The Goodman DSXC18 air conditioner is considered the best air conditioning unit in production as of 2015 according to air conditioning and heating website FurnaceCompare. This unit retails for between $2,059 and $3,089 as of March 2015, as compared to $2,659 and $3,769 for the Heil QuietComfort DXT+.
