What the Refrigerant Transition Means for Your Next AC Repair, Replacement or Warranty Claim
Have you ever considered the type of refrigerant your air conditioning system uses?
Chances are, you haven’t. Most individuals are primarily concerned with whether their AC is effectively cooling, dehumidifying, and filtering the air in their homes, as well as the associated costs. However, it is crucial to be aware that the U.S. Environmental Protection Agency (EPA) implemented new regulations last year regarding the chemicals permitted in heating, ventilation, and air conditioning (HVAC) systems.
You may not need to replace your current systems, but the changes could impact your maintenance expenses depending on the type of AC you own. Here is what you should know.
Understanding the 2025 HVAC refrigerant transition
For years, HVAC systems have utilized hydrofluorocarbons (HFCs) as refrigerants and greenhouse gases. However, the American Innovation and Manufacturing Act of 2020 instructed the EPA to phase out the production and consumption of HFCs due to their high global warming potential (GWP). This led to the HVAC industry increasingly manufacturing new air conditioners and heat pumps using A2L refrigerants with lower GWPs, such as R-454B and R-32.
The older refrigerant being phased out is R-410A, which is still present in millions of HVAC systems nationwide. The EPA recently issued a rule in May allowing the installation of systems using R-410A until the existing supply is exhausted. The deadline for reducing HFC usage is 2036, but many manufacturers are already transitioning to meet the standards.
Implications for HVAC systems using R-410A
If your current system utilizes R-410A refrigerant, there is no immediate need to replace it. HVAC contractors can still service these systems.
R-410A refrigerant typically costs between $40 and $75 per pound, according to Angi, an online marketplace for home services. Additional refrigerant is usually unnecessary unless there is a leak. Repair costs for leaks can range from $100 to $250 per hour. It is important to note that handling refrigerants requires EPA certification, so homeowners cannot perform these repairs themselves.
As the supply of R-410A diminishes over time, repair costs for older systems may increase. While sticking with your current unit might still be financially viable, be prepared for higher expenses if repairs are needed.
Considerations when purchasing a new AC system
New AC units typically come equipped with R-454B or R-32 refrigerants. These refrigerants require specialized equipment designed for their use, including updated safety and performance standards. However, this transition is becoming the new industry norm, alleviating concerns for consumers during the shopping process.
While the shift to new refrigerants may not significantly impact your AC selection, it aligns with a broader industry trend towards more energy-efficient equipment.
Joey Dooley, a general manager at ARS/Rescue Rooter in Texas with 23 years of HVAC experience, emphasizes the technological advancements in modern systems. He highlights the availability of communicating systems, variable-speed compressors, and precise capacity control, offering improved efficiency and comfort for homeowners.
Understanding your warranty amidst the transition
New AC units typically include warranties to cover system defects post-installation. These warranties may encompass internal malfunctions and installation errors, regardless of industry transitions like the refrigerant change. However, warranty coverage varies by manufacturer and product, necessitating a thorough review of terms, registration requirements, provisions, and exclusions to ensure comprehensive protection.
