I would put negative 5 stars if YELP system is allowed to do that. How we got to know this company as our AC is from Sonoran Air and we called Sonoran Air and Sonoran Air then sent Goettl to fix the AC. They charged us for $2k and forced us to sign the 3 yrs good club. The next following week, the AC is broken down again. They asked us for another $500. We would stop using this company immediately. Besides, the technician is rude.
