I have been in the construction business for over 25 years and when I needed to have a heating and cooling unit installed in my parents home (they are 86 so I didn't need anything that would cause problems) I went with the recommendation of a good friend to use Scottsdale Air. It has been over a year since the job was done and everything about the job was done perfectly. We had commercial grade slot type vents installed (suggested by Mike, the owner of Scottsdale Air) and wow are they wonderful for moving air, and doing it quietly. The install was meticulously carried out by 2 excellent techs. We recently had a condensate pump act up.....a manufacturers problem, and Scottsdale Air came right out and replaced it with a quieter one. Again, the tech was professional, informative, clean, and considerate. I continue to be very impressed. Thanks Scottsdale Air. Sincerely, Jon Gillan
