How do I know if my central A/C system uses R-22?


Ten years ago, the EPA mandated a complete phase-out of the production or import of R-22 by January 1, 2020 to protect the Earth’s protective ozone layer. R-22, a refrigerant also known as Freon, was commonly used in the production of air conditioning systems before 2010.

The easiest way to check if your central A/C system uses R-22 as a coolant is to look at the data plate on the outdoor condensing unit. Below are two examples of data plates.


The beginning of the cooling season is when we see most issues related to R-22 arise. Frozen lines are usually an indicator of a coolant leak. We will try to repair the leak if possible. If we cannot identify the source of the problem or if your system requires a large amount of R-22, we typically recommend replacing your unit. In our experience, we found that if a system requires a recharge of R-22, it will typically need more added again in a short amount of time.

As the supply of R-22 decreases, it may cost hundreds of dollars for only the refrigerant and any future problems would be even more expense. There are several advantages to consider upgrading your R-22 system including greater efficiency, reduced cooling costs, improved reliability and better for the environment.

If your A/C system uses R-22, has had performance issues in the past several years, we recommend being proactive in considering replacing it this summer. We have a variety of ways to help make the upgrade more palatable including manufacturer and utility rebates, special financing and loyalty points.
