Eight Reasons Why Arzel Is Your Best HVAC Zoning Solution

For 40 years, we’ve been proving that Arzel is your best HVAC zoning solution. We are proud to offer these 8 reasons why.


Arzel®’s line of EzySlide dampers can typically be installed in less than 5 minutes, in 3 simple steps, making them perfect for retrofit applications. These dampers are available in branch sizes 4″ through 16″ and trunk sizes 8X8 through 12X28. They come in side- and bottom-mounted configurations. The round EzySlide dampers have a sticker template that adheres to the sheet metal ductwork or sleeve. After a triangular slot is cut into the sheet metal duct, the damper is inserted and secured with just four sheet metal screws. The rectangular trunk dampers are installed by cutting a 5″ diagonal slot into the trunk line and inserting sheet metal screws into the damper mounting plate. That’s it! No running low voltage wires, just cut, fit and secure!

Retrofit zoning done right


Arzel® stands behind our line of air-driven dampers by offering a limited lifetime warranty. You won’t find that on ANY mechanical damper system on the market today. Why? Because the motors, gears, and wiring connections on other motorized dampers can cause failure issues in a much shorter period. The air-driven Arzel® damper has NO moving parts except the damper itself. No moving parts = Nothing to fail! And we’re so sure of our superior, made in the USA, construction that we’ll stand behind it now and down the road.


Arzel® offers a damper size and style for almost any HVAC application you might find yourself in. Since Arzel® dampers aren’t dependent on a large, heavy motor to operate, we have much more flexibility in designing our dampers. That means there are more sizes and styles available for you. Arzel® also offers dampers for when you don’t have access to ductwork – products such as our Ezy-Fit, Regi damper, and Inserta damper. These adaptable dampers make retrofit zoning a simple job.


Arzel® dampers are the quietest dampers on the market. Noise is a common complaint of mechanical damper systems, because of the sound generated by dampers opening and closing.  Since no motors are attached to Arzel® dampers, there’s no noise problem. Air-driven dampers are quieter.


Arzel® makes retrofit zoning affordable with our line of Ezy-Slide dampers. Our EzySlide dampers are typically up to 50% less than their mechanical counterparts. Installation materials are also less costly. For one thing, no transformers are necessary for our dampers. When you are installing branch dampers, those transformers can add up. With Arzel®, you just run tubing instead of low voltage wire – one roll of 200ft PVC tubing is roughly $22 to the contractor – wire is about 2 to 3 times that amount depending on the current rates of copper. Significant savings – not just on the dampers but also on the installation materials and labor time.


Arzel® offers a quick turnaround time for custom dampers and control panels. Do you need a damper size that isn’t considered “stock”? No problem! Arzel® manufactures custom dampers within 24 hours, allowing you to complete your job quickly. Same with custom panel configurations. With US manufacturing and our responsive customer support, Arzel® can build and ship any custom panel configurations required for your application.


Arzel® offers unsurpassed technical support in all aspects of our product line. LIVE technical support is available from 8 AM-9 PM EST Monday through Sunday – we pride ourselves on having support readily available to get you on quickly and off the phone. And if you sign up for our contractor portal, you can gain 24/7/365 access to training, support materials, and more.

The 100% Comfort Guarantee states that if the homeowner is unsatisfied with their Arzel® system after it’s been installed and running for one year, Arzel® will buy the materials back from the installing contractor. What better way to make a sale than not just warranty the parts of a product but guarantee that the product will satisfy the customer’s comfort issues?
