I've had these guys out twice. 1st time to look over my a/c unit. Informed it is 23 years old but is working good, just needs refrigerant. Today I had the refrigerant added and expected to pay out the nose (it's $100lb) but only paid $280! Guess I'm just lucky but they really could have taken me for more if they were shady. Also the techs are informative and professional.
