"This was great service. I had 2 different technicians from another company recommend changing just the condenser using the older (R22) refrigerant. The consultant from True Mechanical helped me choose a high efficiency replacement air conditioning system which lowered our electric bill and has a warranty of 10 years. We are concerned about the environment, so we are glad the system uses the new greener R410A refrigerant. The installation went very well. The technicians laid down tarps and wore shoe covers. They left our home extremely neat. We could not have asked for anything more. We have already recommended friends, and will continue to do so."
