Mr Cool Ducted Systems (Hyper Heat) - mrcool.com/cen...
I just completed a full installation of a Mr Cool (36,000 BTU) Ducted Hyper Heat Unit. This is an all-electric heat pump that is DIY-friendly and can save you a TON of money. In this video, I will walk you through how long this installation took me, how many trips I took to the hardware store, and the total cost/savings for this unit.

Former HVAC Tech here. Good job but i do have a couple of things to point out. You need to run the insulation on the lines all the way up to the unit,at least on the suction line, so condensation doesn't form. And you should put a clean out on the drain.
Great feedback appreciate the help 👍
Awesome! Thank you!
You tell him what an amateur
I assume there was a trap but couldn't see it.
@@harrybaulz666trolling on UA-cam is awkward.
I’m a big fan of the Mr Cool universal. I am a preservationists restoring 200 year old homes and these have been amazing. I can’t wait to watch your installation video.
@@Bryan-Hensley they are expensive compared to other units. I have an EPA 608 so I am able to handle refrigerants but the idea of Pre-charged lines and DIY is exciting considering HVAC and the industry is coveted.
This is EXACTLY why I DIY everything I can. Over $7000 is a massive savings. Very informative Scott. Excellent content 👏
Thanks Josh 👊
@@Bryan-Hensley how would they find out?
Don't think this is a quality installation, and what are your temp rise, drop?
Are you 9"+ off the wall? Performance ? Is the question?
@@petermoore7500 one could come on and pick it apart but a diy guy could always install it and get it running and then call a tech out to set superheat/sub cooling to perfection. A diy that takes on this type of project tends to be very cautious to begin with. When I first began diy units on my rentals, I paid a tech 750.00 to watch and correct me. Because I had multiple units I got more practice than the average guy. My diagnostic skills aren't great but with UA-cam videos it has helped me a great deal. For me though.....once I start having issues with older units....I find it better to just replace them and be done. It buys me 10 years of mostly trouble free, other than caps, time.
You detailed the costs great ! Very nice explanation! Will check out the installation video also . 👏
Enjoy, It’s a long one 😅
Scott you're a great presenter, and a big help to a lot of people. If I could ask a favor from you. I just installed the same unit, with the same thermostat. But I would like to use my Nest (gen3) instead. On page 39-40 in the MrCool manual it shows all the wiring diagrams. If I could ask you for your opinion on which one I should use for the Nest it would be a big help to me. Thank you.
Whoa, Mr. cool getting into ducted full size split units. This is awesome!
Yeah, they are really expanding the lineup.
They've had them for a few years now, but love to see them expand and especially release models specifically for their pre-charged linesets! I installed a MrCool Signature series about 4 years ago and it works excellent, no regrets at all with MrCool
Experience has taught me that replacing a furnace with a heat pump, especially in cold country is a reciepe for disaster. A 15a circuit means there are no back up strips. And, although the mini-splits are better at producing heat at lower OD temps, they aren't magic boxes. Further, good luck ordering parts when it's 10*F outside. Most minisplits are "disposable" units.
To be honest I am interested to see how the unit does in the winter. You are correct no heat strips/coils so it will just be what the heat pump can produce this winter. I will make a couple update videos documenting the performance and energy consumption.
Great video, Scott. Really appreciate the practical breakdown. Thanks.
bro is a god send. always helping out and making the videos easy to follow.
Here to help, thanks for the feedback 👍
HVAC tech here. Just a few things to point out. First the suction line should be insulated all the way to the unit. Second, you really need a P trap on the drain with a clean out. That style of unit has the coil in a negative pressure from the blower and so without a trap the water won't be able to overcome the pressure to drain. Finally, and this is my biggest concern, I would see if your ductwork is properly insulated. Since it appears the system was heating only before, the ductwork may not be insulated. If it isn't, it may sweat in the cooling mode and cause mold in the walls
What about the fact he’s using a non vac lines. Every line should be vacuumed including the coil
Thanks for your videos, just want to say, your sound is great, even in the basement.
Thanks for the feedback 👍
I'd like to see a step by step full install video (maybe multi part) of the whole process!
Here ya go! ua-cam.com/video/JKcvUjD9NrU/v-deo.html
Thank you so much. I'm about to start this very same project!
Best of luck 👍
Here is another consideration. Using a ducted system allows you to use a real air filter which is potentially a game changer compared to the ductless systems. They do also allow for backup resistive heating even though it's a huge energy suck. Overall, even without the heat strips, they are a lot less efficient than ductless. The blowers draw more power (way more work to suck air through the restrictive filter and blow it through long ductwork), and the ductwork itself is lossy. So for max efficiency I'd recommend ductless plus in-room HEPA filtration as needed. Ductless also gives you zone control to a level that you cannot practically get with a ducted system. The downside of this is if your house has a lot of rooms, if you don't have a mini-split in each room, you would probably have more even heating/cooling with a ducted system.
Awesome video! Wondering if you installed a Low Ambient kit on this unit? If so could you possibly provide a video showing the install process? I am running into issues with the provided connectors.
9.22.23 Very good Scott. I am going to watch the hour long install. Thanks again
What I want to know is the quality of their equipment and coils. I've been eyeing them soon to replace my 20 year old system. My ductwork and electrical is already setup for this purpose, so install would be easy. More concerned with longevity of the equipment. Not saving anything if coils leak or things start to fail in 5 years. Warranty seems great, until you factor in refrigerant and technician costs to come repair it.
You need to check on the other brands as they only offer 1 year on labor and after that you pay for the refrigerant and technician costs to come repair it.
Terrible brand don't do it. It's made in China. Mine broke several times. Coil leaked after 6 months from new
The problem is you won't be able to find someone to service these units. Try getting parts as well, it won't happen. As an HVAC technician with over 30 years in the trade, I wouldn't touch them. It's a bad move even if you save a little on the front end. Wouldn't you rather spend what it's supposed to cost and have peace of mind?
I really appreciate this video. The complete cost analysis is greatly helpfull, even if that's not what I could do (no central air vent etc). Thank you man. Keep that kind of job.
Suggestion : you could explain how to protect your asphalt driveaway from winter ? Here (QC) most people do it regularly, but I'm not too comfortable with that. Is it efficient ? Is it hard ? etc.
Hi Scott, Looks good. How did you handle the electric and HVAC permits, inspections and green stickers from your AHJ's. Insurance companies look for those if claims come up.
I love how hvac techs and companies need a license to even touch a unit but these idiots can sell to Joe blow then call us wanting to bail them out for pennies
Thank you for your video, great job. It’s really usefull for the DIY.👍
# of trips back to the store ... ooh yeah that one hurts! Scott I appreciate the disclaimers you always include. For these large projects it might be good to remind viewers you're not always working on your own home, when considering their expectations.
It would be so nice to have that type of installation, but down here in the South the HVAC is installed in the attic, and it's horizontal too, so that would be quite the chore. I still don't know how the builders got the unit up there in the first place. It's right at the top of the attic pull-down ladder, and it's perpendicular to the opening as well.
Yeah, getting the air handler up there would be a challenge for sure
Well done. Personal I dare not to do it myself even though you explained very well.
Thanks for the feedback and I will admit this is on the upper range of DIY.
I live in Co. With a heat pump it will heat the entire house to -20 F. Hasn’t been colder than that here. 3500 SF.
HAVE FUN SAVING YOUR MONEY! But when it has problems and quits working, you are on your own! No HVAC company will come out and work on a DIY system! They are crap and no company that is worth there weight will touch them!
I live in Minnesota and will be very interested in winter performance...
good for you.👍🏼
I would say that at least 95%+ of the people watching this video would not possess the time, willingness to purchase new tools, adequate knowledge, skills, helpers needed, motivation, etc...in order to save on professional install labor fees.
And even if they might install it on their own, later ....post install, as mentioned, getting parts in the middle of a massive heat waver or super cold blizzard...wont be easy, nor will finding a licensed HVAC guy... that would agree to touch a DIY whole house HVAC system issue.
So yes you did a good job on your own installing this system!..... but it's not realistic for most folks to install their own whole house unit.
Had a buddy install his own natural gas downdraft and saved 7 grand. He showed me some of the prior "proffesional hvac work" including two exhaust pvc that should have been cpvc on the exhaust that had not been primed or glue correctly and were only held on by less than 1/4". Total crap workmanship so he had no qualms doing it himself, all tested and approved. But a BIG job for your average DIY and of course very dangerous.
Is there warranty on parts if it’s a diy project though? I know when professionals install it that most bigger brands have 10 year warrant on parts
This Hyper Heat version of the Mr Cool ducted systems also has a 10 year parts and labor warranty. If the No Vac refrigerant lines as used a professional is not needed during install to keep the warranty. Also good to note this warranty is non-transferable.
"Warranty void if removed" stickers are illegal!
@@EverydayHomeRepairs labor warranty? I don’t think so
@@joeshearer1247 I think that is the labor associated to swapping out a bad part from a manufacturing and workmanship perspective.
In order to get the 10 years you have to have it installed by a technician it's on the fine print LoL
Awesome video! Respect! Question: I know it's different in every town but aren't there inspections required once completed (at least for the electric and natural gas)?
Great video. More detail would be awesome!
Well, you are in luck ua-cam.com/video/JKcvUjD9NrU/v-deo.html Enjoy 👍
Awesome! Thank you. Great videos, keep'em coming. @@EverydayHomeRepairs
I love seeing videos like this of DIY HVAC being posted. I would like to see an educational video on the whole installation especially the custom duct work.
BTW, I bet the crooked HVAC techs are fuming.😂.
There is an hour long video linked at the very end of this video and I will also publish the full installation this coming Sat 👍
Let's keep respect for folks in the trades. Those jobs are hard work to keep at day after day, year after year. While their hourly rate may be high, their paid hours are often well under 40 hours per week because many do free estimates, many of which produce no work. So someone listing a $180 per hour rate might really only be pulling in $80 per hour of actual work, and then they have all their business costs and self-employment taxes.
And if you think it's a lucrative option, I'd encourage you to join the trades! While I'm not in the trades, the DIY projects that I do sure makes me respect what they do and the skills they bring to do it much more efficiently than me.
Its hard to tell from the video, but did you remember to put a trap on the white pvc condensate line?
I forgot to point that out.
Do you have a video on replacing a gas furnace for electric?
That is basically what happened in this case except instead of a gas furnace it was an oil burning furnace. Here is the complete installation video ua-cam.com/video/JKcvUjD9NrU/v-deo.html
I agree with Scott. Big savings. I am surprised your quote was only $12000. Was the custom ductwork and electrical with included in your quote? The other thing is permitting. Where I live, only a licensed individual can apply for a mechanical and electrical permit. If I do faulty electrical work and it causes a fire, homeowners may not cover if the work was done without a permit. I think the hvac is low risk but the electrical 240v line is something I am not sure about. How do things with in your Illinois for permitting and is that something you did? There is also a cost for the permit you have to include. If there was a gas furnace involved with the hvac then that changes everything about getting a mechanical permit. What are your thoughts?
Good job man!
Thanks!
Wow! Amazing!
Thank you!
Received a quote and apparently I need to take out a mortgage to pay for a 3 ton heat pump split system on my central system that I already have.
How has it been performing for you? Is the build quality ok? I feel like I"m missing something because the quotes I've gotten to install and purchase a MR. Cool by a pro installer is like half of other units.. Is it that much lower quality or is it 'good enough'
I'm wondering what kind of electric bill savings one can expect from going to this setup from an old R22 home AC.
Yes, I'd love more details on your installation.
Actually, why don't you just drive down here and we can install a new one together at my place.
Besides ice cold beer, how do you like your yard pimp? Or we can do shrimp.
Well, I might have to sit this one out but I did make a Monster installation video with all the details ua-cam.com/video/JKcvUjD9NrU/v-deo.html
Thanks for your video but i believe you left out the no vac line set cost in your calculations. These line sets can be very expensive with 50' lines costing over $500 dollars.
GREAT VIDEO !! I probably missed it but what size home is this ? I believe you installed a 3 ton unit for this video. I have a one floor 2465sq. ft. home in Florida. I am interested in the Mr. Cool Hyperheat system for my home. I do live on the Panhandle and we do see temps in the winter drop to just below freezing a couple times during the winter. Would you recommend the Hyperheat system for our home?
That quote was 2x what I spent 11 yrs. ago for 2 complete systems installed including a 10 yr. transferrable parts and labor warranty (which I never used). That's a lot of inflation.
Yeah, I need to replace my HVAC unit that just died and I’m shocked how expensive it’s going to be even if I can manage to do the install myself. The only thing I’m not losing my ass on these days is my home which has gone up in value a lot since I bought in 2014
@@riffdex How did it die?
@@wholeNwon Compressor doesn’t appear to be engaging anymore. It still blows but just warm air.
@@wholeNwon it’s a 1994 unit so I don’t see how stitching it back together and continuing to repair it will be cost effective
@@riffdex Depends on what's actually wrong with it. Mine were 47 yo and still working when I replaced them.
I have a integrated condenser/air handler unit outside my house. There’s no room to put an AHU inside. All the ductwork already exists for my central system but my AC unit died and I wanna replace it with an integrated unit. Is it possible for me to hook up a new central unit out there without having to install refrigerant lines (I’ve no experience with this). My impression is that I just would need to buy the correct sized HVAC unit, connect it to the intake and the output ductwork, and connect it to the electrical that already exists outside there. There’s already a concrete pad
Wow. I've never seen, let alone shopped for, a heat pump. I had my forced-air gas furnace and a/c replaced for less than $6k two years ago. Electric must be a lot more expensive.
Dang, $6K would be a smoking price in my area 👍
I bet around 10k depending on what the kind of system, how big, etc
Looks good. Do they have a horizontal unit for crawl space installation.
That one can be installed horizontal 👍
This was interesting. We are looking at heat pumps for mini splits in Minnesota, but unfortunately this unit (which is their coldest temp unit from what I can tell) only operates down to 5F (-15C). We need at least down to -15F (-26F) for code here, and even then, we'd still have a backup baseboard as the performance drops off. (Baseboard is super expensive, but we'd only need it a few weeks each year.)
These units can also have supplemental heat coils installed to help drop the low ambient capability. I will be doing some testing this winter and sharing the results. I am just a bit south of Chicago so I won't get as cold as you guys be we usually get a week or 2 of temps with 0F or below zero for lows.
Look into a Mitsubishi or Fujitsu, much better units and they go lower. Also that auxiliary heat coil he is referring to will cost you an arm and a leg to run if the heat pump can't keep up
I fantasize about replacing my entire HVAC system with mini-split room specific setups.
It's only 1400-ish sq.ft. but everybody i knew said "don't get heat pumps." So we got an electric-gas ac and furnace four years ago.
Now everybody wants a heat pump.
I will always have gas appliances, and furnace/ water heater. No way am I going all electric, significantly more in energy costs annually. Sorry Big Joe......
@@natersalad889I hear ya. It's my way of trying to minimize giving PG&E money... especially if our solar keeps up.
Maybe make my kid generate some supplemental using a bike...
Wow. Fantastic.
Can anyone help me out, with my question about hooking a Nest (gen 3) thermostat to a MrCool 36k hyper heat system. Thank you for any help you can give.
Great channel!
Thanks Jack 👍
thanks
Very nice video. What is your fee?
Where did you find a brake to bend and create the plenum? You went over that in about ten seconds and did not provide details. You said it took 12 hours and was a big cost.
Yeah, that was a big part of the job. I am releasing this video to the channel today which goes over the entire process for the installation ua-cam.com/video/JKcvUjD9NrU/v-deo.html
Bender for $25 on Amazon
@@imsimonm100 no. $1900 might get a brake big enough and strong enough to make the correct gauge plenum. How long they last is another question
The thermostat you showed they don't even sell. what a bummer! 🤨
Seems reasonable. Not sure if the travel time to and from the home store is included or not as well as the time to shop for and purchase the needed items. Another critical aspect is the time it would take to research Hvac product selection and verify as needed. All said and done, I’m guessing total time is closer to 60-80 hours. At that rate, might make more sense to pay to have it installed.
Good point, travel time was included but the research time to select the unit and prep for the project was not included 👍
Thanks! I'm guessing you live pretty close to a home store as your times were pretty expeditious considering the quantity of trips required. My trips to Home Depot / Menards generally include a stop at Chipotle (or liquor store if things are not going well) so that adds an additional 30 minutes to each trip minimum. Did you evaluate heating and cooling load calculations into your component selections prior to pulling the trigger? I'm looking at a system upgrade and looking for guidance on modeling HVAC sizing requirements given some recent energy efficiency home improvements (windows and added insulation) and any possible constraints to ducting capacity. Did you run your own calculations prior to system selection? @@EverydayHomeRepairs
Man all these HVAC trade boys getting offended on here cause you installed a unit yourself. Y'all will still have plenty of business. No need to throw shade.
Any permits or inspections required?
That will depend on your area. If you are a rural property there could be no permits needed and some area even if it is your own home you might not be able to pull a permit for the electrical. Best to call your local building inspector office if you have one and get their feedback.
Excellent series
Can that unit in your opinion work in an attic
Yep, that is a pretty common application 👍
Whoever designs and builds a house with the air handler in the attic needs to see a psychiatrist.....
As long as you know how to change the evap coil position
DONT put an hvac system in the attic unless the attic is conditioned ...
LOL, especially if its NOT a conditioned attic, then they need to see 2 psychiatrists! lol@@natersalad889
Really great video. Thank you The A/C contractors will hate this..
Tony, we hated more when you call us after you or the lowest bid screws it up and then we are called in to bat clean up. We’re all for diy. But there’s a reason why doctors make what they make or a lawyer makes what he makes or a farmer makes what he makes. It called being a professional.
There is No reason why A/C supply stores will only sell to contractors with a HVAC license in today's world. Everything else in your house you can buy very easily. The time is coming soon to where they will sell to everyone with EPA Universal certification, just to stay in the game. Enjoy your extra $$ while you can. @@lovingcareheatingandair6794
Installing a hvac system should definitely be left to a professionals.
Yes but then we get to come back and make tons of money off these dyi guys when we come to fix it.
@@Matt133 lol yea i guess you're right
@@johnmflores85 let's be honest, was it vacuumed properly? Probably not. Was a torque wrench used on the flares? Probably not. Nitrogen sweep? Probably not. We know what will happen eventually. Let's just make money off these UA-cam university types

Took you 40 hrs and i could do it in 8 hr. The concrete pad would take me 45 minutes the day before so it could set up
Thanks for the feedback.
@EverydayHomeRepairs just wondering did you check static pressures? How did you decide on unit size? Is the duct work the correct sizing for this unit? How loud is the return? Does this new unit put out more cfms then the older unit? Can you adjust fan speed? I understand that you are down playing the technical side of hvac and trying to say anyone can do it but these companies are feeding off of you. Id love to see your old electric bill compared to the new one to see if it's more efficient
@phillipbanes5484 I actually am, people bitch cause what takes the average Joe 2 or 3 days can take people in the trade less then 8 hrs, but they bitch and moan when they see the cost. Cheap work ain't good, good work ain't cheap, just FYI
Really, how much are you saving when you get the 20000 dollar fine for just accepting delivery of the outdoor condensing unit. Unless you have a epa refrigerant license it is illegal to touch the linesets And not leak testing. I hope when all the 410 leaks out in a week. They charge you up to 600 dollar a pound. Hey I live off of people like this. Keep sending me business, after it all screwed up.
People like you take food off of tables of real hvac contractors
You would be surprised on how many people watch a video like this and actually decide not to do a DIY installation because of the amount of work.
people like you GOUGE people and leave them broke, and laugh all the way to the bank, so go run to mommy and cry on her shoulder! and if you dont like it, then get into another profession..
To be honest it looks terrible
better then some of the so called 'PRO'S'
I fail to see how this could be done well without a professional doing it. No offense I'm sure you are a smart guy, but there is a reason we have licenses to do this stuff. And no credible HVAC company is going to touch this of it was installed by a homeowner and breaks down
i fail to see why your so stubborn! your rant really doesnt have much worth!
How hard would it be to install if you have a crawl space?
