HVAC stands for Heating, Ventilation, and Air Conditioning. This acronym encapsulates the three primary functions of the system, which are integral to maintaining comfort in residential and commercial buildings.

Heating is crucial for providing warmth during colder months, ensuring that indoor spaces remain livable. Ventilation refers to the process of exchanging or replacing air in a space to improve air quality by removing moisture, odors, and contaminants. Air Conditioning is essential for cooling and dehumidifying the air, contributing to comfort during warm weather.

Understanding the components of HVAC is key not only for installation practices but also for system maintenance and troubleshooting. The other options contain terms that may be related to HVAC but do not accurately represent the full scope of what HVAC entails, leading to misunderstandings about the system's capabilities and functions.
