HRV & ERV
Ventilation Systems
Modern, tightly sealed homes trap stale air, moisture, and elevate CO2 levels. We design and install long-lasting Heat Recovery Ventilator (HRV) and Energy Recovery Ventilator (ERV) systems that introduce a continuous stream of filtered outdoor air while capturing up to 80% of your indoor heating energy before it leaves the building envelope.

Heat Recovery (HRV)
Ideal for our core Vancouver Island winter climate. Extracts heat from exhaust air and transfers it to incoming fresh air, protecting indoor air quality without wasting heat efficiency.

Energy Recovery (ERV)
Advanced climate balancing that transfers both heat and moisture, balancing humidity levels between indoor and outdoor air throughout the year.

BC Step Code Compliance
Tightly sealed modern homes require dedicated mechanical ventilation to pass inspection. We install code-compliant systems that satisfy BC Step Code metrics and protect the building envelope.

Heat Recovery Ventilators for Custom Builds & Upgrades
High-efficiency heating systems keep your home warm, but airtight building envelopes lock in everyday contaminants, indoor humidity, and stale air. An HRV resolves this by continuously swapping old indoor air with fresh, filtered outdoor air. Inside the core, the outgoing warm air preheats the incoming cold air without the two airstreams ever mixing. This process gives you completely fresh air without forcing your primary heat pump or furnace to work double-time to reheat the space.

Energy Recovery Ventilators & Moisture Management
While an HRV only transfers heat, an ERV manages both thermal energy and humidity. During drier winter months, an ERV recovers moisture from outgoing bathroom and kitchen exhaust streams, transferring it to incoming fresh air to prevent your home from feeling uncomfortably dry. In the summer, it reverses this process to keep outdoor humidity outside. We analyze your home size, occupant density, and heating layout to recommend the exact system type required.

Meeting BC Step Code Metrics with Engineered Ventilation
As the BC Energy Step Code demands new construction on Vancouver Island to be increasingly airtight, passive ventilation is no longer an option. Tightly sealed homes trap interior moisture, leading to structural rot if not mechanically vented. We work alongside builders and energy advisors to ensure your HRV or ERV layout meets mandated ventilation requirements. Every system we install is properly balanced using custom ductwork configuration to maintain neutral house pressure, keeping air delivery silent while meeting building regulations.

HRV & Exhaust Ventilation System | Thetis Island, Cowichan Valley, BC
This custom new construction build required a comprehensive, continuous fresh air plan to satisfy local building code requirements and ensure long-term structure efficiency and protection. We engineered and ran a complete, balanced HRV distribution loop hidden cleanly inside the framing.
- Thermal Condensation Barrier: Wrapped ducting in insulation to prevent condensation from forming in or around the duct.
- Custom Fabrication: Utilized custom-fabricated smooth wye branches to ensure proper efficiency.
- Pressure Equalization: Installed a dedicated cushion head to allow airflow to stabilize, promote pressure regain, and maintain proper air velocities.
