Zehnder HRVs and ERVs

Zehnder HRVs and ERVs

In the Zehnder Academy, we share information and resources to better understand the role of heat and energy recovery ventilators in high efficiency buildings.

Let us provide complimentary design and quote service.

This process assures that the installation meets the design criteria used to maximize comfort, efficiency, proper ventilation, and operation.

How the Zehnder Home Ventilation System Works



Poor indoor air quality can lead to a rise in asthma and allergic symptoms due to the increased concentration of allergens such as dust mites, VOCs, pollen and mold.


Good air quality through continuous extraction of moist, stale air from bathrooms and kitchens and a continuous supply of clean, tempered air to habitable rooms. Low velocity air supply ensures that fresh, clean air does not create drafts around the home.

Energy Efficiency

Zehnder Comfosystems products use recovered and renewable energy sources. Whole house heat recovery ventilation technology can recover up to 90% of the heat and contribute to an energy savings of up to 50%.

What Our Customers Say…

At Ryall Sheridan Architects, Zehnder is our go-to energy recovery ventilation system for all of our projects.  We’ve used the Comfoair units in all sizes on residential and institutional projects and had nothing but good results.  On our most efficient net-zero and Passive House designs, the Zehnder system with the Zehnder commissioning is the surest way we’ve found to have efficient, quiet and easy to maintain systems– with great indoor air quality.

The products – and just as importantly, technical support – I get from Zehnder are unparalleled. That’s why I continue to spec their products for nearly every project I work on. The efficiency, flexibility, and ease of installation mean that good indoor air quality is virtually guaranteed.”

I chose a Zehnder ERV for my own zero net energy retrofit in 2013. In addition to the high quality of the products, I appreciate the responsive support provided by the team at Zehnder America.

Ventilation and indoor air quality are too important to leave to inferior systems. Zehnder ERVs have become our go-to solution for excellent indoor air quality. The ERVs’ thermal and electrical efficiency, exceptionally quiet operation, and inherently air-tight distribution system satisfy everything we’re looking for in a ventilation system.
