As the weather warms in much of the country, the mood of ACCA members is improving as well.

The latest Contractor Comfort Index from the Air Conditioning Contractors of America is 65, up seven points from February. The figure represents the surveyed short-term outlook of member companies. A number over 50 represents positive feelings on the economy among those surveyed.

The number is down slightly from year-ago levels. In March 2012, the index stood at 69.

Index results for April will be released at the end of the month.
