I had a Heat pump installed by Joe S., Damon H, Ray M from Blue Dot and these technicains were very professional. They took the time to explain every piece of equipment installed. They cleaned their mess from the install and the extra mess from my family in the hall. I'm very please by the quality of work and yes i would recommend these gentlemen to install in my family houses if they lived in Maryland. Yes, I would use Blue Dot again because of these technicians.
