Licensed HVAC engineer here, if the humidity is low outside then using the fresh air vent function instead of the recirculate function will dehumidify just fine without a/c. And yes, turning off the a/c saves gas. I have heard that running the a/c periodically in the winter will help keep seals lubricated. Good to know it won’t hurt the system. Love the channel, just wanted to share another perspective on this one. Thank you
Agree, the refrigerant gas is oily, it will lubricant the seals as it is circulated thus reducing the risk of the rubber seals drying, cracking and leaking . I run the Ac at least every few weeks in the winter, my last toyota which was over 20 years old when i sold it , had never needed the AC recharging and was blowing ice cold Air, the new owner still tells me it runs perfect till now(it was made in Japan).
I totally agree. It makes me mad that my Toyota turns the AC compressor on when it’s 60° outside. I know when I need to use it when the windows fog up but I don’t need it when it’s 55° outside. All that does is put time on the compressor which I’m not interested in replacing sooner than needed. I also can’t stand in the recirculation button automatically gets selected. I know when I want to use the recirc and I know when I don’t want to use it. I wish I could just disable it. These are some of these automatic features I can’t stand
@@condor5635 "time on the compressor": forget that notion; you will cause more damage from leaking seals long before the compressor wears out from overuse.
I just told my neighbor last week that she should run the AC during the winter (upstate NY) when the temp gets above 40 in order to keeps the seals from drying out. I never gave a thought about humidity or running it below 40. Good to know it won't freeze below 40. Always good info from you. When I run my AC in the summer, it hardly affects my mileage at all in my Gen 3 Prius. Much better than the older cars.
I bought a used 2012 Rav4 last year.The vehicle it replaced was 27 years old.I saw when I set the climate control,the AC light alway"s came on in the winter.I used to turn it off but I"ve learned how it works now.Best ride I ever owned! V6,fast & fun!
I TOTALLY AGREE. Ran my air on my 97 Camry & had 0 problems, NEVER serviced it. I do it on my 19 Prius & always will. I was always taught refrigerant lubricates rubber parts. I try & do when its not sub zero temps. Plus in winter, u step in snow, ur shoes are wet/carpet gets wet MORE steaming up windows.😉
I was told years ago to use the AC to defrost the windshield on cold damp days, and I found it works better than the heat, and as a plus, you don't have to wait for the car to warm all the way up, as the AC will blow cool dry air almost instantly. I also have come to understand that running the AC several times during the cool months helps keep the system working, vs leaving it sit idle and unused for over 9 months out of the year. Then I discovered that on my Ford Escape, every time I turn my heat/AC dial to windshield defrost, the AC runs whether I turn the heat setting to hot or cold, and this was done to be sure the AC system runs periodically all year long. My truck is now over 18 years old, and while I think the AC has lost a bit of its charge, it still works very well having had not maintenance all these years.
I turn it on occasionally because I heard somewhere you should do this. With gas prices like they are I cleaned my air filter and it sure needed it so that's something folks should consider. I intend to replace it when I go to town.
I drove school buses for a living for about 10 years and I can attest to this. I would use the A/C during the winter to dehumidify the interior and worked great!!! I tried Rain-x defogger before and worked too. The only thing was that it was alcohol based and stopped using it for safety concerns.
I wish there was Mazda Guru like you. Just discovered your channel. I drove Priuses for the last 11 years, and just traded in my 2016 Prius with only 24k miles for a Mazda3 HB. I don't drive much, and worried about ruining the battery. Never had a single problem with this one or my 2012 model.
Very helpful video. I am guilty of doing exactly what you explained, I always use the automatic climate control, but in the winter and turn off the AC, because I figured there’s no point, the air is cold outside, and why put a drag on my engine, I’m trying to get the best fuel economy possible. Thanks for explaining it, I know better now.
Very valuable information. I always wondered why when I put the automatic climate control in my Camry the a/c button lights up. I was constantly turning it off. Now I know. Thanks Ahmed.
excellent point, I also heard that it lubricates the seals and minimizes refrigerant loss in the long run; I have noticed that with the direction control set to defrost or defrost/floor that will cycle the compressor as well, thank you for excellent videos and also wish many Blessings from the Lord to you and your family
I think using defrost or defrost + feet setting automatically turns on AC. At least it did in my '05 Echo. On my '22 Corolla it's much less obvious when AC turns on so I can't say for sure.
Yes I heard a long time ago use the air conditioning in the winter to keep everything lubricated and running, to add to that as well if you have a manual shift four-wheel-drive it’s also beneficial to occasionally engage that mode,conditions permitting of course. you want to avoid situations that would make it bind and such,but still don’t just let it sit in 2 Wheel Drive mode for years.
Yeah which just to let people know if your Climate control dail shows numbers instead of Red to Blue then you most likely have automatic Climate control.
Yep, great advice, as usual! I also make sure to engage my 4-high and 4-Low in my 4x4 Tundra at least once a month, especially during the summer (for 10-minutes either on a straight road or on a dirt/gravel road). What’s that old expression, “Use it or lose it!” 😎
It's good to get that AC clutch engaged, once in a while, too, and circulate some refrigerant throughout the system. The refrigerant has oil in it to lubricate the compressor and seals.
A lot of positive comments in this comments section! I encourage viewers to like his videos to help him out. I rarely ever remember to like videos, but I always remember to like TCCN videos because the high quality content and information prompts me to do so.
I've known this concept for a long time. Turning on the AC and put the setting to "warm"...you activate and maintain your AC even in the winter and rapidly defog your windshield/windows. I believe that's the best and fastest way to defog your windows. BTW...my miraculous 2005 LE with 218,000 miles...never needed the AC serviced. Now I have a 2020 LE 2.5.
My old 1995 JDM Toyota Crown Royal G had dual climate control system and it was turning on/off A/C and air re-circulation on its own. I had no reason not to trust it and all I ever needed to do is to change the inside target temperature to 24C in summer and to 20C in winter (people usually wear a lot more cloths in winter). Never had fogged up windows or any other concerns. But I was wondering why the A/C light was on when the outside temperature was dropping down to -30C? Those people who designed car AC systems did very good job!
Most new cars turn the A/C compressor on when you use the defrost setting. Hybrid cars use an all electronic compressor, which is needed since there’s no belts/pulleys and the ac needs to stay running even when the engine is off.
No mention of the lube suspended in the refrigerant? It's always been a good idea to run the A/C in the winter for that alone. Circulate the lube to keep the seals supple so they don't dry out and crack thereby losing all the refrigerant that's in a gaseous state. It also lubes the A/C compressor bearings so they don't seize up and it makes it last longer overall.
I keep it off most of the time ( with gas at $4.10/gallon in Texas I have to save as much gas as possible). But I do run it on humid mornings and in the afternoons when it’s hot or warm enough. Good to keep the oil moving through the system. I also learned from an old mechanic that it’s good to turn off the ac a little before shutting off the engine and letting the system equalize and blow the moisture from the evaporator. Supposedly it makes for a very long lasting ac system.
I think short informative videos like this will be a bigger success vs. long videos on one specific topic and vehicle that probably 90% of the people wouldn't be interested in. Although I think some still have their place
Short has its perks but long ones are the real & true gems. He’s a master mechanic who takes the exact & correct amount of time to communicate his mastery.
It depends on what you're here for. I value the detail shared in CCN channel. It's been incredibly educational for me & is not easily avaliable elsewhere. It has helped me make better decisions in car care and car purchases.
I was told back in the 1980s that running the AC continuously, with or without the heater on, prolongs its life because the seals don't dry out. I have no idea if that's true, but beginning with my 1990 Honda Accord and then my 2002 Honda CR-V, I've always left the AC on and I've never had to spend a dime on AC maintenance or repair.
Hi! I am from Canada with really harsh winter. Can you come out with tips when using a hybrid in winter? I am not sure how long I should wait before driving the hybrid car when the temperature is below freezing. Thank you for all you do! It’s great to learn from an expert like you!
To effectively use a hybrid car in a freezing Canadian winter, prioritize warming up the battery by plugging it in when parked, use the "Hold" mode to maintain battery charge, drive moderately to conserve energy, utilize seat heaters instead of full cabin heat, and ensure your car has proper winter tires with good tread, while also considering parking in a garage whenever possible to protect the battery from extreme cold. Also let your engine run for about 30 minutes ahead of time before you go anywhere which will significantly help defrost the cables. Hopefully this helps.
Living in SoCal in a LA suburb obviously our winters are mild., lowest it gets is 35 degrees on a extreme cold night for SoCal standards, never Ice or below freezing conditions unless you live in the mountain ranges of San Gabriel/San Bernardino/Idlywild or the High Desert these areas snow or below freezing in winter often, I use the AC but have the temp at 80 degrees and it dehumidifies the cabin.
Another good reason to run A/C in Winter is to keep the seals in the system lubricated with A/C oil. This is especially true for the compressor. Surprised you didn't mention that important aspect.
I thought that when u use the defrost function that it automatically uses the ac condenser for this reason? You don’t have to then turn on the ac. Is this wrong?
I use my A/C in the winter all of the time. Where I live the weather isn't that bad during the winter months. I also have an Avalon Hybrid, so gas mileage isn't a big concern. But with the current state of gas prices now, I am so glad I invested in my vehicle over 6 years ago. AMD u inform us a lot about the care and maintenance of the main battery in Hybrid vehicles, but u don't say to much about the 12v battery. Could u do a video in the future about this item. Like how long do they last, are they specialized batteries, cost and signs to look for when they start to fail. As always, love your videos and keep them coming.
@@tails300 yeah I totally get it. It works like a house refrigerator or freezer without depending upon the cars radiator [and/or] water pump to cool the freon. It's all pressurized flow I believe. All electric vehicles use this same concept. No pulleys or belts to break.
@@markypeedydj1481 a lot new plug-in hybrids and EVs use heat pumps for heating and air conditioning although they lose their effectiveness at below freezing temperatures.
👍👍Outstanding indeed! Thank you for sharing. All I learned another new and useful information. I even had my wife watch it twice. I watched it three times to make sure I didn't miss a thing. And thanks also to Ben Davis...for adding on that extra knowledge about the recirculate function. Keep up the great videos AMD. Take care and Stay Safe. JT
For decades and among all manufacturers when the defrost is selected the A/C is running, because of the blend doors is why you won't feel the cold off of the evaporator.
Good thing you made this video. I uave a 2013 toyta highlander 3.5l fwd 281k. I was using my a/c and I started hearing a hissing sound from the vents. I can reach the clutch and it spins. I'm hoping I just blew a relay, where can I find this relay and have you ever had this kind of concern before?
@@markstevens1729 This sounds more like a blend door issue. Everytime you change where you want the air to be blown like feet or face it opens and closes doors. They can be stuck and it's trying to push air through them and causes a hissing sound.
@@jamesvaldez4093 so it took me a few days to get around to checking the system and I believe you are right - so thanks! - when I bring the defrost/windshield vents into action, the hiss starts, stops when I take those vents out. Is there a way to address this?
@@markstevens1729 I figured. Unfortunately it's a big job to replace them. The entire dash has to come out and then they can be accessed. I believe there's a company called blend doors USA or something. They use to have diagrams on them.
Mr CCN...Could you make a video about the AC condensation drain tube draining onto the 4Runner frame, possibly causing a future rust problem, and how to install an AC drain extension to reroute the condensation away from the frame?
Would you do a video of transmission and motor mounts replacement, showing where to raise up the engine on a 2016 Camry, please? Do you need to raise up the engine at two different spots for transmission and motor? Thanks so much.
My Neon's all would turn the compressor on when I put the defrost on. It is good actually to run it during the winter they say, BUT it hit my mpg just like running it in the summer - at least I could tell it was kicking on and off. My Elantra does not do that and I actually like it .. even without having the deluxe defrost system they offer (it was a big concern, fortunately the "blower system" seems to function just fine .. until I go underground and the entire exterior turns to white frost .. thank goodness for heated mirrors, which I never had before and did not know how to turn them on for a couple months - I had learned to "use the Force" before that).
Hi! cVT transmission in Toyotas are reliable. I have some experience with Subaru. They’re good cars except their high performance models they’re nice but not very reliable
Subaru past 10 years could cost more to maintain and could have more issues. Rav4s are a bit more expensive and has a less sophisticated Awd system than the Subarus. Depends on your plans for how long you’re keeping it and which one you like more
@Steven Strain The only way my Nissan ac is gonna go on is if I press the ac button. That will defrost the windows. Nice thing is I can use the heat with the ac, then it's really comfortable on a rainy wintery day. The ac removes the dampness.😊☺
I saw a video were cat litter was placed in a sock and put in the car it will help with codensation. Also does it help the seals andac compressor by running the lubricating oils in the freon?
Hi again, AMD. I have a '16 Sienna with only 45K miles. Original owner. The AC was working fine. Then one day the blower is on and fine, but there's no cold air coming out. Any suggestions on where I should start checking? Hope it's not too expensive. Appreciate advice - thank you.
When my now-wife and I were dating, she picked me up after work on a warm, rainy summer evening with her heater on full blast - it was a hundred degrees in her car. I asked her what she was doing and she said she was trying to de-fog her windshield (rather unsuccessfully). I turned on her a/c and, of course, the fogged windshield immediately clear up. I told her that the a/c was a dehumidifier, she didn't understand, and the conversation proceeded down the same road millions of husbands and wives have gone down. We had a similar discussion about putting large quantities of food down the garbage disposal. She's owned at least a dozen cars and has yet to read the owner's manual for any of them.
Windows fog up because they're cold, not because the humidity is less on the outside. Air can't hold as much moisture when it's cold, and the air next to the glass is cold so the moisture condenses on the windows.
Good to know, thanks. How old are the 'older cars' that wouldn't have the modern A/C functionality? Are we talking 70's/80's cars or would a car from the early 2000's, like my 02 Corolla, be included in that category, which means its A/C might actually get damaged if it's kept on in Winter?
If I leave my climate control on AUTO in my Lexus GS 350, it will run the compressor all year round. There are times where the external temperature is cooler than my interior set temperature, and the exterior humidity is low. The compressor still runs. It just doesn't seem very efficient at times. Should I leave the climate control on full AUTO year round?
I have 2021 Toyota Camry 4 cylinder and the gas pedal is so hard and stiff to press my foot is hurting me now so bad is there anything I can do about it

Yes, as Ben Davis says, helps keep compressor seals lubricated .............
Good thing you made this video.
I uave a 2013 toyta highlander 3.5l fwd 281k. I was using my a/c and I started hearing a hissing sound from the vents.
I can reach the clutch and it spins. I'm hoping I just blew a relay, where can I find this relay and have you ever had this kind of concern before?
Like you, ‘03 Tundra, hissing from behind dash, passenger side. Got to be a/c related. Hope he answers…
@@markstevens1729 This sounds more like a blend door issue. Everytime you change where you want the air to be blown like feet or face it opens and closes doors. They can be stuck and it's trying to push air through them and causes a hissing sound.
@@jamesvaldez4093 so it took me a few days to get around to checking the system and I believe you are right - so thanks! - when I bring the defrost/windshield vents into action, the hiss starts, stops when I take those vents out. Is there a way to address this?
@@markstevens1729 I figured. Unfortunately it's a big job to replace them. The entire dash has to come out and then they can be accessed.
I believe there's a company called blend doors USA or something. They use to have diagrams on them.
As well , said to keep the seals lubricated by the oil , to prevent leaks
Yes. Thank you. Learned something new today!
Can you make a video of do’s and don’ts during winter months? And is it necessary to have a block heater? I live in ND. Thank you
Great common sense reasoning, thank you.
i run the defrost often in the winter, it runs the ac with that feature.
The windows fog because the temperature of the air next to the window is below the dew point temperature.
Mr CCN...Could you make a video about the AC condensation drain tube draining onto the 4Runner frame, possibly causing a future rust problem, and how to install an AC drain extension to reroute the condensation away from the frame?
I'm rum A/C all the time also in extreme cold like -35 Celsius I never turn it of.
Thanks for the great advice!!
keep giving us more of your Utube videos.
This is new to me and I appreciate your information. Thank you.
It’s extra wear on your compressor, mine went out while using it in the winter and I didn’t know it was broken until I needed it months later.
No it's not you need to lubricate the system at least
Great info! Hoping to hear back from you on Landcruiser set up.
Wait AMD...what if I don't have automatic climate control? Do I just turn the temp dial to warmer...say mid-level with the AC on?
Thanks
please talk about lighting a fire under the Engine in Siberia minus 60 degrees !
Would you do a video of transmission and motor mounts replacement, showing where to raise up the engine on a 2016 Camry, please? Do you need to raise up the engine at two different spots for transmission and motor? Thanks so much.
Hi! You’ll need to raise it from the oil pan near the drain plug that’s the strongest area
My Neon's all would turn the compressor on when I put the defrost on. It is good actually to run it during the winter they say, BUT it hit my mpg just like running it in the summer - at least I could tell it was kicking on and off. My Elantra does not do that and I actually like it .. even without having the deluxe defrost system they offer (it was a big concern, fortunately the "blower system" seems to function just fine .. until I go underground and the entire exterior turns to white frost .. thank goodness for heated mirrors, which I never had before and did not know how to turn them on for a couple months - I had learned to "use the Force" before that).
I live in the Chicago area and have a 2005 toyota 4runner and was wondering if you do any side work?
Hi! Email me with the subject Chicago service request
Interesting concept. Wondering what your take is on CVT transmissions? Also, do you have any experience with Subaru's ?? Thanks much
Hi! cVT transmission in Toyotas are reliable. I have some experience with Subaru. They’re good cars except their high performance models they’re nice but not very reliable
@@TheCarCareNut Thanks. Specifically, wondering if you have any thoughts on the Subaru Forester. I'm looking at that and the Rav 4. Can't decide.
Subaru past 10 years could cost more to maintain and could have more issues. Rav4s are a bit more expensive and has a less sophisticated Awd system than the Subarus. Depends on your plans for how long you’re keeping it and which one you like more
Great info as usual, thanks AMD
Do the new Camrys have AC clutches? I was just wondering if running the car with auto climate control on would take away from gas mileage. Thanks
most cars in the defrost cycle the ac automatically comes on
Not older shitboxes like my Nissan Sunny!
@Steven Strain The only way my Nissan ac is gonna go on is if I press the ac button. That will defrost the windows. Nice thing is I can use the heat with the ac, then it's really comfortable on a rainy wintery day. The ac removes the dampness.😊☺
@@BubblesTheCat1
Maybe that's because it's designed for cleaning dairy barns. 🤔🤪
I saw a video were cat litter was placed in a sock and put in the car it will help with codensation. Also does it help the seals andac compressor by running the lubricating oils in the freon?
Hi again, AMD. I have a '16 Sienna with only 45K miles. Original owner. The AC was working fine. Then one day the blower is on and fine, but there's no cold air coming out. Any suggestions on where I should start checking? Hope it's not too expensive. Appreciate advice - thank you.
When my now-wife and I were dating, she picked me up after work on a warm, rainy summer evening with her heater on full blast - it was a hundred degrees in her car. I asked her what she was doing and she said she was trying to de-fog her windshield (rather unsuccessfully). I turned on her a/c and, of course, the fogged windshield immediately clear up. I told her that the a/c was a dehumidifier, she didn't understand, and the conversation proceeded down the same road millions of husbands and wives have gone down. We had a similar discussion about putting large quantities of food down the garbage disposal. She's owned at least a dozen cars and has yet to read the owner's manual for any of them.
I've been told that even when the AC button is not "on" the compressor will still work when you use the defrost air vents...
Does it use hot gas bypass valve in low load situations?
Great video AMD!! I’m in Florida but good to know that. Thank you!
Good to know! Thanks, AMD!!!
❤❤
Great advice!! Thank you for sharing!!
Windows fog up because they're cold, not because the humidity is less on the outside. Air can't hold as much moisture when it's cold, and the air next to the glass is cold so the moisture condenses on the windows.
Doesn't the AC come on automatically when you use the defroster?
Good to know, thanks. How old are the 'older cars' that wouldn't have the modern A/C functionality? Are we talking 70's/80's cars or would a car from the early 2000's, like my 02 Corolla, be included in that category, which means its A/C might actually get damaged if it's kept on in Winter?
02 has a computer he's talking like 70's 80's maybe even 60's
Good info! Is that a Corolla Cross? I’m still waiting on mine..
I was told by a car guy years ago to keep the ac on year-round.
Turn ac on as cold or hot in winter, or both is fine?
As someone who wears glasses, this helps defog my glasses and I can see clearly :)
Thanks for sharing this video, interesting information.
I use the front windshield defroster - and that keeps the windows free of any humidity.
Is the defroster the same as the AC ?
Love your channel ...
Super Awesome Tip!!!!!!!
Is this true even in my ‘ancient’ 2021 4Runner? The temp sensor for the AC compressor?
Can you make a video on topping freon on a older Camry (2012) air conditioning unit. God bless 🙏
If I leave my climate control on AUTO in my Lexus GS 350, it will run the compressor all year round. There are times where the external temperature is cooler than my interior set temperature, and the exterior humidity is low. The compressor still runs. It just doesn't seem very efficient at times. Should I leave the climate control on full AUTO year round?
When I press the AUTO button and set a temperature I want, is the car able to control it's HVAC systems properly or should I control it manually?
I have 2021 Toyota Camry 4 cylinder and the gas pedal is so hard and stiff to press my foot is hurting me now so bad is there anything I can do about it
