goodmans quality control has improved alot over the years they used to have problems with coil leaks but that has pretty much been resolved they come with a good warranty and a copeland compressor. they are good budget units but the key is a propper install using nitrogen while brazing and installing liquid line dryers i usually put a suction line dryer on also no matter if its a heat pump or not just for added insurance. also pulling a vacuum atleast twice for atleast 45minutes each time and breaking it in between with nitrogen not air to remove moisture. also replace the copper lines especially if the old unit had a compressor burn out or you are switching from r22 over to 410a. and as for the comments about replacing contactors and capacitors it is good practice to replace capacitors and contactors every year with the annual service if you get an annual service contract those are the 2 most likely parts to fail on most any unit and only cost a few dollars to replace or at least keep some on hand that can be replaced on the spot. having to wait over the weekend for a supply house to open or pay a service tech $150 for a $7 part is not fun for a homeowner.I installed a 4 ton goodman in my own home 3 years ago.
