Hello, I'm EdisonLin27. I wanted to let you know that one or more of your recent contributions to Air conditioning have been undone because they appeared to be promotional. Advertising and using Wikipedia as a "soapbox" are against Wikipedia policy and not permitted; Wikipedia articles should be written objectively, using independent sources, and from a neutral perspective. Take a look at the welcome page to learn more about Wikipedia. Thank you. Edison Lin27 (Message Me! • &#128220; ) 08:29, 6 December 2019 (UTC)
