ACCA members remain bullish on the HVAC market economy’s prospects, according to a new survey.

For March, the Air Conditioning Contractors of America’s Contractor Comfort Index is at 73 on a 100-point scale. That is one point higher than February and eight points above year-ago levels.

The index is based on a survey of members about their feelings on current and future business prospects, as well as staffing levels. Any number above 50 indicates most members feel positive about their companies.

The April index results will be released around the end of the month.
