Product Information

Additionally, if your AC also expels humidity, this could promote the growth of mould and mildew in your attic which would risk structural and health complications. Unless the air can move from the inside out, you will not feel the benefit of your portable AC unit. Rooms with drop ceilings have the option of venting through these, as there is a large amount of space between the drop ceiling and the real ceiling, this can be filled with the hot air your unit is expelling from the room. The main obstacle to overcome when venting through a wall is creating a hole to connect your hose to the outside air so hot air can be expelled from the building.

You must use a roof window caulking kit (Velux) which is neither aesthetic nor practical to install.

Those of you who have the ‘proper’ non portable air conditioning units, do you have the air to air (correct term? It comes with a single external wall cap with 'fish tail' clip but its just for the inside of the room, so I'd need another, or something that'd the hose could fit into. Swinging doors or casement windows provide a harder challenge to vent through as they open at an angle, making sealing them difficult.

South facing windows won’t help, but a problem with portable air conditioners is that the hot air blown outside through the hose has to be replaced by something, and that something is usually more warm air drawn in from outside, entering through tricks vents or down chimneys etc. Then transfer these measurements onto the plexiglass, measuring a second time to ensure that they are correct, and cut the panel out. Understanding how your portable air conditioning unit works and how to set it up can vastly improve its effectiveness, saving you money on energy and regulating the temperature of your building.If you’re sick of sweltering uncomfortably during hot sunny days, an air cooler could help you beat the heat this summer. it isn’t perfect (we have a very awkward velux so had to use a kit that wasn’t made for our window) but does a good enough job if there’s one that would fit your window. We cannot accept liability for any damage caused or injuries sustained as a result of incorrect fitting of replacement spare parts or mis-diagnosis of a fault.

Completely covering your vents can cause your systems to work efficiently and potentially damage them. The Velcro stays on the window all year round and we just get the sheet thing out when we need the air con on. Should your product(s) arrive damaged by the carrier or faulty, we will either issue a replacement or refund your item(s) free of charge for you. The 4" hose enables connection from the inside of the wall vent to your appliance and is bundled with a 5" to 4" reducer and 6" to 4" reducer to ensure a secure fit to your 5" or 6" air conditioner vent hose outlet if needed. If it is too small it can compromise your household cooling system and result in inefficient air conditioning.

When I bought my portable air conditioner a few years ago it came with all the bits and pieces to frame and line a suitable hole in the wall to "plug" the exhaust hose into.
