Do you know what type of refrigerant your AC system uses? In case it’s the once popular type of Freon for AC known as R-22, HCFC-22, or chlorodifluoromethane by its scientific name, then you might want to consider replacing your AC system. That’s because a protocol signed in Montreal, in 1992, agreed that this substance, […]

Thomas Midgley, Jr By Betty Stephens Inventor of Freon and Leaded Gas Thomas Midgley, Jr. (May 18, 1889 to November 2, 1944) was an American mechanical engineer and chemist. He was a key figure in a team of chemists, led by Charles F. Kettering, that developed the tetraethyl lead (TEL) additive to gasoline as well […]

Drop-in Refrigerants Replace R22, that Mix w/ R22 By Betty Stephens R22 Drop In Replacement R22 is the most common refrigerant in residential and light commercial A/C applications. It has been phased out due to damage that it does to the ozone layer, so availability is limited to existing stockpiles and refrigerant recovered from decommissioned […]

Phase Out of R22 in 2020 By Betty Stephens Chlorodifluoromethane, better known as HCFC-22 or R-22 is a common refrigerant that is currently being phased out in the U.S. due to its very high potential to exacerbate ozone-depletion (R-22 is also a global warming gas). U.S. EPA has tried to reduce use of this material […]

EPA Regulations on R-22 / SEER Ratings By Betty Stephens of Quest Media The EPA has begun phasing out the production of R-22 and has banned the production of HVAC equipment that uses R-22 in compliance with Title VI of the Clean Air Act. The refrigerant that replaces R-22 is R-410A. R-410A is an HFC […]

This video shows refrigerant recovery on a commercial package unit. The process is the same on a residential unit. Your unit at home is just smaller and a different shape, but the same principals and procedures apply.
