This heat pump was installed when my new house was built in May 2010. In January 2011 it required piston replacement when it stopped heating the home. Then in June 2012 it required a replacement of the indoor evaporator coil when it stopped producing A/C. Then in June 2014 it required replacement of the outdoor evaporator coil when it stopped producing A/C. So in the first 4 years, it has required 3 major repairs. Sure, Goodman provides a 5-year warranty on all parts. But my most recent repair still cost over $1, 000 for the labor and refrigerant. (The refrigerant is NOT included in the warranty, and that alone cost more than $600 this time.) I complained to Goodman, who told me I should have paid for the additional labor warranty as well. I suppose if you insist on buying a Goodman heat pump, then I would recommend the full labor warranty. But any person with half a brain should simply choose a heat pump from a company that is NOT widely recognized as the worst in the business (seriously, check any 3rd party review site). I will never be a Goodman customer again.
