Product Information

Hello Ruth, for 850 sq ft you would need a 17,000 BTU device and 6,000 BTU device for the 300 sq ft room. The best option would be to use a 2 zone mini split AC unit (1 outdoor unit with 2 indoor units, one in each room). 2 zones should have a capacity of 17,000 BTU and 6,000 BTU respectively. Such a combination, quite frankly, is hard to find; the most common 2 zone unit is 12,000-12,000 BTU. Reply Answer: Using the EPA’s 20 BTU per sq ft rule of thumb, the room size of 12,000 BTU air conditioners is 600 sq ft. Equally, 1 ton AC room size is about 600 sq ft.

I am researching the most efficient portable room air conditioner for a 2nd floor, sunny bedroom. The 13’2” by 14’5” bedroom room has cathedral ceilings, a SW facing window that measures 48” by 56” and one occupant. Due to HOA restrictions and a sliding glass window, I plan to get a portable air conditioner. I’ve read about dual hose conditioners and not sure if that’s the best way to go. I’m not sure how to calculate the necessary BTU’s needed. Can you help with any thoughts on this? Thank you, Sue Harig Reply 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?

Hello Meg, the total area to cool down is 560 sq ft. According to the EPA, you would have to multiply that number with 20 to correctly size your air conditioner unit. Of course, other factors such as sun exposure and your location can significantly increase the size of the AC unit that would be most appropriate. My girls just moved into a small 2 bedroom house without ac. We need to decide on portable ac or a window unit. The wall ac just died since it is 13 years old and landlord isn’t going to replace it, so, it is up to me, but all i see are window ac units and 5,000btu is too big for the wall opening. Reply Thank you. This information was actually pretty insightful. I live alone in a somewhat big house and there are many times I simply want to cool one or two rooms, especially my bedroom. And it doesn’t make sense to cool the entire house, just so I can sleep comfortably. I hate throwing money at the power company for rooms I’m not using.

There is also a difference if you live in Texas or New York. The local climate in Texas is, on average, hotter, and therefore you should need an air conditioner with a few 1,000 BTU more. When you like to cool a room, you should pay attention to the technical features and energy consumption. Therefore, on Klarstein you can buy an air conditioner that is perfect for use in your home, caravan, or weekend cottage. What does BTU mean? Hello, I live in Southern California my master bedroom is 15×20 with 9 foot ceilings it is connected to a master bath which is prob 120sqft my central ac does not coolAnything of a nature that for hygiene or associated health and safety - this includes the Outdoor Spas, Mattresses and Divan Sets I have a 15 ft by 15th room with a 9ft ceiling. This room has a door way that goes into another 12 by 13 room.the door way is average size. What btu would you recommend.thank you for your time. Reply I’m never quite sure if the spirit of the advice not to oversize is not to say install a 30,000BTU unit when you needed a 6,000BTU but perhaps there is much less harm if you install a 15,000BTU when you needed a 10,000BTU? Do you have any thoughts on what a safe buffer/range is if you’re trying to balance different operating scenarios?

BTU meaning: British Thermal Unit or BTU/h is a unit that determines the cooling/heating power of an HVAC device (air conditioner, furnace, etc.). Hello Edward, you’re correct, the 5,000 BTU unit is not enough. 23×25 master bedroom is 575 sq ft. Given that you’re in sunny California with 3 windows, even the 8,000 BTU might not be enough. For your situation, a 12,000 BTU or even 14,000 BTU would be recommended. Reply I have a bit of a complex room I am looking to install a window ac unit and was hoping for some btu guidance. As recommended by The U.S. Department of Energy, the ballpark figure is 20 BTU per sq ft. That is a very good estimate already.Keep your home nice and cool with the 7000 BTU Air Conditioner.
