The serviceman, Greg Chalmers, arrived within the given time frame to fix our fairly new dryer which had stopped heating during drying cycle. Our dryer is a full size stacker and he didn't have to remove the closet door where the washer/dryer was and he just climbed up the ladder to reach behind the dryer to fix whatever was wrong with it. Quick, efficient service. left a business card when he left and asked us to call if the problem persists.
