For some reason, I never considered the ice cream parlors would want to have A/C too, but that is absolutely a key component in how they keep the ice cream cold and not melty. I currently work after school at a curte ice cream venue downtown. The owner is super nice and obviously used to make the ice cream in his garage, but air conditioning is pumped into the cases of ice cream, which keeps their internal temperature at a cool 38 degrees. I needed to check in each shift, and make sure that all of the A/C units were now working, otherwise it would mean disaster. We had a total of 5 large A/C units in our store, all of which required specific points of care, and required an HVAC serviceman to service them almost every two weeks. The HVAC serviceman will come and oil all the wheels, ensure all the cranks and innards of the A/C units were all now working to full capacity, and replace anything that wasn’t. This is one of the major keys to our success, as this plan allows us to keep the ice cream at a good temperature,and keeps the store nice and cold in the summer season. The Winters can be a bit rough, as the air condition competes with the cold air outside. Investing in a good pair of gloves is a good rule of thumb when working in A/C, although I also wear a hat and scarf tied tightly around my neck, which is really a blessing in disguise. In the warm seasons, I am used to the air conditioning temperature by then, and am able to only wear a shirt and a pair of jeans when in the A/C weather conditions.
