What are the primary components of an HVAC system?

The primary components of an HVAC system are heating, ventilation, and air conditioning. Each of these components serves a distinct function that is crucial for maintaining a comfortable indoor environment.

Heating refers to systems that provide warmth during colder months, typically using furnaces or heat pumps. Ventilation involves the exchange of indoor air with outdoor air to maintain air quality and control humidity levels, which is critical for health and comfort. Air conditioning is responsible for cooling and dehumidifying indoor air during warmer months, helping to create a comfortable living space.

Understanding these components is essential for anyone involved in building analysis or HVAC system design because they work together to ensure a balanced and efficient indoor climate. This knowledge allows analysts to assess a building's energy efficiency, occupant comfort, and overall performance effectively. Other suggestions like lighting, insulation, and air filtration, while important for building performance, do not represent the fundamental components of an HVAC system.
