Average Reviews:
(More customer reviews)I have a six zone HVAC system in my home and this is the forth Honeywell zone damper actuator to fail in the six years of system operation. When you open it up and take a look at how it's design/constructed you'll understand why they don't last. Real garbage! I should have specified commercial level equipement. I would have saved money and agrevation in the long run.
