What is the price for the 18k and 24k? The price is hidden for me as I'm not yet a member.

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.

How does it compared to the Aux 12000BTU one? It's $549 after 15% off coupon at Overstock.com: https://www.overstock.com/Home-Ga...:CartItems

The overstock one isn't a DIY one so you'll have to hire (most likely) an HVAC technician to put some refrigerant in the line.
