"We recently moved to NJ and bought an existing home that unfortunately needed considerable HVAC and some electrical work, fortunately however, we found Dave Marshall and his crew, Don and John, of DM Solutions to fix our problems. They responded quickly with exceptional expertise, resolving every issue to our complete satisfaction and at an extremely reasonable rate. Their work ethic appears to be totally driven by customer satisfaction which we find rare this days. If you have plumbing, electrical, or HVAC issues, these are the guys to call! Sincerely, Dave B."

"I actually had 2 systems installed. The main HVAC system for the 1st floor and a 3 zone ductless system upstairs. They were done in one day, very professional and cleaned up afterward. They were more than competitive in price and it was a pleasure doing business with them. J G., Phillipsburg NJ"

"The technician was very professional and was able to answer many of my questions about the condition of my HVAC system that I inherited and its probable lifetime. I sensed that he was being honest and straightforward. Rather than accept his extensive list of possible replacement parts, I opted to have him install the one that he believed to be the most urgent- the capacitor. So far the unit seems to be functioning well."
