Members of the Air Conditioning Contractors of America are feeling optimistic about short-term growth this year.

The association released its June Contractor Comfort Index, which had a score of 66. An index number over 50 reflects anticipated growth for ACCA contractors.

The ACCA began measuring contractor attitudes toward short-term economic growth in February 2010. While the June CCI does reflect a positive outlook among contractors, the number is lower than the June 2010 CCI, which was at 69.

The CCI is calculated based on a survey of the association’s contractors, who are asked how positive they feel about new business prospects, existing business activity, and expected staffing decisions in the short-term future.
