A (cloth) window sealing kit is included with the Princess air conditioner and the smart device also has a water tank indication. Now, you can see exactly when the water tank is full and needs to be emptied. Do you also long for cooling and more comfort on hot summer days? Then this elegant Princess 352900 Smart Air Conditioner 9000 is exactly what you’re looking for. The smart air conditioner with a cooling capacity of 9000 BTU is not only easily operated with the control panel and remote control, but also via the HomeWizard Climate app and voice control. On top of that, it has a hidden display with touchscreen that is only visible when the device is in use. This air conditioner can be operated via the HomeWizard Climate app. This app is available for Android and iOS and works with Google Assistant and Siri. This way you can control this Princess air conditioner from anywhere within your living area and when you are not at home. You only have to connect the air conditioning to your Wi-Fi network and then you can be sure that you will come home to a fresh home in the hot summer. A portable air conditioning unit will simply move from room to room instead of having a device mounted to just one wall in the home. Energy use and environmental impact are also worth considering. While modern AC units no longer use ozone-damaging chlorofluorocarbons (CFCs), they do sap a lot more power from the grid than a humble fan and that means slightly higher leccy bills and hence more pressure on the environment.

This gutsy 12,000 BTU unit has an air flow of 380m³/hour so it’s good for rooms up to 100 m³. It even has a dehumidifying function. Given that it’s 25˚C outside right now, I hastily got it out of its box (which lifts off to expose the unit underneath) and wheeled it into the lounge where I conveniently have a wood burner to position it in front of, obviously with the burner’s door open. If you don’t have a fireplace to hand, the product ships with a 1.5m concertina hose to port the warm exhaust air either through a hole in the wall or a partly opened door. Alternatively, you can use the supplied universal window kit to seal the area around the hose outlet but this always looks a bit Heath Robinson-esque to my mind. No responsibility is taken for the correctness of this information. The listed offers do not constitute legally binding advertising claims of the merchants. Even without its cooling ability, this is a decent fan. It’s fitted with louvres that offer automatic horizontal oscillation, and manual adjustment of vertical wind direction. At the top, a touch-sensitive control panel lets you choose from three fan speeds, and three modes. You can switch the cooling or oscillation on and off, and set an auto-off timer in one-hour increments up to an unusually long 24 hours. With this Princess air conditioner you can cool and dehumidify your home. Thanks to the adjustable fan speed, digital timer and swing function, you can set this air conditioner exactly to your own wishes and needs. The air conditioner also has a convenient "Fan" mode. Is it always so hot in your bedroom during the summer? At night, set the Princess Air Conditioner to "Fan" mode and enjoy a nice breeze while sleeping.As is the case with every portable air con unit we’ve seen, it comes with a concertina tube to the expel the hot air it creates and, in this case, a special window kit designed ostensibly for sliding windows or doors. It also comes with a remote control. This elegant Princess 353200 Smart Air Conditioner 12000 has a hidden display with touchscreen that is only visible when the device is in use. This smart air conditioner with a cooling capacity of 12,000 BTU is not only easily operated with the control panel and remote control, but also via the HomeWizard Climate app and voice control. This isn’t a noisy fan, but at higher speeds its whine is a little intrusive. I measured a minimum sound volume of 27.2dB, from a metre to the side with the fan at its lowest. My highest measurement was 67.7dB, taken from 15cm in front of the grille on medium power.

This modern and minimalist designed device has a hidden display. This means that you cannot see the display when the device is not in use. This results in a stylish and sleek appearance. A (cloth) window sealing kit is included with this Princess air conditioner and the smart device also has a water tank indication. This way you can see exactly when the water tank is full and needs to be emptied. However, it’s very important to note that that’s much less you’ll spend to run an air conditioner. A powerful modern example might consume around 1,100W when working hard, costing around 33p an hour on the same 30p/kWh tariff.

And whilst the UK isn't exactly the renowned hub for sunny weather - it's not a bad thing to be prepared for the warmer weather. For customers who suffer with night sweats, an air conditioner with adjustable cool settings could be a nice touch for a more comfortable night's rest. The type of air conditioner you buy depends on the size of the room you want to cool. Anything below 8,000 is likely only going to cool a small/personal space, whereas 9 -12,000 BTU’s can usually cool up to 25 square metres. This air conditioner with a cooling capacity of 3.5 kW is very economical in consumption and labeled with the energy label A. In addition, you will certainly not be bothered by the noise of this Princess Air Conditioner because it only has a noise level of 65 db. This powerhouse with a power of 1346 watts is suitable for a range of 100 m3 and easily cools your living-, work- or bedroom. Portable air conditioners are rated in British Thermal Units (BTUs) the higher the BTU, the larger room it can dispense cool air for, anything below 8,000 BTU is likely best for a small room. Many air conditioners also require outdoor venting system to really operate properly.

This is a very powerful air conditioner, and if you leave it on for long enough it can make even large rooms feel very cold – but the heat hose can get awfully warm, so you want to make sure it's going out of the window so it doesn't undo the Chillflex's hard work. The quoted 64dB is fairly average for air conditioners, and sleep mode takes it down to just 52db.Cooling aside, this is a surprisingly powerful fan for its size. Just 15cm away from the front grille, I measured a wind speed of 5.2 metres per second (m/s) on the lowest setting. This rose to 6.6m/s on medium, and a very punchy 7.7m/s at full – that’s equivalent to 17 miles per hour. This 80cm tall air con sports a cooling capacity of 10,000BTU and is recommended for rooms up to 23m². It also dehumidifies the air in the process removing up to 32 litres per hour. Its digital interface and included remote control allow access to all main functions: temperature, fan speed and timer. I can also be used as a simple fan.

We tested it with the rear exhaust port positioned in front of a fireplace flue rather than a window, and it worked impeccably well. Sitting two metres away, it was like being in a car with the air-con on full bore. Indeed, I had to raise the temperature setting a few degrees for fear of freezing to death. If you’re likely to use the air conditioning unit whilst you’re asleep, it’s worth looking for one with an operating noise level of 60db or under. How much should I spend on an air conditioning unit?The AEG Chillflex Pro is a great choice if you want maximum cooling with minimum hassle. It comes with a 1.5m exhaust hose, 63cm drainage hose and a remote control, and with 12,000 BTU/h it's capable of cooling large rooms without too much effort. It's one of the heavier air conditioners you can buy, although it's on wheels so it's easy enough to roll about, and you'll need to get a window kit separately as AEG doesn't include one with the product. There's a programmable timer and a sleep mode function to reduce the noise at night, and the refrigerant is R290 which has a lower environmental impact than the more commonly used R41A.
