How will the r22 refrigerant phase out impact you?
In 1987 the United States signed the Montreal Protocol, promising to reduce the amount of hydro chlorofluorocarbons (HCFCs) used in order to help protect the environment. Limits on the amount of HCFCs used were later modified, calling for a complete ban on their use by the year 2020.
HCFCs have been shown to deplete the ozone layer and one of the primary uses of HCFCs is in residential air conditioning units, but studies have concluded the Freon that was used for over 40 years, r22 also worked as a greenhouse gas when released into the atmosphere. While the Environmental Protection Agency has issued strict regulations regarding the reclamation of r22 when servicing air conditioners, the Montreal Protocol has gone the added step of banning its use altogether after 2020.
At the start of 2010, use of HCFCs in the United States was mandated to be 75 percent lower than a baseline amount established by the EPA. It is being replaced by r410a refrigerant in all residential air conditioning units and by 2020 will be completely phased out. Although it will still be available for another eight years, its cost will be significantly higher due to a lack of supply.

Unlike many alkyl halide refrigerants, it does not contribute to ozone depletion, and is therefore becoming more widely used as ozone-depleting refrigerants like R-22 are phased out. However, it has a high global warming potential (1725 times the eff

- A Comparison of an R22 and an R410An air Conditioner Operating at High Ambient Temperature
R22 and R410A split air-conditioning systems were tested and compared as outdoor temperature ranged from 27.8 °C (82.0 °F) to 54.4 °F (130 °F).
In 2010 the production or importation of r22 was limited for use in existing air conditioners but was banned for use in new equipment. Also in 2010, manufacturers of air conditioning units and heat pumps, abiding by the law, stopped making systems that use r22 refrigerant. The new r410a refrigerant operates at a higher pressure and the older equipment will not support its use.
The use of r410a in residential air conditioners was approved by the EPA after studies determined it did not affect the ozone layer. Regulations preventing it from being vented into the atmosphere remain in place as it has been proven to contribute to greenhouse gas.
Concerned homeowners do not have to immediately replace their air conditioning units since r22 will still be available for repairs and recharging for another eight years, but with its cost rapidly escalating, currently priced 3 times more than last year, replacement may be a less expensive alternative. The age of the air conditioner and the age of the refrigerant should be considered when service is required. The cost of r22 refrigerant has tripled over the past year, affecting the cost of recharging and repairing systems.
Additionally there will be no new r22 available as companies are not producing it anymore and service companies are relying on the refrigerant that has been reclaimed and recycled to service existing units. One replacement refrigerant, R-407C can be used as a replacement for r22, but the EPA has not approved it for use in the United States.
When homeowners consider servicing their existing air conditioning units, depending on its age and the type of Freon it requires, it may be less expensive to replace it with a new, more energy efficient unit. The cost of replacing any lost r22 may make the cost of repair higher than a new unit.
