That's not true anymore. There are newer pumps that will work down to -22 F. There are relatively cheap ones that will work to -13 F: https://www.amazon.com/Pioneer-Di...08K3N8QPS/ Even at -13F the heat pump is 2x as efficient as an electric baseboard. An additional source of emergency heat is still probably a good idea in any case, however.

It's very easy to do it yourself. I was able to do mine after watching a YouTube video.

Interesting. Nice chart, appreciate it!

Love that these mini-splits are getting cheaper AND more efficient. You use to never find 20+ SEER below $1000.
As JustinJ says, this is quite large for 350 sq.ft. An 8000 btu AC cools well an apt. I have that is about 350 sq.ft. Good price, OP, & repped.

R32 refrig is not available in the US, what happens if we need to recharge the unit ?
Just buy a new unit then it's probably cheaper than recharging it

How does "SEER2" compare to SEER? 21 SEER would be high, right?
Seer2 is harder for devices to hit higher number. It's a slightly tougher standard

R32 is considered to be the replacement for R410a. In fact, R410a is 50-50 of R32 and R125. R32 is actually available with licencesed. Restriction is due to flamability. You can try R410a as a top up for R32 for a small leak.
No, not exactly. Here's a link that explains everything: https://youtu.be/fpmCCmCFQLA?si=7YnoOR7GFjVnwkmu

Thumbs up to the OP for finding a mini split with a R410a replacement.

From what I'm reading manufacturers can no longer sell new R410a units in the USA starting Jan 1 2025 so expect some great clear out deals on r410a units

Warning: Only heats above 17 degrees F

I don't know why this wasn't listed in the text (it's shown in one of the images), but this kills it for me. Need heat well below 0 for it to make sense where I live.

Thank you for pointing it out will matter for some. That said most heat pumps won't operate below that and those that do usually use different refrigerants. They cost considerably more. My thought would be don't plan on using it as a primary heat source.

You won't find a heat pump able to heat you from "well below 0" to 70. That just won't happen. You will need another additional source of heat.

Important to make others aware, as that could have times when it won't function for me either. That being said, I have natural gas radiant heating already, but was planning on using this to reduce my gas usage overall. Plus the AC part is a huge bonus.

This good for a small backhouse about 350 sqft? Thanks!
Yes, mini splits are all variable speed so its ok if they are a bit oversized. They can run at 30%. That's why they have higher SEER2s then traditional heat pumps. Depending on amount of windows 6k or 9k is gonna be the required size but this one would work.

If you need to recharge the unit then you have a leak, which will cost more than the unit - so buy a new one. This is disposable pricing.
