The deadline has passed. The R-410A transition is in full swing. But, wait! Millions of R-22 split systems are still in service. They'll continue to need service for years to come. What's a dealer to do?

Start with these five tips:

The U.S. Environmental Protection Agency developed the rules for implementing the phase-out of R-22 in the United States. They are posted here on the EPA Web site.

Manufacturers can no longer build new condensers charged with R-22, but you can continue to use remaining inventories of new R-22 condensers to service existing R-22 systems.

 
Since evaporator coils are not factory-charged with refrigerant, EPA rules allow continued production of R-22 evaporator coils. The EDM2X coils are still in the 2010 Tempstar product line:

You have two options:

♦  If R-22 components are still available… you can use them to replace both the evaporator coil and condenser. 
♦  HOWEVER... a better option for the customer may be to replace the entire system with a new R-410A based system. 

Several Tempstar mainline accessory kits are available that allow selected models of R‑22 Tempstar equipment to be converted to R‑410A refrigerant. Also, components are available from FAST parts to accomplish a conversion. Refer to the chart below for available kits, part numbers, and applications. Click here for more information.

If you convert a coil, remember two important notes:

♦  For Non-Rated Installations Only. Converted coils are only appropriate for situations that do not require a documented AHRI rating. Typically, these would be service situations or new 13 SEER installations where there is no code, rebate or homeowner requirement for the AHRI rating.

♦   Mark the converted coil. When you convert a coil from one refrigerant to the other, do the right thing and mark that coil to indicate the refrigerant change. Mainline accessory kits include a label that’s intended for that purpose. If you don’t have a label, use an indelible marker to write a note near the rating plate.
