Most AC companies do not want to install a mini split unit that you did not purchase from them. That was my experience at least. I reached out to 6-8 companies and only two responded. One straight up declined to do the job and the other wanted to charge me $90 just to come look at it. They did tell me over the phone that it would cost about $1000 to $1500. I would either install it yourself or find a company that's willing to do it before you purchase this AC unit. Just my two cents.

can you advise if it is loud?
I installed the 18k version. The indoor unit, even in the lowest fan speed is very loud. I'd say as loud as a big fan on medium. Its noticable. The outdoor unit is quiet.

Im comparing it to a gree unit at 9,000 btu where the indoor unit is silent.

Nothing complicated for a pro. It's just not their business model. They make money from installing new AC's, which is few grand per job.

I installed one myself, couldn't get the pressure to hold. Finally got someone to come out, and they quoted me $1,400 telling me it would take them 4 hours to fix. Long story short, bought some refrigerant online, fixed a kink and got it to work myself (in probably less than 4h being a complete newbie).

Reposting from the last costway thread!
  • There is great discussion about heat pumps and DIY installation in the FAQ of the r/heatpumps community on reddit [reddit.com].
  • In most states, you do not need to be a licensed HVAC contractor to install one of these systems and can still do it "on the books" by pulling an Owner-Builder permit. For example in California: https://www.cslb.ca.gov/consumers...rview.aspx
  • R-410A is being phased out and R-32 is the primary replacement, so this system being on R-32 is not necessarily a bad thing. That said, most HVAC systems being sold in the US today are still R-410A so you might have some more challenges locating refrigerant and technicians willing to work with you. Generally, you need to have a dedicated set of tools for each refrigerant type.
  • All heat pump systems have a factory charge that corresponds to a certain line length. You only need to add more refrigerant if you have longer lines than what the factory charge is good for. I reviewed the documentation and was not able to find this information, but it should be printed on the label on the side of the unit.
  • This system is listed on neither the NEEP Air Source Heat Pump [neep.org] or AHRI Certification [ahridirectory.org] directory, meaning that its performance has not been validated by a third party source. This could mean that the efficiency is very poor, but it might be fine. However, Costway's website says that the unit has AHRI certification, so either they are lying or there is certification under whatever brand they are buying these units from and white labeling and they didn't bother resubmitting the certification under their own brand.
  • Here's the instruction manual if you don't have a Costway account yet: https://cdn1.costway.com/PDF/inst...-12WHA.pdf
  • If you live in a cold climate (below ~5F in the winter), you are going to want something that uses vapor injection technology [youtube.com]. Typically these systems are branded as "hyper heat" or "extreme heat" and work quite well in low temperatures.

Feel free to DM me if you have any heat pump questions, happy to help out!
I suppose I have a question, I'm a mechanical engineer living in a 1938 built duplex in San Diego. Renting. Think I could get away installing one of these? Or not worth risk since not builder/owner?

Kinda screwed bc attic and no central AC means my unit doesn't get below 85 degrees for 1-2 months a year. Windows open horizontally so I can't get a window AC. Portable AC means I have to section off my bedroom and spent $100+/mo to cool it to sleep. Ugh. Typically split AC in the $1,200 range or 230V, but for 120VAC and $500 I'd probably make the money back on electricity bill quickly

Waiting for same answer to this q
Idk, I researched the Mr Cool previously, and there were enough mixed reviews where I didn't accept a $1450 risk. However, I'll only be in my place for 3-4 years max so I'd need everything to go super smoothly to earn back $1450 in electrical savings. If I'd have had it for 10yrs or something I'd have been less concerned

I got this one from the earlier deal to replace a senville whose compressor started to sound very worrisome after 3 years.

Works fine, but feels a bit more cheap than senville.

Not compatible with Sensibo which is a bummer.

R32 refrigerant is pretty much impossible to get, so you have to get the install right the first time — I recommend investing in a torque wrench to correctly torque the flare nuts.

Been running this one for almost exactly one year now. Did the install myself, just bought the cheap vaccum pump and gauge set on amazon and everything went well enough. Did not cut back lineset or re-flare, and did not use sealant on the connection (I would now, but didn't know about it at the time) and it has remained functional. I am at the point now where after getting near continuous use, that I feel ive at least gotten my monies worth out of it, and hopefully work even a while longer.

A lot of nay sayers nearly had me convinced that it would fail after 2 months and that it was a waste of time and money, but I think if you are reasonably intelligent when installing it and treat it as a semi-disposable unit, you can also be happy with it.

Only complaint operating it is that the auto function is basically useless. It will remain cooling 100% of the time and I manually stop it when I realize the room is more than 10 degrees cooler than the setpoint. I think I expected it to cycle on and off to hold a temp like a central AC, but it just runs the fan at a slower speed... which happens to be enough to still over-cool the room.
Just fyi. Split units and even most ac units. If you close one of the sides. High or lower pressure side I forget. You can then run the system and all the freon will eventually go back into the system. Then you can close the other side. Trapping the freon back into the system. In case you decide you want to use sealant ont eh threads. Vacuum the system again if course. I also diy 3 systems. 2 of them I ran and drew the freon back in becuase I had to temporarily move it. Still ice cold.

If you don't vacuum the lines. Your system will prematurely fail. I know a lot of these diy systems say you don't need it. But any moisture will destroy your system. Also. When you tighten the flare nut. You have to have a wrench if both sides so you don't break the receiving end. You don't need to over tighten these either.

Your amperage dictate cost of electricity. 230v just draws less amp per phase to prevent over hearing of the wires.
