Still have an R-22 refrigerant AC system in your Phoenix, Mesa, or Chandler home? Sapper HVAC explains why R-22 systems are a ticking clock in Arizona and what to do.
If you own a home in Phoenix, Chandler, Mesa, Gilbert, or anywhere in the Phoenix metro area that was built before 2010, there's a reasonable chance your air conditioning system uses R-22 refrigerant — also known by the brand name Freon. If that system develops a refrigerant leak, you're facing a difficult and expensive situation. Here's what you need to know.
What Is R-22 and Why Is It a Problem?
R-22 (chlorodifluoromethane) was the standard refrigerant used in residential air conditioning systems for decades. However, R-22 is a hydrochlorofluorocarbon (HCFC) that depletes the ozone layer. Under the Montreal Protocol and subsequent EPA regulations, the manufacture and import of R-22 was banned in the United States as of January 1, 2020.
This means R-22 is no longer being produced. The only supply available is reclaimed and recycled refrigerant — which is increasingly scarce and expensive. What once cost $5–$10 per pound now routinely costs $50–$150 per pound or more.
How Do You Know If Your System Uses R-22?
- Check the data plate on your outdoor condenser unit — it will list the refrigerant type
- If your system was manufactured before 2010, it almost certainly uses R-22
- Call Sapper HVAC — we can identify your refrigerant type during any service visit
What Happens If Your R-22 System Develops a Leak in Arizona
Option 1: Repair the Leak and Recharge with R-22
If R-22 is available and the leak is repairable, this can restore your system temporarily. However, R-22 may cost $50–$150 per pound — a system that needs 3–5 pounds recharged can cost $200–$750 in refrigerant alone. You're investing money in a system that uses an obsolete refrigerant with no long-term future.
Option 2: Convert to R-410A Drop-In Refrigerant
There are R-22 "retrofit" refrigerants designed to work in R-22 systems without full replacement. These work in some cases but are not ideal for Arizona's extreme operating conditions.
Option 3: Replace the System (Usually the Right Answer)
For most Phoenix metro homeowners with aging R-22 systems, system replacement is the economically sound decision. An R-22 system is at least 14–15 years old, past Arizona's expected system lifespan, running on obsolete refrigerant, and likely at or near end-of-life for multiple other components.
The Proactive Approach: Replace Before It Fails
- You control the timing — plan the replacement in spring at your convenience, not in a summer emergency
- You can shop for the best system and price without desperation
- You eliminate the risk of a system failure during Arizona's most dangerous summer heat
- New systems qualify for APS and SRP rebates
- New high-efficiency systems begin saving you money on your electric bill immediately
