However, they can last a long time. Good quality, well-looked-after units are able to last for five to 10 years. If you want to be really specific, you can work out how many BTUs (British Thermal Units) your air conditioner requires to cool your office or room. There are handy calculators that can help you work this out online — we found one at www.aircondirect.co.uk. Do you need to clean your air conditioner? It’s an effective cooler, taking a 25°C room to 21°C within half an hour, and to 20°C over a further 30 minutes, after which it kept the temperature steady for another hour. Testing in the middle of a heatwave, this was sweet relief. However, take any claims of silent running with a pinch of salt; noise levels hit 52dB at full tilt, falling to 46dB once the temperature had stabilised. Power consumption can also reach 620 to 820W when the unit is working hard. It isn’t the cheapest PAC to buy or run, but if you need some serious cooling, it’s exactly what you need. Hi George, I can imagine that the combined 6 tons of cooling is not nearly enough. There are a lot of factors here but if we just use the main two of them: 20 BTU per sq ft rule of thumb and number of people. You have 9 ft ceiling height, which would yield a 22.5 BTU per sq ft. For 3600 sq ft, that’s 81,000 BTU or 6.75 tons. The current Mr Cool mini splits could handle this room, if it were empty.

We want an air conditioner that has just the right amount of cooling effect. That’s why by knowing the square footage of the area we want to cool down, we can calculate how many BTUs should our air conditioner have. How often you use your air conditioner will also have an impact on how long it works for and, with us Brits usually only making use of them during the summer months, this time could be stretched out. How to clean an air conditioner Pros: Easy set-up, quiet and effective, good temperature control, works as an air conditioner and dehumidifier Now, if dehumidifiers don’t help, you have to get a bigger or additional AC. This is the step you want to avoid at all costs since it’s the most expensive solution; so, installing a dehumidifier is the most optimum next step here. Hope this helps. Reply They feature a compressor in its outdoor unit that circulates the refrigerant and turns it from a gas to a liquid. That liquid passes through coolant lines to the indoor evaporator, where it transforms from a liquid to vapour. Heat is removed from the surrounding air and cooled air is blown into your home.

Now, this didn't work in every window; the hose couldn't reach the tilt-only windows in the flat we tested it in, so it had to go out of the French windows on the balcony. As I’ve never had a/c it’s hard for me to imagine one handler cooling several rooms, even with the appropriate btu’s for square footage, thank you for your help! Reply Choose a suitable model for the size of the room Those with a lower BTU in a large space will have to work harder to cool it, which is going to use more electricity.

Obviously, the relatively low BTU rating puts it out of contention for larger rooms, let alone open-plan living spaces, but for the average UK living room or bedroom it should be fine. You can control it using the top-mounted touch controls or bundled remote, and there’s a 24-hour stop/start timer to cool your bedroom before you go to sleep. The only problem is that most users describe it as “pretty noisy”. You might not want to leave this one running overnight.Air conditioners cool the air, lowering the temperature of the room, but they also lower the humidity, so can be drying, whereas air coolers add humidity to the air. Appearance-wise, the device is compact, measuring just 20 x 20 x 25cm and we love that the unit sat neatly on our desk without being too much of an eyesore, while the LED light is a lovely touch and there are a selection of colours to choose between. What size air conditioner you opt for depends on a variety of factors, one of them being the price you're willing to pay. Mini-split AC units. Example: Mr Cool mini-split units have the highest SEER rating of above 20 EER.
