Contractors are a little more apprehensive about the economy as the year ends, according to the latest Contractor Comfort Index survey from the ACCA.

For November, the index number is 64 on a 100-point scale. That’s a four-point drop from a month earlier but still higher than the year-ago figure of 59.

Any number above 50 suggests most contractors feel positive about the economy. The next index will be released by the Air Conditioning Contractors of America near the end of December.
