Max Mechanical Air Conditioning & Heating Inc is a company that I have used in the past. When I was having an issue with my unit, I reached out to them. They sent one of their techs to work on the unit and thought he had it fixed. Turns out it wasn't, so they sent another guy out to work on it. He thought it was the same problem as before. But it wasn't. They finally sent a third worker out, who brought over the other two techs, and together they took care of the problem. They did a wonderful job and did not charge me extra when they came back multiple times to diagnose and resolve the issue I was having.
