I am happy that I have been using Air Squad for the time that I have. I used them to replace a couple of units in the office, and they have also done some maintenance work. I think that the staff is very attentive and I have used them for different projects - so they always deliver great work. There are never any surprises when it comes to the pricing - it may not be the cheapest, but they let you know what it is, so they keep it honest. Overall, they do great work and provide great quality for what you're asking for, so I have no complaints.
