You may need to hire an electrician for an extra 220v line. The DIY kit avoids having to hire an HVAC technician, or allows you to hook it up without vacuuming the lines.

I've been watching this in my cart for awhile, and it dropped nearly $200. Possibly an off-season / fall sale to get some inventory flowing.

According the CCC, it's the lowest price ever. The next lowest price being $1593.

One important thing to note about these DIY units is the Seasonal Energy Efficiency Ratio (SEER) is usually quite a bit lower than non-DIY ones. This one is 16 whereas a comparable non DIY unit is usually 20 to 24.

I live in soCal so would be using this for A/C a good part of the year so a higher SEER unit will probably be a better option in the end, even if I have to pay $$ to have it installed.
I purchased one of these from Costco a couple years ago and installed it myself. I think the main thing that makes it DIY is that linesets are already pre-charged with refrigerant so you don't need to call someone out to fill it. If you're competent with electrical, the rest of the install is fairly easy. Drill a 4" hole to exterior, hand up wall unit, run the linsets outside to the outside unit, hook up linsets and power to outside unit and you're done.
The line set is vacuumed and sealed at the factory. When you hook up the lines and open the valve it pierces a hole. Normally you would need to pull a vacuum to get any contaminates out of the system.

How difficult is it to DIY? I imagine its drilling a hole(s), mounting the units, and then plug and play?

What would the DIY kit include that a regular unit wouldn't?

in 4 one, been watching for a while. I have the power already, and should save lots in installation costs...
Shipping was free to the store and free to home on accessories (ship to home was $55 for the unit itself)

I'm hiring an electrician. If you're handy the rest doesn't look bad. Use the roof soffets if you don't want a new hole in your wall.

When we lived in Japan, I watched as a technician replaced one of these in our house, and it was really easy. He fed some wires/tubes through the hole in the wall (reinforced concrete structure), mounted the inside unit, and hooked everything up outside. Since there's no worrying about the refrigerant with this unit, the only difficult thing is the 220v line, and I know people who say that running one of those isn't as hard as others make it seem. Personally, I'd have an electrician run one of those though.

I spoke to a factory rep at a local event last week that had a booth setup for these units. This is pretty much what he said. The line set is vacuumed and sealed at the factory, so no need to have a HVAC tech pull a vacuum.

After you have 220 pulled to a disconnect at the outside unit location you can either set the outside unit on a (concrete) pad or hang it up off the ground (which is nice if you plan on using the heat pump in a location that gets some snow). The part to pay close attention to is the compression connections you need to make at the inside head unit and the outside unit. These are where you could have a refrigerant leak if they are not tight (they have some specific torque requirements). Something that can really help to ensure a leak-free connection is to use Nylog sealant on the threads of each connection.

Just installed this exact unit. Purchased from Menards (direct from MRCool). Easy to put in. Must be home for the shipping company to deliver. It's cooling my open floor plan 2000 sq ft area. Doing well so far.
