Member companies are a little more positive about the nation’s economy, according to a recent ACCA survey.

The Air Conditioning Contractors of America’s May Contractor Comfort Index registered a 68, which is three points higher than April’s number. Anything above 50 indicates growth is expected.

The index is based on a survey of members on how they feel about business prospects in the near term.

“The CCI tool was introduced in February, so we always keep in mind its 'newness' as it builds a picture over time," said Kevin Holland, ACCA vice president for business operations and membership. "However, as a snapshot of current attitudes, it is clear that ACCA members are putting the 'cautious' in 'cautiously optimistic.'

"It will be very interesting to see how the index moves throughout the peak cooling season,” Holland added.

The next index will be released in the last week of June.
