In other words, your air conditioning system has nothing to work with! Another more serious symptom of low Freon levels is visible leaking. If you notice a leak, you will know it's Freon if it appears as a 'thin' greasy substance. These leaks often appear under the hood around the compressor, inside the cabin, or leaking under your vehicle. An ASE-Certified technician would check the system's pressures with gauges, and then identify any possible leaks. If a leak is found, the technician will repair the leak before refilling it with fresh refrigerant.
Published by Integrity 1st Automotive on August 6, Categories Vehicle Air Conditioning. Adding Refrigerant to a vehicle does not require a draw down or evacuation of the system.
However if the system has a leak and has been repaired or if it has been open at some point then yes an evacuation definitely would be required and would best be taken to an A. Reply 2 years ago. It does require to be evacuated before any repairs are made and then vacuumed down before refilling.
Question 3 years ago on Step 7. I replaced my compressor. Standard practice is vacuuming the system. Or just filling it will work. Question 2 years ago on Step 7. As an automotive technician i find this is a good write-up. However i need to make a few comments. When adding its always best to hold the can upside down since its a liquid refridgerant.
Also adding refridgerant to an empty system is something that needs to be left up to the professionals as the system needs to be properly vacuumed down and kept under a vacuum until refridgerant is added. Overcharging a system can in fact blow it up. This process can in fact be very hazardous if done improperly and there are so many factors involved with the vehicles AC that can cause a properly charged AC system to not function correctly.
If you dont know much about cars id suggest leaving this process up to the professionals. I have a question. I let someone put the freon in my car day before yesterday. While he was putting in a second a loud noise came from under the hood.
Looked as though spraying from the connection of the freon can and instantly it looked like clouds of smoke coming from the opposite side under the hood. It was making this loud screeching noise. It stopped until earlier when i turned the ac on and smoke was coming from under the hood and the loud screeching until i turned it off What did he do to it???
Its severely overcharged and he blew out a gasket or compressor pressure relief valve from my guess. This was one reason for my comment. Question 2 years ago. What did he do to it. He overcharged it and blew a gasket or the pressure relief valve on the AC Compressor from the sounds of it.
This is one of the main reasons for my comment below. Tip 2 years ago on Step 2. To use a self sealing can, you also need an adapter. Screw the adapter onto the dispenser first. Then screw the can to the adapter.
Without the adapter, the can screws on but remains sealed. Both valve are the same size so I took them to auto avance and they were not able to figure out as well.
Can you tell me what I need to know or how do I got by finding out without going to the dealer. Sorry if I use the word valve but I dont not know the right term. Follow the lines from the compressor.
The high pressure line will go towards the coolant radiator. The low pressure line will go to the passenger compartment. Did you make this project? Related repairs or maintenance may also be needed.

Your air conditioning system uses a special refrigerant called Ra to remove moisture from the air inside your car and deposit it outside. Over time, this refrigerant can escape, either through normal evaporation or through leaks that form in your system. Without refrigerant, the AC can no longer cool down the inside of your car. Recharging the AC is simply the process of adding more refrigerant to the system so that it works properly again.
This will prevent additional damage from occurring. Often, a simple DIY recharge kit will get your AC going again, especially if it only just started to fail.
The equipment alone places this job well out of reach for the average DIYer. If you do, then you might want to tackle an AC recharge on your own. As long as it does, that likely means that your compressor is working fine and that you just need to add some refrigerant to your car to get the AC system working again. Doing that is often as easy as attaching the recharge hose from your kit and using it to add more refrigerant to your AC system until there is enough of it working its way through the system.
You can have the AC system in your car blowing ice-cold air again in no time by taking these steps. The last thing you want to do is attempt to save a few bucks on the AC recharge cost and end up doing damage to your AC system or to your car as a whole. Most mechanics are well-versed in working on the AC systems in cars and can recharge your AC system without a problem. You might be surprised to see how many AC specialists that are in your city or town.
They can provide you with the AC recharge that you need and do it without subjecting you to a high AC recharge cost. But there is still one question hanging over your head: How much will an AC recharge cost? That will be great news for those who are worried about having to pay a small fortune to get their cars to blow cold air again.
