The present invention involves an air conditioner including an air handling housing having a sidewall and defining first and second compartments. First and second tangential blowers are disposed in the first and second compartments, respectively. Each of the tangential blowers defines an axis with a coaxially disposed shaft end mounted in the sidewall. A motor drives the first and second tangential blowers. A belt and two pulleys rotatably connect the first and second tangential blowers. The belt engages the pulleys, and each pulley is mounted on a respective one of the shaft ends by a tolerance ring. A bearing assembly for rotatably supporting the shaft ends includes a support plate spaced from the sidewall. The bearing assembly further includes an outer race and an inner race. The outer race is connected to the support plate and the inner race is connected to the shaft end. The support plate is spaced from the side wall to inhibit heat transfer between the first and second compartments and the bearing assembly.
