Recharging & refrigerant (freon) for the auto A/C
Q: How often should my A/C system be recharged?
A: Your auto A/C system is a closed and sealed system and (in theory) should not require regular service or recharging unless the system is being opened for service. However, the systems do leak (over time) as no seal is absolutely 100% leak free. You must also realize that compressor shaft seals (which require lubrication with refrigerant oil in order to hold their seal) will leak when the A/C system is not operated for extended periods of time (like over winter months). Therefore, as long as your A/C system is cooling properly, there is no reason to have to recharge it. Should you notice a drop in cooling, it should be checked and serviced and will most likely require recharging. Complete information and details on how to recharge your A/C system are available here. Just keep in mind that continued operation of a poorly cooling A/C system could cause sever damage to your A/C compressor! How can you tell? Just have a look at your orifice tube. Every orifice tube will tell a story about the condition on your A/C system. When your orifice tube is restricted, you have a serious problem that requires immediate attention and your entire A/C system will have to be flushed!
