unit and that didn’t get installed, but David is working on this issue as I am writing this review. I need a wireless thermostat because my wired one is upstairs and the wireless they sent doesn’t work with my unit. I feel they will come through for me since I have spent some pretty pennies with them.
