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 baller11111 :
just switch the breaker and you have 110, most likely no need to run a new wire (check the gauge and run length with amps). Each model has the efficiency listed...that is what matters, not 110 vs 220
Not exactly how it works.

Does the AC power need to be supplied to the condenser or the air handler?

You should be able to put 2 of them on one 20 amp circuit and still be below the 80% max for continues use applications. With one on a 20 amp circuit you still got 1440W to be used which is enough for most other things.
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.

I already have 220 pulled for an existing 10 year old Daikan. I'm capable of taking the circuit down to 110 (and arguably could use another free slot in my panel as i'm close to maxing out). The 220 version is $50 more. Any advantages to staying with 220?
Keep in mind that if you plan on running your house on a smaller generator that is not 220/240 capable, you will not be able to run this AC. If you are on a 115, you can likely squeeze this AC load at least when needed.

For those that intend to put just use a plug instead of hardwired, you can probably put it in eco mode and it will stay well below 500W. Not legal but it's hard times right now so you do you.

Heck, a window unit or portable can pull 1,200W so I wouldn't worry too much.

If Houston gets below 5° you probably won't have electricity 😉
All these hypotheticals are kind of ironic; I equate it to someone who refuses to invest money with blue chip companies in the stock market. If those companies drop to zero and you lose all your money, there are MUCH bigger problems than your 401k.

If its below 5 in houston its probably a nuclear winter

How hard is it to vacuum the lines? I've installed a BlueRidge DIY system (similar to MRCOOL) myself and it was fairly easy. My utility is offering impressive rebates and I was about to buy a crap ton more of the DIY units but these ones are tempting too.

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

From what I understand, 220 units are generally more power efficient than 110

Unless it's a condensor failure, which if yours runs and needs "topping off" its likely not a condensor failure, the small leaks are at the connections from freeze/thaw. Re-flare the copper tubing ends and get new fittings. $20 if you're a plumber with tools, $300 to hire someone.

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

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?

Fwiw, i I have a pioneer unit that crapped out after a year or so. On the up side, as long as your unit is registered, you get 5yrs warranty I believe. Warranty process was cake -- they just shipped out the parts prettyuch with no fuss. You're responsible for procuring your own install labor though

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.
"No 3 stage heat pump can operate below -5f - it's a basic law of thermodynamics."
Sorry, but that's simply not true. There's no such law of thermodynamics, and there are heat pumps that can operate well below that.
It's simply a matter of matching the refrigerant used to the temperature range desired.
There are multiple "cold climate" heat pumps that have been developed in recent years that work well below that temperature. Mitsubishi has the Hyper Heat line, Pioneer has Hyperformance, etc., they all still work below -20 degrees f (getting less efficient as it gets colder, but they both heat well at -5 and can operate down at -22.)
But those high-performance high-efficiency models are a lot more expensive, and most of us don't need that kind of cold climate performance.

I just called costway and asked what model number this is and they told me fp10302us-wh
Searching fp10302us-wh takes me to a different model at costwav with a seer2 rating of 20.
The only reason I am considering ordering this for my travel trailer is for the Seer2 rating of 24, as that would run on 600 watts as opposed to 800 watts on the seer2 20 model. 600 watts would be pretty easy to run on 2 solar panels and still charge batteries at the same time, where 800 watts would probably need 3 panels

Now I don't know if it is worth it to sell my uninstalled pioneer 12k 19Seer2 model and buy this one or not

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.
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.
