Over the years, my Mom had set up lots of different businesses.
- Unlike other owners, he liked being hands-on.
He’d toil side by side with the staff to learn more about various problems at the establishments. His best success was supermarkets. He had 6 in different parts of the country. Being hands-on meant he traveled a lot to check out the operations, and I went with him. At 1 of the stores, he had lots of toil done on the unit. It was the largest and needed a robust central Heating in addition to A/C to keep it cool while in summer time and moderate in winter. Unlike other ACs, a supermarket heating and cooling device had distinct features. At the door, all of us needed to set up the air curtains system. It would give a blast of air to all customers entering on a tepid summer time afternoon. In winter, the same device would give moderate air. The air curtain had a blower fan inside driven by a small electric motor, and next was the supermarket’s central air ventilation device that served the whole setup. It was more extensive and required ample time to install and do all the ductwork. My Mom preferred to use the rooftop units that had everything the central A/C needed. These rooftop units had a large fan that would drag fresh air from the surrounding into the supermarket… Once the air reached the Heating in addition to A/C system, it went through the air filter. Here all the dirt and dust would remain behind while disinfect air goes into the building. The next part is heating the air using a heat pump or pushing it through a cooling unit. The Heating in addition to A/C operator had to determine the respected action depending on the season. That was important information because I wanted to learn Heating in addition to A/C systems in college and set up an A/C supplier afterward.
