I called them to get their free estimate on a new ac unit. I was informed that there would be a 65.00 dollar trip charge for them to come out to get my free estimate. I asked why are you charging me when it is supposed to be free. They said if I went with them on the ac unit they would wave the charge. That's not free it's false advertising. I will never call them again.
