"We were in town for a few days trying to get some things taken care of with our Colorado home prior to our move from North Carolina. We received excellent customer care from Les at DMC Services. He was punctual for the appointments. He clearly explained the work needed and the cost. The work performed was quality and the cost was fair for the time spent and products installed. We could not have been more pleased with the attention to detail and customer care. We will use DMC Services for our future HVAC needs and highly recommend the company."

"Henry is professional, knowledgeable & friendly. He knows what he is doing. Plus…shows up on time!!!"

"Outstanding service.  Technician arrived on time and performed diagnosis.  Although unit appeared to be working, it was not detected until later that the thermostat would not turn off the unit, so the new thermostat was not installed.  Technician and office personnel very helpful in coordinating return visit to install the new thermostat at no additional charge.
Normally, I do not write reviews.  These guys earned an A rating and my business for life.
