What is the role of an HVAC system in environment control?

An HVAC (Heating, Ventilation, and Air Conditioning) system plays a crucial role in environmental control by regulating indoor temperature, humidity, and air quality. It provides heating during cold weather, cooling during hot weather, and ensures proper ventilation to eliminate stale air and introduce fresh air. By maintaining these conditions, HVAC systems enhance comfort, promote health, and improve energy efficiency in residential and commercial spaces. Additionally, they can help in controlling airborne pollutants and allergens, contributing to a healthier indoor environment.
