Hello.

I have just had a portable air conditioner delivered which is fantastic, I got it from a UK company called B&Q and it's a 10,000 BTU. It arrived with a 1.5metre exhaust hose which isn't long enough, currently, we have it working by it going round another door and the hot air going into another room which has a window open (not ideal... ).

Is there a way these exhaust hoses can be extended? I realise they're just like the tumble-drier exhaust hoses and are extendable to what you want, but we need it to be ideally 4metres long.

Can you advise any places you can order it from or so forth? I have contacted the supplier but they normally take a while to reply and thought this would be an ideal place to ask!

I've done some research on the Internet and found answers such as these (so it must be possible):

How can I extend the exhaust hose?

You may purchase more exhaust hosing at your local hardware store and either replace the hose entirely or connect the hose provided with the portable air conditioner to the new hose. The new hosing must be the same diameter as the exhaust hose provided with the unit. If you cannot find a similar hose, plastic piping can be used. However, you should note that the longer the exhaust hose gets, the less efficiently the portable air conditioner will cool. Generally speaking, you should avoid making the exhaust hose longer than 9-10 feet unless you devise some sort of exhaust fan to help clear the exhaust hose. Also please note that any 90° or greater turns in the exhaust hose substantially decrease the effective length of the exhaust hose.

And a few other sites with similar replies.
Just to mention, I'm in the UK.

Many thanks.

I don't quite understand how the thing works. Does it set out in a room and blow the heated air out the hose to the outside somehow? Do you have stores that sell dryers and exhaust hose for them? I could go to Lowe's or Home Depot and choose from several styles of exhaust hose. If you such similar stores, you should be able to find what you need. For a light duty job like that, you should be able to solve any connection problems with duct tape.
