How do I cool down a windowless living room without window access?

I dealt with this exact setup in a railroad apartment years ago, and standard floor fans are basically useless because they just oscillate air in a wide, weak pattern that dies out after five feet. To acutally move cold air from a bedroom into a windowless common area, you need **air circulators**, specifically something like a Vornado. Unlike a regular fan, these push a tight column of air that can actually travel the length of a hallway. You want to place the fan inside the bedroom doorway, on the floor, aimed slightly upward into the living area to create a jet of cold air. Don't even bother with a swamp cooler in NYC. Those only work in dry climates like Arizona. In New York, the humidity is already trough the roof in July, and adding more moisture to the air will just turn your living room into a literal steam room. It makes the heat feel twice as heavy and won't actually drop the temperature. If you relly need an AC in that middle room, your only real option is a **portable unit**, but you'll have to buy a vent extension kit to reach the nearest window. Just be aware that the longer the hose, the less efficient the cooling becomes because the hose itself radiates heat back into the room.

Another trick is to look for an exhaust point you might have missed. If your bathroom has a ceiling vent that actually draws air out, you can sometimes vent a portable AC into that using an adapter, though it's a bit of a DIY hack. But if you can't vent it, you have to focus on the push-pull method with fans. Put one high-powered fan at the floor level of the bedroom blowing cold air out, and if possible, place another fan in the living room blowing back toward the bedroom to create a circular flow. It's the only way to keep the air from stagnating when you're using the stove or doing dishes.

I'm curious about the Vornado thing—does the size of the fan realy make a big difference for a long hallway? I saw a smaller one at the store but I’m worried it won't have enough kick to reach the kitchen. Also, what about those DIY tricks where people put a bucket of ice or a frozen gallon jug in front of the fan? Is that just a waste of time in NYC humidity or woud it actually help keep things cool while the stove is on?

The ice bucket thing is a total myth for NYC. It just turns your living room into a swampy mess once the condensation starts and the ice melts. Don't waste your time. If you decide to run a long vent for a portable AC, you absolutely need to insulate the hose. That plastic tube gets roasting hot and basicly acts like a radiator, cancelling out half the cooling. Grab some reflective bubble wrap and tape it around the pipe. Also, look specifically for a dual-hose unit. Single-hose models create negative pressure, wich sucks hot air from the hallway or under your front door into the apartment to replace the air being pumped out.

If you're using the stove often, check if your range hood actualy vents outside. Most NYC rentals just recirculate the hot air, wich is a nightmare in a windowless room. If it's just blowing air back at you, you're basicly running a heater while you cook. I’d also suggest a beefy dehumidifier for the common area. It won’t lower the degrees, but it makes the 'heavy' air feel much crisper. It does kick out a little heat, but dry air at 80 degrees is way better than 78 degrees with high humidity in a windowless box.
