Our heating system went down Monday during subzero temperatures and AA Service Co. Heating, Cooling & Plumbing was called. A technician was able to check on our system within a few hours. Unfortunately we needed to replace the 20 year old unit. Fortunately AA Service Co. was back the next day first thing in the morning to install a new HVAC system. In spite of subzero temperatures, two technicians worked nonstop from 7-3:00pm to assure our new unit was up and running smoothly. We are extremely grateful for the top notch service we received—and a much warmer home !
