The Blades put the imminent departure of influential midfielder Michael Brown, who was suspended for the game, to the back of their minds as they ground out a hard-fought triumph.
Former United player Patrick Suffo should have put the hosts ahead on ten minutes, but the Cameroonian striker blazed over when well-placed.
Suffo spurned another chance on the half mark when he saw his angled volley drift wide.
Neil Warnock's men offered little as an attacking force in the first period, but claimed the decisive goal just eight minutes after the interval.
Bosnian defender Mo Konjic fouled Jack Lester in the box, earning a booking in the process, and the hit-man picked himself up to convert the spot-kick with little difficulty.
The Sky Blues responded well to the goal, but their best chance to level went begging when Callum Davidson put a free header wide.
United almost added a second in injury-time when Peter Ndolvu struck the woodwork, but Lester's strike proved to be enough.
The win moves United back into third, just a point shy of second-placed West Brom, while Coventry fall to 13th.
