What is all this HVAC refrigerant hype? And what do you need to know as a Northern Chicagoland homeowner to stay in the know?

By now, you may or may not have heard the buzz around the HVAC industry. The industry is undergoing a significant shift toward environmentally friendly refrigerants with lower Global Warming Potential (GWP). At Duane Blanton Plumbing, Sewer, Heating & Cooling, we want you to understand what this means for you as a homeowner and loyal customer. This transition is mandated by the American Innovation and Manufacturing (AIM) Act of 2020, which aims to phase down hydrofluorocarbons (HFCs) in favor of A2L refrigerants—a new class of refrigerants designed to reduce environmental impact.

Technically speaking, this is a program designed to help the environment, but it all funnels down to you, the consumer.

In this blog, we’ll discuss the timeline for the transition, the benefits of these new refrigerants, and what our customers need to know before upgrading or replacing their HVAC systems.

Here’s what you need to know:

  • The transition officially began January 1, 2025, when HVAC manufacturers were required to stop producing new equipment that uses high-GWP refrigerants like R-410A.
  • Newly manufactured HVAC systems will use lower-GWP alternatives. Here at Duane Blanton, our partners at Carrier are upgrading their refrigerant to R-454B.
  • While your existing systems can still be serviced with R-410A, its production will gradually decrease, making it more expensive over time.

What Are the Benefits of the New Refrigerants?

  • Lower Environmental Impact – A2L refrigerants significantly reduce greenhouse gas emissions.
  • Increased Energy Efficiency – These refrigerants improve system performance, reducing electricity consumption and utility bills.
  • Long-Term Availability – As R-410A is phased out, systems using A2Ls will be more cost-effective to maintain.
  • Compliance with Regulations – New refrigerants align with future federal and state environmental policies, making them a smart investment.

Replace or to Repair your current system…that is the question….

First thing is first. Here are the key things to consider:

  • Know Your System’s Refrigerant – If your unit runs on R-410A, consider your long-term maintenance costs.
  • Plan for Future Replacement – If your system is over 10 years old, replacing it with an A2L-compatible unit may be more cost-effective than repairs.
  • Talk to an HVAC Professional – Duane Blanton’s HVAC contractors can help you choose the right system for your home and ensure safe installation.
  • Stay Informed – Keep an eye on refrigerant phase-out updates and Michigan HVAC rebates.

Thinking about AC Replacement?

Here are a few good reasons why this option is for your Northern Chicagoland family:

  • Future-Proofing – You won’t have to worry about refrigerant availability or increasing costs of R-410A.
  • Higher Efficiency –Better performance and lower energy bills.
  • Potential Incentives – Some local or federal incentives may be available for eco-friendly HVAC upgrades.
  • Avoid Price Increases – As demand for the new refrigerant rises and supply decreases, repair costs for older units may spike.

What’s the Best Option?

  • Repair if:
    • Your system is under 10 years old and in good condition.
    • The repair cost is minor and R-410A is still available.
    • You plan to replace your system in the next few years.
  • Replace if:
    • Your system is over 10 years old.
    • Repairs exceed 30-50% of the cost of a new unit.
    • ou want to upgrade to an A2L-compatible, energy-efficient system.

    Does This Affect HVAC Pricing?

    Yes. With the phase-out of R-410A, expect higher refrigerant costs for older units and increased prices for new HVAC systems as manufacturers transition to new technology. However it is not all bad news, energy savings and efficiency gains from A2L refrigerants can help offset initial costs.

    What to walk away knowing:

    The HVAC industry’s transition to low-GWP refrigerants is a necessary step toward sustainability, efficiency, and regulatory compliance. Homeowners should be aware of these changes and plan accordingly, whether through maintenance, system upgrades, or purchasing a new unit with an A2L refrigerant.

    If you’re considering an AC replacement, now is the time to consult a professional and make a future-proof investment for your home.
