Defending champions Bob and Mike Bryan needed just 55 minutes to beat Paes, who reached last year's final here with South African Raven Klaasen, and Chardy 6-2, 6-3 at the Delray Beach Tennis Center on Saturday.
The top seeds will take on the Austrian-French pair of Oliver Marach and Fabrice Martin in the final.
The Americans dominated the match, starting with converting both their breakpoint chances to get ahead in the first set.
The unseeded pair of Paes and Chardy also did not help matters as they served three double faults. Their first service was correct only 52 percent, compared to 80 of the Bryan brothers.
Paes and Chardy tried harder in the second set but did not find the winning touch on the five break point chances they earned, wasting all.
On the other hand, the top seeds converted one of the two opportunities they got which was enough to seal the set and match.
Paes and Chardy's first service deteriorated to 45 percent in the second set, in which the pair double-faulted four times.Published 21 Feb 2016, 18:23 IST
