This advice applies very well to conventional ac units that only have 1 speed, or the "new innovation (lol)" of having two whole speeds. But with mini split inverter technology they can run at virtually any variable speed. That's what makes them whisper quiet most of the time. You still don't want to go too big because they will get that swampy/musty smell in them from running too slow constantly, but they are definitely more forgiving than the huge central ac units that the industry refuses to admit is archaic. I converted my house over years ago from an 8 SEER unit from 1995 to multiple mini splits that all run at 19-22 SEER. Energy bill is a third what it used to be or less and I did not have to spend 8-15k dollars on a 13 SEER "modern" central unit that would have saved me far less per month. Was able to afford each unit with cash every few months and did not have to finance a thing. If one dies, it's a small relatively cheap fix and you upgrade to the newest technology. These are a win-win all around in my opinion.

1) Mini split systems can be oversized. It will not affect humidity removal like it does with standard on/off single stage compressor systems.

A 18,000 btu mini split I installed can perform a minimum of 5,400 BTU's.
I'm not saying install a 18k system where a 6K is needed, but installing a 18k system where you need 12K will not cause you to have high humidity.

2) 700sq feet per ton should not be used for everyone. Region and building design determine cooling and heading load. Parts of Michigan with great insulation may only need 1 ton per 1,000 sq ft. An area of Texas with bad insulation may need 1 ton per 300- 350 sq feet.

3) You must also factor in heating performance in your region and unit specifications. A 12,000 BTU cooling unit may get 16,000 BTU of heat at 47F, however it may drop to 8,000 BTU at 5F.

Bought the 24K, but wish they'd sell the 12K since I think 18K would be too much for a bedroom.

18K = $1,299.99
24K = $1,499.99

I'm looking to put one in a 660 square ft garage with 9.5ft ceiling. Would the 24k be overkill? I like the idea of the stronger unit to help bring the temp back to normal after a garage door is opened to bring a car in/out. What do you all think?

24k is overkill IMO, 18k is perfect and my garage is 550sqft with 8' ceilings and would love to get the 12k one...

About how long after you open a garage door does it take for the temp to go back?

It doesn't look like Costco ever carried the 12k version per my searches of past SD threads. Wish they did.

Same. Sam's club has it but OOS. I don't mind wiring 220v but I would just be fine with the 12k and 110v is just easier.

What about a 200sqrft barn style shed with 13ft tall ceilings. Will be insulated and located in northern Utah. From my research I landed on 12k for 200sqrft, but I'm not sure if that is taking into account the tall ceiling.

Depends, do you care about having the last 3-5 feet as cool as below? 13' is ~60% more height than standard 8' ceilings and I believe the 12k is fine for 500sqft @ 8' ceiling. So it should be totally fine for your barn.

Nice! 18k and 24k are both back in stock. I previously posted the other Costco MrCool deals and saw that they were still out earlier this afternoon. Wish they still have the 12k system available since it would help a lot of people out here with the ease of install since that system runs off of 115VAC.

Great thanks! Sounds like a 12k would work. I plan on using a mini split for heat in the winter as well. Is there any benefit to over sizing the system?

I don't think so. I mean except for having to wire a 220v circuit and that bigger units usually cost more. I don't see the issue. Perhaps bigger units can be louder too?

You don't want to oversize an AC system. Part of what cools a room is the heat being pumped from the inside to the outside, but the other part is the humidity being removed. If you get an oversized system it won't cycle on long enough to remove the humidity so you will end up putting the temperature lower than you really need just to get the system to turn on longer so it will remove the humidity. For a 1-story structure you can get 700 SqFt per 1 ton. I do not see the tonnage of these units so you may need to contact them to find out. The heating is measured in BTUs.
