Our family has used 6 & Fix for over 8 years. This company has not only provided our maintenance but has also advised us in creating multiple zones. Eventually, they helped us select a new system. When that new system was struck by lightning, top management became involved and supported us through the whole claim process. They stand behind their work. We have never felt abandoned. Over time, they have helped us cut our electric bill in half. Every room in our home is consistently comfortable. Nothing is more important than knowing your system will work, and there is a guarantee to support their service.
