Hello Daryl, the biggest residential portable AC units have a maximum cooling capacity of 15,000 BTU. It’s an electrical thing; if you want 15,000 BTU+, you would need 220V instead of 115V, or alternatively, you would have to double the Amps, which is not ideal. In your situation, you would probably need two units, yes. 2 x 10,000 BTU would make sense. Maybe a combination of 14,000 BTU and 8,000 BTU would be smarter; you only run 14,000 BTU most of the time but during a really sunny day, you also turn on the 8,000 BTU unit. Reply All costs includes parts, labour, call out and delivery charges, so you can rest assured there are no hidden costs. 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. Reply 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 Again, when narrowing down your choice of an air conditioner, knowing how big an area you need to cool is your best friend. Based on that, you can calculate sq ft to BTU and immediately know what range of BTU values your perfect AC unit should be.

Hello Tommy, if we apply the EPA recommendations for 8 ft ceiling we get 640 sq ft * 20 = 12,800 BTU. Now, 18,000 BTU would definitely do the job but it might be an overkill. According to the calculation, the 12,000 BTU is nearly enough. Basements tend to be colder because they have less sun exposure and are located near the ground. 12,000 BTU might just cut it, especially if you have a 7 ft ceiling. Reply Remote Control Included– Allows you to control unit when you’re not close to it. Powered by 2 x AA batteries (not included).I am building a small L shaped home. One part is 48×20 that has the living room & a small office area, 3 bedrooms, 2 bathrooms. The other part is 20×16 open kitchen/dining area. How climate is mostly in the 80s year round and very humid (Hawaii problems?) What air cooling system would you recommend. I’m also on a tight budget. Thank you for your help Reply Also I love your calculator. In most literature I see it measured by square footage per room and that it wont cool anymore than that and it wont cool correctly if unit is too big for that room. this confuses me.

Move the portable air conditioner very easily thanks to the wheels, so you can use it wherever you want. The compact size ensures that the air conditioning does not take up too much space in your room, and you also need little space to store it again after the summer. In addition, the air conditioning comes with a handy window kit, so you don't have to drill holes in the wall.

Here is an example of how you can calculate how many BTUs you need to cool down a 500 sq. ft. area with 8 feet ceilings, average sun exposure, average climate, and not including kitchen (you can find this BTU calculator below and use it for your situation; with 4,000-24,000 BTU room size table): All costs includes parts, labour, call out and delivery charges are covered, so you can rest assured there are no hidden costs. For smaller untis we may ask you to return it to our UK repair centre. When used as a fan, two different speed settings are possible. In addition, you can choose to use the air conditioning to dry the air, with a dehumidification of 0.8 liters per hour. The water tank has a volume of 0.5 liters, and when it is full, the air conditioner will indicate this itself. With this function you will no longer be bothered by moist and oppressive air! In addition, dry air is easier to cool, causing the temperature in the room to drop even faster. Cools, dehumidifies and ventilates over two-speed modes, keeping you cool during different types of heat, with an LED display for easy control Hello Missy, 8,000 BTU is the optimum capacity. The 10,000 BTU would be overkill; it would cool the space better due to 2,000 BTU more cooling power but the electricity bill and the initial portable AC cost would be higher. Reply

Hello Sue, the 13’2” by 14’5” room has about 190 sq ft. Let’s assume that the cathedral ceiling has a height of 13 ft. Such a bedroom has the same volume as a 310 sq ft room with an 8 ft ceiling height. That would, roughly speaking, require a 6.200 BTU portable AC unit. With that big sliding glass window and a lot of sun, the safe estimate for the most optimum AC unit would be 7.000-8.000 BTU.

You’ll find below a pretty handy chart that will help you pinpoint the right model. You’ll notice that room size and heat load are the two variables within this chart. Step one is simply figure out the room size in square feet of the room you would like to keep cool. Next, figure out the amount of heat or "heat load" that the room receives. For example, if the room has a lot of windows or is next to a kitchen, that room would probably have a high heat load. Pro tip: Always buy a little bigger AC unit than this recommendation. Example: When you use the BTU calculator below and get, let’s say, 10,000 BTU for a 500 sq ft area, start looking for a 12,000 BTU air conditioner. Your electricity bill will be a little higher, but you won’t need to sweat if you bought an AC unit that’s too small. 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. Hello Zeman, it’s the same for the window and mini-split unit. The mini split with the smallest capacity is 9,000 BTU; that’s why they are recommending that. If there were a 4,000 BTU mini split, that would be optimum, but they don’t make mini splits that small.

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?

Portable units running of 110/120V go up to 15,000 BTU (above that, you’ll need 220/240V voltage). Obviously, dual hose units are better (higher efficiency, lower long-term costs; based on EER rating). I tested the unit over a couple of humid days in my home office and bedroom, both of which measure around 26m2, the upper volume limit for the unit. Weighing in at 23.5kg it is – just – possible to get the unit up a flight of stairs single-handed, but nul points to Meaco for the shallow finger-grips. Should an attic or a cellar be air-conditioned? Both types of rooms have different requirements. A cellar needs much less cooling capacity than an attic. If you want to properly cool down a 300 square foot area (or room), you need a 6,000 BTU air conditioner. Obviously, the problem arises when you have a tiny 12×12 room, for example. According to the US Department of Energy directive, an air conditioner’s most appropriate size would be 2,880 BTU unit. The best you can do here is to buy a small 5,000 BTU window or a small 8,000 BTU portable AC unit (more about the smallest AC units here).
