  1. What is the primary function of an HVAC system?

    Answer: Control temperature, humidity, and air quality

    HVAC systems regulate heating, ventilation, and air conditioning to maintain indoor comfort and air quality.

  2. Which component is responsible for moving air through a duct system?

    Answer: Blower fan

    Fans or blowers circulate air through HVAC systems to distribute conditioned air throughout a building.

  3. What is the role of a thermostat in HVAC systems?

    Thermostats sense room temperature and signal HVAC equipment to turn on or off to maintain desired conditions.

  4. Which type of HVAC system allows individual control of different building zones?

    Answer: Zoned system

    Zoned HVAC systems divide spaces into areas that can be controlled independently, increasing energy efficiency and comfort.

  5. What does a Variable Air Volume (VAV) system do?

    Answer: Vary airflow based on space requirements

    VAV systems adjust the amount of air delivered to spaces based on cooling or heating needs, improving efficiency.

  6. Which maintenance task improves HVAC system efficiency?
