These advanced HRV and ERV ventilation systems continuously bring fresh, filtered air into your home while recovering heat or energy from the outgoing air- keeping your home comfortable and your energy use efficient.

The result?

Cleaner air, balanced humidity, quieter operation, and a home that simply feels better to live in.

Custom System Design & Regional Support

Every Zehnder ComfoSystem begins with a custom design tailored to your home’s layout, size, and performance goals. Our team carefully reviews your plans to engineer a balanced ventilation system that delivers optimal airflow, efficiency, and comfort.

We proudly provide system design, equipment sales, and servicing throughout Washington, Oregon, and California. If your project is located in one of these states, our team can guide you through the entire process- from design and quoting to system support.

Once you submit your project details, we’ll review the information and prepare a thoughtfully engineered custom system design, typically within 7–14 business days.

And while full system support is regional, replacement filters are available nationwide. We ship Zehnder filters anywhere in the United States—because even the best ventilation system needs a fresh filter now and then. Your lungs (and your Zehnder) will appreciate it.
