JN Brown of the Jim Brown Company found this wicked 7.5 ton installation in a church. It may have been the good intention of the budget committee to save some short term contributions in this installation, but judging by the size of the single 12″ supply and the 12″ return duct, the previous installer was sowing some seeds for Brother Brown to reap the rewards of. A perfect candidate for a duct renovation, wouldn’t you say?
