How To Install Your Own Central Air Ducted System | Mr Cool

[@petermichaelw]

Dude, first time watching your videos and I'm very appreciative of your product here. You are explaining essentials without going down rabbit holes or blathering on with personal stories. You are putting the camera in the right place. I'm beyond impressed, Sir. A DIY video king here, folks. RESPECT.

[@EverydayHomeRepairs]

Thanks buddy 👍

[@b-gill9224]

You have inspired me to do install this system in my 70 year old home. Aweseom video.

[@leehuff5045]

Omg, best start to finish video on MrCool . Had trouble understanding the wiring. Now i know.

[@noway1596]

Your videos are easy to follow and very informative. We just installed a Universal 4-5 ton Mr. Cool in a remodel for my son and daughter in law. Big help! Thanks.

[@tomg4753]

I have just ordered the same system. Was the air handler A- coil pre charged like the line set?

[@ricardomg1991]

What a great channel, I usually don't leave any comments but man you did a great job and excellent explanation thank you

[@utubepro7742]

I do hvac and I must say GREAT JOB !

[@utubepro7742]

This guy make professional hvac guys look bad😊

[@netsplit64]

Doing an install of the 4 ton version of this system. One thing I learned is finding terminal rings that fit the narrow tight terminals is tricky. What I eventually figured out is I could use a hammer and a concrete slap to make them oval terminals which fit!

[@jkia9998]

15 years ago our hvac company built custom boxes out of plywood for the return air to enter and for the air handler to set on. Maybe cheaper than buying a kit online. Also don’t forget a good sheet metal contractor will make the box for you as well.

[@mrsayao]

Great video! I've watched a few DIY HVAC videos in preparation for tackling my own job. One thing you should do once the box/ducting is all done is use the sealing paste/glue on the inside of the joints and then tape the outer joints where you can't put paste.

[@RC-Heli835]

You did a really good job on this sir! Thanks for sharing! You sound like Mike Festiva talking. He's a youtuber who built his on Mule to run around the property, articulating dump truck to move dirt on his property and a saw mill to saw wood from the property. And on and on it goes!

[@jpenn727]

Wow, what a great video you just dropped. I'm sure it will help a lot of people in the months to come. I would suggest that you seal the ductwork you fabricated. Something like ShurTape 686 metal on metal tape would work. This will do a great job of closing all those openings and will provide cooler air to the home and you won't be sucking warm air into the conditioned supplies. I would have added a condensate float switch as an emergency cut-off when the condensate line stops flowing. You should have also added a high-quality surge protector to the outside unit. These units are run on sophisticated computer control boards and are sensitive to electrical fluctuations. I've been a fan of the Ditek Kool Gaurd 2, but most other brands will help protect your investment.

[@murky2502]

It's probably already noted, but I'm not going to read 200 comments to see. Shouldn't you use a 2nd tool when torqueing down the cutoff valves at 49 minutes? You were putting some pretty good twist on those fittings.

[@harblindersingh3781]

Thank you very much for the video. We were able to successfully install our Mr Cooler Heat Pump. Great Job, keep it up.

[@richlikeg3722]

You can also put some refrigeration technology nylog on the flares for extra protection against leaks.

[@mikestillwell5566]

What flares?? There aren't any flares.

[@louismarquez1847]

ACIQ also has the very same system with hyper heat and the same size. I just finished installing mine and shes a beauty very quiet and cools plenty and heats very quickly.

[@EverydayHomeRepairs]

I have been super impressed with how quiet these units are, very nice 👍

[@Kamikazekyle05]

How has the unit been working for you so far?

[@emiller7040]

Nice job. Looking forward to seeing how well it heats without heat strips.

[@EverydayHomeRepairs]

Me too 👍

[@chasewichert4490]

@@EverydayHomeRepairs Did you ever figure out how well the heat pump works?

[@ARepublicIfYouCanKeepIt]

I replaced the original 20+ year old central A/C system at my mother's house with a Mr. Cool Universal series unit. The entire experience was great, however, I did opt to cut the precharged lines in order to have a cleaner installation without unsightly loops of excess line. Again, every installation of this type is custom. This was just my preference. A fast and affordable service call to vacuum and recharge the lines was all that was necessary. (Note that I had this done *before* opening the valves on both units. That way only a minimal amount of refrigerant was needed.) I mounted the exterior unit on the wall, rather than the ground in order to keep the unit cleaner. The only criticism I have for the Mr. Cool units is the line set insulation. This quickly broke down in Central Florida. All-in, the replacement cost me ~$3,500 (less than half of the lowest bid from an HVAC contractor). The unit is whisper quiet and consumes half of the electricity of the original unit. Lastly, this unit has no problems both cooling and heating my mom's home (no resistance heating strips installed).

[@swss12]

Great video. For 240 circuits using romex you should be using the red sheathing version which provides black and red conductor insulation.

[@michaels840]

I've used the 3M silver tape (3350) to get a tight seal on my duct work. No air leaks nor whistling.

[@robinjeffery4389]

Excellent video!!! Thank you!!! How noisy would you say the Air Handler is?

[@EverydayHomeRepairs]

You bet, actually it is pretty quiet. Pretty impressive.

[@pettybird]

I laughed at the genius of using the dolly to stand it up. I was trying to figure out how to do that myself

[@jimmyroberts7006]

How do you connect the condensat drain? Does that plug screw out and you need a 3/4" male pvc threaded connector?

[@ztd0501]

When I did mine I used mastic and tape on the insides and outside. I tried to minimize loss as much as possible. I even insulated all sheet metal.

[@ericelfner]

Absolutely incredible!

[@EverydayHomeRepairs]

Thanks Eric, hope this helps with your install 👍

[@acostaae90]

Whats the difference between the mr. Cool universal vs the hyperheat central. Are both capable of nest thermostats or any wifi thermostats?

[@gameondude3617]

I would recommend some aluminum tape around all the joints to help with air loss

[@tomg4753]

Was the A coil also pre charged along with the line set?

[@mikehaare1322]

I am also replacing my oil burner furnace in Illinois with a heat pump, I am going to use an ACiQ hyper heat, who I believe is who Mr Cool was/is using for their hyper heats. What BTU of an oil burner did you replace with this?

[@shawnphibbs4380]

Doesn’t get more gangster than that!

[@Myneighborhoodsolution]

Is this unit able to be changed from 3 ton to two ton with the dip switches?

[@TheWhiteNinoBrown]

But how do you open the overflow drain to install the line??

[@jeffreyeaton5214]

Went with the MrCool Signature series when my A/C system failed 4 years ago. Been incredibly easy to work with, great quality, was significantly better than the ole Trane setup we pulled out beforehand(Albeit, can't say it's apples to apples because the old system was ancient, plus the ductwork was very undersized. I replaced everything to be new - ductwork, air handler, condenser) I'd say it's definitely harder than using MrCool's precharged linesets because I had to do all that part w/ the gauges, scales etc - significantly more costly, but it all still worked out and works great

[@bert1913]

On the return plenum, your cross breaks (creases) should be installed toward towards the center of your plenum

[@80kenuel]

Great video, the only issue I see was that the unit doesn’t have a heat strip. You need it as a back up just in case the unit fails with a leak or blockage. Second what will happen when the unit is in defrost mode with no heat strip?

[@hassanbazzi3545]

That is one amazing project. Well done 👏👏👏👏

[@tonyd3029]

Great video, I love it. A/C supply houses will not sale a A/c unit without a A/C contractor license. It is a closed world there. You can buy Freon if have an EPA license. But you cannot buy equipment (A/C unit) without it. It is a lot more politics than having the proper certifications. So, this perfect! Thank you.

[@EverydayHomeRepairs]

You bet and thanks for the feedback!

[@jeffreyeaton5214]

Unfortunately, even with being EPA certified, a lot of places will refuse to sell you refrigerant without a HVAC Contractor license. I'm universally certified w/ refrigerants, spent weeks looking for a business that would sell to me w/o a HVAC license, eventually found one - but I had to order online, out of state lol.

I will need 5 ton system, how am I going to make sure that all accessories I buy match with 5 ton system? Thanks Scott.

[@ARepublicIfYouCanKeepIt]

In Florida, replacing an air conditioning system requires a permit...even for DIY installations! I didn't realize this, but found it out the hard way when my mother sold her home. We had to obtain an "after-the-fact" permit for the sale to close. The same was true for a water heater replacement. I served on submarines as a nuclear engineer and chemist, so my work easily passed, but the permitting requirement came as quite a shock as I've done similar work in several states over the years...all without reqiring permits.

[@GannDolph]

Interesting. How was the history established? I have a couple houses in Florida and have done heat pump changeouts on each. Neither contractor pulled or even mentioned permits.

3.5 ton unit will have1300-1400 CFM max air flow. Return duct lower 90 deg is too sharp of bend and too small total area that appears to be less than one sq.ft.. A lot of air turbulence created at sharp elbow along with very high air velocity over 1500 FPM. Will raise static pressure resistance.

[@EverydayHomeRepairs]

Thanks for the feedback.

[@TimElliott42]

The GE disconnect is not highly rated. Could one install the Siemens 60A disconnect for both the indoor and outdoor units?

[@user-cz8do7xl8u]

Only critique is on the plenums, you could have used S-slip for the joints (helps with the flexing). Duct butter the internal seams, the last seam and cover with insulation. The only ones who will know are the next guy who's there to replace the air handler in 25 years and will likely re-use the plenum. Great work otherwise. I've seen pro's hack in pro made duct. Great vid.

[@manish1982]

Awesome video Scott, as always. Getting ready to take on the same DIY project and everything was super informative. Only thing I really wish you did was actually go for Nest etc thermostat since the are generally tricky with these "communicating" units. Any chance you can do a separate video to try and upgrade the thermostat as you kept that 18 gauge wire for later "upgrade" project anyway?

[@EverydayHomeRepairs]

Thanks for the feedback and I will add the Nest install to the list of future videos 👍

[@ericgladden2691]

Where did you purchase that 90-degree filter rack? Thanks for this install video. Great Job!👍

[@larsdueck1226]

You'll want to use foil tape and/or mastic to seal the edges of your new duct work. You don't want air leakage on the supply or return through the gaps and cracks or in the ductwork in general. (Even perfectly cut and installed ductwork by default leaks air.)

[@EverydayHomeRepairs]

For sure, thanks for the feedback! 👍

[@aspinthereddragon9302]

how would you do this if the air handler needs to be in a attic?

[@Primo-dc8qq]

Around 4:30 minute mark, you mentioned that switching from a right to a left horizontal setup would require reconfiguring the evaporator coil...i have purchase one, and don't find it obvious how this is done...is your thinking to leave the EC in place, and only reconfigure the top drain pan to the bottom (somehow), or actually removing the who coil, flipping it, and exiting the drain lines on the opposite side of where the access panel/lcd screen exists (and obviously then drilling new holes into the back-side sheet metal)? I couldn't come across another video on this, so if you did, could you share? thank you, and very informative video (and subscription).

[@voookal]

I have the versapro and had to remove the whole coil and rotate it 180. Also I had to take out the " inside heat sensors" I believe it's called, and tie it to the top

[@diymco2728]

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)?

[@EverydayHomeRepairs]

For this one most states are municipalities would require and electrical permit and inspection. Since this system is all electric the gas lines would not be part of the installation.

Okay, so I live in an area that 3-4 weeks a year the LOWs can be between -20F to 10F, which for these kind of heat pumps is not a high efficiency range, and so other brands I know of have supplemental coils that HEAT when the heat pump itself can't do so, do you know if Mr. Cool has equipment with this functionality?

Why did you pick this one over the Universal? Was this because of a sponsorship? Comparing the specs, the universal is more efficient and they both go the same low outside temps. The Hyper Heat looks to have a slightly better warranty and might be slightly cheaper, but otherwise it looks like the Universal is the better option. Also, you said you weren't going to use the thicker filter option. They are definitely better: better airflow with higher MERV ratings and they last longer (I change mine once a year).

[@edwardgrier7096]

Best video for the Mr. Cool heat pump. I just purchased a Mr. Cool Universal 4-5 ton heat pump. You spoke of using a Mr. Cool thermostat. Do you have a model # for this? I looked everywhere to buy the Mr. Cool thermostat and even Mr. Cool didn't show it.

[@tdginctr]

Scott installed the Mr Cool Hyper Heat model, different from the Universal (although they are both central ducted). The Universal can use any 24 V thermostat, the Hyper Heat uses RS485 and that proprietary thermostat comes with it.

[@dalemarr70]

Good God man, SEAL all your SM joints ! You've got a giant sive there. !!!!!!

[@TexasEngineer]

Did I miss something? Did you forget to insuate your supply plentum? It will get cold and sweat and rust your sheet metal. Made that mistake when rebuilding mine and had to put duct board on the outside instead of the inside. I noticed that your exsting ducts were insuated on the inside. Your temperaure at the vent were off. For cooling there should be about a 20 degree F difference between return air and supply air. Unless you have a variable speed unit. With a variable speed unit you have to get it operating at high speed to take the measurement.

The Universal can effectively heat down to -24°F/31°C. Supplemental resistance heat strips are optional, though additional power is required.
