Performed summer tuneup on Trane. Heat pump, split system, system, running within manufacture specifications. Unit is brand new did not find any issues with system or concerns. However, homeowner and I did talk about potentially adding a N rush device to unit to lower the starting amps and help maintain a healthy compressor for years to come. I also gave some history that Trane used to install these from the factory and no longer do unit running at departure with an 80° temperature differential.
