The R410a Refrigerant Phase-Out & What it Means for Your HVAC System

As of January 2025, new HVAC units will no longer be using R410a refrigerant to provide cooling services for your home. New units will now feature either R-32 or R454-B refrigerant. As a homeowner, you may have some questions regarding the new EPA regulations on HVAC refrigerants and what it means for you and your home’s unit.

At Tindall & Ranson, we’re here to help answer your questions and provide some insight into the next steps.


Why is R410a Being Phased Out?

In an effort to reduce emissions and work towards a more sustainable way of living, the EPA has made the decision to phase out R410a due to its high levels of hydrofluorocarbons, which are known to have a negative effect on the ozone layer.

This refrigerant shift is in an effort to help optimize efforts on the reduction of our carbon footprint while utilizing more eco-friendly materials while retaining the necessary comfort in our homes.


Do I Need to Replace My Unit if it Uses R410a Refrigerant?

You’ll eventually need to make the shift toward a unit that uses either R-32 or R454-B, but for now, you can keep your current unit running to effectively cool your home during the summer months. These units will continue to be services until the remaining R410a stock has been depleted.


What are the Benefits of R-32 and R454-B?

Both refrigerants aim to be more energy efficient and offer zero effects on the ozone layer. R-32 offers lower toxicity and improved thermal conductivity and refrigeration capacity. R454-B offers more heating efficiency than R-32, and even requires less refrigerant in comparison to R410a.


When Should I Get a New HVAC Unit?

While R410a is no longer being produced as of 2025, you may want to be on the lookout for a new unit that works with the new recommended refrigerants. There’s no immediate rush for a replacement, just know that there’s a finite amount of R410a left, so it’s best to get a head of it and begin the search for your new unit.

New HVAC systems are being designed with the updated refrigerants in mind. Whether you have an old unit that needs to be replaced soon, or you plan on moving into a new home, you’ll want to consider finding an HVAC unit that works with R-32 or R454-B as not all systems are configured for the refrigerant change.
