ACCA members continue to feel good about the economy - albeit a little less than they did a year ago.

Those are the results of the Air Conditioning Contractors of America’s May Contractor Comfort Index. For the month, the index registered 66. In May 2010, it stood at 68.

Any number above 50 indicates contractors surveyed by the association still feel positive about short-term business prospects. Higher numbers indicate better sentiments.

The next index will be released at the end of June.
