@Silver Cymbal thanks for the post . Question can u connect one end of the quick connect line and come back a day and connect the other end to the condenser? Also when u first connected the 25ft line to the air handler from the hole did you hear any gas been release while tightening the first connection ? I just connected the first section to the air handler and heard the gas been release . It got dark and I couldn’t connect the other section to the condenser. Will connect the other section to the condenser in the morning. I am setting up a 4zone 12,12,12&9 k to a 36k condenser.

I installed 2 ton mini-split heat pump in my garage in 2019, and it's been one of the best investments I have ever made in my home. It is so nice to be able to turn the garage into a meat locker on those hot days, melt the snow and slush in the winter. You will be amazed at the moisture-removing power, even in heat mode. One thing to look out for - the brand I chose (not Mr cool) has a minimum set temperature of 60 degrees while in heat mode. I would prefer something in the 45-50 range for a garage application, just enough for snow melting and freeze protection. Maintaining 60 on a 5-degree day definitely burns some electricity. On those arctic days, it can cost as much as $15 / day. On the typical 25-35 degree days we have in Cleveland, I'm adding about $5 / day to my electric bill. For reference, my garage is fully insulated, including doors. In summary, try to find a unit that allows a wide set temp range.

Purchased: August 2023 - still works GREAT!I kzbin.infoUgkxxsUnXhGsSJLim_XnMHyQK0u3XVaW-CGn live in a studio and during the summer it gets scorching hot - really old building with no ac units. I can’t express how EASY it was to install. This unit has been a life savior during the summer and some days during other seasons where it can still be a bit warm at night. In this small place is my friend, a husky, poodle mix and myself. We need AC - lolI don’t use the dehumidifier option - I’m not sure if it will leak in my house, since I did not install the small draining hose that came with it. May look into it late but I don’t worry about much humidity in the apartment. I don’t understand why the negative reviews since all things mentioned, I personally did not find issues with. Definitely worth it!

[@Pallidus_Rider]

To discourage mice, use steel wool with the expanding foam 💡

[@SilverCymbal]

That's an awesome tip thank you

[@truthbinder]

Or copper since it won't rust.

[@Lierofox]

Did the same thing with my A/C install for the tubing sleeve. And pretty much any time I have a passage going from interior to exterior with extra space in it (for example, I also have a piece of conduit running through my wall for amateur radio antenna coax) I plug the remaining space up with stainless steel wool.

[@Mark-zi4dd]

They also make an expanding foam with something in it that discourages rodents from chewing it, but I'd use copper or SS mesh too.

I installed the 24,000 BTU, probably identical to the one shown here. It saved my butt this week after power outages during hurricane Ida in South Louisiana. The unit runs fine on almost any generator. The variable speed compressor doesn't have a surge upon start-up. It slowly increases compressor power. These units are super efficient. I didn't get the collar that goes through the wall with mine...I need to call the company.

[@jmat7103]

I would like to know the why too

[@answernotfound5278]

@@prodriguez3290 because if coiled vertical, the oil that circulates thru the lies will become trapped and useless. The oil is for the compressor. If this oil isn’t in the compressor it will cease up. At all costs please coil it horizontally, it seams so simple but it will make all the difference.

My experience with mini-splits is they are much better coolers than heaters. We use four of them in our place in Mazatlan, SIN, MX, where heating is never an issue since it NEVER gets cold. However, in Vancouver, BC, CAN, my daughter uses mini-splits in her place but needs additional (baseboard) heat in the winter when it can get as low as -5°C

[@MandoFettOG]

I installed a mini split in my garage (Man Cave with insulation) in Phoenix AZ 2 years ago and during the summer it is the coldest place in my house at 72 degrees we always need a blanket to watch TV while in that space and it is very quiet inside and out and with the 220 volt system it actually brought my electric bill down $40 per month!!

Great topic and yes..congrats on the half million mark!!

[@ahkeen]

[@topperdude2007]

Great quality for BOTH the mini split install AND (as always) the quality of the video which was to the point with all the information someone watching would need without unnecessary fluff to get to the 10 minute mark. I would very much appreciate a follow-up video with how the mini split performed during winter. I also live in similar climate (Minneapolis) and have been seriously considering these. All of the local HVAC people that I have talked to seem to want to discourage folks from using mini splits saying they do not work as well in winter. On the contrary, I have seen first hand mini splits work quite well in other parts of the world as well as videos on youtube showing entire homes being heated/cooled by multi zone mini splits in Canada - which leads me to believe that the technology has matured sufficiently to serve both heating and cooling duties. I do have a large-ish garage space - almost 800 sq ft 3-car garage with 12 foot ceilings. So I am guessing I will need to invest in a slightly larger capacity (18k or 24k BTU?) unit. But I reckon if your friend can use a mini split for their basement (i.e. in a large living space), I should be able to find one with capacity to heat and cool my garage. I should note that my garage exterior walls and garage doors are insulated. Thanks for the great video and hopefully can get some input on how well these work for heating in really cold climates.

[@batbawls]

Safe, clean, proper install. Very nice.

[@dang6832]

I’ve seen a couple videos like this, but I felt a little better informed after watching yours. Thanks for keeping it simple but thorough. Looking to build and I want at least 1-2 of these units for a garage and an electrical room for solar with lithium batteries that don’t like temperature extremes and a pool pump. Possibly 3 depending on the garage size. This is of course still a dream until done.

[@SilverCymbal]

I really appreciate it, I had made another video with my friend but I wanted to see if I could do the whole job alone, its definitely doable, just go at your own pace.

I work in HVAC and install these for a lot of people, never once do I get complaints about the system. They are very easy to install alone but we use Mitsubishi units which don't come with prefilled line sets because they can reach 50ft. Good video!!

[@pba21]

Lovely. Nice work!!

[@geedoubleu641]

I installed a 12K unit and love it. If you install a heat pump AC in a cold climate the heating might not be sufficient during long cold spells. I believe the unit would need an electric heating element to keep you warm. Also, it's important when cutting through the wall to angle the hole downward from inside to outside. Mini split systems are notorious for condensate dripping from the indoor unit (air handler) due to drain lines not dropping sufficiently.

[@kevinwiley5325]

Great work on the install. I shopped around for a minisplit unit and got an Evermore unit from a FB Marketplace reference for 300 bucks and did the install. It's not as fancy as the Mr. Cool, but it's 1700 cheaper!

[@yomomma9070]

Nice job. I would recommend cutting the refrigerant tubing to fit and reflare the ends. You would have to pull a vacuum on the tubing and the indoor unit though. In the world of refrigeration we are taught that the system is most efficient with the shortest possible interconnecting tubing and the smallest refrigerant charge. You would've probably had to remove some of the refrigerant due to the back to back installation. Some systems can tolerate small overcharges and some are temperamental.

[@thomasrossi31]

I have the same unit. Installed it in my new detached garage (22x25 with 13’ ceiling). Works great! AC is probably more effective and efficient than the heated.. but, the heater makes it comfortable in those dreary winter months hear in the North East.

How does the Mr Cool brand manage warranty on their units? When I was looking to install a mini-split in my Northern Florida garage last year, I was always told that you can install your own unit, but that the manufacturer would not provide a warranty for it. Great job overall; nice and neat work.
