EG4 is a good unit. I ordered one but had to cancel because at the time I was buying it didn’t qualify for the tax credit. So I figured next best thing was Mr. Cool being they are made by the same company as the EG4. Also it’s been so long ago, but I don’t think EG4 would warranty a diy install were as Mr. Cool does. That might have changed though. Bed bath and beyond usually has 20% off on Mr. Cool. But I feel like you will be very pleased with the EG4.I just bought an EG4 9K unit today. Went with the DYI option with the pre-charged lines. I was hemming and hawing about getting a cheaper unit off of Amazon and just pulling the vacuum myself but what really drew me was how efficient this unit is with the SEER2 of 29.5 and the HSPF2 of 10.7 so for the price it's cheaper than a comparable Mr. Cool unit but a lot more efficient and of course the 30% federal tax rebate takes the edge off of the more expensive unit.
Maintenance and regular cleaning is going to be interesting with the indoor unit as I also have a wood stove for winter so the indoor air isn't the most particulate free. I use an infrared heater right now when I'm not using the wood stove which pulls 1.5Kw on high and 700 watts on low but that heater is only 5000 BTU so I expect this unit to use a lot less.
