Your HVAC technician used to deliver ice.

600 years of cold, distilled into one lineage.

The job didn't start with refrigerants or thermostats. It started with a cold-cellar keeper packing an underground chamber with straw and snow, hoping the meat would last until August. That was the entire cold-chain — one person, one hole in the ground, one summer.

Then the icehouse workers scaled it up. Then the ice men industrialized it — horse-drawn wagons, city routes, 300-pound block deliveries up four flights of stairs. Ice was perishable inventory. The man hauling it was logistics, quality control, and last-mile delivery in one leather apron.

Mechanical refrigeration ended the ice trade overnight, but the person who understood cold systems — how to move heat, manage pressure, route air — didn't disappear. The title changed. The physics didn't.
