Next time have someone outside to let you know when the pilot bit on the drill breaks thru the concrete then go outside put the pilot bit in the hole and finish drilling. Done this for years and no concrete patching will be necessary. Looks way more professional.

If you can afford another $250 or so I would recommend getting a set of referigeration gauges and a vacuum pump (Harbor Freight). The referigerant line connections are the most common point of failure in DIY installs. Someone who does this all the time will be able to tell when the fittings are tight enough to seal just by feel. But for non-professionals, after everything is hooked up you can connect a set of guages and the vacuum pump, then draw the system down into a total vacuum. Close the valve to the vacuum pump and let the system set idle for 24 hours. If it's still in a complete vacuum you're good to open those valves and let the referigerant charge into your tubing. If not, you saved yourself a very expensive service call because you would have vented your referigerant charge into the atmosphere and needed to call someone to locate the leak and recharge the system.

A couple ideas: check studs before starting, you can make sure the inside unit will land on one and the hole will not. Also make your hole slope slightly towards the outside of the house in case of water.

Yes, counterboring from the outside should prevent the breakout problem. Another tip for various situations is that a holesaw ran in reverse doesn't grab. Its a good way to start holes or when dealing with materials that tend to grab. A shop vac or the suction end of a leaf blower is good for dust control.

I would say instead of leveling the outside unit on the dirt you should have laid a layer of gravel, compact it, then lay loose gravel to level the platform on. That way it will remain level for years and will have good drainage around the unit

Did one of these a couple of years ago. Easy to install and still working great. We bought a wall mount so it didn't sit on the ground. Ours also has a wifi connection so we can control it from anywhere via a phone app.

I worked as technician for installing these ac i really recommend to put your tube under pressure with vacuum pump and check for leaks then vacuum the tubes and turn the gas on that way you can be sure to not lose any gas it's good for environment and your pocket 😉

If you do one again, you can get rid of most of the external concrete damage by noting the pilot drill penetration and moving the drill outside to finish.

These mini-splits are great, and even with inflation making them more expensive, still a better solution for many areas. I'm always a little worried about bending pipes, and would suggest a small pipe bending tool. Good job!

You can also get a bracket to mount the outside unit up on the wall of your house. I did this because where mine had to go was right near a driveway. But putting it up on a wall (above head height) means it won't get hit by lawnmowers, or covered with snow, and makes it harder to steal.

Had our HVAC provider install a Mitsubishi mini-split in our master bedroom last year...probably the single best home owner decision we've made. I considered the DIY MrCool system but went with the pros since it was a second story install.

A lot of people are confused about the line set and vacuum requirement. There are at least two options for this brand of A/C. One option comes with open line that must be cut to length, and nitrogen purged, pressure tested, and vacuumed. The other option ( The one shown here) has a line set that is sealed and pressurized with refrigerant and has special fittings that allow connection to both inside and outside units and does not require vacuum. Also, in both cases the condensing unit contains refrigerant that is released into the system when everything is connected.

Great tutorial!!
I'm a hvac technician and this explains it very well.
I hope this doesn't take my job lol

[icandreamstream]

Important to mention that you can skip the line set vacuuming / evacuation step ONLY with the MRCOOL DIY style units because their line sets are actually charged with the refrigerant. If you do this with other units you’ll have problems.

Installed the 36k btu model last year. It's really as easy as it looks. Including all the wiring and accessories I needed, came out to about $2, 400. I got quoted 6-7 grand to have one installed by an hvac company.

Once the center bit made that little hole on the outside, you should have taken your cement bit to the outside and finished the cut making it look nice.

When someone's basement is the size of your house 😢
Cool video nonetheless!

I am not sure why I watched this, I dont own a house. Your videos just make me feel good

Living in China for ten years, this kind of system was quite the norm. I've seen them install this in apartments 30 flights up on the outside of the apartment. I've seen them also do similar in large houses outside major cities. These fan units on the wall high up are so quiet, AND the unit outside is also unusually quiet. This how they zone their rooms. We should have this kind of system a long time ago. Thanks for bringing back memories.

Me doing this install (figuratively speaking)-
Day 1 - Unit shows up w/ mounting plate bent, and a dent in the main unit. Call manufacturer, they tell me to contact the shipping company. Contact the shipping company, they tell me to contact the Manufacture. Back to the shipping company to file a claim - 2 weeks later new unit shows up.
Day 15 - Rain
Day 16 - Slip and slide through mud digging out roots to level out base pad, takes ALL day - trek mud through the house when heading inside.
Day 17 - Rent carpet cleaner
Day 18 - Units leveled outside, head inside to find my spot - the ONLY spot is 21 feet away from the unit outside, a foot too far. Back outside to move unit/dig roots.
Day 19 - Time to mount that plate inside - Forgot my neighbor borrowed drill, he's not home.
Day 20 - Wife asks me what's taking so long, I never do anything!
Day 21 - All set, time to drill - need an extension cord. Head to shed and naturally it's on the back wall so pull out the Mower, 3 kiddie pools, 75 shovels/rakes, 45 lawn chairs, get attacked by a raccoon - start drooling - head to the Hospital.
Day 21 Continued - that night - Wife says "you going to leave all that stuff outside of the shed?".
Day 22 - Go to the basement to stare at the wall.
Day 53 - I Finish staring at the wall and decide to hire a contractor who specializes in ductless A/C units.

5:25 (tip) make sure the platform is level first and to make higher put more dirt or w/e the platform is going on. To lower you just take some material out and put the level on the platform first. It will make it much easier than doing it with the unit on the platform.
