Have an Older A/C? Why the R-22 Phaseout is Important To You

If you still have an older A/C unit, the R-22 phaseout is of concern. Because of depletion of the ozone layer, the federal government, in accordance with the Montreal Protocol of 1987, has cut the production of R-22, the refrigerant which most residential air conditioners have used for many years, to 25 percent of capacity. This has resulted in the cost of R-22 tripling in the last two years. Price will probably keep rising as production will be cut to 10 percent of capacity on Jan. 1, 2015. By 2020, R-22 will be phased out of production. The only remaining supply will be recaptured from existing units. 

What does this mean for you? Your Broken Arrow A/C unit could cost as much to recharge once as it would be to retrofit it. Retrofits can be made with parts that use R-410A, R-407C pure refrigerant or HFCF (hydrofluorocarbon) blends. Each has advantages and disadvantages.

R-410A is a cheaper, less efficient replacement refrigerant. It works in a higher pressure system than R-22 so several components in your unit would need to be replaced for it to work correctly. This makes it a mid-range expense and one that we suggest only if you cannot afford a new unit.

R-407C is another mid-priced option. This refrigerant requires the addition of a special lubricant to work in your older unit. It is nearly as efficient as R-22, but the cost to add the lubricant offsets some of the savings.

HFCF blends are considered only for units that are in extremely good condition. Those with leaky seals or broken gaskets cannot be retrofitted to this option. The refrigerants used (R-438A and R-422D) work with your existing gauges and offer comparable efficiency to R-22.

If you have the money, we suggest buying a new, more efficient air conditioner. The R-22 phaseout could be a catalyst for upgrading to a unit up to 50 percent more efficient than the one you are currently using.

Phasing Out R-22: Costs Are Rising, Supplies Dwindling

Phasing Out R-22: Costs Are Rising, Supplies Dwindling

Air conditioners use refrigerant to cool indoor air that passes over the cold, refrigerant-filled coils. If your air conditioner was manufactured prior to 2010, there is a good chance it requires R-22 refrigerant, which means you will begin to notice continuing annual increases in maintenance costs because supplies of R-22 are dwindling.R-22 refrigerant is a hydrochlorofluorocarbon (HFC) that emits ozone-depleting chlorine. As such, the Environmental Protection Agency (EPA) has set strict limitations on it's production for use in commercial and residential A/Cs through 2020. After that, the only way to recharge equipment requiring R-22 will be to capture and recycle it from phased out units. The extra labor costs, as well as the rising refrigerant costs due to lack of supply, will be transferred directly to the consumer.To give you an idea of how this has affected the HVAC industry:

• As of 2010, manufacturing HVAC equipment requiring the use of R-22 has been prohibited.

• Newer air conditioning systems are being manufactured to be compatible with refrigerants that are less harmful to the ozone, predominantly R410A.

• R-22 production is being increasingly limited. In 2011 the EPA permitted 100 million pounds of virgin R-22 to be brought to the market. In 2013, that number is reduced to 39 millions pounds. By 2020 it will no longer be manufactured.

To prepare for the R-22 phaseout:Verify the type of refrigerant you need. If you haven't scheduled your A/C maintenance yet, now is a good time to make an appointment. Ask the technician whether or not your unit requires the use of R-22. If it does, you will need to begin preparing for increasing refrigerant costs over the next several years.Replacement in coming years. If your unit was made prior to 2010 and it requires R-22, you should begin thinking about an eventual replacement.Beware of alternative refrigerant options. You may have read alternative refrigerants, such as R-407C, R-438A and R-422 are compatible in an R-22 system. Unfortunately, they can seriously compromise your equipment.Contact Air Assurance to learn more about your options during the R-22 phaseout.
