I am very satisfied with the service that I received from this company for the installation of a standard central AC unit for a triplex rental unit and for the installation of ductless AC units into a 3 story century home heated by radiators. The sales manager was very knowledgeable and experienced, responded to my questions thoroughly, customized the installation to meet my needs, and did not try to oversell me. The installation crew were polite and efficient and the sales manager followed up to make sure that everything was done well. A small accident happened during the installation and something broke and it was replaced promptly. The units are functioning very well. I highly recommend this company.
