How many coils are in a HVAC system?

In a typical HVAC system, there are generally two main coils:

Evaporator coil: This coil is located in the indoor unit and is responsible for absorbing heat from the indoor air. It helps to cool the air.

Condenser coil: Found in the outdoor unit, this coil releases the heat that the system has absorbed to the outside environment. It is crucial for the heat rejection process.

However, in some more complex systems or in certain applications, there may be additional coils or specialized coils for specific functions. For instance, there could be a reheat coil in some systems to provide additional heating in certain situations. The specific number and types of coils can vary depending on the design and requirements of the particular HVAC setup.
