I'm looking to buy one of these to replace a defunct mini split in detached garage. Current line set is ~16'. Can I leave excess from this 25' lineset coiled up adjacent to unit without having any problems?

It's a decent deal, but if you want an even better deal you can buy the 18k with a scratched/dented condenser for $1050 on iwae.com Just search "mrcool diy s&d" for a full list.
Have you bought from them?

Thinking about buying a unit and hiring an electrician do the 220v / AC disconnect. The work seems simple but I want to keep everything electrical up to code. Anyone else doing a 'half DIY' like this?

18,000 BTU/hr (this unit) is equal to 1.5 refrigeration ton.

Coil up the excess but have the coils laying flat, that will preclude the trapping of any oil.

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.

DIY installed one of these three years ago today, likely an earlier generation by the comments but same concept and company. Easy install other than the new circuit and disconnect, but I was more than capable to do that also - to code. At 3 years of constant running the fan motor is wearing out and will need replacement shortly. Other than that has been working great. Very good for heat in NC winters.

I'd also recommend looking into Sensibo smart controllers for these. Much better than the McCool app.

Check your local utility too for rebates.

Also check Pioneer mini splits - in February their 18K BTU mini split was $1200. Does need a vacuum pump but not difficult at all to set up vs the mr cool lines. Have put in several Pioneers and they're good quality and their warranty service (bad board on the indoor head) was good. Had to pay shipping for the part, but didn't have to pay for the part.

Does this mean that each split unit requires its own condenser? Is there anyway to connect multiple split units to a single condenser? I was hoping to have each of my bedrooms cooled off of one condenser.

No, this is a single zone. Multi zone units are much more expensive. I had the same question before.

Basically, 1 ton equals 12,000 BTU.

I need air conditioning in three rooms downstairs. Should I get a multi zone unit or get 3 of these?

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.
12000BTU= 1ton of cooling
