Latest Reviews and Complaints
Reliable furnace maintenance
My furnace broke down last winter, which was in fact extremely uncomfortable for me especially since winter is approaching. I contacted McNally’s Heating & Cooling and they were very quick to assist me. The technician arrived the next day and inspects and even performed a maintenance check. They answered my questions quite politely and explained everything to me, after they finished my furnace worked optimally. I was really feeling overwhelmed, knowing I could stay warm through those cold months. The quality of the service was outstanding and the cost was decent too which I appreciated so much.
