“Texas continues to demonstrate its commitment to protecting public health and safety through the adoption of modern, science-based codes,” said Christina Kaeini, IAPMO senior director of Government Relations. “The 2024 Uniform Mechanical Code incorporates critical updates that address evolving technologies, indoor air quality, ventilation performance, and refrigerant safety while providing clear, enforceable requirements for the mechanical industry.”

Among the significant updates included in the 2024 UMC are enhanced air filtration requirements, new ventilation system balancing provisions, updated refrigerant safety classifications, and requirements addressing the use of emerging low-global-warming-potential refrigerants. The code also includes new provisions supporting modern mechanical system design and installation practices. 

Texas has a long history of adopting nationally recognized construction and safety codes that provide consistency for the regulated community while supporting innovation and economic growth. The adoption of the 2024 UMC helps ensure that HVAC and refrigeration professionals across the state will be working under up-to-date standards reflecting current industry best practices. 

IAPMO extends its appreciation to the Texas Department of Licensing and Regulation, the Texas Commission of Licensing and Regulation, industry stakeholders, and code officials who participated in the rulemaking process and contributed to advancing safe and sustainable mechanical systems throughout the state.
