It is cheaper, but a lot lower SEER rating of only 17.Damn the 230v is even cheaper, so tempting. ?

The Gree is twice as much, and usually has a lower efficiency. What's the deal?Wow, the Gree is over twice as much as I paid for the pioneer. I really hope it’s not “you get what you pay for”..
Luddite … that’s funny…?I got my dad the 18000BTU MRCOOL DIY for his 2S2P garage (2 cars wide, 2 deep) so he and my brother could install it themselves. The only thing they didn't do was the electrical work. They weren't comfortable with it.
He's thrilled with it. His only complaint is that the 4' CFL fixture near the unit interferes with the remote.
EDIT: And he's too much of a self-admitted Luddite to bother with setting up the wifi access...![]()
He's a HVAC guy. His opinion is likely worthless. These guys gatekeep haaaaaaaard. And I say that as a guy that bought Mitsubishi. They rank slightly below ambulance chasing lawyers in my opinion and vote party line. Most of them anyway.Found this site from another thread, posting the following article because I think it's relevant here. I hope his opinion about pioneer being ewwww is grossly incorrect.

Mitsubishi vs Fujitsu vs Daikin vs Gree
We compare Mitsubishi vs Fujitsu vs Daikin vs Gree in this 4-way shootout between four of the most popular ductless mini split heat pump systems in Phoenixairconditioningarizona.com
The dedicated crowsfoot is the only thing that I didn't buy. I did however, buy a Icon flex torque wrench (useful in other applications) and already had crows foot sockets. Some math is required with doing it this way; I'm no @Hedges, but it's pretty straightforward.as for torquing the line sets, I didn’t buy the crows foot stuff cuz I’m ”Cheap” so I simply tightened them up. The bigger line I tightened up harder. I was careful not to overtighten the 1/4” line to not crack the flare. Vacuum held for 1.5hrs so I suspect no leak. Also used soapy water after cracking lines open and shutting them, then again with soapy water after fully releasing refrigerant
Sweet. Got to love it when shipping is early.Wow! The mini split is coming via FedEx in 2x boxes, like usual. Amazon estimated it would be here between the 19th-22nd. I was really hoping for the 19th because I could work on it over the weekend. But I checked tracking on FedEx website and its out for delivery today the 16th!
Can't beat it!
Error, wrong post somehow, why is there no delete?I have Mitsubishi Mr. Slim's in the house, and they have one characteristic that I cannot stand which might be relevant to you: the coil temperature is too low so they do a lot of latent cooling. (Aside from the bedrooms, my house is naturally ventilated. There are no vapor barriers between the conditioned and unconditioned spaces.)
The problem I have is that sometimes I just need a lower dry bulb temperature, and there is no need to dehumidify. Many garages have significant air leaks by commission or omission, so when it is humid you will use a lot more energy than the equipment will ever benefit from.
Controls on these mini-splits leave a lot to be desired, and there really isn't a way around them.
The tiny piece of advice I will offer is that you are better off installing 2 1-ton units rather than 1 2-ton unit if you need to run the mini-splits when their loads are going to be fairly low-- just shut off one of the two units and let the inverter have maximum turn-down on the other.
Lt Dan is in Tulare CA, it’s pretty common to have heat near or over 100f daily for the summer in the central valley. It’s typically “a dry heat” in the central valley, but blazing sun May into October.I have R40 in the garage ceiling, insulated the door panels ( $300 kit at lowes ) and have had zero issues on maintaining temperatures. I don't know "your" people, but most just throw out "be safe" numbers.
My previous home I had installed a 3 ton heat pump for a 2600 sf home, again, just had good insulation in the attic.
If you keep the sources requiring BTU's at bay, it doesn't take much to maintain a temperature. An example is a walk in freezer, they have very small units, like the size of a window AC, but they have all sides, top and door insulated.
That is the exact one I bought.Of course I find this now... $555 with a $55 coupon

Hey! We HVAC guys aren't ALL chasing the dollar!He's a HVAC guy. His opinion is likely worthless. These guys gatekeep haaaaaaaard. And I say that as a guy that bought Mitsubishi. They rank slightly below ambulance chasing lawyers in my opinion and vote party line. Most of them anyway.
He also cherry picked the models of the ones presented making the outcome be what he wanted it to be. Must be more markup on on Gree.
I've seen this argued both ways. You being an actual HVAC guy, can you elaborate why?Testing how long it'll hold vacuum is meaningless.
Why is that meaningless? If it doesn’t hold vacuum there’s a leak. Also after fully releasing the refrigerant and putting it in heat mode the psi is up around 500. That’s when I soapy water tested it. Doing the vacuum for 30min and then letting it hold for 30min and using soapy water in heat mode is the pioneer manuals recommended procedure.Testing how long it'll hold vacuum is meaningless.
