Both of us have Heating as well as A/C units that play songs plus can talk. My Heating as well as A/C contractor friends plus I were laboring in our lab a single day trying to figure out what would make our modern multi split air conditioning system better! Both of us wanted a cooling machine that was a step above the average a/c unit. Both of us started brainstorming when our radio that was in our Heating as well as A/C lab quit laboring. Both of us didn’t want to work on heating plus cooling units without any background songs. That’s when I got an idea. Both of us decided to try installing a radio into a central air conditioning system so that it could play songs while cooling down a home. The goal was to turn the air ducts into speakers that way the songs would resound in every room that had an air duct in it. Both of us began developing our special central air conditioning machine with the radio on a cool summer time evening, plus finished it in mid winter. Both of us tested the central air conditioning system at my home, where I had only had a window air conditioning system to keep me cool in the summer. Both of us installed the central air conditioning system plus then connected it to my smart control unit.then, using the control unit, both of us were able to make the air conditioning system play songs through every air duct in the house! After thinking about what both of us could do to make it better, both of us decided it would be best if both of us made a special smart control machine that was made to connect to the speaker in the central air conditioning system. Both of us finally finished the smart control machine plus decided it was ready to be sold at heating plus cooling companies.
