Heating refers to the process of raising the temperature of a space for warmth, while ventilation involves the exchange of air to help maintain indoor air quality by removing excess moisture, odors, and contaminants. Air conditioning refers to the cooling aspect, which helps to lower the temperature and manage humidity levels within a space.

Understanding this acronym is crucial for professionals in the gas fitting and HVAC fields, as these systems are often interrelated, influencing how gas appliances, such as furnaces and water heaters, operate in conjunction with these climate control technologies. The accuracy of the term underscores the importance of knowing the full scope of services and responsibilities within the field, from installation to troubleshooting and maintenance of these systems.
