Do You Have to Use R-454B Refrigerant in Garrett, IN?

If you’re a homeowner in Garrett, IN, and you’ve had your air conditioning system serviced recently, you may have heard the name “R-454B” thrown around. Maybe a technician mentioned it during a maintenance appointment, or perhaps you saw it online while researching air conditioning systems. Either way, you’re probably wondering: What exactly is R-454B refrigerant? And more importantly—do you have to use it?

T&T Plumbing & Heating, Inc. breaks it all down in everyday terms so you know exactly how these changes affect your home, your wallet, and your comfort.

What Is R-454B Refrigerant?

R-454B is a newer refrigerant that’s being introduced as a more environmentally friendly alternative to previous refrigerants like R-410A. Refrigerant is the chemical that flows through your air conditioning or heat pump system, absorbing heat from inside your home and releasing it outside to cool warm air.

R-454B is a zeotropic blend of two refrigerant types, R-32 and R-1234yf. It has low toxicity, doesn’t damage the ozone layer like older refrigerants, and is considered a low global warming potential (GWP) refrigerant. It has a GWP of 466, which is significantly lower than R-410A’s GWP of 2,088. That means R-454B refrigerant is less harmful to the environment if it leaks into the atmosphere—a major win for climate-conscious policy and sustainable living.

Why Is R-410A Being Phased Out?

R-410A, which has been the standard refrigerant in residential air conditioners for the last couple of decades, is being phased out as part of an industry-wide shift toward environmentally responsible HVAC solutions.

This change is part of a national regulatory effort driven by the American Innovation and Manufacturing (AIM) Act, passed in 2020. The AIM Act directs the Environmental Protection Agency (EPA) to reduce the production and consumption of high-GWP hydrofluorocarbons (HFCs), including R-410A.

The phaseout started in 2023 and continues to roll out in stages. HVAC manufacturers are now required to begin using lower-GWP refrigerants like R-454B in new equipment. This isn’t just a suggestion—it’s a federal regulation that impacts how HVAC equipment is made and installed across the country, including right here in Garrett, Indiana.

Do You Have to Use R-454B?

Here’s the short answer: If you’re installing a new air conditioner or heat pump system, there’s a good chance it will be designed to use R-454B or another low-GWP refrigerant. But if your current system uses R-410A, you can continue to use and service it without switching refrigerants—at least for now.
Let’s dive into what that means for you as a homeowner:

1. New Systems Are Designed for R-454B

If you’re in the market for a new AC unit or heat pump in 2025 or beyond, the systems available for purchase will likely be engineered to use R-454B or other similar refrigerants. HVAC manufacturers have already begun redesigning equipment to meet federal guidelines. So if you’re replacing an old unit, you’ll be using this new refrigerant by default.

2. Existing R-410A Systems Can Still Be Serviced

If your current HVAC system uses R-410A, you don’t need to panic or rush to upgrade. Technicians at T&T Plumbing & Heating, Inc. can still repair and recharge R-410A systems. However, since R-410A is being phased down, it will become more expensive and harder to find over time.

Think of it like leaded gasoline years ago—it didn’t disappear overnight, but it gradually faded out as the industry shifted to better alternatives that were in compliance with the government phaseout.

3. You Can’t Mix Refrigerants

This is very important: R-454B refrigerant cannot be used in an existing R-410A system. The components, pressures, and safety controls are different, and attempting to swap refrigerants without replacing the system would result in serious damage.

What Does This Mean for Garrett Homeowners?

Let’s talk about how all this affects you locally.

Future-Proofing Your HVAC System

If your HVAC system is more than 10-15 years old and you’re considering a new air conditioning unit soon, you’ll want to talk to your HVAC contractor about R-454B refrigerant options. Choosing a unit that uses this new refrigerant means you’re aligning with current regulations and setting yourself up for long-term savings and availability.

T&T Plumbing & Heating, Inc. can walk you through the pros and cons of each available system and help you make a decision that balances reliable performance, budget, and environmental impact.

Increased Maintenance Costs for R-410A

As R-410A supplies dwindle, the cost to recharge an older system will go up. If your unit is leaking refrigerant or running low, you might find that a repair becomes unexpectedly expensive. That’s why many homeowners are opting for a proactive replacement before problems arise.

If your unit still has some life left, annual maintenance and leak prevention become more critical than ever.

Safety Considerations

It’s worth noting that R-454B refrigerant is classified as “mildly flammable” (ASHRAE safety classification A2L). While this sounds scary at first, it’s not a major concern. Modern HVAC systems are built with safety features and tested rigorously. As long as installation is handled by licensed, experienced professionals—like the techs at T&T Plumbing & Heating, Inc.—you won’t need to worry.
