It was the coldest night of the year. The heating system stopped working and the temperature dropped to a dangerously low level inside our home. Folkes responded to my call and Tony, their technician showed up on time as promised. His diagnostic approach was meticulous. His demeanor was reassuring. He found the faulty part in about 20 minutes. Replacement was available on his truck. He got the heating back and rechecked the system to make sure everything worked well.
