I jumped to the end and saw $2.3k for the mini split and couldn't believe it. I've installed mini splits on two homes and the quotes were always in the $15-25k range for 3-5 head units, so $2.3k for a head + outdoor condenser unit sounded implausible, but then I saw he found a surprisingly good deal: > I got a ton of quotes for installing a mini split.

Honestly, I would recommend just doing it yourself. Especially if you have a contractor pull in the electrical connection for it. I installed a pre-charged unit in a much more complicated attic setup (condenser mounted to outside wall on second floor, 20' of refrigerant lines run with lots of angles) and the whole thing took 6-8 hours with no experience. Mounting it to a shed where you're basically just cutting a hole in a wall and the indoor unit and outdoor unit are in more or less the same location should be extremely straight forward. The unit cost me less than $1k five years ago and has been running perfectly ever since.

one thing about discount DIY mini splits: they're sometimes/often the same model, with a hodge podge of similar but not identical components. it can be very difficult to get a repair person to work on these - they stand a lot to lose if they try to operate on it and make it worse. they really prefer consistency, and - they also seem to harbor a bit of a distaste for diy systems. Actually, I was educated by one serviceperson's opinion and by the end of their complaints, the experience cost more than the cash, injury wise. But I think relaying this, has some value, because I suspect it's common.

Thanks for taking the time to make this detailed write-up! You got a beautiful result, and I appreciate the spirit of sharing what you learned and helping people who are considering similar projects. I'm glad you measured CO2. I've recently noticed I tend to get headaches when working or sleeping in small poorly-ventilated spaces, and I'm surprised how often I encounter new structures without ventilation. I guess tig…

There isn't really any clinical evidence for CO2 levels impacting stuff beyond so called "sleep efficiency," where the effect is small (above 1000 ppm is 5% reduction in sleep efficiency) and it has the counterintuitive effect that less efficient sleep is sleeping longer, which is usually what people want. That said, placebo effects are still real.

Im jealous of the Tuff Shed or prebuilt being an option. Where I live we have incredibly high snow loads, so any structure ends up needing to be custom built to meet our requirements (even out buildings). I've found plenty of pre-fab units that claim to handle "high snow loads" that will not meet code where I am. I'm still planning on building out an office/studio, but it will be a much larger investment despite bein…

Cool app! I have plenty of building experience thankfully, including plenty of structures still standing under the weight of our snow load!

Boy things are different in Portland where you pay people to insult sheds… But 8x10 for $20,000 just goes to show how expensive USA is for construction. There’s a point where I would review coworking space cost (not as convenient, I know) to just living and owning property abroad.

In this day and age, where material stuff is so cheap, isn’t 20K for a tiny shed crazy? Clearly it is because it involves so much work, and work is so expensive, but I can’t help but think there should be a technical solution to this. Or buildings are just not automatable? I’m amazed.

You could do it for less than half that cost if you do your own labour. I actually came into the article thinking that’s what they did but was disappointed.

I bought my first minisplit ~4 years ago since none of the contractors were available in the hot summer. I bought the tools as well (vacuum pump, manifold, pipe cutters, etc.).

It cost me ~650$ total.

The next time I bought a minisplit (3.5kW one), I already had the tools and it cost me only 450$. A proper one meant for use during harsh winter would probably costs a bit more though, at around 1000$.

So I have set up a few of them for my family and friends so far. The units come pre-charged with gas for ~5M of ducts, there is nothing hard to set them up.

I also set up ESP32 controllers so I could attach them to Home Assistant, bypassing any Chinese cloud apps, etc.

Earlier quoted context omitted.

Heat tape isn't very effective with storms dropping multiple feet of wet snow in under 24 hours (or in general).

woof, where are you located, coastal/northern Canada?

Cascade mountains. I've seen over 5 feet of snow in under 48 hours, then freezing rain. Its heavy! Lots of these "it'll be fine" type structures collapsed.

Building code for snow load is a factor of location and elevation here. We are around 130 lb/sq ft.

Roof pitch can help with shedding, but then you've got other problems (roof avalanches can and do kill, not to mention snow up against materials that don't want to be wet all winter).
