I've used a 1300 PSI pressure washer to clean fins. As long as it's

Last Thursday our of our maintenance guys at work spent a few hours
straightening fins on a cooling tower for an air compressor at work. Last
summer someone hooked up a sprinkler under it to help it cool on very hot
days and the sprinkler was enough to bend fins. Of course, the bent fins
restricted air flow causing even more heating so they increased the
sprinkler pressure. . . . . . .

I plan to call the landlord in the morning (today is a holiday in the
US) and have them fix it. But I definitely am considering buying a unit
