Will adding refrigerant solve the problem? Quick Answer:
No. If your AC is low on refrigerant, there is a hole somewhere in the system. Refrigerant doesn’t get used up in normal operation, it’s sealed inside. Adding refrigerant without finding and fixing the leak is a temporary fix that has to be repeated.
R22 (older refrigerant): Especially expensive, on older units, replacement is often the better call.
Can refrigerant be topped off? No
Why it’s low: There is a hole, a leak
Right fix: Find the leak, repair it, then recharge

The Sealed-System Reality
There’s no topping it off. There’s a hole. Katie Hardy, HVAC Comfort (paraphrased, verify with transcript)
Refrigerant is sealed inside the AC. It is not consumed during normal operation. If the level is low, that refrigerant leaked out somewhere, and that leak is what has to be repaired.
R22 Makes the Math Worse
For older AC systems running R22 (the older AC refrigerant), “topping off” becomes especially costly. On a 12+ year old AC with an R22 leak, replacing the system often makes more sense than chasing the leak.

Frequently Asked Questions
Can I just add refrigerant to my AC?
No. Refrigerant doesn’t get consumed in normal operation. If the level is low, there’s a leak that needs to be repaired first.
Why is R22 a special case?
R22 is the older AC refrigerant. On older R22 units with a meaningful leak, replacement of the system often makes more sense than repair.
Is “topping off” ever the right fix?
No. It’s a temporary patch that doesn’t address the underlying leak.
