Many homeowners are unaware that the EPA has been updating refrigerant regulations for air conditioning systems, and these changes will eventually impact the cost and repairability of older HVAC units.
For many years, air conditioners commonly used hydrochlorofluorocarbons (HCFCs) as refrigerants, such as R-22 (HCFC-22, often branded as Freon). Due to impacts to the ozone layer, the EPA officially phased out the production and import of R-22 in 2010.
More recently, the industry has also began transitioning away from all HCFCs due to their high global warming potentials (GWP). Beginning in 2025, newly manufactured residential HVAC systems are required to use lower GWP refrigerants, such as R-454B and R-32. These refrigerants are not interchangeable in previous systems, as mechanical changes are required.
What does this mean for homeowners?
If your air conditioner currently uses, R-22 (HCFC-22), R-142b (HCFC-142b), or R-410A, your system is on a path to obsolescence. It does not necessarily mean your system must be replaced immediately. Existing systems can still be serviced in many cases, including refrigerant replacement. However, as refrigerants and replacement parts for obsolete systems become scarcer, at some point replacement will be necessary.
This is especially important for homeowners with aging HVAC systems. Eventually, many older units may reach a point where repairs are either no longer practical or cost-effective. Planning ahead and budgeting for a future replacement can help avoid unexpected surprises to your finances.
Some homeowners also choose to explore home warranty options that may help offset portions of future repair or replacement costs, depending on coverage and eligibility.
