Based on the specs, it will pull 9 amps. These things sip electricity.

Could you terminate to a plug? Yes. Should you? Probably not. Feels like that would not meet code, but I can't confirm that. Just sounds suspect.

That said, I have a Costway 18K BTU mini split in my 1,000 sqft shop with very little insulation. It works well, but it isn't but enough for the shop. I knew that putting it in. I paid $589 about a year ago, but no WiFi on mine. 220 volt

I installed it, and consider myself slightly above novice. I know enough to be dangerous. Plenty of online videos. Only odd tool you need is an HVAC vacuum. Otherwise all the tools you need you probably already have.

Instructions are detailed good. The only issue I had was really around the electrical wiring . The wire colors on the unit did not match the instructions, so it took me a bit to figure it out.

You are charged for the *power* (watts) you use, not the amps..

--

Power = Current x Voltage

110v x 10 amps = 1100 watts.

220v x 5 amps = 1100 watts.

Don't trust the specifications, such as heat range, from these marketers. Trust what the other poster said about the law of thermodynamics and heat pumps. These two units you are considering are highly likely exactly the same and both made by AUX. You will see some marketers claiming a different sear rating as well. I just finished up installing my yitahome a few weeks ago. Here is a video. https://youtu.be/hYYoWePYU1A?si=Nbe9jorsslMQEHOA

Just went through this thread, found several posts with incorrect info and advice that, if followed, could prove disastrous, even deadly. So many clueless who want to believe they know, why?

But many with good info too. If researching to learn (and can't tell the difference), please check legitimate (such as trade) sites.

Why don't you educate us on what is correct?

Quote from Tatersalad :
Commercial have demand meters, completely different way that they work…We have a family business that has operated for over 80 years as a electrical contractor. I've been around it my whole life. In residential the meter monitors both phases correct but whichever one is the highest is what your getting charged for. Hence why some people with unbalanced loads in there 2 phase panels have high bills.
I worked for a utility company for over 40 years, and that's not how it works. The rate schedule for the commercial/industrial bill has a "demand" component in addition to the power use component. The residential rate doesn't have the specific separate demand charge. When you say the residential meter charges you for which ever leg is "higher", you are incorrect. It measures power "Kwh" kilowatt hours. That is the usage component you are charged for.

Quote from TheMentalNomad :
You connect power to the outdoor unit. (Here in NJ, there must be also be a quick disconnect accessible near the outdoor unit.)The bundle of cables and hoses running from the outdoor unit to the indoor unit will provide power to the indoor unit, so no special wiring needed for the indoor end.Better to call these "outdoor" and "indoor." When it's in heating mode, the indoors unit is doing the condensing. When it's cooling, the outdoors unit does the condensing. It's a reversible air conditioner.
Agree with most of this, but the indoor unit is not "doing the condensing" in heat mode. The more precise term is "air handler" and it diffuses the heat or coolness sent to it by the condenser into the indoor air. That heat or coolness is transported by the refrigerant fluid, and that fluid is heated or cooled by the condenser which is outside.

To be even more precise, you're charged for energy (kilowatt hours, kWh) not power (watts or kilowatts, W or kW). Some businesses might have a 'capacity charge' that corresponds to their peak power draw, but that won't be a concern for almost all residential customers.
Your core point is right, though - there's no meaningful difference between the energy consumption of a 220v or 110v unit.

Thank you all for this thread!
One of the funniest i've read in quite some time.
It's as if The Three Stooges opened a DIY Electrical and Air Conditioning Company.
Much like their foray into Plumbing, Moving as well as home remodeling.
What could possibly go wrong...

I have a garage gym. I want to install this in my garage. Will it work well? Is it safe to install one of these in a garage? Can I extend an existing 110v outlet and plug it into that? The garage walls and the attic above is not insulated. My garage door isn't sealed that well either. It's a single garage

If you cant install this yourself, get a quote first, installation can be quite high for these units (well over the price of the unit)

> heat even at -15℉ and cool even at 126℉

This is amazing. I'm debating between this higher-priced one versus the Yitahome in the other thread. The Yitahome can only do 5°F to 118°F. But.. the temperature has not gone lower than that here in Houston. Decision, decision...

I bought the 24000 BTU YitaHome and installed it this weekend. Works good so far!

It will work, but not very efficiently since your walls are not insulated. Your breaker will most likely trip if you attach it to an existing circuit. HVAC's should always have a dedicated circuit.
