Just got a quote for a mini-split install, 2 condenser units for a total of 6 indoor heads... $45k. :2monocle:

Yes, I have 2 more estimates lined up. Pretty wild.

Having trouble finding much about Tosot mini-splits. I know they're Gree, but anyone else have any details they can share? How do they stack up against Mitsubishi?

Also, how much weight do you put in labor warranty length? Gathering quotes and some are offering matching parts + labor warranty, and some are offering parts warranty, but only 1 year of labor warranty. Would you consider that a red flag?

I'm trying to figure out if I can install a radon fan where the pipe is exposed not in the attic, but two floors down. So roof, attic, then a floor, then a floor with the exposed pipe. It goes straight vertical. I know that static pressure is involved, but I have no idea how to calculate it and I can't find any rule of thumb guidelines for install instructions that cover it. I know that suction also plays a factor, but I believe we're good there and that head pressure is my main concern. I'm thinking about just trying to install a Rn 4EC-4, which let's me dial it in a bit, but figured I'd ask here first.

[Edit: our radon readings are borderline as it is and I'm just trying to be proactive about it, so I can't imagine it has to be perfect.]

Both good points. Hmm, guess I'm crawling around in the attic with blown insulation. :smith:

Yeah, I might as well just do it right. It's borderline, usually under 4, but when it snows and the temp drops to close to 0 it shoots up to around 8-10. My problem is I'm happy to pay someone to do things, but we're in the sticks so it's hard to find someone to do it. I think there's a Radon specialist who has been doing work out this way that people seem to like. Just not sure if he's the "crawl in the attic" type. Also I'd hate for someone to get all the way over there just to find out there's no outlet.

Thanks thread.

Maybe I could rent out my garage. It's heated and doesn't have the passive radon piping.

Mini-splits are magical. Get one.

Does the Mitsubishi qualify for more local/state/federal rebates? Might make up the difference.
