A2L Refrigerants: What Homeowners & Businesses Need to Know.

What Are A2L Refrigerants?

• The HVAC industry is transitioning to A2L refrigerants, a new generation of environmentally friendly refrigerants replacing R-410A. This change is driven by federal regulations aimed at reducing greenhouse gas emissions and improving energy efficiency.

• A2L refrigerants, such as R-32 and R-454B, have a lower global warming potential (GWP) and offer better cooling efficiency while being classified as mildly flammable.

How Does the A2L Refrigerant Transition Affect You?

1. Increased Energy Efficiency

New A2L refrigerants enhance HVAC system performance, potentially leading to lower energy bills for homeowners and businesses.

2. Lower Environmental Impact

A2L refrigerants have a significantly lower carbon footprint, helping homes and businesses stay compliant with eco-friendly HVAC regulations.

3. HVAC Equipment Compatibility

Older R-410A systems are NOT compatible with A2L refrigerants. If you need a replacement, you’ll require a new system designed for A2L refrigerants.

Retrofitting is not an option, so upgrading to a new, A2L-ready HVAC system will be necessary.

4. Potential Cost Increases

New HVAC systems designed for A2L refrigerants may have higher initial costs due to updated safety standards and new system designs.

As R-410A is phased out, repair costs for older systems will increase due to the rising price and limited availability of R-410A refrigerant.

5. New HVAC Tools & Equipment Are Required

A2L refrigerants require specialized tools and equipment for safe installation and servicing, including:

A2L-rated vacuum pumps & gauges

Leak detectors for mildly flammable refrigerants

A2L-specific recovery machines & tanks

Flare and brazing tools adapted for A2L-safe connections

6. WARD HEATING & AIR is A2L-Ready!

Our team has already invested in all necessary A2L-compatible tools and training, ensuring safe and efficient HVAC installations and repairs.

7. Regulatory Compliance & Safety

All new HVAC systems using A2L refrigerants meet the latest safety standards. While A2L refrigerants are classified as mildly flammable, professional installation and maintenance ensure they are safe to use in homes and businesses.

What Should You Do?

✅ If your current HVAC system is running smoothly, there’s no urgent need to replace it.

✅ If you’re planning an upgrade, new HVAC units will use A2L refrigerants starting in 2025.

✅ Work with a certified HVAC contractor like WARD HEATING & AIR to ensure proper installation, safety, and compliance.

✅ Be prepared for potential price changes as the transition to A2L refrigerants progresses.
