Chlorodifluoromethane, commonly known as R-22, is a chemical compound used for refrigeration purposes. Although numerous home cooling systems contain this gaseous substance, R-22 reliance is currently being phased out in the United States due to its hazardous environmental impact.
What’s Wrong with R-22?
When released in bulk quantities, this chemical causes ozone depletion and significantly increases the risks of global climate change. In fact, R-22 emission — among other hydrofluorocarbon compounds (HFC) — can be 10,000 times more potent than carbon dioxide, per ounce.
To counteract these ozone effects, the Montreal Protocol — an international treaty that promotes the disuse of harmful substances — will mandate reduced “consumption of HFCs by 99.5% below the U.S. baseline” by 2020. Recycled or reclaimed refrigerants will be permitted, but after the deadline, chemical manufacturers cannot produce R-22 for air conditioner maintenance.
Are There Any Alternatives?
In response to this phase-out, corporations and government agencies are developing more eco-friendly coolants. Since 2010, the Obama Administration has partnered with companies to avoid R-22 environmental leakage from houses, cars or offices. These voluntary participants represent a chemical manufacturing coalition that comprises 95% of U.S. HFC production.
The current leading R-22 alternative in residential HVAC equipment is called R-410A, and this refrigerant provides effective home ventilation without contributing to ozone depletion.
Why Make the Switch-Over?
As the government decreases R-22 production over these next several years, homeowners who still utilize this chemical coolant will experience a dramatic upsurge in A/C servicing costs. Moreover, since these outmoded units were taken off the market in 2010, basic R-22 maintenance parts have become increasingly scarce — for both commercial and residential purposes.
Conversely, installing an R-410A air conditioner offers numerous benefits to both consumers and the atmosphere they breathe. This refrigerant does not cause ozone depletion, and HVAC machinery that operates on R-410A earns a higher Seasonal Energy Efficiency Ratio (SEER) rating than its noxious counterpart. So, if your A/C unit’s nameplate or owner manual identifies it as “R-22,” seriously consider upgrading to the safer and more efficient “R-410A” model.
Ask yourself the question — “Does my household contribute to environmental protection, or is my ventilation system wasting energy and releasing harmful fumes into the atmosphere?”
