Does recharging your car AC work?

When your car's air conditioning (AC) begins to lose power and doesn't blow cool air, it may be time for an AC recharge.

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.

Let us find out how and why. You should run your car's AC for ten minutes in every couple of weeks. Even if you do not want your car to be any cooler, the experts advise that you should turn it on every now and then in the winter. Running the AC allows the coolant to move around the system.

Can you overfill your car's AC?

A: It is possible to overfill an air conditioner with refrigerant and, unfortunately, several problems can occur that could permanently damage the unit. To start, an overcharged air conditioning system will decrease both its efficiency and capacity to cool.

How do you know when freon is full?

Use the gauge that is attached to the hose to find out how much freon is in your AC unit. If the gauge shows refrigerant levels in the red zone, it means you have too much freon in your system, and this requires an entirely different service that may require a licensed technician.

Why is my AC blowing hot air after recharge?
