Stay away from these people. They are there to take advantage of customers. They showed up at my house. Indicated coils needed cleaning and the charge was going to be $200.Now they say that the service is $470, and as they did not want to start the job without a credit card on file they have already charged me without approval. As the system did not improve, they returned just to indicate that the equipment is small for the size of the house. How come they did not diagnose this from the start? STAY AWAY FROM THESE CROOKS!
