Massachusetts Public data on Ductless HVAC install costs (MASS CEC)
This may spark some interest, one of the rebate entities has published a data base on 11,758 Mini-Split install since the program inception (5 years or so). Mass guys- see where you stack up with the guys that you think are more costly and less costly than you. I took some screen shots- pretty cool info. https://www.masscec.com/cost-residential-air-source-heat-pumps
