FAQ

What does a transformer do in HVAC?

  • Transformers do not generate power, they transfer power. They can help moderate incoming voltage to reduce or eliminate spikes in power that damage HVAC circuitry. 

What are the different types of transformers?

  • Different types of transformers are used in various types of applications. The main types are power transformer, distribution transformer, autotransformer, isolation transformer, instrument transformer, current transformer and potential transformer.

How do I test a transformer HVAC?

  • The best way to test a transformer is with a multimeter — a device that measures electrical current, voltage and resistance. However, you should only test a transformer if you are comfortable and confident working with electrical equipment. Always remember to remove electrical power from the electrical equipment or appliance and test in a dry area away from children and pets.
