Our Palmdale area A/C technicians returned to a restaurant to repair their swamp cooler. The unit needed its bearings, shaft and blower pulley replaced. The technicians were able to remove the old bearings and pulley, but found the shaft was so badly rusted that it would not come loose. After several attempts using force and torches, unable to remove. Due to condition, we're recommending full replacement of the swamp cooler at this time.
