Long Island HVAC Owners Face Critical Decisions as 2025 Building Code Changes Reshape Repair vs. Upgrade Strategies
Long Island property owners are navigating a complex landscape of new building code requirements that took effect in 2025, fundamentally changing how they approach HVAC repair and upgrade decisions. These changes include prohibitions on fossil-fuel equipment installations in new buildings starting December 31, 2025, and restrictions on refrigerants with high Global Warming Potential (GWP).
The New York State Building Code Revolution
New York’s Department of Environmental Conservation adopted amended Part 494 regulations in January 2025, establishing prohibition deadlines in 2025, 2030, 2033, and 2040 for various refrigerants based on their GWP ratings. The EPA is phasing out R-410A refrigerant in 2025, with production and import of R-410A for new equipment banned starting in 2025.
For Long Island homeowners and businesses, this means existing HVAC systems using older refrigerants can continue operating, but while servicing with R-410A will still be possible for a limited time, availability and cost are expected to change as production decreases and reclaimed refrigerant becomes critical for maintaining older systems.
Impact on Repair vs. Replacement Decisions
The regulatory changes are forcing property owners to reconsider the traditional repair-versus-replace calculation. Building codes and standards evolve, and older systems may not comply with current requirements for energy efficiency and environmental impact, with upgrading to newer systems ensuring compliance and improving building marketability and value.
R-410 refrigerant will continue to be produced until 2034, steadily decreasing to about 20% of today’s production quantities, meaning property owners will be able to get R-410 for current systems for the life of those systems. However, as seen with previous refrigerant phase-outs like R-22, prices have risen significantly, and the same is expected with the R-410 phase-out.
New Refrigerant Requirements and Equipment Costs
The new industry standard refrigerant replacing R-410A is R-454B, designed to have lower global warming potential while performing similarly. However, there are cost implications. R-454B is slightly flammable, requiring equipment to include additional safety components, making new equipment about 25% more expensive.
R-454B is an HFC and hydro-fluoro olefin blend with superior cooling capacity and 78% lower GWP than R-410A, but these new low-GWP alternatives come with flammability risks classified as A2L (mildly flammable), requiring updates to standards and building codes for safe installation.
Strategic Timing Considerations
The timing of these changes creates unique opportunities and challenges. Before regulations took effect on January 1, 2025, customers could take advantage of current equipment prices before they increased 25%, and since R-410 refrigerant and replacement parts will be available for the life of the system, they could get the most energy-efficient equipment at the best price.
Equipment manufactured before January 1, 2025, can be installed until January 1, 2026, with buildings having permits that include R-410A having until January 1, 2027 to complete installation, charging, and startup.

Making the Right Decision
When deciding between repairing an existing HVAC system and replacing it with a new, more efficient unit, it’s vital to consider immediate repair costs versus long-term savings, evaluating how energy efficiency of new units could lead to lower monthly bills compared to ongoing expenses of maintaining older, less efficient systems.
The 2025 building code changes represent more than regulatory compliance—they’re reshaping the economics of HVAC ownership on Long Island. Property owners who understand these changes and work with knowledgeable local contractors will be best positioned to make cost-effective decisions that ensure comfort, compliance, and long-term value.
