Understanding the 2026 Refrigerant Changes for Home AC Systems

Even if you’re not planning an AC replacement this year, the new 2026 HVAC refrigerant regulations for McKinney, Texas homeowners could affect you. That’s because the regulations will reduce the availability of R-410A, a common refrigerant. They’ll also change how new air conditioning systems are produced.

Learn more about the practical effects of these regulations.

Know the Deadlines That Will Affect You

Until January 1, 2025, manufacturers were still allowed to produce R-410A systems. Now, however, the grace period for installing these systems has ended.

As of January 1, 2026, homeowners can only install systems that use newer refrigerant types. These models have lower global warming potential (GWP) ratios. The new 2026 HVAC refrigerant regulations for Texas homeowners require HVAC systems to use R-454B or R-32 refrigerant.

Do these regulations mean that you must replace your older air conditioner right away? Not necessarily. As long as the unit remains in good operating condition, you can still use it to cool your home.

However, you may need to plan for a replacement earlier than you had hoped. If your system develops a leak, your HVAC technician might find it difficult to find R-410A refrigerant to replace the lost fluid. That’s because production of R-410A has already diminished by 40%, and it will become even rarer over time.

Learn About the Key Benefits of New AC Refrigerants

Switching to a system that uses R-454B or R-32 offers a variety of benefits. One advantage is that these products are much better for the environment. A modern heat pump or air conditioner will also improve energy efficiency by up to 10% overall.

Newer models offer better leak detection technology to minimize exposure to hazardous refrigerants. And while low-GWP refrigerants are mildly flammable, high-efficiency models have improved ventilation to reduce the risk of fire.
