I work at a company in MA that connects homeowners to energy efficiency resources, including Mitsubishi mini split ac/heat pumps and other brands as well. You can call our free energy efficiency hotline at 617-963-8141 (mon-fri) for help finding a local installer or you can put in a request for a free consultation anytime at
www.sagewell.com/takeaction (for heat/ac pump consultation select the box for energy efficient heating and cooling and then ductless mini split system on the form).
