The Ecovent system is an accessory to your HVAC system, and therefore does not affect the warranty of the HVAC equipment. When correctly installed, the sensors, vents and smart hub will operate the HVAC equipment and balance the system dynamics to keep the home safe and comfortable. By constantly monitoring the HVAC equipment, Ecovent can notify the user through the app if the system is not working correctly, or is operating outside of performance tolerance.
