We will be happy to help you out..but we (or at least I) will not give you a direct answer. Fist tell us about you, what kind of class is this for. Are you an apprentice or just in schooling? What year? Do you have a good salsa recipe?
HVAC has its own seasons also...think about what happens to make a room comfortable in the summer and in winter. Think about how one would service those systems.

in commercial, work sixty or more hour weeks when it gets hot or cold, down to forty some the rest pf the year. seasonal changes can be described like this......CHING! thats the bell ringing when you cash your check from all of the overtime.
all buildings go on outside air as soon as possible to get the electric loads off there back 55F below you can cool a building mixing OA and returns..then the work begins on the big chillers teardowns,tubes,leak checks,total ripe outs and May comes around fast when the outside air starts to warm up.with the fall temps the other work loads are the shutting down and draining of all towers and piping exposed to freezing temps..so like said seasonal temps change and the OT kicks in to get a jump on equipment and unpredictable repairs required
