The 2026 Refrigerant Transition: What It Means for Your Home

The HVAC industry is gearing up for a major nationwide change, and if you’re a homeowner in Bryan, OH or the surrounding Tri‑State region, it’s important to understand how it affects future heating and cooling upgrades. Beginning January 1, 2026, all newly installed residential and light commercial HVAC systems must use low‑GWP (global warming potential) refrigerants. This shift impacts anyone planning AC installation, furnace replacement, or full HVAC system upgrades in the next year.

As a trusted HVAC contractor in Bryan, OH, we want to make sure local homeowners are prepared. Here’s what’s changing, why it’s happening, and how to plan ahead.

Why Are HVAC Refrigerants Changing?

For years, refrigerants like R‑410A have been common in air conditioning and heat pump systems thanks to their reliable performance. However, older refrigerants also have a high global warming potential. Under the EPA’s Technology Transitions Rule—part of the AIM Act—the government is phasing out these high‑GWP refrigerants to encourage more environmentally friendly cooling technologies.

If you’re considering AC installation in Bryan, OH or planning to replace your furnace and air conditioner together, these regulations may influence the equipment available in 2025 and beyond.

What Changes Begin in 2026?

Starting January 1, 2026:

• All newly installed HVAC systems must use low‑GWP refrigerants
• No contractor can install leftover 2025 inventory that uses older refrigerants
• Manufacturers will fully shift to producing A2L‑compatible systems

Your current HVAC system can stay in place, but repairs may become more expensive over time as legacy refrigerants and parts become harder to source. If your air conditioner is struggling or your furnace is nearing the end of its service life, planning ahead may save you money.

What Are A2L Refrigerants?

The new refrigerants replacing R‑410A—such as R‑454B and R‑32—are classified as A2L. These refrigerants offer significantly lower environmental impact while maintaining reliable cooling performance.

A2L refrigerants are mildly flammable, but HVAC systems designed for them include enhanced safety measures such as:

• Specialized leak‑detection sensors
• Improved ventilation designs
• Updated components that meet new building and fire codes

When installed by a licensed HVAC technician, A2L systems are safe, efficient, and compliant with updated regulations.

Energy Efficiency & Cost Considerations

Low‑GWP HVAC systems aren’t just environmentally friendly—they’re also highly efficient. Many new models offer equal or better performance than older units, and because they’re engineered for modern refrigerants, they often deliver:

• Lower energy bills
• More consistent comfort
• Improved humidity control

While upfront system costs may be slightly higher, the long‑term savings and reduced maintenance often outweigh the initial investment. Delaying upgrades could mean paying more later as parts for older systems become scarce.

Can You Retrofit an Existing HVAC System?

Retrofitting an older R‑410A system to use A2L refrigerants is not recommended and usually not possible. These systems operate under different pressures, require different components, and follow different safety standards.

Attempting a retrofit could:

• Void your equipment warranty
• Put you out of code compliance
• Create major safety risks

The safest solution is to replace your system with one designed specifically for low‑GWP refrigerants.

Additional Compliance Requirements

The 2026 transition brings additional regulations, especially for larger HVAC systems. These include stricter leak‑detection and reporting rules and reduced thresholds for repair requirements. While most of these changes affect commercial facilities, homeowners with larger or multi‑unit setups may see expanded requirements in the years ahead.

How Homeowners in Bryan, OH Can Prepare

If your air conditioner or furnace is 10–15 years old—or if you’ve been dealing with repeated HVAC repairs—now is a smart time to explore your options. With high demand expected as 2026 approaches, scheduling AC replacement or furnace installation early can help avoid delays and rising costs.

When choosing an HVAC company in Bryan, OH, look for technicians certified to handle A2L refrigerants. Proper installation is essential for safety, performance, and long‑term reliability.

Don’t forget to ask about:

• Energy efficiency ratings
• Equipment warranties
• Possible rebates or tax incentives
• Low‑GWP refrigerant compatibility

Plan Ahead & Save

The nationwide shift to low‑GWP refrigerants supports long‑term environmental goals and offers real benefits for homeowners who plan early.
