Don't know the difference between a Fedders SV12A10 Slider Casement Air Conditioner 12,000 BTU 115V and a Frigidaire FAK083J7V Chassis Room/ Window Air Conditioner 8000 BTU 115V? Bet 'MIKE' of Mike's Air Conditioning does. "He lives and breathes this stuff," his secretary says. Visit his barely converted garage repair shop in Canarsie and while you wait you'll probably hear him on the phone talking jargon with customer after customer, like a call-in radio show. Walk through the graveyard of cooler casings and you can watch his black albino assistant reconditioning ancient units. Buy one and it might break after a month, like mine did. Perhaps Mike believes, as I do, that consumerism can't mask its inherent fraudulence, that technical knowledge is more worth caring about than technical expertise, and the best reason to shop is to interact with eccentrics. For example, his name isn't actually Mike.
