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

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.
Thanks for the feedback. Any reason why I should go with this one over the Yitahome 12000 that's $417?

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
It's thin copper really super lame there's no simpler way to do this but it is pretty simple. Just seems stupid in this day and age for something so simple it's not just here's fool proof. But a lot of that is to blame on the eco green refridgerants... old stuff lasted forever because they ran on 30 psi not hundreds psi, now throw in hundreds psi with cheap mass manufacturing.....install it 100% perfect you're still a dice roll on not sprining a leak in the system at some point anyhow.

i don't even trust the torque wrench myself on the 1/4 line. I snug it, then snug it a bit more just by feel (not a pro btw). I confirm with a micron gauge and bubble leak stuff.

here's the deal on this DIY as with these i buy em cheap and if it dies it dies. If i screw up the install i'm out a few hundred.

You're spending sub or 500 dollars on these. You DIY it, let's say you don't do pressure test. You screw up the flare loose your charge,etc what are you gonna too? call in a tech for > 1/2 cost of the unit? go out and buy couple hundred bucks of 410a(? not sure what these use didn't look). No i'm gonna buy another unit and chalk it up and hope i don't make the same mistake.

.... Let's say you do the full 9's , micron, pressure test,etc all is well. We're still talking high psi refrigerant in a cheap unit, it is what it is. May not leak now will it eventually? maybe who knows it's the green refrigerant pressures that are the pita part.

...let's say you get the flared right (fairly easy), micron, pressure test all good and due to pressures something breaks in 9 months are you gonna hassle with the company for months and diagnose leak detectors dye,etc whatever where the leak could be? no you're gonna toss it.

So that's your risk. You see alot of talk on the nitrogen, when i did my first one i over tightened the 1/4 line, micron test good, cracked open high pressure line boom blew off line at the flare. Why? Because by over tightening you're cutting the flare at the base with the nut.
did it again blew off the other end! That's when i said ok my torque wrench sucks, it's a weeny line doesn't take much so i just did it by feel. Micron again, release and immediately check with bubble stuff. it's really hard to over tighten the 1/2 inch or whatever flare you gotta really be going nuts on it.

Now that first unit it was 26 foot lineset so did loose some refridgerant,oil but i had shortened the lineset to like 4 feet so unit still works fine. Personally at price of these cheaper units, learn to flare with simple tool, understand NOT to over tighten just hand tighten snug with wrench, then 1/4 turn. Micron test. *crack* open high line, and quickly bubble test. All good let it rip.

Anyways buy em cheap, let em rip. Be willing to loose a few bucks. If you're only going to do 1, hire a pro just not worth it. Want to do many of em? diy it, a few short deaths or one screw up is still massive savings.

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.

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 can't see any reason unless you want to pay more for this one :-). But maybe I'm biased because that's the same choice I made. They're literally the same in my opinion. Zoom in on the pictures, look at the remote controls, look at the grill, look at the screw placement, they both use the same app.

How diy friendly is this with no knowledge of HVAC or electrical at all?
highly doable but you will need the hvac guy for the refrigerant. mainly create a concrete foundation for the condenser outside, drill a hole throught he wall, mount the unit inside, run the power line into your circuit breaker. you do need to get the right gauge beause it's high current.

Quote from xllbenllx :
From what I understand, 220 units are generally more power efficient than 110
for practical purposes it's really more about circuit capacity, 220v less voltage drop, can run longer distances on thinner gauge wire, and that over 12000 btu you'll exceed capacity of a 15-20 amp circuit (or 80% of it anyways) and need to use 220v anyhow (not that there would be a choicec). For these either or, it's whatever is practical for you, if however you were gonna ruun a new circuit a long distance, 220v would be better as you would need less gauge $$ wire, and could run it farther.

What's "high" current? It's able to run on a 14/2 on a 15a breaker with about 8amps of draw max. If you are a considerable distance from your panel you should upgrade to a 12/2 to help with possible voltage drop.

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).

Look at the flares from the factory they are not always great. You can get a concentric flare tool that will made very good flares. You can also use nylok blue on your flare fittings to have a better seal. I have always re-flared everyone that I have put in mostly because I adjust the line set to fit the install.

That's 17 SEER2 vs. 24 for this one. Very different.

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.

Yes. Electrician is here. Just make sure you have a ground in the receptacle.

Quote from Esente :
> 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 ordered the yita home then instantly canceled it. I should've read the reviews before hand. It sounds like any real customer service is non existent. I had a friend order a costway last year. Their customer service was great. I messed up and released the freon before I vacuumed the system . So I basically vacuumed out all the freon. His unit came with a little dent.shiplign companies fault in sure. But we claimed it was damaged and leaked. They sent him a new unit. He also received it after he ordered in about 3 days. They're super fast.

Quote from juddev :
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
This model number and specs mismatch is what's concerning to me.
The brochure on their site shows models FP10293US, FP10302US, FP10318US, FP10324US which a 17 to 20 SEER2 and not 24 as claimed on the site.
I found the same items on Amazon https://www.amazon.com/COSTWAY-Co...2W3TD?th=1 and one of the customer reviews shows the box with a model number of FP10788US (which is sold under different brands) but even that model shows a max of 22SEER.
