That hose radiates heat back into the space, and on a warm evening the machine spends part of its capacity undoing its own work.\u003c\/p\u003e\n\u003cp style=\"font-size:16px;line-height:1.85;color:#333;margin:0 0 18px;\"\u003eThe Cold Sleeve wraps that hose in an Oxford cloth composite built to isolate heat and resist the abrasion of a hose dragged in and out of a window each season. It fits exhaust hoses of roughly 5.8 to 6 inches in diameter, which covers the common single-hose portable units, and it closes with two straps rather than a zip, so installation needs no tools and no hose removal.\u003c\/p\u003e\n\u003cp style=\"font-size:16px;line-height:1.85;color:#333;margin:0 0 18px;\"\u003eAt 150 by 52 centimetres and about 250 grams, it covers the full run of a standard exhaust hose without adding meaningful weight to the assembly. The fabric layer also protects the hose itself, which on most units is a thin foil duct that dents and tears after two summers of being pushed against a window frame.\u003c\/p\u003e\n\u003cp style=\"font-size:16px;line-height:1.85;color:#333;margin:0 0 18px;\"\u003eThe result is measurable rather than decorative. Less heat radiating into the room means the compressor cycles less, which means lower consumption and a room that actually reaches the temperature on the dial. It also makes a terrace, a garage or a basement installation look considered instead of temporary.\u003c\/p\u003e\n\u003cp style=\"font-size:16px;line-height:1.85;color:#555;margin:0 0 6px;\"\u003e\u003cem\u003eCooling a room while heating it through a hose is a solved problem.

style=\"font-size:15px;line-height:1.85;color:#333;margin:0;\"\u003eThe obvious user is anyone running a single-hose portable air conditioner in a bedroom or living room, where the hose crosses the room and the machine never quite keeps up. It also suits a garage or workshop installation, where the hose is long, the ceiling is low and the heat gain is worst. Renters who cannot fit a split system get the most from it, because they are usually working with the least efficient configuration and the hose is exposed across a whole room. Seasonal storage is easier as well: the sleeve stays on the hose, so the whole assembly goes back in the box covered rather than bare.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"product-promise\" style=\"margin-top:28px;padding:20px 22px;background:#f7f8fa;border-left:3px solid #1A3A5C;border-radius:4px;\"\u003e\n\u003ch3 style=\"font-size:17px;color:#1A3A5C;margin:0 0 10px;\"\u003eThe EastSupplier Promise\u003c\/h3\u003e\n\u003cp style=\"font-size:14.5px;line-height:1.8;color:#444;margin:0;\"\u003eSourced directly from vetted manufacturing partners, inspected before dispatch, and priced without distributor layers.
