I work for Trane Commercial HVAC in Clarksville, TN as a manufacturing engineer. I overheard management discussing possible shortages of materials and products due to coming Mexico Shutdown of all businesses outside of medical and food production. Trane Commercial makes large HVAC units for Hospitals and Government facilities including server rooms and the like so we are essential. By my estimation 40% or greater of our components come from or thru Mexico. This Mexico Shutdown will also have an impact on other US manufacturing industries as they rely heavily on Mexico for parts and components for their products. God bless the Bear Nation during this troublesome time.
