- Unpleasant mildew and mold odors emanate from your AC vents.

Freon Recharging FAQs
How often should Freon be changed?
Never, at least not in the way you think of your oil being changed. Your car's AC system is a sealed unit. No new Freon needs to be added unless there's a refrigerant leak. Over time as your vehicle ages small cracks may form in your AC system parts such as the compressor, condenser, evaporator, receiver-dryer, expansion tube and connecting hoses allowing Freon to escape. If this occurs, you need to replace the failing part and have your Freon recharged.
How long should a Freon recharge last?
If your car's AC system was recently repaired and required a Freon recharge it should not need to be replaced again. Your AC system is a closed or sealed system that does not allow Freon to escape. Freon is not like gasoline; it does not get depleted. If Freon is escaping after your car's AC system has been repaired, then additional work may need to be done to find the leak.
How many cans of Freon does a car take?
Don't guesstimate your car's refrigerant needs! Most use 28-32 ounces (2-3 12oz cans), but larger vehicles and rear A/C can be different. Check your manual for the exact amount to avoid overfilling.
Can I leave my car running when adding Freon?
It is advised to have your engine running while recharging your car's A/C system. This is essential as the A/C compressor, powered by the engine, must be active to facilitate proper refrigerant circulation and ensure an effective recharge.
Why is my car blowing hot air after adding Freon?
A refrigerant leak can lead to a loss of pressure in the AC system, resulting in a failure to produce cold air. This is frequently the primary reason a recharge may prove ineffective. It is crucial to inspect the system for leaks and address any issues before proceeding with a recharge.

Shirley Lomeli, 07/08/2026Art is your go-to trusted expert and a rare, extraordinary genius, kind and funny mechanic!! Very lucky to have met Art and have his outstanding help to resolve all my issues on my older vehicle that had several serious electrical problems (parasitic drain, instrument clusters on dash no longer working, and my driver seat button no longer worked) that no one else could help me solve!! Art is so smart and hardworking! Art is also very quick to get the work done especially considering older vehicle parts are very difficult to find, and yet Art kindly charges a very reasonable price. Art also replaced my badly leaking radiator thanks to him for carefully noticing this before I had an issue! Art was well worth the further distance I had to drive to but worth every mile! Art is very much loved and appreciated! Thank you so very much Art and for taking such amazing care of me!! :) You are the Best!
