Your mechanic may bring up recharging your AC with you if they notice your AC isn’t cooling your car properly. Your car may need that AC recharge if it is low on refrigerant, used by air conditioners to maintain cooling and pressure. A fresh batch of refrigerant, or Freon if your car needs it, will help your air conditioning system keep cool. When you get your AC recharged your auto repairer will fill up your air conditioning system with a fresh batch of refrigerant to go along with any repairs your AC may have needed, and test your system to ensure your AC is cooling thoroughly. Typically your car shouldn’t need an AC recharge unless you’ve had other repairs to your AC system, but your mechanic will suggest a AC recharge to you if they feel your AC could use one.
