So, you’re a ‘hot shot’ service technition ready to get your hvac master/contractor license. Whoa! slow down for a second. When is the last time you calculated the adjusted friction rate for a duct system, or determined the CFM of combustion air required for a mechanical room, or, determined the free area of a wooden louver. Can you determine the btuh output of a furnace if you know the temperature rise and fan cfm? These are just a sample of the things you will need to know if you expect to pass your mechancal exam. You see, the state doesn’t care if you know how to service a furnace. It wants to be sure you can install a safe system. Therefore, you will need to know how to size ductwork, how to size hvac equipment, how to size gas piping and venting, how to calculate combustion air requirements, all of which effect the operation and safety of the system.
