The listing says this will heat down to some very low temp. Anyone know if it's true? I install a basic $500 12000BTU unit 2 years ago but it stops heating a little below freezing. Wish it would heat at lower temps. Unsure if this unit would be the same or if it's an upgrade. Wonder if I should buy this as a spare and store it or wait for a real hyper-heat type unit slick deal.

Min op temp is -13F. The only worry is that there is a loss of efficiency when heat is turned on and temp outside are low. What is the lowest temp for your region?

No. Not really. Its free if you just follow si.ple youtube instructions. All units now a days come already pre filled with freon and already vacuumed. Just watch the video and you will be good

I'm in MA and -13f is as cold as it gets but I'm skeptical if it will make usable heat much below freezing. Maybe I should save up for a hyperheat type model even if it costs 4x as much. I'd like to stop using oil.

That might be the way to go. There are some reddit posts that talk about hyperheat. They cost more, but cheapest i saw is Della 12k btu for a grand. If you are doing diy, it might be worth it.

I generally agree but people should be aware they'll need a 230v breaker in their panel, and they'll also need a carbide tipped hole saw if they're going to be drilling through stucco and block. And my understanding is that yes it's precharged but they still recommend vacuuming the lines. Mine arrives today and I'll just get use Autozone's free loan program for the gauges and vacuum pump.
