Refrigerant Gas R404A is a colorless odorless mixture of three hydrofluorocarbon compounds in near-azeotropic proportions.

Air conditioners typically use refrigerants like R-410A or R-32, which are Hydrofluorocarbons (HFCs). R-410A is commonly used, while R-32 is gaining popularity due to its lower Global Warming Potential, according to Bajaj Finserv and FreQuip Rentals. Older ACs might use R-22, also known as Freon.

R-134a is a hydrofluorocarbon (HFC) refrigerant used in various refrigeration and air conditioning systems, including automotive air conditioning, household refrigerators, and industrial chillers.

R-410A is a hydrofluorocarbon (HFC) refrigerant gas widely used in air conditioning and heat pump systems.

Air conditioners commonly use refrigerants like R-32, R-410A, and R-22. R-32 is a hydrofluorocarbon (HFC) refrigerant with a lower global warming potential than R-410A, while R-410A is another HFC refrigerant widely used in modern AC units. R-22 is a hydrochlorofluorocarbon (HCFC) refrigerant, which is being phased out due to its ozone depletion potential.
