## Answers:
### 1. How does an HVAC system work?
An HVAC (heating, ventilation, and air conditioning) system works by controlling the temperature, humidity, and air quality in a building to create a comfortable environment for its occupants. It does this by taking in outside air, conditioning it to the desired temperature, and then distributing it throughout the building.
### 2. What are the main components of an HVAC system?
The main components of an HVAC system include:
- Furnace: heats air and distributes it throughout the building.
- Air conditioner: cools air and removes humidity.
- Thermostat: controls the temperature inside the building.
- Ductwork: distributes conditioned air throughout the building.
- Ventilation system: brings in fresh air from outside and removes stale air from inside.
- Filters: clean the air by removing dust, pollen, and other particles.
### 3. What is the role of each component in an HVAC system?
- Furnace: heats air using a fuel source such as gas or electricity, then circulates it through the ductwork to warm up the building.
- Air conditioner: cools air by passing it over refrigerant-filled coils, removing heat and humidity in the process, and then distributes the cooled air throughout the building.
- Thermostat: serves as the control center for the HVAC system, allowing users to set the desired temperature and regulate the operation of the furnace and air conditioner.
- Ductwork: a network of tubes that distributes conditioned air from the furnace and air conditioner to different rooms in the building.
- Ventilation system: brings in fresh air from outside and removes stale air from inside, helping to maintain healthy indoor air quality.
- Filters: capture dust, pollen, and other particles from the air, improving indoor air quality and protecting the HVAC system from damage.
