It is essential to ensure enough refrigerant in your air conditioner, as too little can cause the system to work less efficiently, and too much can be dangerous. The general guideline used when calculating the amount of Freon in a residential A/C unit is 2-4 pounds per ton of cooling.

Can you lose refrigerant without a leak?
