HVAC stands for Heating, Ventilation, and Air Conditioning. It refers to the systems used to regulate the indoor environment of buildings, ensuring comfort for occupants by controlling temperature, humidity, and air quality. Here’s a breakdown of each component:

1. Heating: This component of the system is responsible for warming up the indoor air during colder seasons. Common heating systems include furnaces, boilers, heat pumps, and electric heaters. They can use various fuels such as natural gas, oil, electricity, or renewable energy sources.

2. Ventilation: Ventilation involves the exchange of indoor air with outdoor air to improve air quality and remove pollutants, odors, moisture, and excess heat. This can be achieved through natural ventilation (using windows, vents, and other openings) or mechanical ventilation (using fans, air ducts, and filters).
