The running costs of around 25 to 35p per hour will seem reasonable value for money the next time temperatures rise. Most have a Class A energy rating. Hi John, these new mini splits like the Gree Sapphire line have an astonishingly high SEER rating. You got the correct watts per hour there (236.842W). This is based on the SEER rating; SEER rating is a weighted-average efficiency that presumes that the unit runs at 58% output. So, at full power (100% output), you are going to see about 408W power draw (also be careful about start-up wattage for use in RVs). Designed in Guildford and manufactured in China, Meaco’s MC9000 is intended to cool rooms of between 16 and 26 square metres. Given that the average new-build UK living room is a little over 17 square metres in volume, that makes this model a prime candidate for most homes.
Not too big. Obviously, you don’t want a 14,000 BTU window air conditioner for a small 12×12 room because it unnecessarily boosts your energy bill.Example 1: What is 1 ton AC wattage? A 1-ton air conditioner (12,000 BTU) with a 10 EER rating has a 1,200 wattage. This unit is auto-evaporative and recycles condensation to cool its components, which results in infrequent drainage. That’s a good thing, too, because the supplied drain hose on my unit didn’t actually fit the outlet. Wait, there's more! Midea U comes with a built-in Wi-Fi module that allows it to connect to your smartphone or a voice control unit, like Alexa or Google Assistant. Window and portable AC units can be small enough to generate as little as 8,000 BTU. That’s why they are perfect units to cool small to mid-sized rooms. The 3 bedrooms, bathrooms and hall can be closed off by a door. The 23×12 master is at the end of an approx 75sq ft hall, I definitely want a unit in this room. Each bedroom to either side of the hall measures 13×13. Will a solo mini split unit in the center master cool the 2 side bedrooms at all? A 12k 22 SEER or a 18k 20 SEER is too big for that room alone unless the unit will actually reach to include cooling the 2 side bedrooms. An alternative option is the 27k 22 SEER 3 zone unit, with a 9k handler for each bedroom, likewise seems more than suggested for the per room sizes but is the lowest btu multi 3 zone unit. But it is true the home has no insulation and long thin glassed windows, perhaps higher btu are needed. What would you suggest?
Looks don’t make the machine, but they are a consideration with portable AC units. The SereneLife is fairly inoffensive and looks like a generic modern appliance. You decide if that’s good or not. HomeLabs doesn’t lose to the other window models in energy efficiency. As an Energy Star-certified unit with a 12 EER rating, it won’t result in a big bump on your bills. Example: How many BTU do you need for a 20×20 room? For a 20×20 room, you need about 10,000 BTU of cooling output. The inverter compressor provides excellent, fast cooling while consuming very little electricity. Unlike a traditional unit that cycles on and off, this inverter AC runs constantly at varying speeds. I have an open plan living room to an occasionally used kitchen, it’s a longer shape with a square footage a little under 300 sqft. There’s a door usually left open to a bedroom (about 110 sq ft and with its own A/C), and another to a <100 sq ft bathroom which can’t really be cooled except for whatever flows in from the living area. Ceilings are about 10’, and one wall is almost all windows – about 75sq ft of glass. It gets incredibly humid in the summer (90%+) but the windows are north facing and direct sun exposure is not excessive.Now, the key question is how much bigger AC unit can I buy and still avoid ‘cold but humid’ conditions due to oversized AC. Truth be told, that’s really hard to show for sure. The rough consensus (a rule of thumb if you will) is that AC shouldn’t have 30-40% surplus cooling output. Example: If you need a 10,000 BTU unit, buying a 14,000 BTU unit is a bad idea (you will have humidity problems). Example 2: What is 1.5 ton AC wattage? A 1-ton air conditioner (18,000 BTU) with a 10 EER rating has a 1,800 wattage. Nonetheless, as far as energy-efficiency is concerned, the 8,000 window AC units have an edge over portable ones. How Big Of A Room Will 8,000 BTU Cool?
The main reason why the LG LP0817WSR is considered the best 8,000 BTU portable air conditioner is the legacy that the LG brand brings. They have a good reputation as a reliable HVAC producer; LG air conditioners are the ones that last the longest.

The cooling output of portable AC units generally falls short of their window counterparts, but this air conditioner impressed me. The B+D unit blows out a lot of cold air and can effectively cool down a 350-sq-ft room.
Great Deal
