Keeping London Comfortable — Whatever the Weather.
Why Portable Air Conditioners Disappoint
Portable air conditioners are brilliant when set up correctly — but most people experience frustration because of a few common mistakes. Here's what goes wrong, explained simply.
Wrong Size for Room
A portable AC that is too small will never cool the space. One that is too large wastes energy and cycles inefficiently. Matching BTU to room volume is the foundation of real cooling.
Incorrect Positioning
Placement matters. A unit pushed into a corner or blocked by furniture cannot circulate air effectively, leaving hot spots and cold spots throughout the room.
Poor Airflow
Without proper air circulation, cold air pools in one area while the rest of the room stays warm. Correct positioning and fan support make the difference.
Exhaust Hose Through an Open Window
The most common mistake. The hose hangs out an open window, but the window gap lets hot outside air straight back in — cancelling out the cooling entirely.
Hot Air Returning Indoors
Without a sealed vent, warm exhaust air flows back into the room. Your AC works overtime and the temperature barely drops. A proper vent panel solves this completely.
Incorrect Ducting
Kinked, too long, or poorly connected exhaust hoses restrict airflow and cause the unit to overheat. Correct ducting is short, straight, and secure.
No Security
An open window with a hose hanging out is a security risk. Our vent panels seal the gap and keep your home secure — no need to leave windows ajar.
Wrong Expectations
Portable ACs are powerful but they are not magic. Understanding what they can realistically achieve in your space prevents disappointment and wasted money.

Window Vent Solutions
The exhaust hose on a portable air conditioner must vent outdoors. Here is why most people get this wrong — and how we solve it properly.
Why an Open Window Doesn't Work
The AC removes heat from your room and pushes it out through the exhaust hose. But if the hose simply hangs out an open window, the gap around it lets hot outside air pour straight back in. Your unit works endlessly, the room never cools, and your electricity bill soars. This is the number one reason portable ACs "don't work."
Our Custom Vent Panel Solution
We cut a panel to the exact size of your window opening, with a precision-cut hole for the exhaust hose. The panel slides into the window frame, sealing the gap completely. Hot air goes out. Cool air stays in. Your AC operates at full efficiency, and your home stays secure.
Vent Panel Materials We Offer
Plywood Vent Panels
Durable, cost-effective, and easy to customise. Ideal for a solid, long-term installation with a clean painted finish.
Acrylic Vent Panels
Transparent or tinted panels that let light through while sealing the window gap. A premium look for visible installations.
Polycarbonate Vent Panels
Virtually unbreakable, lightweight, and weather-resistant. The toughest option for long-term durability and security.
Removable Tenant-Friendly Solutions
Slot-in panels that require no screws or permanent fixings. Perfect for rentals — lifts out clean when you move.
We Fit Every Window Type
What Our Vent Installation Includes
Proper Exhaust Venting
Hot air is directed outside efficiently, so your AC actually cools the room instead of fighting a losing battle.
No Open Window Gap
The vent panel seals the opening completely. No warm air flowing back in, no insects, no draughts.
Security Improvements
Unlike a hose hanging out an open window, our panels keep your home secure. The window stays closed and locked around the vent.
Weather Sealing
Rain and wind stay outside. We seal every edge with weatherproof foam or silicone depending on the installation type.
Professional Finish
Cut to size, sanded, and painted to match your window frame. It looks intentional, not makeshift.
Tenant-Safe & Removable
For rented properties, our removable panels leave zero damage. Your landlord will never know it was there.
