I've worked with Gonzales Heating & Cooling quite a few times -- I was employed through a company that coordinated repairs for a housing program- I used Gonzales at least 30 times in 2 years. Gonzales Heating & Cooling ALWAYS treated our clients well and were consistently priced under the competition- we almost always got calls from clients complimenting the professionalism and courtesy of the tech that went out and thanking us for sending them. Because of this I chose to use them on my own home when I bought new AC unit in 2010- very happy with everything. 5 years later, I had to call them out for an issue - called on Sunday evening and they had a tech out at 8am on Monday (which is a big deal in the middle of August in Phx!) They are a great company to use- always super friendly and trustworthy. I definitely recommend!
