Freon and Puron: What’s the Difference?

If the air conditioner in your Sarasota, Florida, home uses Freon refrigerant, you should know about its environmentally friendly replacement, Puron. Due to its ozone-depleting properties, Freon is no longer being used in air conditioning equipment, and newer air units are using Puron as a refrigerant.

What Is Freon?

Also known as R-22, Freon is a refrigerant commonly used in air conditioners. A hydrochlorofluorocarbon, or HCFC, Freon depletes the ozone layer. As a result of this destructive property, the U.S. Environmental Protection Agency (EPA) has committed itself to phasing out Freon use.

Manufacturers can no longer sell new air conditioning units with Freon. Importing and producing Freon in the United States will also decrease each year going forward until 2020, the year Freon imports and production in the United States will end.

What Is Puron?

Known as R-410A, Puron is a popular alternative to Freon. An environmentally friendly refrigerant, Puron does not release HCFCs into the atmosphere. Since Puron requires a higher operating pressure than other refrigerants, an air conditioning unit with Puron uses different parts than a Freon unit.

Using Puron allows an air conditioner to draw less power, which allows the unit to reach a higher operating efficiency.

What Does This Switch Mean for Homeowners?

If your current air conditioning unit uses Freon, you can still have it serviced and maintained. However, in the future, the price of Freon will likely increase along with its availability, making it more difficult to maintain your unit.

Retrofitting a Freon air conditioner to using Puron can be completed, but because of its higher pressure, a professional needs to replace both the unit’s condenser and system coil, which usually isn’t cost effective.

To prepare for total phaseout of Freon, you’ll need to soon think about replacing your air conditioner with a new unit designed for use with Puron. This switch is especially important if your current unit needs replacement or is nearing the end of its useful life.
