Consumer Notification

Retro-fit Kit Required by California Air Quality Management District

Contact us


All customers that purchased an Ameristar Gas/Electric package unit from Ferguson
will receive three Notification Letters starting April 2022.


After an internal review by The Trane Technologies engineering team, and discussion with the product supplier, they have learned that certain NOx emissions testing, and certification required in certain air quality management districts in the State of California may not have been performed. While this lack of testing and certification does not pose a health or safety hazard to consumers, it is a violation of these air quality management district emissions.


Trane Technologies has the approval from The Air Quality Management District so that we may remediate the affected units with a retrofit kit which will bring the affected units into NOx emission compliance. These kits will include a wire insert that is installed inside each burner tube on the unit’s heat exchanger. There is no cost to the consumer.
