Where should you place the exhaust hose of your portable air conditioner?

1
Choose the best location for your air conditioner
Position your air conditioner close to a window or door. The shorter the exhaust hose, the more efficiently warm air is expelled. Long hoses lose heat, reducing the performance of your air conditioner.
2
Securely connect the hose to the unit
Attach the hose firmly to your air conditioner’s outlet. Ensure it fits snugly, leaving no gaps where warm air could escape. Double-check that all connectors are securely fastened.
3
Direct the hose outside
Feed the hose through a window, door, or a specially designed opening. Make sure the hose remains straight and avoid sharp bends or kinks. A free-flowing air path allows your air conditioner to work efficiently, providing maximum cooling.
4
Seal everything tightly
Any window or door used for venting must be well insulated to prevent warm outdoor air from entering and to keep the cool air in. Using acrylic is an excellent option, as it can be ordered to fit your specifications. This solution ensures a professional finish that’s both practical and durable.
Tip
We recommend using 4 mm thick acrylic window seals. With products from our range, you can easily order a pre-cut sheet with an exact opening for your exhaust hose. No DIY sawing required—just install and enjoy.

Invest in effective window sealing:
An airtight seal stops warm air from seeping in and prevents cooled air from escaping. Acrylic is perfect for this job. Its excellent insulating properties mean your air conditioner doesn’t have to work as hard. Our 4 mm acrylic air conditioner window seals are specifically designed to make this process easy, and they’re available pre-cut for immediate use.

Place your air conditioner strategically:
Position the unit in a cool, shaded area of the room. Close nearby windows and doors tightly to avoid extra heat coming in, ensuring the air conditioner doesn’t need to battle the heat unnecessarily.
3
Optimise the hose airflow:
Make sure the exhaust hose is straight and free from obstructions or kinks. A smooth airflow helps your air conditioner work more efficiently and maintain a cooler environment.
