I got a call from one of my commercial HVAC customers, but it wasn’t about a problem with the feeding or cooling system. The customer and owner of the ice cream shop called me because there was a problem with the refrigeration unit. She called the company that regularly handles all of the work on the refrigeration units, but they did not have anyone in the area that day and could not help until the next morning. The owner wondered if I would be able to serve the refrigeration unit. I was happy to go to the commercial business so I could look at the problem. I honestly thought that it was going to be an issue that I could fix, but I didn’t want to tell the customer yes just in case it was something very complicated and outside of my comfort zone. I handle refrigeration problems all of the time, but most of the larger commercial systems require a certified technician or contractor with more knowledge in the commercial refrigeration services. When I arrived at the ice cream shop, I found the place closed down even though it was already after 9:00 a.m. The owner of the business could not open for the day due to the fact that all of the groceries were completely frozen. The refrigeration unit froze everything inside of the machine instead of just keeping things chilled. She had to replace several items before she could open for business. I took a good look at all of the refrigeration equipment and the issue was a simple thermostat problem.
