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. The less humidity inside a room, the cooler it feels. If you don’t vent the portable AC unit, then the moisture will continue to build up and neutralize the cooling effect of the air conditioner. All VELUX Roof Windows are constructed with quality wood, not metal or vinyl. Wood is an excellent natural insulator because it does not conduct heat like metal or vinyl.

Because you can’t stop all sources of moisture in your house, ventilation is also very important. Your home needs to breathe to fight condensation. Remember that cold air can hold less water vapor than warm air, so in the winter the air outside is often drier than the heated air in your home. Therefore, by allowing moist inside air to escape and dry outdoor air to enter, you can reduce your homes humidity level. A third reviewer commented on the ease of assembly and effectiveness of the cooling and value: ‘Easy instructions - window and door kit included - easy to put together - decently quiet to run on full blast (no louder than the large fan we have running). No complaints at all - even after 2 hours running you can feel the difference in the next rooms as well. Great unit for the price.’We sell roof windows for pitched and flat roofs to bring daylight and fresh air indoors. We also sellsun tunnels, blinds and shutters. Find a solution to make your home brighter, healthier and more comfortable. Ventilation is a big step in the fight against condensation that’s why VELUX makes roof windows with several exclusive features that can help your house breathe easier.

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.’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. It's also a very affordable option compared to other models. It's not the most powerful option out there in terms of BTU, but Meaco offers plenty of alternative models, ranging from this the smallest 7000BTU through to a 14000BTU model. Design-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 Like all air con units, when in Cool Mode the air duct needs to be positioned out of the window so you’ll just need to make sure it’s positioned close enough to a window to do this.
