DIY heh, go Mr. Cool, they come with precharged lines, as that brand is for DIYers. Course having the correct size ductwork is very important also. Your carrying the manufacturers warranty also.

May want to break open the box and check refrigerant charge and to make sure you don’t get a scratch and dent system ( from transportation ) from wherever your purchasing equipment as it’s on you once you sign for it, if things don’t work as planned.

 

i should mention, i am an exceptionally talented, experienced, and smart diy with lots of quality hvac tools (having done a few installs over the years) including nitrogen tank, vac pump, nice guages, etc. the only thing i don't have is a recovery tank and scale. I also don't really want to braze but i have sweated up a number of homes back in the day. i am looking at mr cool but leaning towards a mitsu or bosch inverter unit

 

Your buying the equipment then who’s installing it?

 

there is a homeless, mentally ill person wandering the area, i was going to have him install it.

 

Hey your stereotyping, not everyone who is homeless is mentally ill, may just be careful to count your tools afterwards.

Sorry that last part may be stereotyping…

 

I think Mr. Cool and Gree Flexx are the exact same thing except the Mr Cool has precharged line sets and quick connect fittings and Gree is flare fittings. (Gree marketed to contractors and Mr Cool marketed for DIY).

Mitsubishi would likely be the highest quality but not sure what is available direct to consumer, it may just be a rebranded something else that Mitsubishi slaps a sticker on and sells over the internet?

Fujitsu is good as well but like the mitsu, I don’t know what you’ll actually get through an internet purchase.

I’ve never seen a midea in person but I believe that’s who makes the Bosch inverter if I remember correctly.

Mr. Cool would probably be the easiest to DIY, as far as quality I have no idea but I doubt it’s great quality.

 

I rest my case!
