What is an HVAC Actuator?

To put it simply, actuators play a crucial role in controlling the damper in the system. These are powered mechanisms that are designed to regulate the flow of smoke out and fresh air in. Within your HVAC system, the actuators ensure accurate control as required.

How Do You Test an Actuator?

To evaluate an actuator, attach a multimeter to one of the leads and take note of the amperage as the rod extends and retracts. This method is the most accurate for a reading of the actuator’s current consumption.

Is There a Way to Reset an HVAC Actuator?

This process will differ depending on the brand and actuator type. For blend door actuators, simply remove the actuator and turn the climate control to max heat. Then, turn the blend door shaft until you can feel the max heat coming out of the vents. Finally, reinstall the actuator and once everything is back in place, it should be reset.

What are the Symptoms of a Failing HVAC Actuator?

Several indicators may suggest a faulty actuator. Among the most prevalent are tapping noises, knocking noises or irregular airflow. If you notice a decrease in air flow or hear any strange noises, have the HVAC actuator checked.
