While the money an HVAC contractor can save when it comes to refurbishing flood damaged equipment versus replacing it may be appealing, the risks associated with it are far too great. 

In this month’s troubleshooting problem, the equipment that needs servicing is a split system heat pump, manufactured under the brand name Grandaire (ICP, Lewisburg, Tennessee). The indoor unit model number is WAPT304A2, and the outdoor unit model number is WCH5304KGA100. This is a 2.5-ton unit in a residential installation.

I created this service call to help technicians understand flooded unit repair. Dedicated to technicians after Hurricane Harvey and Hurricane Irma — I hope it helps. Good luck.
