John and Atlas heating are a rare throw back to a time when service vendors were honest and cared about their customers. We got home from a vacation to find our heater out at 6 pm on a Saturday night. With temps dropping below 30 degrees we needed good help fast. John kindly spent over 2 hours on the phone troubleshooting and fixing our furnace never once getting frustrated at how green I am with furnace tech. John has a customer for life! I would refer this company out to all my friends and family!
