What you should know about the phasing out of HCFC…
HCFC phase out what homeowners should know about , HCFC, R-22, HCFC-22 and what to consider when deciding to repair or purchase new air conditioners, heat pumps, or air handlers. Abraham Air Conditioninh and Heating can help you make the right choice give us a call today at 813-882-0999
HCFC-22 (also known as R-22) has been the refrigerant of choice for residential heat pump and air-conditioning systems for more than four decades. Unfortunately for the environment, releases of R-22, such as those from leaks, contribute to ozone depletion. In addition, R-22 is a greenhouse gas and the manufacture of R-22 results in a by-product (HFC-23) that contributes significantly to global warming. The governments EPA website has a fact sheet with information about the transition away from R-22, the future availability of R-22, and the new refrigerants that are replacing R-22. This document also assists consumers in deciding what to consider when purchasing a new A/C system or heat pump, or when having an existing system repaired.
You can find the fact sheet here HCFC Phase-out Fact Sheet on the EPA website and we have included some of the information below:
What Does the HCFC-22 Phaseout Mean for Consumers?
Servicing existing units
Existing units using R-22 can continue to be serviced with R-22. There is no EPA requirement to change or convert R-22 units for use with a non-ozone-depleting substitute refrigerant. Such changes, called “retrofits,” are allowed if the alternative has been found acceptable for that type of use. R-407C is allowed for retrofits but R-410A is not allowed in retrofits due to its higher working pressures. In addition, the new substitute refrigerants would not work well without making some changes to system components. As a result, service technicians who repair leaks to the system will most often continue to charge R-22 into the system as part of that repair.
Installing new units
The transition away from ozone-depleting R-22 to systems that rely on replacement refrigerants like R-410A has required redesign of heat pump and air conditioning systems. New systems incorporate compressors and other components specifically designed for use with specific replacement refrigerants. For instance, if a new outdoor unit (typically called a “condensing unit,” containing the condenser and compressor) is installed, it is likely that a new indoor unit (typically called an “evaporator”) will also be required. With these significant product and production process changes, testing and training must also change. Consumers should be aware that dealers of systems that use substitute refrigerants should be schooled in installation and service techniques required for use of that substitute refrigerant.
A Common Sense Approach To Purchasing New Systems
Another important thing a homeowner can do for the environment is to purchase a highly energy-efficient system. Energy-efficient systems result in cost savings for the homeowner. Today’s best air conditioners use much less energy to produce the same amount of cooling as air conditioners made in the mid-1970s. Even if your air conditioner is only 10 years old, you may save significantly on your cooling energy costs by replacing it with a newer, more efficient model. Products with EPA’s Energy Star® label can save homeowners 10% to 40% on their heating and cooling bills every year. These products are made by most major manufacturers and have the same features as standard products but also incorporate energy saving technology. Both R-22 and R-410A systems may have the Energy Star® label. Equipment that displays the Energy Star® label must have a minimum seasonal energy efficiency ratio (SEER). The higher the SEER specification, the more efficient the equipment. You should consider energy efficiency, along with performance, reliability, and cost, in making your decision.
