I wanted to send a note to commend you on an excellent article. Refrigerant transition is something that people want to resist as long as possible. However, after reading your article, perhaps they will change their mind. I utilize The ACHR NEWS as a teaching tool. All of the students love to read about the advancements in technology. As an assignment, I have them pick out an article like “Frostlines” and have them tell me what they learned. Your newspaper continues to be a great addition to my classroom. Keep up the good work.
