I had owned a heating and a/c shop for a very long time and I was retiring.
There had been very many technological advancements in the heating and a/c units and with my old age, I fell off from keeping up with the rapidly changing technology. Now that I want to retire, I was thinking of turning my shop into a sort of museum for all ancient cooling units. One of the pieces of cooling equipment I had in the shop was the dial-up controller. Currently, there are wireless thermostats in the market and HEPA filters which of course have made the central air conditioning more efficient. Most of the units that end up in my store are the ones that have malfunctioned because of not getting quality AC service over their lifetime. While taking stock, I noticed some of the units I have were from the first inventions until the new HVAC systems such as the zoned HVAC unit. Before I opened my shop, I was a cooling specialist and had worked on numerous units including commercial air conditioning systems. I fixed a lot of units to help with the indoor comfort of all my customers. I was excited about my antique store and knew that even cooling workmen would purchase different components for customers who have older units while doing the annual HVAC service. The residents were excited about this as well as it would be educational and they would get a chance to show their children the first inventions. Currently, there were systems without air ducts which was something phenomenal for me as we have grown up with vented units. I am glad to witness this technology but also proud to uphold ancient technology.
