What is the difference between 134a and 1234yf?

Refrigerant R-134a, also known HFC-134a, is a hydrofluorocarbon (HFC) refrigerant. HFO-1234yf is a hydrofluoro-olefin (HFO) refrigerant. … However, with HFC refrigerants, the atoms are connected by single bonds between the atoms, whereas the atoms in HFO refrigerants at least one double bond between the carbon atoms.

How much is 1234yf freon?

The national average price of an R134A recharge in 2018 was around $200-$300 with the cost of the previous standard R134A refrigerant at $30 per pound. However, the average current market price of the R1234yf refrigerant is $120 per pound.
