What is the primary function of a transformer in an HVAC system?

• A. To regulate temperature levels
• B. To increase or decrease voltage levels in alternating current circuits
• C. To filter impurities from the air
• D. To provide backup power during outages

Answer: (B)

The primary function of a transformer in an HVAC system is indeed to increase or decrease voltage levels in alternating current circuits. This function is crucial because many HVAC components, such as motors and control boards, operate at different voltage levels. A transformer allows for the safe and efficient operation of these components by stepping up voltage for better power transmission over long distances or stepping down voltage to levels that equipment can utilize safely. For instance, a typical HVAC system might use a transformer to convert the higher voltage from the electrical supply down to a lower voltage that the thermostats and control circuits require. This ensures that equipment operates effectively without the risk of damage from excessive voltage, thereby enhancing reliability and longevity in the system's operation.
