Patterson Heating and Air Conditioning diagnosed an AC problem for us. They did a good job but the price was a little too high for us right now so we are going find a different way to solve the problem. It's hard to say at this point exactly how, but I'm in construction so I have friends who do HVAC and we may just buy the unit ourselves and have a friend put it in. I think they're honest and their work is good. I'm sure their price is probably the same as any other out there, it's just that we aren't trying to go into debt right now.
