Understanding the Shift: R-454B vs R-410A in HVAC Units

If you’re shopping for a new HVAC system, you’ve likely heard about the industry shift from R-410A to R-454B refrigerant. But what does this mean for your timing, budget, and ability to stay cool, especially with summer temps heating up?

At Buckley, our mission is simple: Keep you comfortable, no matter what system you choose.

Let’s break it down…

R-454B vs R-410A: What’s the Real Difference?

The move from R-410A to R-454B is driven by environmental regulations. R-454B offers a 78% lower Global Warming Potential (GWP) compared to R-410A, making it a greener, more sustainable option.

However, while R-454B is better for the planet, its adoption isn’t without complications:

• R-454B systems are more expensive upfront
• Supply chain challenges and fitting compatibility issues are causing delays
• Many contractors can't fully charge R-454B systems yet

Why? Two major reasons:

1. Limited refrigerant availability – The market hasn’t caught up to demand.
2. New charging fittings – Traditional tools don’t work with the updated left-turn fittings on R-454B units.

So even if you install a brand-new unit, you may be stuck waiting weeks or even months before it can blow cold air. And no one wants to be left sweating it out when the heat hits hard.

Buckley’s Advantage: We’re Ahead of the Curve

While others scramble to find parts and refrigerant, Buckley has already stocked up on R-410A and R-454B systems, the refrigerant, and the tools to charge them. That means when your unit gets installed, it will be fully charged and ready to cool immediately.

Whichever path you choose, we have the solution:

Looking to save money without compromising comfort? R-410A systems are still available and more affordable upfront. At Buckley, we can install and fully charge your unit immediately without delays.

Want to go green? We have R-454B refrigerant and specialty fittings, so your new system can be installed and fully charged without delays.

Need a repair or maintenance? Our techs arrive with all necessary parts on the truck.

Still deciding?  We’ll help you compare your options and choose what works best for your budget, timeline, and long-term goals.

Should You Upgrade Now or Wait?

Many homeowners are asking:

• “Should I wait until R-454B systems are more common?”
• “Will I still be able to repair my current system in a few years?”
• “Is it safe to buy a R-410A unit today?”

Here’s our honest take:

R-410A units are still a solid choice, and we can install and service them for years. If you need an affordable and efficient system now, this is a great option.

R-454B units are future-forward and great if you prioritize sustainability and can invest a bit more upfront. Just ensure you’re working with a contractor who can install and charge them appropriately.

What you don’t want is to buy a new system and then wait months for the refrigerant or the right tools to show up. Sadly, that’s happening all too often with less-prepared providers.
