I’ve tried figuring out how an AC works and have watched 5 videos before this one. This was the only one that could actually explain it in ways I could understand lol.
Awesome! We are so glad to help people understand the workings of hvac systems? Let us know if you have any other questions regarding AC Repair or AC Installation and we will do our best to provide answers. Thanks!
Same
im studying HVAC and having a little difficulty grasping some things. but the lines "there is no such thing as 'cold'. its just "energy or no energy", and the one about "you cannot destroy energy. only change its form" really helped. it was like an Aha moment
*Love this unit! Using upstairs in my sons bedroom **Fastly.Cool** and he’s finally able to be comfortable upstairs without me freezing downstairs. Works for more sqft than expected!*
Best explanation, when you can explain something in simple terms it shows mastery of the subject..unlike other videos where they try to make air conditioning a rocket science.
This was very well put together. I am glad I took the time to watch this video. The narrator was spot on in explaining
why does it take a brand I never heard of to explain to me in detail but simple enough language for me to understand with thermal dynamics.
Lol, all other brands are making it to complicated to make $$?
Its the law of youtube
Why did I take thermodynamics as part of my mechanical engineering major in college, yet I don’t recall ever being taught how air conditioning actually works. Sure would’ve been a great real-world example of thermodynamics and heat transfer classes.
Thank you this is going to be my career choice I am currently 13 and I need to know everything I can
what kind of 13 yr old wants to be an A/C tech
Nimble Films hvacr is the way to go👍. Your job will never move overseas like a bunch of other jobs. You'll be set for life.
@@xSOLOArts That's a good question.
Nimble Films great career choice. Trust me your job will not get moved over seas for cheaper labor. You will always have a good reliable job that's in high demand. Just think every house built now has ac. Godspeed
Kids gonna be a millionaire by 30
Best video on this topic in youtube. Thanks.
Was just about to type the same thing. Most of the videos are garbage. This one isn't bad.
This video explained everything perfectly. Thank you.
It’s always the old video in low quality and old animations that delivers the best of content
This was an awesome video thanks
Happy we could help. HVAC is our passion!
Best video for explaining my HVAC system. Thanks!! Awesome work!!
Great video, it helps explaining the heater first, and then the full VAC.
Of course the best explanation on HVAC comes via an outfit from TUCSON ARIZONA
Finally a non overcomplicated educational video for dummies!
OMG, best video ever. So clear and easy to grasp. Thanks!
Thank you for a video I can actually wrap my head around.
Im qualified now!
This narrator speaks very knowledgeable and fluent.
Is it helpful to place a canopy cover over the A/C unit so it is shaded from the direct sun light?
BEST EXPLANATION
Just got mind warped... Got it tho. Very informative! And I was just curious!
great explain, my parents' house has a hybrid system. That is, a gas heater carries hot water to the AHU and that's how they get their heating. The problem is, no hot water = no heating for the house. We're almost 3 weeks without a working water heater and the average temps have been in the 30s at night.
Outstanding illustration and explanation. Thank you
Finally, a great explanation. Good job!!
Great animation!
awesome!
Thank you. Finally understand how heat pumps work.
Omfg thank you. I been working at a ac factory putting them together and it peaked my curiosity and how exactly it works and now I know
what happened for the expansion valve, its one of the main components in AC system
Couldn't have been better.
Thank you for the explanation! 👍🏽👍🏽
Nice, short, and simple. Thank u
Great vid. The only thing missing is how the cooled liquid in the condenser unit is converted into a cold gas. I assume an expander, like a fridge?
Yes there is either a thermostatic or electronic expansion valve in front of the evaporative coil. I wanted to keep the video simple so that the average consumer could understand without getting overwhelmed or confused.
I live in Tucson AZ!
My only question is this: An AC system has a finite amount of refrigerant, and there's no way the exterior heat exhaustion can remove ALL of the energy from the air (cool the refrigerant back to the temperature it was at when it was in the Evap coil), so what keeps the refrigerant from getting warmer and warmer as the system continues to run?
Also, let's say that the outside temp on a hot day is 98 degrees F. If the system has been on for a while and the interior air temp in the home is now a comfy 75 degrees F, how does the air not get *_warmer_* as it passes through the heat exhaustion?
When the refrigerant comes back into the evaporative coil it goes through a device called a thermostatic expansion valve which drops the pressure AMD expands the refrigerant there by dropping the temperature. Temperature and pressure have an intimate relationship when you raise or lower one the other one does the same. It is then able to absorb the heat from the air in the house even if it is only 75°. Then when the refrigerant goes back to the outside unit it is compressed to raise the temperature up in the 220° range so that when you’re pulling 98° outside air over it you are exhausting the heat outside. Once the heat is exhausting outside the refrigerant is condensed and is ready to go back to the evaporative coil inside
Thank you@@Idesignac
Your flow "directions" on the refrigerant loop are actually backwards. Cold vapor enter the compressor, its compressed into superheated gas, run thru coil to become a "warm" liquid that goes back to evap coil.
awesome, simple video. i finally understand this, thanks!
Great video !!! Really helped me understand how ac works !

The condenser and the metering device (thermostatic expansion device) are missing.
Faltou falar do condensador e da válvula termostática.
You should have a valve or a orficce it is one of the monst important parts of an A/C
Thank you for a video that actually makes sense and easy to understand.
Good video. Pl always mention the unit of temperature. In many countries its Centigrade and people get confused.
Great video!!! For this type of unit, would you recommend for the AC unit to be off or on when the outside air is filled with smoke from a nearby fire?
turn it off it could fry itself
Its still hard for me to grasp how this process in the condenser is sufficient to cool it back down that much, and not just down to an ambient temperature. I thought it involved a process where the liquid in an enclosed system is suddenly decompressed, thus letting out heat into the new space.
my gas burner is on when my ac is on; do i need to turn it off? also sometime my ac unit doesn't have air flow. thank so much if you can help me
One moment in watching a video how space time works but my ac was going went to shut it off and I was like how the hell does this blow cold air😂😂
great video, I really enjoyed the visuals and simple explanations! thanks
So helpful, very well explained! Thanks!
Best video
Two problems I keep having.
#1 once the desired temperature is achieved, it stays on. This in 100° days my filter just changed is getting dirty quickly. Some teens threw dirt in people's ac fan units outside.
I could smell the maintenance employee smoking. So if air is circulated from inside then how is my filter getting dirty so quick?
#2 if the coils outside around the side did get dirt clumps dumped into the fan, what would that do?
I read that the cost to install central air conditioning, including the unit, ranges from around $3,000 to over $7,000 on average
but as a HVAC contractor how much do you charge for the work you do?
This is so fascinating tbh
Good explanation ...
Great video, very informative.
What is the name of the track in the background?
Condenser unit
I’m an engineer but I still can’t wrap my head around how the compressor unit aids in the removal of the heat. After compressing the refrigerant solution (which is a gas), doesn’t compressing it make it even hotter? If so, how does the cooling fan help bring it back to stable temperature so that it acts as a coolant again? Not sure if I buy the idea that the fan alone removes enough heat so that the solution becomes liquid again.
What is the blue colour in the condenser?
just amazing, loved the explanation
So given the choice, do I put the AC unit on the garage roof with a short cable run and higher summer roof temperature. Or, in a shaded ground level area, but longer cable run?
i have but one question that no amount of research/videos are answering: does a typical split system on a typical development home in california (ex. 2000-2500 sqft), draw outside air into the summer for cooling? if so, does it do so on the hidden back side of the furnace that nobody can see or reach? there must be some % fresh air in the equation and i'm curious what percentage and how/where it is done. one comment notes that most new homes have a HRV or ERV (energy or heat 'return ventilation') system, but how do they work and why is 'outside air' omitted from all videos?
Outside air or a fresh air intake is typically cut into the return to pull in and mix outside air with the conditioned inside air. This is only required if the house is sealed at a certain level of tightness. Most new homes have a fresh air intake and all commercial applications should have one.
Thanks
what keeps the evaporative coil from working when it's cold outside and you want warm air in the house?
Great video
helpful video thanks
Question: How does a home AC system ventilates and get rid of carbon dioxide that we exhale and fresh O2 gets pump inside the home? I don’t see an air exchanger in my home?
Sooo helpful ! 😄😄😄😄
how much Freon does an air conditioner cycle every hour? like if someone were to [metaphorically] pump Freon strait through it into an empty swiming pool. would it overflow it or just barely fill it
No OUTSIDE ( fresher air) intake into the system?
Inside air would be very polluted from offgassing of chemicals from furniture, carpet, cleaning products, perfumes, cooking?
Faz A No cooling/heating outside air would be less efficient since most likely the outside air is going to be hotter or colder than the inside air. It's easier to change the inside air a few degrees than bring in outside air and Change it 10 20 or even more degrees
open ur windows
Most new houses and even older houses are suppose to have a fresh air intake that runs into your return duct generally 10 feet away from your Blower motor. If you have a furnace set up in your basement, generally cool air will follow into the fresh air, as cool air falls and hot air rises.
The compressor actually is drawing in a low pressure super heated cooled vapor not a hot gas.
Of course its the small companies that do the big brain work
magic till now
Great video.
none of this would work without a flow limiter (tiny orifice through which high pressure liquid passes and EXPANDS TO COOL)...but that most important thing was left out
Whalen I touch the liquid line when the compressor is running it fells warm
Nice
Is it accurate to say that A/C systems require electricity to run and that energy is transformed into thermal and sonic energy? If this is the case, would an A/C unit displace more thermal energy than it is removing from the air inside the house?
This isn't fusion kid, the point of luxuries like AC is to be comfortable, not to process energy from the atom effeciently.
Man this heatwave in Washington is no joke
You didn't mention the thermostat or the electrical system of the unit so this video is incomplete. Nonetheless, this is a pretty good video of the portion covered.
AC units from where I am run off 240 volts from the breaker panel and generally require anywhere from a 15-40 amp breaker depending on the tonnage of the unit and design. High voltage wire will run from the breaker to outside your house and into a service disconnect box that runs into the unit to power it. A communication wire of 24 volts, 2 wires will run from the condenser to your furnace board in the terminals of Y (for cooling) and C or common, which is continuous power. There you connect your Y from the thermostat to Y on the furnace board. When cooling is set on the thermostat it will send power to Y and G I believe, and then it will energize and close the relay (switch) and communicate through the 2 wires from your condenser turning it on. In some scenarios, some thermostats will energize Y from the feedback of the G Wire (fan) when you only activate the fan and or ventilation fan. In this scenario you would have to put in a relay to stop the back feed.
On older furnaces that don't have a board, you have to build a Y pack, at least that's what we call it here.
How does it know when to turn on and off when you set it to "AUTO"?
Example: I set it to 75°F on cool and when the house gets hotter it turns on then back off when the house is 75°F again.

Probably a thermometer inside the house

Thanks m8
I want to know the price
Ahhh 2019 with smartphones... I have a question, I google or youtube, I get answers 😁
If somebody invented a portable product that blows cold air in a way like hair drier blows hot air, they’d be a multimillionaire. But portable AC can’t exist without the heat being released outdoors
this video is confusing me more... great for people who have more theory on this topic
Strange how come there is no metering device in your System (Orifice, TXV) ??
We are tying not to make thing too complex for people just wanting to understand the basics.
Wouldn't you be breathing same air over and over again? What if your basement door is closed? Where will air come from? So we are breathing Carbon monoxide basically???
Most new homes come with a HRV (Heat Recovery Ventilation) or ERV (Energy Recovery Ventilation) system. It’s their job to bring in fresh air from outside, regulate its temperature to match indoor temperature, and distribute it through the hvac system. Also, all furnaces exhaust their waste gases outside, so you wouldn’t be breathing in CO or other hydrocarbons.
No home is hermetically sealed. I’ll homes Leak some of the air. If the home is sealed very tightly like new homes are they are required to have a fresh air intake so that the system is mixing some outside air with the recycled inside here.
almost like they are building them tighter and tighter, almost like a tightly built home NEEDS AC@@Idesignac
The condensed refrigerant is too hot to absorb heat it must go through a TXV.
I am impressed by the contents that were put in this video. Love the way, basics of refrigeration cycle explained in this video.

help me! i cant get no help from my electricians they think i'm stupid an what i want to do is just dumb....... i am a cryptocurrency miner an mining take a lot of juice aka electric as well as a bunch of computers and all i asked them is it there was a PDU that i can get to plug in to my oven outlet so that i can run multiple computers i have a toaster oven so no need for an oven . so i will ask you can i get a PDU for my outlet is so can you share the link . what kind of plug should it have in order to do so . thanks for you help
Boil at 40 degrees? is that F or C?
zombiesurfer1 Nn
zombiesurfer1 F
The video overall is interesting, but you really have to keep track of expressing yourself correctly.
"The refrigerant is so cold, it boils at only 40º", for example, makes absolutely no sense. The boiling temperature is a property of the compound, while the temperature is a state variable.
Depressed Robot
I think it kinda make sense.. Bcoz if it boils at a low degree that means its natural form (the un-boiling one) its temperature is so low >>> cold.. Correct me if im wrong
Carboturbulant. Minus zero salt sugar. remove 2210. and 6 plus five. Now just enter your temp. and weeee zeeee. Alaska
makes sense enough to me, isn't wrong. in relation to us the refrigerant is cold "so cold, it boils at..."
this video is made for the average dumbass so that it makes sense to them. Your understanding of thermodynamics is beyond the scope of this video so why are you watching it in the first place?
Yep, ice boil the moment you piss on top of it
AC went out in my home.. had to figure out how it works
Hopefully our how ac works video helped.
I know
No hot or cold = Energy or no energy? When it comes to feeling temperature with our bodies, Don’t you mean that it’s the transfer of energy?
You forgot to mention the expansion valve in the AC unit
Beating about the bush.
"Thermaldynamics"
1:41 was that just cannabis
Why are gonna explain heating first? I looked up how a/c works
Woosh
This video is wrong... When the compressor compresses the refrigerant, the pressure of the refrigerant rises which increases the temperature of the refrigerant. This is because of Gay-Lussac's Law. Basically if the pressure goes up, the temperature goes up. If the pressure goes down the temperature goes down. So the refrigerant was pressurized which means the temperature goes up (gets hot). This happens with the compressor. The condenser is just there to take some of the heat (lower the temperature) away from the refrigerant. The condenser does not cool down the refrigerant that much. The refrigerant is still under immense pressure and is very hot. When the hot, compressed refrigerant gets to the evaporator coil in the house, the pressure drops (the pipe gets bigger in the evaporator) and because of Gay-Lussac's Law, the temperature also drops. Thus the evaporator coil becomes cold because the refrigerant is now under far less pressure (and temperature).
