Thank you for the useful advice. My small apartment has openings in the wall for AC in the living room and the bedroom, thus I am debating whether to get one 14,000 BTU AC or two smaller ones. Any advice on the subject is appreciated. ReplyHello there, if you need 14,000 BTU AC, one window unit or one mini-split unit would be the best choice. AC units above 15,000 BTU usually need an electric upgrade; which you won’t need here. On the other hand, you can invest in two portable AC units, each of 7,000-8,000 BTU, but those can take some space and need to be vented out of the window. The most elegant solution would be a 14,000 BTU mini-split unit. Reply The living room unit is 6,500 BTU and the bedroom unit is 6,000 BTU. I use them only for those rooms. The BTUs are more than adequate for the spaces, but the units are too old to work properly and need to be replaced. Which rooms are next to, below and above the room to be cooled? For example, are there rooms that give off a lot of heat? My question relates to how the kitchen bump up intersects with the common advice that if you oversize your unit, then it can lead to short cycles that leave you with humidity and wear out the equipment. No article online seems to makes clear how much wiggle room you have before that might happen, and often it’s simultaneously encouraged to go one higher than you need. Hence this 4000BTU kitchen bump comes to mind and whether that’s enough to amount to a harmful oversize during the majority time the kitchen is not used. Hello M, nice plan. Your calculations for the master bedroom with bathroom and another bedroom sound about right. The cathedral ceiling open concept area is fun indeed. 🙂 Calculating the full volume of that area is a bit complex. Let’s simplify it a bit; a 1,000 sq ft area with 16 ft average ceiling height. For that you would need somewhere between 40,000 and 50,000 BTU; depending on insulation, sun exposure, and so on.

The horsepower hours unit number 0.00039 hp h converts to 1 BTU. somehow equates to: 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.

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. Given these this range of uses–one for the whole upstairs and one for the south bedroom only–do you think I need a unit with more than 10,000 BTUs? For several reasons, I’d rather not install a unit for each bedroom.
