// About The (Not So Tiny) Tiny House Build Series //
I’m building a 630 ft2 tiny house / guest house in our backyard and covering the whole process, start to finish.
In Part 12, I covered my tips & tricks on lap siding installation, including the tools you’ll need, how to use a Gecko gauge & add a starter strip. Watch here : https://youtu.be/0QnPvJzJvpM
Part 14, which will be published on April 25, will cover installing the composite decking on the tiny deck on this tiny house. Make sure to subscribe so you don’t miss the upcoming videos!

Sir,, anu po ma isusuggest nyo na set up – 2nd floor to 4th rooftop bahay namin and mahina na ang water supply sa 2nd flr. Pataas,, oki lng ba sa rooftop ilagay mga pump and storage tank?
You didn’t do the electrical that’s not DIY
What type of amp 20 amp?? What about the electrical box outside is it 220 amp or 240??
I'm actually fairly sure you open the refrigerant valve first THEN check for leaks (I noticed you added sound deadening before opening the valve too). Either way, great video!
i have 3 bedrooms upstairs. Can I run linesets through the attic?
You may have oversized the indoor units the system may short cycle and to get the moisture out of the air.
No pressure test to see if the system is sealed and No vacuum on the system before releasing refrigerant? The Condenser comes pre-charged, Not the line set. I’m interested to know how this system works without being under vacuum because it’s the vacuum that helps the refrigerant boil at lower temperatures to create the cooling effect. Maybe I missed something but I’ve never installed Any AC system, whether it’s been a Residential, Commercial, Industrial or Military application without pulling a vacuum under 500/250 microns. A vacuum pump is $130 at harbor freight and decent set of gauges with a 4 valve manifold are a little above $250 with hoses. Worth every Penny and in most cases pay for themselves in the first decent sized install.
How much is the heating bill? We’re in north Alabama I might install one of these in a 1500 sq ft ranch
This is great, thanks. one thing, is there any point in 'checking for leaks' before charging the lines? i mean, if you haven't opened up the valves on the unit, then there is no pressure in the lines to push bubbles out, right?
Honest question.
Why would you check for leaks, before you've put anything through the lines?
Like there's a vacuum in the pipes before you open them, so you're not going to see any bubbling if there was a leak.
Unrelated to the mini splits – I'm in EU and most houses have concrete foundations, but thinking of building a summer house like the one you have. I've noticed it's raised on concrete slabs, and that you can crawl under the house.
My question is how do you deal with rodents/animals/ snakes and bugs nesting under the house, and if it snows there (or rains heavily) won't the bottom mold (since it's wood)?
Thanks in advance.
…..half way through, still no installation of the mini split?????
Curious – what was your longest run? Are they all 25 feet or did you have to use extensions?
You did one heck of a job explaining everything. I believe I can now install my unit. Ty sir.
Some obvious things on this video. Sawing thru those floor jousts was a huge no no. That would never pass inspection. Also oversized mini splits wreck the compressor as it has to cycle on and off too much. Mrcool only has 9k as the lowest size. In that small space you would need a 6k probably for a bedroom. I wonder if whoever lives in this is having problems with it
What size is the outside unit?
