The bill establishes regulations regarding the transfer of unexpired manufacturer's warranties for heating, ventilation, and air-conditioning (HVAC) systems when residential real property is sold. Effective October 1, 2025, if a residential property that includes an HVAC system is conveyed to a new owner, the existing manufacturer's warranty will automatically transfer to the new owner and remain in effect as if they were the original purchaser. The bill defines key terms such as "HVAC system," "manufacturer's warranty," and "residential real property," and specifies that the warranty transfer does not extend the warranty's remaining term.

Additionally, the bill mandates that the warrantor must continue to honor the warranty terms without charging a transfer fee. It clarifies that the provisions apply only to sales occurring on or after the effective date and that any warranty agreements entered into or renewed before this date will be governed by the previous law. The bill aims to enhance consumer protection by ensuring that new homeowners benefit from existing warranties on HVAC systems.
