If you have a portable air conditioner without a window, but you do have outlets on the wall, there are still some suitable places to position the unit for efficient cooling. Here are some good options:
Through a Sliding Door or French Door: If you have a sliding door or French door that opens to the outside, you can install a venting kit designed for portable air conditioners. This kit allows you to vent the hot air from the air conditioner through a small opening in the door while keeping the door mostly closed. Make sure to seal any gaps around the venting kit to minimize air leakage.
Venting into a Drop Ceiling: If you have a drop ceiling or a suspended ceiling in the room, you can use a venting kit to exhaust the hot air from the portable air conditioner into the ceiling void. Ensure that the ceiling tiles are properly sealed around the vent to prevent the cooled air from escaping into the ceiling space.
Venting into an Attic Space: In certain cases, if you have access to an attic space above the room where the air conditioner is located, you can vent the hot air into the attic. However, be cautious of potential heat buildup in the attic, especially during hot weather.
Venting into a Laundry Room or Bathroom: If you have a nearby laundry room or bathroom with an exhaust fan or ventilation system, you may be able to vent the hot air from the air conditioner into that space. This can help dissipate the heat while providing some extra cooling to the adjacent room.
Venting through a Dryer Vent: If the portable air conditioner is in proximity to a clothes dryer, you might consider venting the hot air through the dryer vent. However, ensure that the vent can handle the additional heat load and that the air conditioner's exhaust doesn't interfere with the dryer's performance.
DIY Air Duct Setup: In some cases, you can create a DIY air duct using insulated ductwork to channel the hot air from the portable air conditioner to an unoccupied space like a storage room or unused closet. Ensure proper sealing to prevent any heat leakage back into the room.
When setting up any alternative venting arrangement, it's essential to maintain proper ventilation and ensure that the hot air is adequately directed outside the living space. Additionally, always follow the manufacturer's guidelines and safety instructions for venting and operating the portable air conditioner. If possible, consult with a professional HVAC technician to ensure the setup is safe and efficient.
