Leon Joseph was the technician who came to my house when I called for someone to come and see why my HVAC system was not coming on. He was at my house within about 20 minutes of my call. Who is extremely friendly, knowledgeable, and took care of the problem in a very timely manner. Manner. He recommended I get the service plan so my system would be maintained twice a year which I did indeed purchase. I paid nothing for this visit because my system was still under warranty.
