MeacoMeacoCool MC Series 12,000CHR Portable Air Conditioner - Powerful Portable Air Conditioner and Heater, Energy Efficient with Two Window Venting Kits included

My office is a 20ft x 10ft portacabin which gets extremely hot and uncomfortable in the summer months--far warmer than a house. I've had three different brand air con units over the last few years, all of which have struggled to keep temps even equal to the outside temperature. This unit has managed to reduce the temperature to 21 c with an outside temp of 28 degrees. Without air con the inside temperature of my portacabin would be around 31 c. Add to that the convenience a remote control, reliable wi-fi app, heat pump for the colder days, fantastic UK build quality and a proper comprehensive English language instruction manual I'm more than happy. A little noisy yes, but they all are. Being comfortable is the most important aspect. Once in a while you buy a product which ticks the boxes and this is one of them.

noisy when cooler on , the compressor

This airconditioner does what it promises to - provide an adequate level of cooling to a 20 sqm or so room, provided that the exhaust pipe is properly installed. The major downside is that it is far noisier than the rated dBa noise level, as I noted in my review of the smaller version. The noise is such that it interferes with a conversation or watching TV.

MeacoCool MC Series Portable Air Conditioner 12000R. It was very well packaged and easy to remove from the packaging. After cutting all the sticky tape the box just lifted off the unit. Easy to understand instructions and easy to get up and running although I had to make my own seal for the window out of cardboard as I couldn't figure out how to use the one provided for windows. If you have patio sliding doors it would be fine as there is a good kit for sealing that type of door. To quote my wife, "It's good but flipping noisy". That's about it in a nutshell. We bought this just before a heat wave. I didn't have time to research portable air conditioners properly. If I had done, I wouldn't have bought it or any other make. The low decibel, 53dB is only when the fan is on low speed without the cooling compressor running. When the compressor comes on it's flipping noisy. You can't hold a conversation without raising your voices to a level that would be considered shouting and you need to turn your TV volume up a lot. The unit doesn't recirculate the air in the room. It constantly replaces it with air drawn from anywhere it can suck it from. If you close all your windows and doors as per the instructions, it will suck air in through cracks in doors, windows and in my case from down the chimney which made our room smell of soot from when we had a coal fire. From then on I just left the room door slightly open so as not to suck air from down the chimney. Do yourself a favour, before you buy one put a search in, "How do portable air conditioners work?" and have a good read. At least you'll know what your letting yourself in for. They all work in the same way. Having said all that, when it was 36C outside recently, I set it to 23C and it kept my lounge at 23C.

The unit came a day later but it's very sturdy unit very heavy and noisy but cools the air brilliantly I think it will work really good once the hot weather is upon us.If you don't like the weight and the Noise don't buy but they are all the sameThis unit is definitely one of the best in its class

This unit is very nice, easy to get going and has a number of useful window kits.

This works so well and cools down my living room so quickly . You need to read the instructions carefully before you buy it so you know you can position it in the right place for the vent to go thro a nearby window .It is very heavy so you can’t move it up and downstairs but you can move it between rooms easily . When it’s hot outside, this unit is worth every penny. I’ve recommended it to all my family .

Appears to be effective although rather noisy.
