Heat Recovery Ventilators (HRV)

A Heat Recovery Ventilator (HRV) provides balanced ventilation by bringing in fresh outdoor air and exhausting stale indoor air while transferring heat between the two air streams. Unlike an ERV, an HRV typically does not transfer moisture—making it a strong choice for colder or drier climates where humidity control is less of a concern.

HRVs help reduce indoor pollutants, odors, and stuffiness in tighter buildings while minimizing energy loss from ventilation. When properly sized and installed, HRVs support consistent comfort, healthier indoor air, and better overall system performance.

• Compare airflow (CFM) for square footage, occupancy, and code requirements
• Best fit for cold/dry regions where moisture transfer isn’t desired
• Choose ducting method: dedicated ducts vs HVAC integration (when allowed)
• Confirm filtration and maintenance access for long-term reliability

If your home feels stale in winter, ventilation is often the missing piece. An HRV can provide steady fresh air without dumping heated indoor air directly outside.

Pro tip: Use proper balancing during commissioning. An HRV that isn’t balanced can create pressure issues, drafts, and reduced real-world airflow.
