This was our first time using Cool Tech Mechanical, and everything turned out fine. We had them do a full air conditioning installation minus any duct work. It was easy to schedule with them, and they showed up on time. The installation was way faster than any of the other companies who quoted this job for us, and it was also much cheaper. The only real qualm I had was that the job on the inside was a little sloppy, and I had to call them out to re-do it. The were receptive to coming back out, and everything ended up turning out fine.
