That sticky, unbearable humidity. We’ve already had a brush with it, which means now is the moment to make your cooling plans. First, invest in a blue-chip apartment air conditioner that does more than blow cold. Friedrich consistently places among the highest in the business. This 7,800-Btu big-room model (CP08N10, $259 at Gringer & Sons, 29 First Ave., nr. 2nd St.; 212-475-0600) has an easy-to-use, twelve-hour programmable clock (when you’re getting off the subway, it’s cooling your living room) and a remote, so you can make precise temperature adjustments without getting out of bed. Friedrichs cost more initially, but you’ll likely save in the long run: Replacement parts are readily available, and energy-saving features, along with a low electric bill, will keep you feeling green for years to come.
