What New Jersey Homebuyers Need to Know About Air Conditioning Systems and R-22 Refrigerant

When purchasing a home in New Jersey, one of the most overlooked—but critically important—components is the air conditioning system. As a home inspector, I often encounter older systems that still rely on R-22 refrigerant, a substance that has been phased out due to environmental concerns. Understanding what this means for your potential home can save you from unexpected costs and headaches down the road.

What Is R-22 Refrigerant?

R-22, commonly known as Freon, has been widely used in residential air conditioning systems for decades. However, due to its harmful effects on the ozone layer, the U.S. Environmental Protection Agency (EPA) began phasing it out under the Clean Air Act.

As of January 1, 2020, the production and import of R-22 have been completely banned in the United States. While existing systems can still operate using recycled or reclaimed R-22, the supply is limited—and expensive.

Why This Matters for Homebuyers

If the home you’re considering has an older air conditioning system that uses R-22, there are a few important things to keep in mind:

1. Higher Repair Costs
   If the system develops a refrigerant leak, recharging it with R-22 can be costly due to limited availability. In some cases, the cost of repair may approach or exceed the cost of replacing the entire system.
2. Limited Lifespan
   Most air conditioning systems have a lifespan of 10–15 years. If the unit is already older and uses R-22, it may be nearing the end of its useful life.
3. Replacement Considerations
   Modern systems use more environmentally friendly refrigerants, such as R-410A. Upgrading to a newer unit not only ensures compliance with current regulations but can also improve energy efficiency and reduce utility bills.

What to Expect During a Home Inspection

During a home inspection, we evaluate the air conditioning system for overall condition, approximate age, and performance. If the system appears to use R-22, It will be noted in the report and we will recommend further evaluation by a licensed HVAC professional if needed.

While a home inspection is not a detailed HVAC diagnostic, it provides valuable insight into whether the system may require repair or replacement in the near future.

 

Tips for Buyers and Sellers

For Buyers:

• Ask about the age and maintenance history of the AC system
• Budget for potential replacement if the system uses R-22
• Consider negotiating with the seller if the system is outdated

For Sellers:

• Be upfront about the type and condition of your AC system
• Consider replacing an aging R-22 system before listing your home
• Provide maintenance records to reassure buyers

Air conditioning is essential for comfort during New Jersey’s hot and humid summers. If a home still relies on an outdated R-22 system, it’s important to factor that into your decision-making process. A professional home inspection can help identify potential issues early, giving you the information you need to make a confident investment.
