We got a new system for only the cost of the equipment.
With only months remaining on our 10 year warranty, the heat pump failed. One Hour made a valiant effort to repair it, including 4 or 5 trips and replacement of most of the components. All at no cost to us. However, the cause of the problem remained unknown, so One Hour offered to install a brand new system (inside and outside) if we paid only for the equipment not the labor. We agreed and the job was soon completed.
