Does my car AC Need freon?
Room Temperature Air A functional AC system should blow cool air, assuming it’s set to cool air. If your vehicle blows room temperature air instead, it could be a sign of low or empty freon, in which case you may need to recharge it.
How do you refill Freon in a car?
To fill the system with refrigerant: Squeeze the trigger for 5-10 seconds, slowly tipping and shaking the can. Wait 30 seconds for the pressure to equalize. Read the pressure displayed on the gauge again. When the pressure is correct, stop filing the system and wait a few minutes.
How long can Freon last?
Freon (which is really just a particular brand of refrigerant) lasts forever. It’s not like gas in car; it does not get “used up.” You see, your air conditioner’s refrigerant system is a “closed/sealed system,” meaning that it does not allow refrigerant to escape in any way.

Professionals can do it in less than an hour. As a DIY project, it can take 2 hours. However, it must be noted that the main time-consuming thing is locating and fixing a leak that causes the AC system to lose pressure. The actual recharging process is not that long.

Is Freon the same as refrigerant?
Freon is a non-combustible gas that is used as a refrigerant in air conditioning applications. This freon undergoes an evaporation process over and over again to help produce cool air that can be circulated throughout your AC system.
Why is my AC not cold after recharge?
Compressor If your car A/C stopped blowing cold air all of a sudden, it’s likely your compressor needs to be replaced. The compressor is the engine that drives the entire A/C system.
