Terrance was great. I gave him a warning that there was a lot to be done and he didn’t hesitate to help. My hvac wasn’t working at all and my last hvac guy bailed on me mid job! It’s been broken for at least two months now and the problems my last HVAC guy told me I had going on didn’t make any sense. Terrance was very professional, informative & knowledgeable. He kept me in the loop at every step. The job took alot of work but he got everything up and running. I’m very grateful. He gets a 10 out of 10! Book him!
