Common Eastern Bumble Bee in picture. 

We used https://www.insectidentification.org/  to identify our bee. This is a great site! You can narrow down your search into the state you are located in and then what sort of insect you are looking for. We could see our bee was a Common Eastern Bumble Bee because it had a furry abdomen  and a yellow stripe under his wings. Carpenter bees do not have fuzzy abdomens! 

We picked up our lazy bee and brought him into a bug enclosure with some flowers and sugar water (bee Gatorade!). We just kept him for a little while for observational purposes and then we let him free to return to his colony. These bumble bees are hardy and can be active in cooler temperatures than many insects, he might have just needed to warm up some with the day to regain his energy!
