I had a ductless mini split air conditioner that i needed to have installed. Called a few places but they would not install unless they had supplied the hardware as well. Then i talked to Dan at D P Solution. He was professional, courteous, knowledgeable, prompt and efficient. The system was installed the next day and everything was perfect. They even wiped down the outside walls to ensure that everything was clean before they left the site. Definitely would recommend.
