Buyer beware drhvacmechanical@***.com Dr HVAC Mechanical brandon mccollom www.drhvacheatingandcooling.com/ 817-507-**** See the BBB rating of an F, he does not give his address. He works out of his truck and has questionable practices. http://www.bbb.org/fort-worth/business-reviews/air-conditioning-contractors-and-systems/dr-hvac-mechanical-in-benbrook-tx-19193****/ We agreed to hire his to change out an outside unit, and remove the inside unit and clean it. We agreed on a price and he know we were in a bind but he was going to take care of it in three days. Late the night before he did the work, he sent an email in the night saying that the price was $200 more. He then went to change out the unit and then refused to remove and clean the inside unit but he wanted the same money. I refused to pay him until the cleaned the inside unit. Almost a week later he said he did that. He then refused to give me and invoice, the warranty papers for the unit he installed and the warranty he stated that he gives on labor. He threatened me many times over but never provided the paperwork he then shows up late at night and removed the unit. So instead of providing the paperwork and getting paid he choose to remove the unit...you decide
