Mr. John Abel has serviced our HVAC equipment before, and consistently has followed through with repair and bi-annual maintenance in a manner that represents the excellence of the John Waters tradition of excellent service to the customer. I would recommend John Waters Heating, Cooling & Electric to anyone. Their professionalism goes above and beyond. They did an excellent job and I would use them again without hesitation. I don't think anyone who chose to use them would ever be disappointed.
