Let's stay cool this summer, and warm in the winter. This is a DIY Mr. Cool mini-split heat pump. It will save me tons of money $$$ by installing this myself. No need to hire HVAC professionals. This is a unique model because the line set comes sealed from the factory. No special HVAC tools needed. This means I don't need gauges, vacuum pumps, nitrogen, tanks, or even a flaring tool. You will see just how easy this is in this video.
I'm replacing a 7-year old heat pump. It worked well for about 2 years, but was constantly breaking after that. Sometimes it would sit broken for a year while I saved up the money to hire professional HVAC companies to come in and fix the problem. In my area, just getting a company to come take a look at the broken system requires over $500 USD upfront. In total, I've spent over $5k USD on this broken heat pump. This is why I'm so thrilled that Mr. Cool has come out with a line of heat pumps that are designed specifically for DIY installations.

00:00It's springtime right now but the heat of summer is right around the corner so
00:05it's time to upgrade from my broken mini split heat pump to a brand new mr. cool
00:10heat pump but the best part this is DIY or do-it-yourself which is perfect for
00:16me so let's get going
00:22this is the electrical disconnect for the mini split now I've already turned
00:26off the circuit breaker inside the house but inside here is another
00:30disconnect so what you do is you pull this you can flip it over and if you
00:34flip it over then these copper tabs they go just into a plastic slot and they
00:39don't actually make connection with anything so that's a way to store it and
00:43there's now no electrical connection there shouldn't be any refrigerant still
00:48inside the lines because this has a leak about seven years ago I hired a local
00:53HVAC company to come out and install this Fujitsu heat pump it worked well
00:59for about two years before its first failure since then I've had three
01:06separate occasions where I've hired different HVAC companies to attempt to
01:12fix this in total I've spent over $5,000 trying to keep this heat pump working
01:21once that still didn't work that's when I tried to make some videos and do the
01:27repair myself still couldn't find the leak there's a leak somewhere in the
01:32system that's why I decided to go with a DIY route so mr. cool makes this DIY heat
01:41pump where you can put it together without needing specialized HVAC tools
01:46so I reached out to mr. cool and asked them to help with this video and they
01:52agreed so thank you mr. cool for that I built this concrete pad with these
02:02concrete risers in 4-inch PVC pipe to keep this up off the snow
02:16all right here's a nice cardboard template that came with the indoor unit
02:28so there's gonna be a metal bracket that goes on the wall and here's where they
02:33want me to cut out for the refrigerant lines and condensate to go through the
02:37wall so I'm just gonna use this and go around here and a few seconds later I
02:43think I'm done cutting that out here we go so now I can go put this up on the
02:51wall and line up this hole with the existing hole through the wall here's my
02:55existing hole through the wall from the old unit so I'm just gonna take the
02:59template now with the hole cut out I'm gonna line this up the new unit wants a
03:04larger hole than the old unit was so I'm gonna line up the bottom and cut it out
03:13and I'm gonna drill a little hole right here in the center where the mounting
03:22plate is going to attach we go so I'm going to use my drill bit and just put
03:30the drill bit in now there's no stud here so I'm just on the drywall but I'm
03:36going to use this as my pivot point now I can level this out back and forth and
03:41then I can mark for the other holes that need to be drilled there's some
03:46little arrows stamped on the template to the corners go so now we've got our four
03:55holes
04:05now put in these little drywall anchors
04:11right here is the stud I'm going to throw in one more structural screw at
04:28the stud
04:41with the mounting plate on the wall and the hole drilled you can actually see
04:55inside all the cellulose now this is a dense pack cellulose house and here the
05:01studs and cellulose this is what should occur if you have a properly dense pack
05:08wall this doesn't collapse it doesn't fall in on you if it's properly dense
05:13packed this is the indoor head unit so this is going to go inside the house and
05:18I have to bend these copper tubes out of the way so if they can go through the
05:24wall along with the electrical line and the condensate so I'm going to go ahead
05:28and do that now and I was pleasantly surprised when I pulled this back it
05:33looks like the copper refrigerant lines are wrapped in a steel spring to keep me
05:38from kink kinking them so they really did think this through as far as a DIY
06:34here's where the refrigerant lines came out the backside of the house the
06:38condensate is on the bottom that was an important part in the instructions and I
06:43spray foamed all up in there as far as I could reach inside the wall cavity using
06:49a low-density window and door foam I just screwed on this backer plate which
06:54is the first part of putting the cover over the lines
07:24I
07:54have some nylog
08:24so as you can see these are custom fittings the line set connections are
08:48complete so at this point we need to actually release the refrigerant and
08:51check for leaks so to do that we'll take these two dust caps off inside is a
08:59little valve and it has an allen key on it and they sent the allen key with it
09:03which is awesome so says to slowly open this and you might hear a hissing sound
09:11yeah very very slight little hissing sound there it says open it all the way
09:22now we'll open up the bottom one and open its valve
09:42to check for leaks with soapy water or what I'm going to use I have some leak
09:49detection fluid we're watching for any bubbles okay up top we're spraying these
10:06ones down and we're looking for any leaks and I don't see any now something
10:09that really impressed me about these refrigerant lines is they're wrapped in
10:13this metal spiral spring and that is an anti kink it keeps you from bending it
10:20too tight and that's really awesome that they added that in the package they
10:27included some sound dampening material to go around these valves this reminds
10:34me of what you might use like a car audio to dampen the panels of a car
10:50they included a little extra insulation
11:05inside the package for the vinyl cover came these little black plastic clips
11:12and I wasn't sure what they are for at first but it looks like they snap in
11:16here
11:23that
11:26so I'm using this tape that they provided it's not really a tape so much
11:49as a vinyl wrap so I'm wrapping it around everything right before I exit
11:55this vinyl channel all right so I zip tied it with a little clip that they
11:59provide and I have to finish putting this cover on but right now this drip
12:03tube I don't actually want to go all the way down to the ground so I'm just going
12:08to cut it off and now that'll drip out I don't want to put stress on these brass
12:16fittings
12:46this whip has an extra red wire for 240 volt we don't need that
13:00okay red white black it all looks good so just like the color photo shows us
13:31so this is called a smart HVAC controller and it looks like a USB flash
13:47drive and this should allow for hooking up to your smartphone so that goes right
13:57up in here now that everything's done we'll just flip this over I'm gonna go
14:17to the Google Play Store because there's an app for the phone mr. cool smart HVAC
14:25we'll install that so let's see if we can turn it on with this remote it has a
14:34display under there I didn't know it did that so here's the app on the phone
14:42all right it just beeped and connected up I think I told it 68 degrees
14:49Fahrenheit in dry mode it's been running for a few minutes now let's see what the
14:55temperature says 42 40 38 this is in Fahrenheit 4 Celsius zero I think that's
15:09it as you can tell it's very quiet I'm thrilled it's working I don't see
15:14anything leaking I don't hear any hissing this is awesome so thank you very much mr.
