Blue Ribbon Services did a great job servicing my air conditioning and heating units. I had no problems with the work that they did and am satisfied with how everything turned out. The service was efficient and the work was done in a timely manner. The technician was precise and clear when explaining everything. I appreciated that he was on time, professional, and pleasant to work with. Blue Ribbon is priced competitively and I would use them again in the future if I need to.
