This customer's opinion of Delta Mechanical Started out in the higher ratings. I used Delta as the Home Depot installer of my new $16,240.00 Heating and Air Conditioning unit on 5-5-16. The install went well until which time the necessary rebuild of the attic entrance in the garage was needed. This was told to me to have to happen in the next few days. As I right this review, it is now 5-23-16 and the completion of this is still not finished. I called Delta about this fact on the 4th day. They said they would get someone on it. It has yet to happen. Serious disappointment here!
