Default window a/c units

Are 2 5000 Btu units the same cooling capacity of 1 10,000 unit?

A btu is a btu no matter what country you are in. Will it cool a whole house down the same ? Depends on walls

Simple answer is yes.

Two 5000 btu units may be more efficient than a single 10,000 btu unit.

^This^

With 2 units you may find a power savings due to zone cooling as long as they are as efficient as the 10k one.

Personally I'd go with the single 10K unit.

I don't know what your needs are but think about this first before buying. The 5K units are usually loud, not very efficient and with few options. They are cheap to get poor people into an AC unit.

A 10K unit will have a remote, on/off timer multi directional air flow, be more quite (generally) and I'd bet far more efficient. Think twice, IMO.

Not really true, 5K and 10K have pretty much the same SEER rating, noise and those ratings have a lot to do with the mfg.

Regardless of you buying the 5's, 6's or a single 10 if you run a ceiling exhaust fan to pull the marw air out of the house while the A/C units are trying to cool the air you'll cool the air/ space in a third of the time.
I was going to say, I have personally noticed a big difference between 5000s and 6500s and it is usually just a $20-30 or so price increase. Check out a pair of 6500s unless you don't really need to cool much. Also check the warranty (many are 5 years) and SAVE THE RECEIPT.

It's for our "weekend country house". It's a long rectangular room and I thought 1 on each end would be more efficient. Obviously if a 5000 is close in cost to a 6-6500 I'll go with the bigger option. All of the ones I've looked at have remotes and timers...not too concerned with the sound, but the ratings said they were all ~52db.

Because of the configuration of the room, 2 units will be more comfortable. Also, on those days that it's not too hot, one small unit will take out more moisture than a large unit. You should be able to run the 2 units in "quiet" mode which will give you the added benefit of removing even more moisture.

I have a 5 or 6K window unit for the bedroom during power outages. It has a remote and is much more quiet than the old widow units 20 years ago. I also have a 18,000 btu heat pump window unit in a rental I'm remodeling, that thing is noisy and getting replaced with a ductless system.

Go with 2 5k (or 6k) units, the reason is that you're taking warm air from two different places instead of a single area.

Mitsubishi mini-split system if 240V is available. You will never be sorry!
