R32 isn't being phased out. It's also significantly cheaper then 454b which is what many manufacturers have switched to over 410a which is phased out.

You dont need an hvac tech to install these. Just order yourself a vacuum pump and gauge.

You can make the argument that all refrigerants with a GWP higher than 0 (or 1 or 3) are going to be phased out which would include 454b. This is a low cost mini-split. Not something you are going to be buying literally tons of refrigerant for in 25 years. Saying you shouldn't buy this and instead should buy something based on an older or a vastly more expensive refrigerant I would argue is fear mongering. If a claimed phase out is a concern than buy 20lbs of r32 and this mini split for less than 20lbs of 454b and you can recharge it every year.

I'm always 50/50 on these. I'd really like to replace the window A/C i use in my home office for a few months out of the year with one of these, and the heat pump feature is an added bonus. But i also need an electrician to do a bunch of work to do it right, and then it seems silly to cheap out at the end of all of that on the unit itself. At the same time it isn't a big enough issue for me to want to drop the couple of grand to do everything right.

Does this need a 220 line? How hard is it to install in a manufactured home?

220...221...whatever it takes.

The voltage is in the title.

And no, I'd suggest that you don't try that. Leaking refrigerant in your house is toxic and a homeowner wiring electrical to it is also not the best.

I haven't seen the specific instructions for this one, but generally it has to be tied to a junction box outside with romex or a new 110/120v line needs to be done from the breaker box.

Then a vacuum pump may need to be rented for 24 hours to remove air from the lines and whatnot. Air and refrigerant don't get along and even a little bit could damage the compressor and that wouldn't take long.

Then in 2-3 years the refrigerant leaks out because refrigerant lines are subject to persistent vibrations, and are usually metal hardline connected and that may mean welding/soldering. These are flexilines without the best end connectors. Easy for a handyman to screw up, and even if applied with the wrong torque could accelerate that refrigerant loss. If you keep recharging it every year because it's leaked, that's expensive and requires the vacuum be drawn down again. Two service trips, one to get the vac pump started and the other to come back, disconnect the pump and fill the compressor lines.

Then it'll quite likely die completely in < 5 years.

It's benefits are its cheap, more efficient than old portable a/cs, and its quieter inside than a window unit. It *can* be installed by a contractor or well experienced homeowner/handyman with knowledge of outdoor wiring and refrigerant related work.

That's some bad advice there. Any sort of inspector with half a brain is going to want to see a dedicated circuit and a disconnect on the outside. Plus GFCI? That would cause a lot of nuisance tripping. 🤷
They've also never seen a lightning strike on an outdoor unit, and how that turns out when it's plugged into a gfci outlet with a plug attached to the romex.

Lots of fire and magic smoke, perhaps even inside of the house.

I mean it says right in the description minimum circuit amperage is 17. You can't just guess its peak amperage on BTU alone.
I said "seer 17", seer is the efficiency, not the amperage. Cheap units have been 19-20 seer for a while now. If you do want me to guess the amperage under full load, i'd say about 11amps.

You can run them off a standard outlet but you will need to put a cord cap on the end of the power cord.
I really need a tutorial how to connect the indoor unit to plug to an existing power outlet

Is it worth it to get this for heating only? Looking for heating options for the basement.

Please be aware this uses "Refrigerant: R32" which is more expensive and is being phased out. Also, the SEER (17) is a little low for my taste. I usually like to be 20 and above but that cost more usually.
they're phasing out our 410A in 2025. every condensing units coming with R32 in it

our 410A is being phased out every AC unit or heat pump is coming with our 32 in it. so what are you talking about?? 410A cost more than R32 right now...

410 Is being phased out starting in 2025. all the new units out there being sold right now have R32 in them so dude's insane. heads up everybody don't buy anything with 410A!!!! But be buying pallets of 410A refrigerant. if you've got the EPA license, you'll be able to flip those cylinders over the next couple of years

holy Christmas! we've got a real connoisseur here. listen. this is close to one ton... And anything above 20 seer is a total rip-off. considering return on investment, I'm running 8 tons worth of variable DC scrolled condensing units and I've got a program that calculates the return on investments. you never want to go above r20 and r17 is perfectly fine because most people that don't get informed get stuck with it. a 14 seer when someone comes and does a chop and swap and rips them off with a good men unit. you got to be careful. someone doesn't sell you a 14 sear Goodman 410A unit. the refrigerant's going to go through the roof starting next year. This is a freaking steal. it's nearly a 1-ton heat pump running R32 for $460. If you had a 1600 square foot house, you could buy three of these units in heat and cool it for less than $2,000 and zone it. 20. sier seer and above is a rip-off on your return on investment. $17 to 20 is perfectly fine because most of those units are variable speed condensing units. anyways, my two 4-ton units start out at 30% and work their way up via DC drive and 1% increments

A vacuum pump is a couple hundred and a good digital Gage that's going to cost you 500 bucks even if you get an analog one. the yellow jacket hoses are going to cost you $150. some of the Mr. Cool units come preset up so you don't have to pull a vacuum. you just screw them in and you go. I don't know about this unit. I've never heard of this brand but I would personally stay with Mr. Cool
