1.) Does drywall need to be removed to install a damper system?
No. Our dampers have been designed specifically for applications where the ductwork has been buried and is not easily accessible. Check out our products page to find out more about our special application dampers such as the EZYFIT or INSERTA. All dampers come with a lifetime warranty. HVAC pros can register here for videos showing how easy Arzel dampers are to install.
2.) Not enough air coming through the registers?
Check the furnace manual on what the maximum static allowance is for the furnace. Then, adjust the system to run near the maximum static on the smallest zone without creating disturbing air noise for the homeowner. The maximum TSP could be as much as 0.8” to 1.0” W.C. and will have a much greater effect on the homeowner’s comfort. Keep in mind to never exceed the maximum static allowance for the furnace in order to prevent damages and ultimately warranties from being voided.
3.) Are pneumatic systems reliable?
Yes. Arzel systems operate pneumatically and have been providing comfort since 1983. We are so confident in their ability to provide reliable comfort we backed them with a lifetime warranty and our 100% comfort guarantee. Arzel is more than reliable, it’s very quiet. When installed properly, the systems perform near and less than 40 dB, which is typically the noise in a library environment.
4.) Can smart thermostats be used?
Yes. Smart thermostats that allow for conventional 24vac outputs are compatible will all Arzel zoning panels, MPS, Airboss, HPP, Evergreen, Coolmizer. We know that our contractors and homeowners have their preferred thermostats and we wanted to make sure that Arzel would be compatible with what’s familiar.
5.) Do I need a bypass?
It depends. Bypass often isn’t needed but this will depend highly on the application. Bypass is usually applied incorrectly and oversized for the application. The design and layout of the HVAC system determines whether a bypass is required. There are many ways to control the static or airflow noise in the HVAC system. We are happy to discuss proper bypass application, call us at 800-611-8312.

What is Static Pressure and Why Does it Matter in Zoning? Static pressure is basically the air pressure inside the ductwork in an HVAC system. In zoning, we use static pressure as a functional tool. When dampers close to isolate only a portion of the ductwork, that zone gets more air, more velocity and more […]
