I have installed two of these dual inverter 14k BTU window airs in house #3. At the very least wife and I will not sweat to death at night. Office is still un-cooled.
Nipped over to the house with the shop and build a couple stands for them quick to avoid too much weight on those ancient window sashes:

What’s the deal with the “dual inverter” business? Just to make it sound fancy and high tech? Or actually does something beneficial over a
regular non-inverter AC unit?

Stolen from Quara:
A dual inverter air conditioner gets its name from the “twin rotary compressor” that it houses.
Normal inverter compressors used a variable speed, single-cylinder, single rotary compressor operating on a single-rotation, single-compression principle. This compressor structure, however, was short of assuring the air conditioner its full performance, because it is liable to vibration, noise, and shaft whirling associated with rotational imbalances, limiting the minimum and maximum working rpm.
On the other hand, a twin rotary compressor is furnished with two compression chambers to produce a phase difference of 180° in their mutual compression timing. With significantly improved rotational balancing and compression torques. the twin rotary compressor operates from as low as 720 RPM to as high as 9000 RPM.
It has not only brought about a five- to ten-fold increase in the variable working rpm range (maximum/minimum RPM), but has realized high efficiency, low noise, and low vibration throughout the RPM range.

I guess it’s sort of like a mini-split in a box tech wise. It’s supposed to be 25% more efficient, more quiet etc. It is VERY quiet compared to what I’m used to.

I cool my 24x32 garage with a tiny little 10 year old window unit with no sweat. A block/stone/brick house built in the 1900's with 11 foot ceilings main and upstairs needs a little more umph.

My garage is about the same size but i only have fans. :(
One day ill buy a house with central ac but for 800ish square feet main level its fine. Luckily basements naturally stay cool.

My AC died on our first 100 degree day last month when I stress tested it. I fixed it myself that week in the morning while everyone else slept . I live in Phoenix where you can die in your house in summer without AC. I am a golden god (AC units are actually stupid simple to figure out and fix if you have experience keeping old shitbox trucks and motorcycles running).

I have a 24000 btu 240v jobber in the kitchen, a 12000 btu in my bedroom and a 14000 btu in my kids room. Roughly the equivalent to a 4 ton, in a 1000ft2 apartment, in Canada . Can barely keep the place comfortable. Once it nears 30c it starts warming up and there’s just nothing I can do about it. Top floor, flat roof, tongue and groove ceiling with nothing but torch-on on the other side. No insulation to speak of. Fans help too, but p ower bills usually $300 a cycle in the summer months.
Bet ter than not having any at all though.

I can’t imagine not being able to read and understand a wiring diagram on something simple like this and use a meter to test and understand what might be wrong. Troubleshooting basic electronics and mechanical systems are Life skills imho. I hope I manage to teach my kids how to do it.

That is a serious amount of cooling. These two 14k btu units were the biggest dual inverter ones I could find that were still 115v. This house has newer wiring, including some “dedicated” circuits for AC so I felt ok running big ones units but no 240 runs for AC.

Lack of 240 was a bit of an issue here as well but the deal on the bigly ac was too good to pass up . Only outlet was for the stove and I couldn’t go modifying the buildings electrical system. I built a relay box that plugs into the wall and directs the power to either the stove or the A/C depending on my needs, actuated by a surface mount 120v light switch. Desper ate times and all.
If it’s that hot I’m probably bbqing anyway.

In this case I didn’t even have to look up a diagram. You basically just have a condenser, radiator, capacitor and fan. My fuses were good, so I jump started the fan and it ran. It’s been starting up by itself, so I think the motor just got rusty from sitting still over the winter and fall.

Thanks. I don’t think I understand the rotary compressor business. I was mainly curious about “dual inverter” thinking it was AC -> DC twice.

the inverter is so it can use variable frequency
DC to drive the compressor as needed. TIL.
