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

If you’ve been hearing buzz about R-454B refrigerant and wondering whether it affects your air conditioning system in Kendallville, IN, you’re not alone. Many homeowners are beginning to ask important questions about this new refrigerant, especially when it comes to air conditioning maintenance in Kendallville, IN.

At T&T Plumbing & Heating, Inc., we believe in keeping our customers informed—so let’s break down what you really need to know.

Understanding R-454B: What Is It?

R-454B is a newer refrigerant being introduced as part of an industry-wide transition away from high global warming potential (GWP) refrigerants, like R-410A. It’s a zeotropic blend designed to have a significantly lower environmental impact and lower global warming potential. R-454B has a GWP of around 466, which is a big step down from R-410A’s GWP of approximately 2,088.

Manufacturers and environmental agencies alike are shifting toward more eco-friendly alternatives in response to both national and global regulations aimed at reducing greenhouse gas emissions. But that doesn’t mean homeowners are being forced to make immediate changes.

What Are the Regulations?

The U.S. Environmental Protection Agency (EPA) is phasing down the production and import of hydrofluorocarbon (HFC) refrigerants under the American Innovation and Manufacturing (AIM) Act. This includes high-GWP options like R-410A. The AIM Act doesn’t outright ban the use of R-410A, but it does limit its availability over time, which will likely lead to higher costs and reduced availability of older refrigerants.

So what does that mean for Kendallville homeowners?

While there is no current law that mandates homeowners must switch to R-454B refrigerant or replace their existing R-410A systems, new AC units and heat pumps manufactured from 2025 cannot use previous refrigerants like R-410A, and must use refrigerants with a lower global warming potential. This shift affects new installations and equipment replacements due to the EPA rules regarding newly manufactured HVAC systems, but not necessarily your current unit.

Do I Have to Use R-454B Refrigerant in Kendallville?

In short: not yet, and not unless you’re replacing your air conditioner.

If your existing air conditioner is still running on R-410A, you can continue to use and service it. However, if your system breaks down and requires a full replacement, it’s very likely that the new unit will use R-454B or another low-GWP refrigerant, depending on the brand and model.

What About Older Units? Are They Compatible?

Here’s an important distinction: R-454B is not a drop-in replacement for R-410A.

If you have an R-410A system, you can’t simply switch to R-454B refrigerant during a routine maintenance visit or repair. These refrigerants operate under different pressures and have different chemical properties. Attempting to use R-454B in an R-410A system could damage the components and void your warranty.

Compatibility is a critical issue:

  • Compressors and coils designed for R-410A are not suitable for R-454B.
  • Lubricants used in the system may not be compatible with R-454B.
  • Expansion valves and metering devices must be correctly calibrated for the refrigerant’s specific characteristics.

If your current system is in good working order, routine maintenance and repairs can continue with R-410A for now. However, be aware that service costs may rise as R-410A becomes scarcer.

How Does This Impact Air Conditioning Maintenance?

Even though the refrigerant transition doesn’t force you to replace your AC system immediately, it does make regular maintenance more important than ever.

If your AC is still running on R-410A, you’ll want to keep it in peak condition to avoid costly repairs or an untimely system failure. Air conditioning maintenance in Kendallville, IN, from T&T Plumbing & Heating, Inc. includes:

  • Checking refrigerant levels and pressure.
  • Inspecting for leaks and ensuring system integrity.
  • Cleaning coils and air filters.
  • Lubricating moving parts.
  • Testing thermostat operation and electrical connections.

By scheduling annual AC tune ups, you can extend the life of your system and avoid the early expense of transitioning to a new refrigerant platform.

When Should You Consider Replacing Your System?

If your current unit is more than 10–15 years old or has needed frequent repairs, now is a smart time to start planning your replacement strategy. Choosing a system that uses R-454B refrigerant will future-proof your home cooling setup.

At T&T Plumbing & Heating, Inc., we can walk you through:

  • The benefits of newer, more efficient air conditioners and heat pumps.
  • Which models are designed for R-454B.
  • What rebates or tax incentives may be available.
  • Long-term energy savings vs. upfront costs.

Many of the latest air conditioning systems not only use R-454B but also offer better energy efficiency, reliable performance to cool warm air, quieter operation, and improved humidity control.

Safety and R-454B

While it is considered low toxicity and does not harm the ozone layer, R-454B refrigerant is classified as A2L, which means it is mildly flammable. This has prompted updates to safety standards and installation protocols. As a result, only licensed HVAC professionals—like the team at T&T Plumbing & Heating, Inc.—should handle, install, or service equipment using R-454B.

We follow all updated safety codes and ensure that your new equipment is installed to meet or exceed local building codes and manufacturer guidelines.

What Should Kendallville Homeowners Do Now?

While you don’t have to switch to R-454B in Kendallville yet, the industry is moving in that direction.

Here’s what we recommend:

  • If your AC is working fine, continue regular maintenance to keep it going strong.
  • If you’re planning a replacement, consider R-454B-compatible units to align with future regulations.
  • Stay informed, especially as refrigerant costs and availability may change in the coming years.
  • Work with a trusted HVAC contractor, like T&T Plumbing & Heating, Inc., to ensure you get honest guidance and proper installation when it’s time for replacement.
