ARLINGTON, Va. — The Air Conditioning Contractors of America (ACCA) announced that its Contractor Comfort Index (CCI) for May climbed to 77, the second straight month in which the CCI has reached its highest level in the three years ACCA has been tracking HVAC contractors’ opinions on short-term economic growth. The April score was 71.

The CCI also shows that contractors are feeling more confident than they were 12 months ago when the CCI was 70.

The CCI is calculated based on a survey of the association’s HVAC 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. Weighted and averaged into one number, a CCI of 50 or above reflects anticipated growth.
