10 000 btu what does that mean

Your site has given me a lot of ideas… but not fully addressing my specific need. There are shaded non-glass windows tax reasons on two of the four walls. In a normal situation, a 6, BTU would suffice. You can check out the LG unit in our list of the best thru-the-wall AC unit. The master bedroom is on the 2nd floor, sf, including the bathroom.

That area is about or sf, with many windows and a cathedral ceiling in the living room up to 25 feet or more. Any advice? Anything we need to be aware of for electrical systems? Or single vs dual hose units? Thanks for your help! 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. For that you would need somewhere between 40, and 50, BTU; depending on insulation, sun exposure, and so on.

Obviously, dual hose units are better higher efficiency, lower long-term costs; based on EER rating. That just might be sufficient given your in the northeast US; your calculations are again on point. You might want to check out our article about the best dual hose portable air conditioner here ; you will find very efficient 12, BTU and 14, BTU units with a very good reputation. Overall, you do have a remarkably good eye for these BTU calculations and the general layout of portable AC units.

Cool DIY mini split configurations. My home is years old, 8ft ceilings, mostly shaded except along the south facing side, located in Los Angeles. Dining area and kitchen along the sunny south wall. The 3 bedrooms, bathrooms and hall can be closed off by a door. Will a solo mini split unit in the center master cool the 2 side bedrooms at all? 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 Deborah, that was quite a read. Two indoor units here are minimum; a 3-zone mini-split would be the most optimum option.

You can check the best three-zone mini-split systems here ; Senville units, for example, are both cheap and highly efficient. Total BTU output of 36k seems to be a good estimation. Having 3-zone mini split, or even 3 individual 12, BTU Mr. Cool DIY units would be most optimal. The source of sound in portable AC units is compressor and airflow. You can see that very well in our article about the quietest portable air conditioners. I have a bit of a complex room I am looking to install a window ac unit and was hoping for some btu guidance.

It is a square foot bedroom with 8 foot ceilings. There is also an additional raised platform space that is about 4 feet high from the platform to the ceiling and is inches wide and 27 inches deep. The building is a townhouse with 3 floors and the room is on the 3rd top floor and is directly under the roof which gets the hot sun of San Diego.

The bedroom also has an attached bathroom and is the only thing on the top floor next to a very small hallway up a flight of stairs. This is also the only room in the house that will have an ac we are renters and that is nonnegotiable at the moment and the house in general and especially that room gets quite hot in the summer. As far as I can tell, based on square footage alone I would be looking for a btu unit, but I am wondering if might be better given the location of the room and those additional factors.

I definitely do not want to cause moisture issues by getting too big a unit, but do not want to undersize and have a unit not work either. It has 2 one exterior doors, 6 windows, and 2 skylights. There are 3 oaks but midday does get a lot of sun through the skylights.

Live in Savannah, GA. Hello Steven, patios are notoriously difficult to get a good BTU estimate. The exterior wall faces west with 2 standard and 1 double window. There are doors to the bathroom and hallway but I keep them closed at night. I also keep the blinds drawn all the time but even still it gets hot from the afternoon sun and can be uncomfortable later for sleeping. The calculators seem to point to the btu unit being sufficient but I would love to hear your thoughts.

Hello Steve, the total square footage is sq ft and you have an above-average 9 ft ceiling. For a standard room, 8, BTU could be enough. However, the west-facing wall, hot bedroom, and so on do indicate that you would need something a bit more powerful just to be safe. It does help and thank you for the reply. I was thinking that the 10, unit was the better choice but then got worried about all the warnings about having a unit too big causes.

The Midea looks like a really slick air conditioner. Thanks for your feedback on it. Thank you so much for doing this. I wanted to follow on from an earlier question where you advised the extra BTU is not necessary if you are not an active user of the kitchen.

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.

There are different ways to cut this where I could calculate anything from 7, to 15, units, but am considering to go with a 12, unit on balance. Does this seem reasonable? All your presumption about oversizing a unit, short cycles, wearing out, higher bills are on point.

Hope this helps a bit. For the kitchen, you should add an extra BTU due to high-temperature devices. We have a sq.

Casement windows are along the full wall in the living room and a sliding door in the kitchen — east exposure. Both bedrooms and bath located between the two bedrooms are west exposure with large double hung windows.

The cabin is divided equally with open kitchen, dining and living room on one side. The center of this area leads to the other half of the cabin with both bedrooms and bath — west exposure. Our temps in the summer can be in the upper 80ss with high humidity.

With sq. Hello James, in-wall AC units are quite popular in the Northeast. Despite little insulation, this is still Minnesota. If you need some ideas, you can check our article about in-wall ACs. I am looking to cool down a room that is 12x10ft with 9ft ceilings with one window that gets the sun in the morning, for two people sleeping and living in it.

You can check some of the smallest air conditioners on the market for 10x12ft rooms here. Hi, Thanks for your website, you are a real life saver!

I am tired to install them 3 each year. One BTU in my bedroom 14X10 ft with 8 ft ceiling, window gets the sun in the afternoon. One in the living room BTU I was thinking of a BTU in my bedroom and a second unit for the rest of the apt. I am afraid that with one unit only, my bedroom wiill not be cool enough and the living room will be like a freezer.

Also , which brand is the quietest. What is the max DB I have to check to be sure it is quiet. Thank you so much for your input, very helpful. Hello Monique, thank you for the question.

Noise-wise, the quietest portable ACs have the highest noise levels of below 55 dB. This comment section is fabulous to get feedback! Hello Anthony, thank you for your compliment; we do try to help everybody out.

As far as your situation goes, the 4, BTU for the kitchen but you do have a refrigerator there; adding 1,, BTU is reasonable. For the living room sq ft, 9 ft average ceiling height , you would need about 7, BTU. For connected sq ft bedroom, additional 3, BTU. If you find it useful, you can check out the best 12, BTU air conditioners here.

Do keep in mind that if you choose a window AC unit, you have to — due to regulations in New York City — also have a support bracket for window AC units. Thanks for this!! Will there be a detriment if i go up one step more and go 14k BTU? Trying to work out what is overkill and what is not. Now, those are some impressive keyboard skills!

Never seems so astute a sketch with just a keyboard. Of course, you can go with a 14k unit as well. We have a 2, sf home in the upper midwest. The first floor is about sf with 9 ft ceilings. The second floor is the other sf with 8 ft ceilings. Our south facing windows are about sf and north facing are about sf. We also have an extra refrigerator and a freezer along with the usual appliances. We estimate we would need a 4 ton AC unit. We are wondering what you would estimate with this info.

Hello Shel, thank you for all the specs. To get a bit of information, you can check how much 4 ton central AC units cost here. I have a complicated air conditioning situation. I live in southwest Missouri, with a hot, humid climate in the summer.

The house, which I grew up in, is a one-and-a-half-story s Craftsman-style house not true Craftsman , with central air. Like my father, I keep the door at the bottom of the stairs closed to save on utilities.

The upstairs consists of two bedrooms, which are divided by a hallway, which gives onto a stairwell from the gabled landing. The bedroom doors face each other, and the two windows in the south bedroom more or less face the single window in the north one.

When my dad first put in central air in , he bought me a Carrier Siesta II, 8, BTU unit which has since literally disintegrated for my bedroom measuring about sq. When my brother came to visit in the summer, it had to do for both bedrooms and the hall. The former was a 2. 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, BTUs? Hello Julie, sounds like a lovely house.

Given that you have a problem with high humidity, a 12, BTU unit would be even better, however. Given your situation, a 12, BTU unit with the highest possible dehumidification rate would be the most optimum and adequate choice. Hope you find this helpful.

Great article! But I am still doubting myself. The ceiling and walls are insulated. The building gets sun for most of the day. No stove or oven, but there are several arcade games and pinball machines that generate some heat, though not nearly as much as an oven. I was thinking a 24, btu single zone minisplit? Or would 18, be sufficient.

Would like to keep the building at in the summer. Considering good insulation, 18, BTU should be sufficient. Thank you so much. The heater is useful in the winter but it can serve only as supplemental heating; not the primary heating system.

All 10, portable AC units that generate less than 57 dB are considered quiet. They have a good reputation for reliability. This is a classic 10, BTU window air conditioner. That makes it very energy-efficient with an Energy Star rating, of course. The total CEER rating is On top of that, it comes with a WiFi connection; you can connect and control it via your iPhone or Android device, or even via Alexa.

You cave 3 fan speeds low, mid, high and a 2-way direction airflow; the air filters are included. All in all, if you have to trust one brand, the GE is definitely the one. The drawback of this more classic model is average-only energy efficiency. With an EER rating of 8.

The noise levels, however, are sufficiently low. With the max. Everybody loves an LG air conditioner. How big of an air conditioner would I need to cool a house with 5 bedrooms a kitchen and dining room and how can you tell if its a or a unit. A sqft house is usually good with a 5 ton ac. My apartment faces the sun and it stays hot even during the winter if the sun is out.

I hardly get any air in my bedrm. I previously had a 12, btu which just gave out after 10yrs. Would a 14 or 15, btu work better. In need of a new one. Please help. Thank you in advance. I know that the BTU is a unit of energy and that even if a candle is left on long enough, it can deliver any amount of BTUs. The article actually covers this at the beginning. It can be easy to gloss over if you already know what a BTU is before reading. A candle will not raise the temperature of 1 pound of water, 1 degree Fahrenheit at sea level because the heat from the candle will dissipate out of the water faster than it will raise the temp.

So 5 bedrooms kitchen n dining are.. Hi, need your help regarding below. When you count calories, you're keeping track of how much energy you put into your body and need to burn off to maintain your current weight.

When you count BTUs, you're keeping track of how much energy your appliance can process to heat or cool your room.

As mentioned, BTUs measure the amount of energy it takes to produce a certain amount of heat. When it comes to an air conditioner or heating system, the BTU rating tells you how powerful your appliance is. For example, a heater that is labeled as a 5, BTU heater can produce 5, BTUs of energy over the course of an hour.

A heater with a higher BTU rating is more powerful — that is, it has a higher heat output — than one with a low BTU rating. It can do more to raise the temperature in your room each hour, so you can either heat a room more quickly or heat a larger space. BTUs are used to measure energy in relation to heat remember, it originally comes from talking about heating a pound of water up , so it makes sense to label heaters this way.

But what about air conditioning? In this case, you're trying to cool a room, so how do BTUs fit in? Air conditioners actually work by removing heat from a room, rather than adding cool air. This is enabled by the compressor system, which uses a chemical refrigerant to absorb heat and then carry away from your room, where it is released into the outdoors.

In this case, BTUs aren't a measurement of how much heat is added, but rather how much energy it takes to remove the heat using the compressor system. It still takes energy to do this, so the BTU is a measure of this energy rather than of direct heating.

As with a heater, high BTUs on your air conditioner means that it has a bigger capacity to get its job done. If you're looking to compare cooling output for similarly priced air conditioning units, looking at the BTU rating can give you an idea of which one is the most powerful and will give you the biggest bang for your buck.

BTUs are a very important factor when it comes to choosing the right size heat pump, space heater, or cooling system for your home.
