The New Goodman 14 SEER condensers, do NOT come with a piston. Think about it if you are putting in 1/2 system, changing from R22 to R410A or may need a piston match.

They may do that because the matching Goodman air handler or matching Goodman coil has the piston already.

Have well under 100 compressors fail in warranty because there's liquid flood back in certain conditions and the savings evaporate.

It's crazy to not include a piston - the coils are in nominal tonnage only for 13 seer; a lot of contractors won't buy the piston if a bigger coil is needed to get the efficiency.

It adds what, probably under $1 per unit - just increase the price by a buck for god's sake.

You don't automatically get a flare nut when you buy a flare fitting either. You have to buy it separately.
