How to install a 4-way ceiling cassette heat pump / AC

[@BungeeRooster]

It's very nice to see your kids helping out. Reminds me of my father making us work with him. Then again I feel bad for the kids because it reminds me of my father making us work with him.

[@CategoricalImperative]

Lmao. I have similar ‘mixed’ feelings of helping my father. But I have a lot of experience working with my hands and repairing things now.

[@eyygurke6081]

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.

Nicely done! I love the completely inappropriate music... it's all like, "It's a wonderful spring day and I'm happy to be alive and the tasks before me are being executed smoothly and with competence because I've tried to live my life with grace and fairness." Now if *I* had been installing the same unit the soundtrack playing in my mind would have been death-metal of some sort because it would have been one long series of travails. But seriously, this was nice (and informative) to watch. Thanks for posting it.

[@2LegitTooQuit]

@20:19 for anyone wondering there is a bare ground being connected as well that he forgot to mention with the 12/2 wire.

[@eschrader]

5:30 the good thing about installing a home AC, everyone is willing to help!

[@MichaelHernandez-lc2wb]

Spotless work, amazing details and kids helping too, bravo!

[@heididecker707]

I would have you work on my home in an instant! You are so thorough.

[@techguy2342]

Crows foot should be at 90 degrees for proper torque. Evacuating should also be done using a micron gauge as the gauge set doesn’t have enough resolution. Otherwise, nice job!

[@PayNoTaxes0GetNoVote]

Yeah, I caught that too. Thought maybe he accounted for that by doing a rough adjustment in the torque settings. I was hoping to see if the Senville Cassettes had the knock out like the LG's do. I need to steal a little bit of the supply to condition a small bathroom. The Senville units are significantly cheaper than LG and have better low temperature (heating) performance, -13F vs -4F, if the numbers are to be trusted. Do you happen to know if the Senvilles have that option?

[@degenhexican9355]

Love the video and as a mechanic myself love your techniques A+

[@dffps129]

nice job. I think code requires braided copper for 220v whip.

[@erikkovacs3097]

NM cable is not designed to be run in conduit. You can do it for short straight runs but it gets very difficult very quick. It's just easier and cheaper to run THHN.

[@Rambleon444]

Can you strip the outer sheath off and then run it through the outside conduit?

[@786otto]

Nice video, whole family is helping.

[@David-jq9oy]

Thanks for making the video! I never thought of using a crows foot on a torque wrench to get in tight spaces. Also, I hope you get a new chisel for your birthday. :)

[@joeltell8484]

what a perfect installation

[@iamdenislara]

14:27 question: those systems don’t require purging. So why did you?

[@BridgerScientific]

The system would benefit in longevity from purging with dry nitrogen. And he should also have done a pressure check at ~ 400 psi with dry nitrogen before pulling the vacuum. And as others have said, he should have used a micron gage on the vacuum test to insure good sealing all around. The difference will be, does he get 12 to 15 years out of the system, or less? When the moisture separator/filter is all used up from taking contaminants out of the system, or the refrigerant leaks out to a certain extent, service will be required. He is no doubt saving $ doing it himself, and bonding with his family. So worth the risk I would assume.

[@cm0ly989]

Excellent job on both the installation and the video!! Thank you!

[@abaddadproduction8112]

Thank you! Well done!

[@grapeabyss1744]

No sub 500 micron vacuum? No nitro pressure test?

[@Northwest736]

Thank you for this!

[@peterhoward2113]

Hi, I just want to say thanks for this great video! I'm currently installing the same one. do you know what that extra wire in the indoor unit that you left disconnected is for?

[@jasonclare1481]

Great video!!!

[@blmdh20s]

Why would you purposely introduce contaminants into the system with the thread seal when attaching the liquid and vapor lines? How long did this unit run until it failed?

[@mikekellum6238]

It shows the installer has no idea how a flare fitting works. The threads do not prevent leaks. The threads provide the torque to which forces the flare surface to mate with the connection surface. Thread seal is not needed and as you correctly pointed out, contaminates the system.

[@gazd4812]

@@mikekellum6238 does the copper pipe (flare fitting) deform at the point of contact, when its tightened ?

[@mikekellum6238]

@@gazd4812 No. The flare, when properly made simply mates with the surface of the connection. The threaded nut, simply apples the torque required to keep the flare faces tight against each other. This creates the leak free seal. Threads are NOT used to seal .

[@Ivebeenaroundyouknow]

I was physically cringing watching him apply sealant, especially over flare tip openings. Otherwise it was a very thoughtful install.

[@jankensmith7935]

Nice video. I was a little puzzled by the thread seal as well, but certainly appreciate the video. Masks were most likely for fiberglass and dust not a virus....lol

[@babaolowo35]

How well does this unit heat for you?

[@NoorRefrigerationsystem]

Wow Amazing video I love This channel ❤️❤️❤️

[@mannyvelez4437]

[@MysticSephiroth]

If I wanted to add refrigerant to the unit, which valve do I use to do? I have a 5 zone

[@DaveJiu]

After the installation, I recommand to only add refrigerant while cooling using the gaz line(the bigger one)

[@Littleshotphotos]

Nice work, shows what will need to be done. Can I ask where you found the no woman, no cry piano at the very beginning to 3:00 min?

[@pete134]

Nice video, but it looks like you are using a crow's foot on a torque wrench. The crow's foot should be at a 90 degree angle to the wrench, your 26 pounds is now more.

Apparently my brand New 36,000btu unit Compressor motherboard is bad???

[@calebjensen6664]

Hell ya!!

[@Elder650]

Are you sure just 12000 btu or 1 ton is enough for 400+ sq feet area 😳. Is it for cooling also or only for heating? Cuz in India every brand suggested me 4 ton or 2-2 ton 2 units at least for a 500+ sq feet area with 10 feet ceiling ht so I got 2 units of 24000 btu (27K max at powerful mode) so in total I’ve 54000 btu at max for cooling only. Pls reply.

[@HereWe_GoAgain]

My 2500 sq ft house has 2 2ton units (24000 btu), one for upstairs and one for downstairs. I am not sure of your complete sq ft but 54000 may be overkill.

[@Elder650]

@@HereWe_GoAgain Do you guys run aircons all the time cuz like if the temp remain low and constant for all the time then even a smaller unit could just maintain. I use them for 10-12 hrs in day time as it’s a living room and there are 2 2 ton units for a 500sq feet living room and it takes almost half an hour to reach at 25°C when outside temp ranging from 35-45°c in my area and these ACs are the best of the market for cooling power. I think you’ll not believe we have 18000 btu or 1.5 ton units in each of 3 bedroom and most people have such configuration here in my county.

[@HereWe_GoAgain]

@@Elder650 I went back to look at my data from last summer, in the month of august in southern US where I live (humid and hot) My upstairs unit ran for 140 hrs when maintaining a temp of 24°C. Temps outside were 36°C, when factoring humidity it's real feel around 40/42. I run my units about 7 months out of the year but I'm not in a climate like you are. It's just amazing you would require so much cooling capacity for a small space, hows the insulation in your house?

[@Elder650]

@@HereWe_GoAgain it’s a blessing to have climate like your place cuz the utility bill for elec consumption is a huge pain when running almost 100,000 btu ACs. My house is actually a villa type it’s surrounded by medium height trees and it’s a pretty old house but old houses in India actually have better insulation cuz of walls as thick as 18” made up of bricks and concrete and we also have good blinds and curtains to avoid direct sunlight so I would say we’ve above average insulation compared to others here. But the climate is kinda tropical temps could go high like 45-46° easily with humidity above 60% almost whole summer season.

[@mintheman7]

It’s highly dependent on the climate and construction/insulation level of the house. For example, passive standards require a building to use no more than 15kwh/sq meter for heating or cooling per year. You can literally heat the whole house with just a hair dryer

[@euskadi46]

What refrigerant it uses?

[@BridgerScientific]

R410A is most common for Senville units in the USA circa 2022

[@inhocsigno9151]

At 11:36 you forgot to wipe your fingers on your pants. Nice video and install.

[@MatthewsFabrication]

Mine is installed but won't do anything. Just beeps & lights come on, but louvers won't move or close when turned off. Any tips?

[@BridgerScientific]

check the power cable wiring between the outdoor compressor and the indoor wall or ceiling air handler. Communication occurs on these lines and if no comm, no work.

[@davidcoleman6995]

wrong size crows foot on the torque wrench....may provide improper torque.

[@degenhexican9355]

Using a crows foot on a torque wrench will give improper torque.

[@marsluna2127]

@@degenhexican9355 You can use a crows foot! The crow foot gives correct torque when it is at 90deg to the torque wrench. Otherwise, one needs to do some calculations based on chosen angle and length of the foot.

Your BTU calculation isn't 100% correct. You take the cubic footage of the space X temperature change X 0.133

[@marcoeis6598]

Can you post an example so I can better understand ? This is the first time I've seen someone use volume which in my opinion is the correct method when dealing with air

[@marcoeis6598]

I think I figured it out, let me know if I'm wrong. Multiply total volume by temp change. So if it's 30 outside and I want 70 inside that would be 40, is that what you mean ? ...and then multiply that answer by .133 . These numbers seem to make sense
