It was easy to assemble and I'm not a fan of constructing flat packs of stuff of any kind. It's an easy plug and play and can adapt to window use easily but I have it working with a door with a curtain and it's working really well, it's pretty powerful and has really good air flow and immediately cooled down a really hot room that's operating a pc. My pc isn't over heating anymore, it's very smooth and worth the money tbh. It's not that loud you can sleep with it on and you forget it's there when you're concentrating on something else.

I have had my unit for approximately 1 year, the Unit is now starting to let of an awful smell when in use. Is there any reason for this? I clean the filters regularly.

This air conditioner saved me from hot nights. Has been great but last week started leaking. No where does it say you need to drain it because it’s self evaporative. I woke to totally saturated carpet in the bedroom. Had to buy a stand to put it on and buckets below. Now it seems after a few days it doesn’t leak as much in the bucket.
Also the service dept I called were quite hopeless.

has Anyone else on here had problems or know why the aircon drops in and out, one minute it would be cold as than the next it’s like the fan is only working.. if anyone could help me out that would be sweet.. thanks

I purchased the Rinnai RPC35WA in October 2016 at the Good Guys and couldn’t be without it. It is absolutely perfect for my bedroom and I never had any problems with it. But after over 3 years the inevitable happened, the hose needs to be replaced but I have a very hard time getting one. As I have a heart condition It is really important that I get a replacement straight away.
Please let me know where I can purchase one.

I bought the big one by reading reviews here and I'm happy with my choice, it's very good and cool the living room very well. I think the noise is fair as everything of a normal AC is in one place so it makes noise :D

In my small 4 x 5 bedroom it cools and dehumidifies very quickly to take it down from 37 degrees, to a more manageable 27 and the added benefit of the sleep setting, means no bright display when trying to sleep at night

The window mount for the exhaust pipe literally melted from the heat after only 1 or 2 weeks of use approx 3 hours a day.
Can't find replacement, as others have said unless I pay an exorbitant price. Now it's basically useless. Pretty unreal that a simple spare part is so hard to acquire.

Before I bought this unit, I read the review here. Majority of the review is good. Indeed it is as good as it says. Unfortunately it is not reverse cycle and the cable length is slightly shorter that what you would expect. It cools reasonably well. I have yet to test it on a very hot summer. So far its performing well. It is only slightly louder than a pedestal fan when the compressor is not running, but when compressor is running, its abit louder than you might expect, which is normal.

Edit:
- Customer service is very helpful and I am very satisfied with the product.
- At full blast, its actually quite loud.

I bought this unit a month ago and am very happy with my purchase. It is a little noisy as all portable units are but otherwise works well. It cools the room nicely and keeps it at temperature all night long.

We've owned this model for a couple of weeks and are fairly happy with it. We have solar power, so can measure how much power we are using each day and this Rinnai model is notably cheaper to run than our other portable air conditioner, which is a different brand. It cools one to two rooms well and works particularly well on the dehumidifier option. However, it is notably noisier than our other model when the compressor comes on. There is also no way to easily have the cold air blow directly on you, as for some curious reason, the airflow comes out of the top of the unit. Still, it cools well, so we will learn to live with these problems. Just don't buy this model if you want the quietest compressor. There are quieter units out there.

Neat design, a little bit noisy when everything gose quiet and sleep. Every half to one hour we have to clean the water out otherwise the air con stop generating cooling air. The water must be pumped out at the very bottom of the machine so we have to stack the machine up to be able to let water fully flow out.

Overall, I'd say average.

It’s design is good, but the most important things to me when looking for an air conditioner: ability to cool, noise levels.
If you have a bedroom you want to cool down, this is the machine for you. Make sure you know the space you need to cool before deciding on which machine you need. This machine allows you to sleep well through those hot summer nights, however you may need ear plugs if you are a light sleeper. Additionally the unit slides quite easily around rooms and did an admirable job cooling down our open space living room & kitchen within our apartment. I’d recommend this machine!

This airconditioner is the best it gets cold instantly and my bedroom is so cool i turn it off after 10 minutes i would not have survived the 40 deg summer without Rinnai 3.5
Anyone looking for a portable aircon thats not noisy and has various options go for this great brand

Dont even think of buying this unit, I have similar experience as others buying spare parts. Its very stressful and currently Reccee Plumbing are re-seller for spare parts and I have been quoted 210$ Windows Slide kit. I am now with useless unit and will to search if I can source other company's air conditioner spare parts that can be used.
