I had high hopes after reading the reviews here and after our first meeting with Accu-Air. Things got strange after that. Issues: (1) It took several days to get a quote. (2) The quote had the wrong size for one of our AC units. (3) When questioned on the equipment size, he claimed that he drove by our house to confirm the size of our current equipment, then insisted our current equipment was different, smaller model than what we actually had. This insistence upon something that was both wrong and easily checked was quite odd. (4) The quote included a furnace that we weren't sure we needed on one floor, and no option w/o a new furnace. (5) When questioned on the furnace, he painted a picture of our current equipment that was somewhat inconsistent with and much worse than what we saw and discussed on his visit.
Perhaps he had a bunch of people asking for quotes at the same time and got us confused with another customer. This would explain both the delay and confusion. Whatever the reason, it was frustrating to wait several days for the quote and then deal with these issues. We gave up on them.
Pros: Seemed friendly, serious, and conscientious at first
Cons: Slow in responding and seemed confused about details
