I installed a Goodman 3 ton heat pump 5 years ago. changed over from a package unit to a split as we remodeled/added on and moved the unit to a different area. No problems at all and works great. Had about a 40 ft. electrical and copper run to make plus break out a new return duct and insulate all. Have a co-worker that is an HVAC guy and he got me the unit at cost . Installed it all myself and saved a couple of grand. Only thing I need to add to it to make it almost totally care free is an external temp switch to automatically swap from heat pump to strip at lower temps, it rarely gets real cold here though and we just swap it manually at the control....
