How Often Should You Add Refrigerant (Freon) to Your AC System in Southern Orange County?
If you’ve ever been told your air conditioner “just needs a little freon”, or that “it’s time to top off your system”, you might be wondering how often refrigerant has to be added to keep your system running effectively. Truth be told, if your HVAC system is working properly, you should never have to add refrigerant at all.
Do Air Conditioners Use Up Refrigerant?
No, they do not! Unlike gas in your car, refrigerant circulates in a closed loop. It’s designed to last for the life of your system. If your system is low on refrigerant (commonly called freon), it means you have a refrigerant leak somewhere.
Why the Misconception Exists
We’ve come across countless homeowners who have been told by contractors that refrigerant “runs out” over time. In reality, having to be “topped off” repeatedly means that there is a leak in the system that’s being ignored. This can cost homeowners hundreds of dollars every summer while masking the real problem.
Why “Topping Off” Isn’t a Long-Term Solution
Some HVAC companies will simply add refrigerant and leave. But if the root of the problem isn’t addressed, then:
You’ll need another recharge, sometimes within weeks if the leak is significant!
The system runs longer and less efficiently, which drives up your energy bill.
Running your system on a low refrigerant charge can shorten the lifespan of your compressor.
You may find yourself dealing with a water leak, as a low refrigerant charge can turn your indoor coil (evaporator) into a block of ice! This can cause significant ceiling damage or mold if it’s left unaddressed.
The Right Way to Handle Low Refrigerant
Depending on how low the system’s charge is, you may choose to top off the system and have a leak sealant installed. If this doesn’t work or you forego this step, then:
Perform a leak test to identify the source of the problem.
Repair or replace the leaking component.
Recharge the system with the proper refrigerant type and amount.
Confirm your system is properly sealed and running at peak efficiency.
Bottom Line for Orange County Homeowners
You should never need to “add freon” to your system on a regular basis. If you do, there’s likely a leak that needs attention. Addressing the root cause not only saves you money in the long run but also extends the life of your HVAC system. This will help keep your home comfortable through Southern California’s hottest months.
