Is Freon expensive or hard to find?
Why is Freon so expensive? Because Freon is becoming so hard to find, the cost to buy it has surged. It’s the principle of supply and demand—as the supply has dropped, the price has surged, and will continue to surge until the demand for it disappears.
What type of Freon does a home AC use?
R22 (also known as HCFC-22) is a chlorofluorocarbon (CFC) once widely used as a refrigerant. If your home or office AC is over 10 years, then it’s probably using R22 as its freon. However, R22 Freon is banned in the U.S. today.
