hello Alex!!, the local ac expert here in Akron gives people with 1234YF systems the option to recharge with 134 he has done hundreds with no problems, he flushes them and changes to pag oil made a custom set of gauges that will connect to a 134 machine, he opened his shop in 1973 , not saying you should do it, so far I have been sending cars with 1234 to him, at 63 years old I am not going to buy a lot of new equipment, just wanted to let you know

Always change the high and low side charge valves with every A/C service you will save money in the long run I have done ac work for a long time when I started we used R-12 and had a sun ac machine. I still have two 30lbs cylinders of R-12 and five 134-A cylinders.

If a c is leaking and you cannot find a leak go check the drain plug for the heater box for the evaporated core

Alex one tip I will give you about GM cars is I always remove the orifice tube and check it for metal before giving an estimate, better to let them know the compressor may be on its way out before doing a pricey repair, they will not understand a few months later, better to do it now if it needs it, GM compressors do not like to run with low a low charge it is hard on them

Alex is correct, ac refrigerant will slowly make its way through rubber parts, if you are a pound low after 3 years that is a normal thing, just recharge it, a pound loss in a year indicates a leak that should be addressed, same thing happens with tires, you lose about 1 psi a month, over a year that is 12 psi, newer cars have plastic liners in the ac hoses that help but a recharge every few years is a good idea to keep it working correctly

Yall had me going I really was Getting ready to start snitching on shops 😂

I like the diag vids they are informative. It’s good to see where to look for specific problems that may arise. I may not be a mechanic or a home mechanic but it’s good to be able to have some knowledge about certain issues so you’re not getting shafted at the shop. Keep it up

Nice work Alex…👍👍

He definitely got lucky some of those CVts blow before 60k

Educational as always 👍🏾

Joe Jackson!!! 🤣🤣🤣 Mrs Car Doctor tickles us every time!!! ❤️

The AC systems lose refrigerant over time through the seals of the compressor. They all do, it doesn't matter what kind of car it is. Also they are much better with the CVT transmissions than they use to be. The first ones were horrible. I have an '06 Commander Limited Hemi that I have had since new. It needs an evaporator coil, yikes, expensive job. It is worth fixing because the vehicle has been garage kept and is still like new and only has 61k miles on it. We don't use it much since I'm retired, so convincing my wife to get it done has been unsuccessful at this time. We are running around in a Nissan Versa that I bought for work, and it has been a good little car.

Molecular structure of the gas is smaller then the rubber hose thus it allows small molecules out through the rubber

I keep a stock of the brass version of that rubber high side valve, the brass one has a real schrader in it

Snap-On needs to sponsor you

You can check high side psi with your scanner. And basically, is a check for Freon in the system

It’s a closed system if it’s low on gas wouldn’t that mean there’s a leak.

Is old school people just add Freon. F…k the ozone. We stand corrected. Thanks

I’m surprised you don’t use the vin number to determine the year of the vehicle and other information

Nissan hoses high and low side always leak very common.

Freezon breaks down over time and use Valves leak so do seals

My ex wife recently got rid of her 2009 Enclave with over 350,000 miles. Everything worked but the A/C and her catalytic converters needed to be replaced.

He took good care of that car

Does the A/C compressor need to have its oil changed and filled?

Something is wrong with the connector mine made same way never had any problems

Spider-Man Spider-Man me myself don't even understand what I really really have keep breaking down those walls man give thanks more fire 🔥🔥🔥🔥(book: the future of money and finance blockchain banking)

Brand new cars lose refrigerant it's normal

just use the bucket method. Jk i like the environment, it's very pretty

The rubber hoses are porous.

And the fine is $44.000 and some change a day, and you can lose your EPA.

Weed ain't a drug 😅. I do beer too

134a slowly seeps out into the atmosphere. How many vehicles out there slowly seeping Front end collision, poof!

Bizzy bone

Alex you can do what you want as it is your channel of course. But these diag videos are kinda long, meandering, and you don't really learn too much. Your more successful vids like "How to Bleed or "BURP" Air Out Of Your Engine Cooling" are tutorial videos focusing on specific DIY things. No hate, I just want to see you hit 100k by the summer.

I have had 1 vehicle with over 300,000 miles and two with over 280,000 miles never service transmission still see them around town going strong. only service coolant and oil.

Is old school people just add Freon. F…k the ozone. We stand corrected. Thanks
