''That's a big comeback win and one we needed in the room,'' DeBrincat said. ''Hopefully we can keep moving with this. Getting two goals was nice. I get a few puck bounces there and get lucky and it goes in. But it was good timing for me. We definitely needed this win.''
Chicago's Anton Forsberg had 35 saves to beat Carolina for the first time in three career meetings.
Darling, who spent the previous three seasons with the Blackhawks, stopped 26 shots for the Hurricanes.
''It was a tough segment for the power play,'' Carolina coach Bill Peters said. ''We didn't get a (power-play goal) and when you're not winning the special teams battle it makes things hard. We got some good looks when it was 3-2 but weren't able to finish.''
Carolina led 2-0 after an opening period in which the Hurricanes outshot the visitors 16-15.
''I had a couple of chances early,'' Saad said. ''You miss those chances and they end up scoring. You definitely want one, and it was great to get it in overtime. It feels good. But the biggest thing is contributing to a win.''
McGinn put the Hurricanes ahead at 6:53 on a backhander from the left doorstep with assists from Derek Ryan and Justin Williams. McGinn has goals in three straight games, while Ryan has points in three straight and Williams has assists in the last three.
Skinner added his eighth of the season, unassisted from the same spot at 9:01.
The Blackhawks scored on a rush just after a power play ended at 7:34 of the second, with DeBrincat converting on Jonathan Toews' pinpoint pass to the right doorstep.
Back came Carolina at 9:58, with McGinn roofing the puck past Forsberg on a rush.
DeBrincat scored his second goal early in the third, and Forsling tied it on a blast from the left point with 9:31 remaining.
''We dug a hole again, but I thought we hung in there,'' Blackhawks coach Joel Quenneville said. ''Certainly scoring that late (Forsling) goal helped. I liked their response coming in after (Carolina's) third goal.''
