Frequently Asked Questions About Freon

What is R22 freon used for?
R22 is a refrigerant gas historically used in air conditioners and some refrigeration systems to enable the cooling cycle. It's the gas that gets compressed and circulated through the AC unit's coils to absorb and release heat, which is what produces cool air. Older AC units, particularly split units installed years ago, are more likely to still rely on R22.
What affects the price of R22 freon in Egypt?
Price is influenced by global refrigerant supply (R22 is being phased down internationally under environmental agreements, which affects availability and cost), cylinder/canister size purchased, and current exchange rates since refrigerants are often imported. Because supply is tightening as R22 is phased out in many markets, prices have generally trended upward compared to newer refrigerant alternatives.
Why is R22 becoming harder to find or more expensive compared to newer refrigerants?
R22 is an HCFC refrigerant being phased out globally due to its ozone-depleting properties under international environmental agreements, leading manufacturers to shift production toward alternatives like R410A or R32. As global production of R22 declines, remaining supply becomes costlier, which is reflected in rising prices for both the gas itself and servicing older units that still require it.
How do I know if my AC unit uses R22 or a newer refrigerant?
Check the nameplate or specifications label on your outdoor AC unit, which lists the refrigerant type it's designed for. Units manufactured roughly before the early-to-mid 2010s in many markets are more likely to use R22, while newer units typically use R410A or R32. A licensed AC technician can also confirm this quickly if the label is unclear or worn.
Should I keep topping up R22 in an old AC unit, or consider replacing the system?
Frequent need for refrigerant top-ups usually signals a leak in the system rather than normal consumption, since a properly sealed AC shouldn't lose refrigerant over time. Given R22's rising cost and declining availability, if your unit needs repeated top-ups or a major repair, replacing it with a newer R410A or R32 system is often more cost-effective long-term than continuing to service an aging R22 unit. A technician can assess whether repair or replacement makes more financial sense for your specific unit's condition.
