Heating, Cooling and HVAC

Is it being phased out like the refrigerant in your car?

Unless a central home air conditioner is relatively new, the refrigerant used is R22. It is chemically different from the refrigerant used in an auto and has only one-twentieth the impact on stratospheric ozone. Because it is not as harmful to the ozone layer, it is not scheduled for phase-out until 2020.

Some air-conditioner manufacturers are offering equipment filled with refrigerants that pose no harm to the atmosphere. The operating efficiency of these air conditioners is no higher than those filled with R22.

These products may carry a higher price, but the refrigerants will be available after the scheduled 2020 phase-out of R22.
