A common cause of a car's AC not working is a loss of refrigerant, generally caused by a leak. A mechanic should drain the system, find and fix the leaks until the system can hold pressure, then refill the system with a proper amount of refrigerant. However, this system can be used to pump refrigerant into the system until a certain pressure is reached. The problems are: (a) there may still be a leak; (b) the refrigerant is supposed to be measured by mass, but these self-service tools can only measure by pressure so it might be off; (c) many bottled refrigerants contain sealants that may cause trouble down the line; (d) the system needs oil, which is not being supplied; and (e) the system may now contain moisture.

If you have a car 1994 or newer and the air conditioning doesn't blow cold this kit will allow you to add Freon so the air conditioner works for a while.

Of course if your car is low on Freon that likely means you have a leak. To fix that you would need to take apart all the hose connections and replace the o-rings, then use a vacuum pump to evacuate the system and then add Freon. Of course the cost for all the equipment to do all that is roughly the same as taking the car to a mechanic and saying fix my air conditioner.

Unless you system has a total / almost total loss of pressure you'll be fine, slow leak, perhaps taking years between 'charges.' If you have a bad leak, recharging will not likely help for days if at all.

That is why god created pressure-temperature charts (that can be found online and normally come with these kits)

That has not been the case for decades. The sealants no longer not 'gum up' internals like in the days of ol. They only react to the presence of moisture* and sometimes cause o-rings / gaskets to swell (making a tighter seal).)

Unless you had a complete blow out, oil is still in the system. Also many of these kits do supply some oil. Also they tend to contain *moisture neutralizers for inside the refrigerant loop (and preventing sealants from reacting where they shouldn't). There are many recharge kits: with oil, without oil, with sealants, without sealants, with UV dye, without dye, moisture neutralizers, no moisture neutralizers, or pure refrigerant if you don't like additives.

But you are right, in a perfect world you'd drop your car off at a mechanic then pickup your revitalized AC a day later. But that $1000 difference in price is where the problem is. $30 does have a few downsides over actually doing a true "repair" but if it fails, you'll be a square one either way.

All vehicle A/C systems lose refrigerant over time. It's part of the design. If it's going away via a slow or fast leak, that's a sign of trouble.

You have to measure the amount of refrigerant oil removed from the A/C system during evacuation. Systems usually doesn't need oil, 99% of oil is still there and is not going to leak out unless you have a total failure. A common mistake is to pump out R134, then to refill the system to the max with all the oil added (8-10 oz). It will overfill the compressor with oil. There is an oil separator in the A/C compressor which sends most of the oil back into the compressor. This results in a thinner oil film inside of the heat exchangers (A/C condenser and evaporator), but no more than that. Pretty much it is impossible to add the correct amount of oil into the leaked system without replacing or draining the compressor and also draining it out from all the low parts. See this for more info. It is very tricky https://tccimfg.com/wp-content/up...alance.pdf For a regular expected leak over the years (all o-rings very slowly leak refrigerant, SAE acceptable leakage rate of 1/4 ounce of refrigerant per year per fitting) just skip the oil part

My truck needed recharging every year, which I did so myself for several years. I tried a sealant, and although it never got better, it didn't get worse either. Nothing got worse over the years.

This. Just dont do it. The proper measurement is based off the weight as mentioned. It's stupid easy to over fill an ac system with these diy kits then you have to pay a shop to suck it out, test if it holds a vacuum and verify you didn't damage anything and refill. AC is something best left done to the pros.
Kits like these are perfect for college kids driving 20 YO beaters that you're just trying to get through another summer and get to work without being soaked in sweat.

If you are trying to keep your car for another a few/many years or are hoping to keep the resell value high, consider taking it to a shop.

Assuming you have the money, which many people just don't.

Edited for clarity.

This is better than getting the $3-4 adapters for the "self seal" tops that are now being used to eliminate freon into the air. At this price, I will get 2 -- one as a backup.

Thanks for sharing this one!

I thought they dont use freon anymore because it destroys the ozone?

Yes my mechanic wanted 1000 bucks to fix air conditioner due to leaks. But stupid me put in the acpro in my system. And it only lasted 8 years of super cold . Now I had to add another can of acpro and now it is way colder. Now I think it will only last maybe 7 years .

I guess I should paid the 1000 bucks .... 🤭

R-12 refrigerant was banned and R-134a is it's replacement in automotive applications.

99% of the time these don't work

You either have a leak or the blend control unit is bad.

If there's a leak, then you need to have the leak fixed or have it fully evacuated and then vacuumed and refilled, which this won't do.

Save your money and skip the do it yourself things ...

99% of the time your R134 has slowly leaked out due to industry standard expected 1/4 oz/year leak per each fitting. There is nothing to fix. I'm not suggesting this tool as a replacement to a proper manifold gauges, but it is day and night better than no tool at all or better (or not) than a crappy gauge on the R134 bottle from Walmart.
People who use this device do not have $200+ to go to service and do full evacuation which is actually not needed if you are just adding 2-3 oz of R134a

So are Kleenex and Xerox. I assumed that on a non-technical board like SD that most readers could figure out that my use of the word Freon meant a refrigerant and that I wasn't specifically referring to R12.
