The technician is the owner. He performed a very thorough cleaning and testing of the unit and since the unit had not been cleaned out in years took extra time to clean the motor component without any extra charge from his usual fee. He seems like a patient guy and you feel comfortable asking questions while he works. He came on time and cleaned up after the job. He does not seem to be someone who will only fix what is appropriate and I did not feel pressured to by any extras.
