What do the various BTU's support room size? We have a 15x15 room.

In considering the size AC unit you need, the first thing to look at is the climatic region of the country in which you will use the system. If you are on the same latitude as Burlington NC our summer design is approx. 92 Deg. F. So it is considered middle of the road for the design of most units. We actually have a high humidity issue occasionally. The next thing to consider is the amount of radiant energy the room is exposed to, which you could call the solar(sun) exposure, first the total of perimeter walls in square footage and then the amount of glazing(window) square feet, as well as the R value rating of the windows. Next is the ceiling height, because with the mini-split units they are installed within 12 inches of the ceiling. To help you get a more practical overview. All these things will help you determine if you can stay with the basic manufacturers room size rating or have to get a little larger unit.

Well, it depends. How well insulated, how much air infiltration, how much glass and it's e/r ratings and exposures, etc. Rough rule of thumb would be 400sq-ft/ton 12000BTU/ton, approximately. But that is why HVAC guys do (or should do, a lot of them just fudge it) heat load calculations. I have 3300 sq-ft with 7-tons of AC. Until it gets stinking hot, I can get buy with 4-tons, but when it is 116 outside, then that's not enough, and the HPs crank up to high. My house is well insulated, with limited E/W glass and overhangs shading the south windows in summer. But I live in AZ. Oh, yeah, humidity also matters. Well, it depends.

HiI used the u it for a medical spa room where a high power laser emits lots of heat energy. I have standard cooling but it was quite insufficient for my purpose. This suint has made it so much better for the room and my main unit dosent have to be revved up before and after the procedures. The room is about 16x16. So it shall be fine for your 15x15 room.

Usually consider 30 BTUs per square foot. But this is a general rule of thumb and many other things can effect the heat load.

I have 2 rooms like that and bought 9000 BTU for each and work good. The Rooms cool and heat fast.

BTU's for this item are 5,118; and will cover 5,000 Square Feet. I got this answer from their Customer Service at 1-888 672-5832.

There are various BTU calculators available on the internet which take into account other conditions such as insulation, sun exposure, etc. It would seem that 18,000 would be plenty even if area were poorly insulated. However, not sure how much heat your dryers produce. Also, keep in mind that these mini-splits are far more efficient than window units.

The hydronic baseboard units are rated in Watts. The 1504 model rated at 1,500 watts is roughly equivalent to 5,000 btu's, or about the size to heat an average size room (10'x15').

I don't think it will work for a room 15x15, maybe a room half that size. It fills about a cup of water every day.

if it's insulated I would go with a 12000 btu unit,if not go for the 18000 btu unit. I purchased a pioneer 18000 btu unit for a 750 square foot garage and it does the job.

I know that it can carry 150,000 to 160,000 BTU's but I don't know what the max is.

Choose between 9000 or 12000 BTU depending on your room characteristics (Use 12K if your room has extra heating or cooling loads as compared to a standard room).

bigger the better. Most of our units are 18000 btu for our coolers. these are approx 8x12x8 high. also have a 24000 btu in our yogurt incubator which is 7x7x8, this brings the temp down in about two hours. Hope this helps.

approx dimensions: h 23 w 15 d 11. This unit can be expensive to run. Be sure that you need the 30 pint capacity before you buy it. Just like an oversized air conditioner, it will start and stop frequently (thus the cost) in a space that's too dry.

I would believe this is 13000 BTU. I have the unit and it cools my 20' x20' room. I would not count on more than that for this unit.

I'm not sure about the room size. What I am sure about is the fact that the system develops wiring problems after a while. If I was you I would check out Consumer Reports magazine for a better alternative.

165,000 BTU for this unit. Im not sure where brian is getting his info but you need to know the unit BTU output to figure out the pipe size and so on. Were you able to hook your unit up? If so what size tank did you use? How long does the tank last?

To answer your question, you will need to know what BTU nuts you have installed currently, then check the chart of the kit to ensure you will be getting some smaller ones.

Hello You have to contact the customer service to let them know that you want one 18000 and two 9000 btu inside units, be careful my outside unit broke down after a couple of months, I had to call them several times after many calls they didn't want to take my calls, they sent the spare part after 6 months so it's up to you I don't recommend this company regards

My room measures 12 feet by 15 feet, comes to 180 sq. feet. An average size room. My purifier does a very good job in cleaning the air. What are the measurements, the length and the width of the room.
