Is it normal for car AC to lose Freon?

Freon is vitally important—losing even 10 percent of it can reduce your AC's efficiency by 20 percent or more—and knowing the signs of Freon loss is important to keep it running at peak capacity. You'll almost certainly notice the effectiveness of your air conditioning going into decline as the first sign.

How often should you add Freon to AC?

Never. You shouldn't have to “add” refrigerant to a central air conditioner because it doesn't “use up” refrigerant. The only reason you would ever need to recharge (that is, add refrigerant to) your A/C is if you have a leak; once the leak is fixed, the problem should be solved.

What causes Freon to leak out?

4 Causes of Refrigerant or AC Freon Leak

Age-related wear and tear are a common cause of air conditioner refrigerant leaks. Over time, the joints and connections in your AC can weaken and erode. In addition, rubber seals around the service valves, or access fittings, can wear out and cause the refrigerant to leak.
