When our son decided that he wanted to play the trombone, I thought it was great that he wanted to play an instrument. I had to talk to him about it though because I wanted to make sure that he was extreme about the commitment to this new instrument. I didn’t want to purchase this high-priced instrument if he was never going to play the thing! He promised that he would be committed. When he was practicing his instrument in his room, it was loud, but he started to improve tremendously with his practice; Eventually he asked if he could have a window air conditioner unit in his study room because he said he was always feeling boiling when he was practicing. I thought it would be a shame to block the view from his study room window with a window air conditioner unit, so I decided to call up the Heating, Ventilation plus A/C dealer to see what chances there were for getting more air conditioner up there. I was told about Heating, Ventilation plus A/C zone control & how that would allow the apartment to be divided into weird zones with separate temperature controls for customized temperature control. I figured that our son would appreciate this & I thought it was great that he wouldn’t lose the view from his study room window also. So both of us had the Heating, Ventilation plus A/C zone control update & both of us had a seperate temperature control in our son’s room for him to adjust. He has been cranking the air conditioner while practicing & truthfully, it seems to have improved his playing ability; Both of us were so happy when both of us went to his first performance & he did so well. Both of us recorded the whole performance & both of us have been bragging to our family & friends about our son’s incredible rock n roll talent.
