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, any existing manufacturer's warranty on that system will automatically transfer to the new owner. The new owner will be treated as the original purchaser of the system, and the warranty will remain in effect without any additional fees for the transfer. However, the transfer of the warranty does not extend its remaining term.

Additionally, the bill specifies that the warranty transfer applies only if the sale occurs after October 1, 2025, and the warranty is still active at the time of the sale. It also clarifies that any warranty agreements entered into or renewed before this date will be governed by the previous law. The bill includes new legal language to define key terms such as "HVAC system," "manufacturer's warranty," and "residential real property," while deleting any conflicting provisions from existing law.
