Heat Recovery Ventilators (HRV)

(HRV) Heat Recovery Ventilators

The Heat Recovery Ventilators (HRV) category features balanced ventilation systems that exchange stale indoor air with fresh outdoor air while recovering heat from the exhaust airstream. HRVs are especially valuable in cool and cold climates where uncontrolled ventilation can drive up heating costs. By transferring heat from outgoing air to incoming air, HRVs help maintain comfort, protect building envelopes, and support healthy indoor air quality.

HRVs are a strong fit for tight, energy-efficient homes, multi-family projects, and light-commercial buildings where natural infiltration is low and code-driven ventilation requirements are higher. These systems reduce the buildup of CO₂, VOCs, odors, and excess indoor humidity while minimizing the impact on heating systems. Many units include ECM motors, multiple fan speeds, frost protection strategies, sound-attenuated housings, and serviceable heat-exchanger cores to simplify installation and maintenance.

• Whole-house HRV systems for balanced fresh air in cold and mixed climates.
• Compact and multi-position HRVs for tight mechanical rooms, attics, and closets.
• ECM fan HRVs designed for continuous or demand-based ventilation.
• HRV units with integrated defrost control for reliable winter operation.
• Filter and core access panels designed for quick service and cleaning.

When selecting an HRV system, consider the building’s square footage, number of bedrooms, required air changes per hour (ACH), duct routing options, and climate zone. Use the Compare tools on this page to evaluate airflow (CFM), heat recovery efficiency, external static pressure, defrost strategy, noise ratings, and cabinet configuration (horizontal, vertical, or multi-position) so you can choose the right HRV for your project.

Pro tip: Before installing an HRV, document the location of existing returns and supplies, preferred fresh air and exhaust terminations, available mounting area, and access for filter and core service. Share basic plans, photos, and climate details and we can help you select a properly sized HRV, control package, and installation accessories that meet ventilation codes and keep heating loads under control.
