There are four modes – cool, fan, dry and sleep. The sleep mode reduces the speed of the fan and also the noise the unit makes – making it easier for you to cool your room and sleep soundly, however warm the night is.

Another review says: ‘Does the job, it is very loud. All sleep mode does is switch the brightness of the display down. It’s a bit heavy so not ideal for going up and down stairs but has wheels to be able to move around.’ If you can't do this, you'll have to use the supplied window ducts. You need to open a window, find the right fitting, and then attach the hose to it, dumping all that heat out where it's not bothering you any more. MeacoCool MC Series 14000 review: VerdictDesign-wise, the MeacoCool MC Series 7000BTU Portable Air Conditioner looks pretty good when assembled, although it does have a bit more going on visually than other models we tested and I wouldn't say style was one of the key elements of its design In low fan speed the sound pressure level of 53dB(A) makes this a easier unit to live with. To get the best out of your air conditioner we recommend pre-cooling rooms, for example a bedroom, before you need to use them so that the room is nice and cool when you need to use it. This makes it easier to To get the best out of your air conditioner we recommend pre-cooling your rooms – particularly bedrooms – before you need to use them. This means that your room is the right temperature, making it easier to work, sleep and live. At just 20.5kgs in weight, this is one of the lighter air conditioning units I've tested which makes it much easier to transport around the house. There’s a handy remote control so that you can keep an eye on your unit’s operation, and we’ve made sure that the air conditioner is easily portable so you can move it around your home or office as it’s needed.

The MeacoCool MC 7000, for instance, delivers full air-conditioning capabilities for less than the cost of a Dyson desk fan like the Pure Cool Me. It isn’t the quietest thing in the world but it’s a lot more effective at keeping you cool than a simple air blower. Unlike most cooling units this model can be moved alone if you live by yourself, is easy to reposition thanks to its castor wheels, and is a great slimline option to stow away in the car and take to the caravan or a holiday let to keep cool in the summer heat. The Dry setting uses the room’s ambient temperature to run the compressor and it behaves a bit like a dehumidifier, drawing moisture from the room. You can’t select a temperature in this mode because it’s all controlled by a processor. You will also need to fit the supplied drainage hose to the rear of the unit when in Dry mode so excess water can drain away. With rated maximum noise levels of 65dB in high mode and 53dB in low fan mode, the MC 7000 is noticeably louder than your average tower fan (we measured the noise levels at 62dB and 56dB respectively). There’s also a slight buzzing that accompanies the unit while it cools, too, so it isn’t the ideal choice to run overnight in a bedroom.According to the manual, the air filters must be cleaned once every two weeks because otherwise dust will collect on them and restrict the airflow which could affect the efficiency of the unit.
