I called Air Professional Associates, LLC because there was a problem with the heating system. They came in all pepped up and ready to go and went downstairs to look at the system. After about an hour, I went down to check on them and found them just sitting around chatting about what could be wrong. I asked them for an update and they said they were pondering the problem, but really they didn't have a clue. I called another company and even went online myself to see if I could figure out the problem. It turned out to be a common problem with this particular system and by the time the Air Professional guys were ready to go, the other company had arrived to fix the problem. I told the technicians from Air Professional to give me a bill for their time and I paid it, but my conclusion is that they just weren't experienced at all. I would not use them again, nor would I recommend Air Professional Associates, LLC. The other company was able to fix the heating system without any pondering.
