“We received several quotes and D&D’s proposal was the most complete and cost competitive. They provided several options for me to choose from and weren’t trying to up sell me the most expensive unit available. The installation team arrived early which was great. They got right to work and installed an amazingly quiet HVAC. If I had any questions for them they were promptly answered. The work was completed by early afternoon and the system was (and still is) working. Everyone I worked with was very personable and professional. I would be very comfortable working with them again.”
