They were too much of a hurry to get out of there before the weather hit, so they were trying to rush things. I wanted to get preventive maintenance done on my air conditioning unit and they could not hook up the connections to measure the pressure of the coolant. Which surprised me because every time I’ve gotten preventive maintenance from other places they could hook it up with no problem. But eventually he went back and sorted it and connected it when I ask him to do so! I was surprised to see that this was rated number one on Dirty Scam, which disappointed me, I won’t use them again.
