The only way to get a certain answer is to have a shop do a system performance test followed by a refrigerant recovery operation. There are several reasons a vehicle's AC system may not be performing sufficiently - low refrigerant is generally assumed to be the reason why by most motorists, but it's only one of several possible reasons. Additionally, if it did turn out to be low refrigerant, and the cause of this was a leak, you would want to be able to have the leak identified and repaired.
Freon may need to be added when the ac is not blowing cold enough. A Freon gauge can tell you for sure if the pressure is low.
On all years, makes and models you will need to go to any automotive a/c repair shop and have them reclaim this for you.... (Do not just let it out in the atmosphere this is illegal)....... Depending of if your have R-12 freon or R134A freon you can buy the R134a freon at any auto parts store but you need to be licensed to buy R-12 freon.........
the air coming from the vent is warm
I wouldn't pay anyone to do it, it'd probably by a lot more than to just do it yourself. You can get a can of it at auto zone or somewhere for about ten to twenty dollars and they should be able to tell you where the valve is that you put the fluid in. Second opinion: Your car should not need freon. If it does, then there is a leak, and it would be inappropriate to add freon without fixing the leak. Besides, it is possible to have too much freon, so you need to measure what was in the system. You need tools and equipment to do this, so take the car someplace and have it looked at.
yes but you need to how much freon if may not be cost effective. Plus you need to know if it is the same type of freon.
The exact amount of Freon that needs to be added to a Kia Optima is unknown. This is because if Freon is needed there may be a leak and the car will need to be taken to a mechanic.
the effectiveness of the compressor will be low and the temperature at which the environment is cooled will reduce.
where do u put freon in a smart cAR 2009
If you are only getting warm air out of the airducts with the AC turned on, it may be time for more freon. Also, if you hear a growling noise from the compressor when accelerating, that is also an indication of low freon.
Freon is odorless; you cannot smell it.
When you are going to add Freon to a Toyota Camry, you need to know which type to add. You will need to put the Freon recharging coupler to the recharging kit, and get the engine to operating temperature. When the engine is at operating temperature put the air conditioning on the lowest setting and recharge the Freon with the windows of the car rolled down.
Freon cooler is leaking from A/C system.
