I worked out of town but my girlfriend, my family, and friends still lived in my hometown. I would try to come regularly to see my girlfriend. Whenever I was around, we would go for dates at the movies, picnic at the park or to eat something in one of the many sprawling restaurants. The movie was amazing just as we expected but the experience at the cinema was not the best. Their air purification system, if they had any, seemed not to be working. I could hear the central air conditioning unit running when we were paying for our ticket. We had come to this cinema so many times but had not noticed this. I struck up a conversation with the manager and was complaining about the state of the cooling products at the cinema. The manager hired me to perform a HVAC tune up on the unit. I suspected their air duct had a leak or the washable filter was filthy. The issue was just as I had thought, however, they were not serious issues. I also upgraded the thermostat to a smart one. The ductwork was clear and clean so there was no need for duct cleaning. The biggest issue was with the air cleaning system, they had not mastered how the unit worked or how to properly maintain it. Even though I knew more about air conditioning than air cleaning, I had offered air purification help to other clients for a long time and my a/c representative was there to confirm all the details. The management was satisfied with our work and so were the customers. They had not serviced the unit since the heat pump instal was done by the then a/c repairman.
