I Installed A Heat Pump In My Garage! (MRCOOL DIY Mini Split 3rd Gen)

[@linang2211]

Finally got it up and running. The only delays we had was because we realized we needed some extra parts (I’ll list that below) kzbin.infoUgkxihMYiJNXcHdbH-7ihymsLz61l7jVyb5O . So we have a loft where our current hvac just couldn’t seem to keep cool during the summer. We have been using a window unit since we bought this house over 6 years ago (all the houses in this neighborhood were built in the 80’s and majority of the houses built like ours use a window unit). I hate window units because they are just so noisy and the one we had really only cools one side of the loft. I had contemplated upgrading our current HVAC, but with all the rising prices these days, it would take years before saving up enough to do that. With the advice of my father-in-law (used to run an HVAC business), he recommended we get an inverter instead. We thought we bought everything we needed, but there were just a few other parts we didn’t anticipate needing (which is what caused most of our delay). My friend and father-in-law did all the work to get it installed and running and now we have nice cool air circulating nicely throughout the entire loft. It is very quiet and even the outside unit is much quieter than our main HVAC unit. Saved ourselves thousands getting this.

FYI, you checked the line set on the top section with soap and water, but you must have the refrigeration in the line to see if you have a leak, do this once you have the refrigerant in the lines in order to check for leaks, other than that, you did great. Thank you for posting

[@johnturner9924]

these lines come precharged

[@55afishead]

@@johnturner9924: Joe is saying you check the lines for leaks after you open the valves at the compressor. Not before. There is literally nothing to check. The lines come precharged means they are under vacuum. So when you open the valves at the compressor the lines become filled with the freeon. Then you check for leaks.

[@johnturner9924]

@@55afishead That was what I was saying.

[@keenanwalker6597]

Make sure you always drill hole and angle downwards the drain needs pitch otherwise your units drain on will fill up and drip down inside of your wall. Very important

[@envieddesigns]

also In the manual it says to remove the filter and pour some water to verify that the water exits through the drain hose and does not sit in the unit. Has anyone done this? I opened up the front cover and removed the filter, are you supposed to pour the water over the fins ?

[@JM-lw3nx]

I doubt it would make a big difference in that thin wall, so relax

[@ccek00]

These are great diy units and it looks like people made some small recommendations to ensure your drain worked and there were no leaks. But anyone reading this please put your heat pump on a stand so if you have leftover pipe you can put it horizontally underneath. Having the role stand up that way vertically behind the unit causes areas for the oil that is added to the gas to collect. After some time this can be a cause of issues that include your compressor breaking down.

[@imkindofabigdeal4308]

Just an FYI. We installed the non-DIY. Much much cheaper. All you need to do is nitrogen purge/vacuum the lines after hookup. The freon (410a) is already pre-loaded in the compressor. Our A/C guy did the last step for us - about 20 minutes of work. Our garage workshop is now awesome.

[@JasonExplainsThings]

Great advice.

Not Freon! That went away! It’s Puron or just R410a! Freon is a registered trade mark of DuPont.

Great presentation, you've got a knack for making videos.

[@galenledbetter8014]

Welcome to the MRCOOL family! Your tutorial and install looks great. I also installed the 18K unit in my garage and shortly became the envy of my hood. With that said, I must share some info a few HVAC friends offered me. It was strongly suggested to me to not leave any excessive amount of the line set coiled during operation. This can create an improper oil trap on the suction line that will restrict proper flow to the condenser/compressor. Happy Cooling...

[@T6Tarek]

Only issue with the Mr cool diy kit is that the line sets already have the vacuum pulled so if you cut the lines to not leave the excess coiled up you'll then have to buy a vacuum pump and gauge set. You'll also then need to purge the system with nitrogen. So to keep it truly diy you'll most likely have some extra line set.

[@galenledbetter8014]

Plz don’t cut if you bought a DIY kit unless you want to recharge. You have to expand the excess line set somewhere, somehow. I choose to uncoil mine into the attic

[@briandbeaudin9166]

Just make sure the excess coil is stored in a horizontal orientation to avoid the oil trap situation

[@ellismckinney4888]

Hello is the bulky white sheath necessary to keep? I assume its for insulation? Just seems very bulky. Ty

[@galenledbetter8014]

Like you, I can only assume the sheathing/white foam has insulating properties. Not sure if removing could void any warranty issues down the road. I will offer that as I plumbed mine through the wall and into the attic to my outside unit, some of the sheathing was torn. My section of line set that is exposed to the outside elements still has this insulation. I also chose to camouflage it with a PVC line set cover kit. You can scoop this up from your friends at Amazon.

[@markrouse2416]

Third gen does not have charged lines so it is best to check for leaks only after opening the freon lines with the allen wrench.

[@adamgusse9484]

I am going to ask a couple questions based on comments as well as a few myself. Any and all input from anyone will be appreciated. 1. I see you and others say they are pre-charged. Which is great... but what is holding the charge? When you hook them up... is there a seal on the inside that breaks when you tighten down the fitting(s)? One person below said it comes pre-charged with nitrogen. ??? If the unit is 410A where does the nitrogen go??? I dont think nitrogen would be the charge. That is usually used for pressure testing. It seems to me it would be pre-charged with 410A. But my main point/question is.... I am trying to determine how and why it is not really necessary to pull a vacuum. If there is no valve(s) on either end of the line sets.... like the cond unit itself.... what is holding the charge? Both on the line sets and the inside unit as well? 2. Has anyone pulled an amp draw on these to see exactly how many amps it pulls at peak start up as well when running? It would be nice to know.

[@JasonExplainsThings]

1. Yes there is a seal inside that opens. You can hear it when it happens. 2. Download the installation instructions and you’ll have the answer. I installed a 30 AMP breaker, but that is likely overkill.

[@adamgusse9484]

@@JasonExplainsThings Thanks! It would probably be clear as daylight if I saw it with my own eyes. But then I would have to buy it to see it. lol Anyways.... I saw that it will only be about 12 Amps probably 15 amps over time with wear and tear. I would definitely say 30 amps is not good. Improper protection. The larger the breaker the less protection you have. You may want to consider downsizing to 20 amp. Something may happen and You may be pulling more than 20 amps enough to ruin the unit or burn up a wire but not trip the breaker. Something to think about. But thanks again for info.... I come from refrigeration industry and I was trying to make sense of what held the pressured refrigerant inside but what would allow it to flow after connecting. SO there had to be a seal of some sort that once fully tightened would break that seal to let refrigerant flow. It would be advantageous for them to explain this to people. Probably would help sell a LOT more units... and more importantly.... keep a lot of negative comments down.... from people in the refrigeration industry (such as myself) and a lot of questions answered before asking... Thanks again!!!!

[@kevin9c1]

You can tell he didn't really read the directions. Lineset from inside unit should have been taped with condensate tube at the bottom. Hole through wall should have been drilled at slight downward angle. Not supposed to button up lines until you connect to the condenser and open the refrigerant valves. Only then does checking for leaks do anything. I have installed the same system, and this weekend I will be finishing up a second install (18k dual zone). You CAN disconnect the lines as long as you first shut both refrigerant valves on the condenser. I know, because I had to replace my gen 3 18k condenser (under warranty).

[@slipstreamvids7422]

Both inside and outside are condenser depending if in heat or cool mode. As such they both have to drain.

[@Cr0tchG0blin]

I know this is late, but what do you think about the 1981 d150?

[@Troc313]

Hello, was looking at this mini split unit for my garage. I have a 800sf garage, was thinking to go with the 2 ton, but I need it more for heating the A/C, how is the heating in this unit, and is it possible to install indoors in garage attic? And if anyone who has used this unit, how is it overall?

[@robbie6625]

Did you figure things out yet?

[@damrgee8279]

We have an 18,000 BTU Mr. cool mini split. With the heater on the unit seems to go on and off is this normal? And the unit is not perfectly quiet is that normal? I have been searching videos and articles but cannot find any answers thank you for any input

[@JasonExplainsThings]

I can hear it click on and off while heating. It's pretty darn quiet for me. About the same volume as a small desk fan. I'd check to see if you have dust buildup or something.

Thanks for the info good job explaining everything 🕎🕎

Thanks!

[@bosada2960]

Hi. Can you explain why you chose 18k vs 12k. your shop looks like less than 500sqft?

[@JasonExplainsThings]

Sure, so my shop is 576 sq ft. The 12k is rated for a max square feet of 500. Especially since this is a shop/garage with large older doors I wanted to have overkill instead of going past the capacity of the heat pump. If it was under 500 I would’ve gone with the 12 k.

[@bosada2960]

Thanks! Love your channel!

LOL you will need an HVAC tech if you want warranty....love the DIY and warranty conflict...have fun.

[@mikeberger1688]

Is Mr Cool the only choice for self-charged diy systems?

[@JasonExplainsThings]

It’s the only option I’m aware of. Holding up nicely 6 months later.

[@Chef_Frank]

I have disconnected the lines to move the unit forgot to close the lines now I gotta see what’s going to happen. Also what refrigerant is needed in case I need to refill and anyone else not getting enough heat it’s just warm

[@T6Tarek]

Even if you close the lines you'll still loose refrigerant due to what's in the lines and indoor unit. You will now have to pull a vacuum and evacuate the whole system or you'll will have tons of issues, and you'll most likely not get very much heating and cooling. The refrigerant needed is 410a. You will need to se how much the system requires and have a accurate amount put in the system, this requires special tools. By disconnecting the system you have now made to where you will need a professional or a lot of special tools and the knowledge of hvac

[@Chris_junya]

Once you do that you have to hire a professional, handling refrigerant requires a EPA license which usually hvac professional carries.

[@ducharmehvactraining925]

Use a torque wrench. the specs are in the manual. If you get snow raise the outdoor unit. coil the extra piping horizontally so as not to cause an oil trap. talk about maintenance

[@VanillaGorilla502]

Total cost?

[@JasonExplainsThings]

Didn't include an exact price because it fluctuates a lot. Links in the description go right to it.

[@AZTechLabs]

You could have bought the 16' hose rather than the 25'. Losing heat/cooling through that extra hose.

[@JasonExplainsThings]

That wasn’t an option with Lowe’s, but yeah that would be great.

[@bobw3677]

@@JasonExplainsThings Home Depot gives many more options for hose length. For instance on a dual zone unit it will be labeled 1675 which means one 16 foot line and one 75 foot line. Right now, Lowes does not give you these options.

[@roberthughes9773]

I guess you now know you checked for the leak on the downspout line when there was no refrigerant in it. You said the "line" was pre-charged. Nope. The outdoor unit was pre-charged and until you opened the allen key value, there was no refrigerant in the line you previously checked for a leak.

[@SomeNameGoesHere]

So you know more than the manufacturer? I hope you called them up to correct them. mrcool.com/blog/pre-charged-line-sets-real-right/

so why are you just repeating what others said? fell better?

[@SLY1SLICK3WICKED]

hey great job on this video! my question to you is how hight and low can you set the temp? I WANT TO BUY THIS BUT HAVE THAT MAIN QUESTION

[@JasonExplainsThings]

For really specific instructions check out the linked PDF. I briefly talk about it in the video that you want (if I remember correctly) at least 6 inches from the ceiling. But the instructions go over that.

[@SLY1SLICK3WICKED]

@@JasonExplainsThings I'm so sorry i fat fingered that lol how HIGH and low does the temp range? well your from WA state as am i, i was looking for a HVAC that can heat and cool. that being said does this do both? ALSO your videos are awesome man

[@Manupicho]

Your outdoor unit seems awfully close to your neighbor's wall. About as close as I want to put mine (Pionneer - about 55db) to my neighbor's bedroom... How loud is the outdoor unit? Did your neighbor hear anything?

[@JasonExplainsThings]

Not my neighbor... that’s just the side of my house (installed in a shop). 👍

[@JasonExplainsThings]

Its also pretty darn quiet.

[@Manupicho]

@@JasonExplainsThings and so you do not hear that outdoor unit from inside your house? that'd be darn amazing indeed (I am just really concerned for my neighbor and how close 15ft this unit will be from their bedroom). Thanks!

[@T6Tarek]

It's no different then having a heat pump, people have them across the usa, can you occasionally hear them? Yes. Are they loud and annoying? Honestly no. They are really quite and rarely hear anything. Occasionally if it goes into defrost mode you may hear it that's about it. If you get permits and it's approved there isn't much the neighbors can say. Not to mention these are used in Europe and Asia where you will see 100s of them mounted to the sides of high rise apartment buildings.

[@psychodocter]

Gr8! TY!

[@bk111213]

Is the indoor unit powered from the outside unit via the “communications wires” or does it require it’s own separate power supply?

[@JasonExplainsThings]

The wiring from indoor to outdoor includes power.

Engagement is engagement. :-) But it is funny how angry people get about this video... thinking I made everything up. I'm just following the instructions and showing the results. The heat pump is going strong a year later. I love it.

[@bigblue3568]

7:00 refrigerant lines are not pre-charged. 410A charge is inside the condenser unit. Don't care for having several feet of line just coiled up outside. I would cut lines to length and braise on new fittings.

[@JasonExplainsThings]

Wrong. To find the answer all you need to do is check the instruction pdf I linked too in the description.
