A portable air conditioner only works effectively when the exhaust hose is correctly set up. Without a proper system to vent warm air outside, you won’t achieve the cool atmosphere you’re aiming for. In this guide, we’ll walk you through the best way to position your air conditioner’s exhaust hose step by step. We’ll also share some handy tips on using materials to seal your windows effectively, helping you maximise your air conditioner’s cooling efficiency. Read on to learn how to get the most out of your portable air conditioner.
What exactly does the exhaust hose of a portable air conditioner do?
Here’s the deal: the exhaust hose is responsible for venting warm air from your room to the outside. While it’s the hose’s only task, it’s an incredibly important one.
Portable air conditioners pull air from your room, cool it, and then push the cool air back inside. However, the warmth extracted during this process needs to go somewhere. Without the exhaust hose, that hot air lingers in your room, preventing you from reaching the desired temperature. Channelling warm air outside keeps your space comfortably cool.
That’s why it’s crucial to ensure the exhaust hose is functional and unobstructed. If the airflow is restricted, your air conditioner won’t work to its full potential—leaving your room warm and your energy bill unnecessarily high.
How do you install the exhaust hose of your portable air conditioner?
With a little preparation, installing your air conditioner can be a quick and straightforward process. Follow this step-by-step guide to avoid common issues like air leaks and unnecessary energy loss.
steps
-
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.
-
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.
-
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.
-
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.

Common mistakes and how to avoid them
Getting your setup right from the start is half the battle. We’ve spotted some common mistakes people make while installing the exhaust hose, but you can avoid them with a bit of preparation.
Placing the air conditioner too far from the window: A longer hose length compromises efficiency. Always position your air conditioner as close to the window or door as possible.
Poorly sealed hose connections: Make sure every connection is airtight. Even small gaps or loose fittings can result in heat leakage, reducing cooling efficiency and driving up your energy costs.
Too many bends in the hose: A straight hose ensures smooth airflow. Avoid twists and obstructions to help your air conditioner run at its best.
Inadequate window sealing: Without proper sealing, warm external air re-enters the room, while cooled air escapes outside. Using acrylic to create an effective seal solves the problem. Acrylic is lightweight, sturdy, and easy to custom-fit for any window.

What materials can you use for sealing windows?
A well-sealed window is essential for keeping warm air out and cool air in. This not only helps your portable air conditioner work more efficiently but also keeps energy costs down. Various materials can be used to create window seals, though some are more effective than others. Here, we’ll go over the options, highlighting why acrylic is our top pick for a sustainable and energy-efficient solution.
Acrylic: A smart and durable choice
Acrylic is an ideal material for sealing windows when using a portable air conditioner. It has several significant advantages:
Outstanding insulation: Acrylic’s insulating properties ensure warm air stays outside while cool air remains inside, thereby increasing the efficiency of your air conditioner.
-
UV-resistant: Acrylic is long-lasting and maintains its sleek appearance, even when exposed to sunlight for extended periods.
-
Polished finish: The clear, professional look of acrylic creates a tidy and effective solution for your aircon setup.
-
Easy to customise: Lightweight and easy to cut to the perfect size, acrylic can effortlessly fit any window opening.
-
Eco-friendly: Acrylic is recyclable, making it a more environmentally friendly choice compared to other materials.
Alternatives: fabric seals and duct tape
There are other options available, such as fabric window seals and duct tape. However, these are often less effective and durable compared to acrylic.
Fabric window seals
While these flexible seals are easy to install, they offer poor insulation. Cool air easily escapes, and warm air can still enter. Additionally, they don’t look as tidy as acrylic seals.
Duct tape and similar adhesives
These may serve as a temporary fix but provide limited insulation and can leave sticky residue on windows and frames. Such materials are not designed for efficient or lasting sealing.
Why acrylic is the best choice
Compared to alternatives, acrylic offers the perfect combination of insulation, durability, and a neat finish. Choosing acrylic as your window seal minimises energy loss and ensures your portable air conditioner operates at its peak performance. Properly sealed windows guarantee a consistently cool room while helping you avoid unexpected spikes in your energy bills.
At PlasticSheetsShop, you can order high-quality air conditioner window seals, fully customised to your requirements, including a precise cut-out for your exhaust hose. This allows for a hassle-free installation, perfectly tailored to your needs and immediately ready to use.
How can you make your portable air conditioner more energy-efficient?
Want to save energy while keeping your home cool? It’s possible! With just a few practical adjustments, you can get the most out of your portable air conditioner while reducing electricity usage.
Tips for maximum efficiency
- 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.
- 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.
