Dalco recently installed a Mitsubishi Mini-Split system in my 78 year old house. With lath & plaster surfaces, block & brick walls along with non conventional framing components, it proved to be a challenging installation. Marc was quite thorough with his communication and very patient in answering my numerous questions. His talented technician, Ryan, persevered & kept a good attitude throughout the installation that took much longer than anticipated. I greatly appreciate their professionalism & expertise.
