In the United States, hydrochlorofluorocarbon (HCFC) refrigerants are being slowly phased out from production or being importing. The U.S. Environmental Protection Agency (EPA) still allows many of these types of HCFCs refrigerants to be used in repairs or retrofitting. However, without new production, the cost is becoming more...
When working with refrigerants like R22 and R134A, it's important to know what their Global Warming Potential is. Knowing the refrigerant's GWP is crucial for many reasons, especially when charging, sealing and other tasks so you may continue to work responsibly with such materials.
R22 refrigerant is a colorless gas known chemically as hydrochlorofluorocarbon 22 (HCFC-22) and is one of several refrigerants that goes by the brand name "Freon." It's used in a wide variety of applications, including central HVAC,...
When conducting repairs or diagnostics on a commercial cooler or freezer with R404a refrigerant, checking the pressure is key. However, in order to know the proper pressure, you also need to identify the correct corresponding temperature. The chart below helps you know what pressure R404a should run at.
