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

Quote from fafza :
Does the AC power need to be supplied to the condenser or the air handler?
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.

Quote from Tatersalad :
It'will be more efficient being on 220v. I always prefer the 220v versions. Same wire, breaker is more because it's a two pull. For some reason some people have an idea anything 220 costs more electricity, it's just the opposite you get the benefit of both phases…

Since I see several people giving bad info.

I'm headed to an event and will get into greater detail when I have time.

The 120v unit here is. 960w that works out to a max draw of about 8 amps while on high.

The same thing in 220v is also 960w divide that by 220v you get 4.36 amps nearly half at the same max setting.

So to help explain this… the 120v one will be drawing 8amps on a single phase which your electrical meter will show you taking 8 amps and your bill will reflect this.
The 220v one will be just a bit over 4.3 amps on both A&B phases, which your electrical meter sees this as 4.3 amps and your bill will be less.

The meters look at which ever phase is the highest and charges to that number, that's why balancing your panel load can save you money.
DO NOT LISTEN TO THIS ⬆️ GUY! He doesn't know what he's saying. Electrical meters monitor both phases LOL.🤦

This. I talked to an HVAC guy and they said it's typically from incorrect installation/tightening of the lines. The flared lines are apparently pretty delicate, so over tightening can cause leak, as well as under tightening
Sounds like the HVAC guy you talked to knows what he's talking about. Most people don't torque the fittings which leads to issues down the road. In order to use a typical torque wrench then you need crow's feet. Unfortunately the larger (suction side) probably requires something larger like a 21 or 22mm (which aren't included with most kits).

EXACTLY! You're billed for watt/hours not amps. And meters monitor both hot phases. If it's a 3 phase commercial building then they monitor all 3 phases. There's no free lunch with power delivery, I don't get why so many people in these threads seem to think so.

I didn't find vacuuming the units very difficult. You just need a vacuum pump kit, review some YouTube videos and be patient

Thanks for answering, will check it out
Don't be afraid to leave that vacuum pump on there for hours (the longer the better).

What is the advantage of 220 vs 110? Does it practically matter? I have a huge house and don't want to pay to condition 90% of it when I'm normally in my room. Is something like this good enough or should you pay more for a "name brand"?

Has more to do with how much power it draws. You won't see more than about 14K BTU on 120 volts. Higher BTUs push to 240 volts. Beyond that, I've got no clue. Supposedly 240 volt can be more efficient, but that isn't guaranteed. Check the SEER rating for the best.

Would you all recommend this vs the Yottahome 18000 btu 220v deal? I would be using it for a 620 sq ft garage.

Quote from AoDAzrael :
Yeah, but I'm willing to bet that when talkinng about an outlet most people are thinking of using a 15A. Should still be OK in MOST cases, but not if someone's got some crazy gaming PC setup and a mini beverage fridge on that same circuit.
Most 15A outlets are on 20A circuits due to multiple outlets sharing one breaker and 20A being the most allowed in that case. You are right if it is a 15A circuit then one unit will use up 2/3rd of the continues max load and then a crazy gaming PC could max it out. A fridge probably isn't that much of a load. My main kitchen fridge is only 130W when on. I would hope that a mini fridge would use less than half of that.

The yitahome and Costway are both made by the same company, Aux. The 12k from either should cover your needs. You don't want to oversize a unit either.

No 3 stage heat pump can operate below -5f - it's a basic law of thermodynamics. If 4 stage maybe. But that requires a electric condenser heater - which will cost a fortune to use.
Cut the BS and let someone informed talk.

Can these 110V units be plugged into a wall outlet or must they be hardwired? I'm looking for a heat pump that I can run from my Anker F3800 "portable" battery + solar panels in case of a power outage.
check the power draw, I assume it ideally runs on a dedicated circuit with 12 amps at least

Anyone has experience with costway vs pioneer vs tosot? I'm researching which of the three brands is better as they're about the same price and either made by gree or aux

which would you recommend?

I bought this it held for a few days then leaked coolant. After complaint for months they sent me another condenser I have yet to install
