"OAC 4000: Weather Is Now Optional There was a time when the weather decided everything. It told you where to sit, when to stay inside, and how long the evening could last. Then came the OAC 4000—a rugged, all-weather companion that rewrites the rules of personal climate. Equal parts air conditioner, heater, and fan, this is the unit you wheel into the garden when the summer won’t quit… or the one you leave humming outside your cabin, while cool air wraps around your living room like a fresh breeze off the coast. With 10,000 BTU cooling power, 6200 BTU heating, and the ability to operate in temperatures from 23°F to 131°F, the OAC 4000 doesn’t ask where it’s needed—it simply adapts. Rain, sun, chill, or sweat—it doesn’t matter. Just set the timer, press the remote, and let comfort roll in on twin ducts and turquoise steel."
