Contractors are continuing their cautiously optimistic outlook for 2013, according to the Air Conditioning Contractors of America.

The ACCA said that its Contractor Comfort Index for February was at 58. A CCI of 50 or above reflects anticipated growth.

The association began measuring contractor attitudes toward short-term economic growth in February 2010. The current CCI shows that contractors are feeling about the same as they were 12 months earlier when the CCI was 57.

The Contractor Comfort Index is calculated based on a survey of the association’s contractor members, who are asked how positive they feel about new business prospects, existing business activity, and expected staffing decisions in the short-term future. It is then weighted and averaged into one number.
