What is R-22?

R22 refrigerant, also called hcfc 22 or Freon, is one of the most widely used cooling gases in older residential and commercial air-conditioning systems. For decades, it was the standard choice thanks to reliable cooling performance and broad equipment compatibility.

Although new systems no longer use R22 due to environmental regulations, many existing units in the U.S. still depend on it. If your AC or refrigeration setup requires R22, our 30lb EPA-certified cylinders provide the supply you need to keep it running smoothly

What is R-404A?

R-404A is a refrigerant blend made from R-125, R-143a, and R-134a. It is commonly used in medium and low-temperature refrigeration systems such as supermarket freezers, cold storage rooms, and transport refrigeration. Customers choose R-404A for its strong cooling performance and dependable operation compared with older options like R-22.

Systems built for R-404A typically use POE (polyolester) lubricants to maintain compatibility and efficiency. Some older refrigeration setups can be converted to R-404A with the right adjustments, and professional guidance is recommended to ensure reliable results.

R-404A is classified as non-toxic and non-flammable under the A1 safety rating. As the market moves toward lower-GWP choices, many new installations consider alternatives, but R-404A remains widely available for existing equipment that still relies on it
