Dispatched for heat pump not coming on. After a thorough diagnostic of the whole system it was found to be a fault during the transition of the operation. This includes from heat to cool, cool to heat, or heat pump to back up heat. This is cause due to the way the system was designed and installed. In order to remedy the system it would require an extensive rewire and new interface. Will follow up on Wednesday Dec 17 Thank you for allowing us in your house to provide the perfect home service and for being a member of the perfect family service club from your LBA Lead Service tech Calvin.
