Dry R-22 Units: What’s the Hype?


By now, you’ve probably heard about the “dry R-22” units that we are shipping. These units are replacements for existing R-22 systems. They are shipped dry, without refrigerant, and have a nitrogen holding charge. Once in the field, the technician must purge the nitrogen and charge the unit with R-22 refrigerant (here’s a video on how to properly install a dry R-22 unit).

Because these units are shipped without refrigerant, they are in compliance with EPA and DOE regulations. Yet, there is a great amount of controversy on whether these units are helping or hurting the industry as well as the environment.

At NORDYNE, we feel these units are positive all around. Here’s why:

    • Existing R-22 units are most likely less efficient than 13 SEER. By replacing these units with a 13-SEER dry unit – versus a repair such as a compressor change-out – we are increasing energy efficiency.
    • Dry R-22 units are not displacing R-410A sales. In almost all cases, the dry R-22 units are an alternative to repair or replacing with a window air conditioner.
    • Dry R-22 equipment provides the consumer with a more conscientious option for the repair choice that they are already making. This choice is more energy efficient, reliable and protects the environment due to the highest level of leak protection offered on all controlled production units.
    • It is a more cost-effective and less complicated install than using an R-410A outdoor component with an existing indoor R-22 indoor component.
    • There are still ample supplies of R-22 at fair prices.

While the still-sluggish economy recovers, dry R-22 units make good business sense for the heating and cooling industry as well as price-conscious consumers.
