DIY Multi-Zone Ductless Mini Split AC & Heating System | MR Cool Install 2021

The only thing you are missing is a surge protector for your minisplit. You should install a Ditek DTK120/240 surge protector on your cutout switch so that in the event a lightning strike or power company surge happens your sensitive electronic control boards in the minisplit aren't toasted.

Can you keep the two rooms on different a/c settings……. One at 75 degrees and the other at 79 degrees?

The hole has to be kinda lower beacuse water might leak back to the inisde unit

Do these things really use less electricity than the wall units

On my way to buy some

Had to find a different video...this guy's voice is just freaking horrible

Super simple and anyone can do it, all you need is two hvac techs and one electrician.

You got all that free? 😮😢

Biggest air handler needs to go on the A ports.

How come you didn’t vacuum the system down before charging the system? A real HVAC guy would have vacuumed the system to test for leaks prior to charging the system.

You don’t need hvac back ground it’s simple connections did few

This is interesting

Line set do not come pre charged

How does that bend affect power cable? Heat accumulation, heat dissipation around it

So you happen to be in an expensive electric state, what has been your elec bill? is it different from the window units? Is it more efficient and keep up even though your are hitting high triple teen degrees?

Do you want the air to blow away from the house (compressor)?

Notice how people are allowed to share experiences here. Comments aren't closed like any solar ad. Because Solar is a big ole scam that will cost you thousands

What did you use to hide the copper ac lines coming out of the house?

The big box stores, and local electricians are charging upwards of $9000-20,000 to do these. It is outrageous.They have a monopoly because of the city requires stupid permits.

On the insulating tape: You didn't peel off the clear plastic from one side of the tape. If you had, it would have stuck to itself very well!

Don’t need to vaccum Line set ?

He should have just used the plastic instead of the concrete, saves hours if not days

Lewis!! ... 50 points for whoever gets it.

Great

lol

Pretty amazing it worked, considering you never showed opening up the master valves above the head unit valves to release the refrigerant.. hmmmm

All that beautiful sunshine! I wonder where that location is

2 steps were do it yourself. The rest is Hella hard shyt for pros.

So how is your cost analysis going ???

Let me know when and where you put these in. Would love $10k from EPA

forgot to pull a Vacumm

Don't vertical loop line set. Eventually it'll trap oil.

Did you triple evacuate the refrigerant system to 500 microns and hold for at least 30 minutes to remove non-condensible air and water vapor? If not system will have higher head pressure using more power and acid and sludge will form causing premature compressor failure.

Wooo hella lotta work. I don't think that is a diy for me

How well do you think this system will cool an attic?

Did you pull vacuum from the lines to get rid of the moisture that exists in the ambient air? In my projects I had kept the vacuum pump running for at least half an hour before letting the refrigerant in. Maybe that’s not needed where you live? Looks pretty dry out there 🙂

Thank babe for the video much appreciated x

that looks really nice at the end tho

omg why....this is soooo bad lmfao.....does mr cool not require you to leak check with nitrogen and pull a vacuum???? there has to be moisture in those lines

That is not a French Drain, a French Drain uses a pipe underground that has holes in it to absorb groundwater, what you did for the condensation, is a mini representation of a dry well

My sister lives in a old house no ac and right now no heat. (Thieves stole all copper they could before she moved in) im moving in with her and think 1st thing is upgrading her electric before looking at these. Thanks for this.

How big the slab? How long is pipe line to compressor to wall unit? Do you know what is the difference between the Generations Mr Cool? I am thinking get 3rd Generation.

This is a ghetto diy install. Oversized holes. No grommets , ugly linesets. Man its bad

Cool!

Hard stretch to say this is DIY when you have HVAC professionals helping you...

It’s been a year since posting this video. Any word on the electricity bill? I’m considering getting a couple of these for a house remodel. Very little to no snow in my area but a lot of great comments of things to keep in mind, mainly have an HVAC guy handy and don’t leave extra line coiled up. But, I’m very interested in how this impacted the electric bill. I can’t find anyone that has one who shared the difference it makes on the electric bill, good or bad.

cool, good job. now you can paint then white overs to match the wall and you would never realize.

What were the efficiency results?

Imagine shilling for this trash.
