What Are ERV and HRV Systems?
Heat Recovery Ventilator (HRV)
HRV systems transfer heat between incoming and outgoing air streams, pre-warming fresh outdoor air in winter using heat from stale indoor air being exhausted. This dramatically reduces heating costs while ensuring proper ventilation in multi-unit residential buildings.
Recovers 60 to 95% of heating energy
Reduces HVAC load during winter months
Maintains consistent fresh air supply
Ideal for Vancouver’s cold, damp winters
Energy Recovery Ventilator (ERV)
ERV systems go beyond heat recovery by also transferring moisture between air streams. This is particularly beneficial for strata buildings in coastal climates like Vancouver, where humidity control is important for preventing mold and maintaining comfortable indoor conditions.
Manages both heat and humidity
Prevents excess moisture in coastal climates
Reduces condensation on windows
Better for year-round comfort in Metro Vancouver
HRV vs ERV: Which System for Your Strata Building?
For most Metro Vancouver strata buildings, we recommend ERV systems because:
Vancouver’s coastal climate requires humidity management
ERV prevents winter condensation issues common in sealed buildings
Better control of mold and mildew in high-occupancy buildings
Year-round performance in both heating and cooling seasons
Why Strata Buildings Need ERV/HRV Systems
Modern strata buildings and condominiums are built to be energy efficient with tight building envelopes. While this reduces heating and cooling costs, it also traps stale air, moisture, and indoor pollutants. ERV and HRV systems solve this problem by providing continuous mechanical ventilation.

Strata ERV/HRV Frequently Asked Questions
System Selection & Installation
What's the difference between ERV and HRV for strata buildings?
HRV (Heat Recovery Ventilator) transfers heat between incoming and outgoing air. ERV (Energy Recovery Ventilator) also transfers moisture, making it better for coastal climates like Vancouver. For most Metro Vancouver strata buildings, ERV systems are recommended to control both temperature and humidity, especially in buildings with condensation or mold issues.
How do I know if my strata building needs an ERV or HRV system?
Your building likely needs improved ventilation if you’re experiencing: condensation on windows, mold growth, musty odors, resident complaints about air quality, stuffy common areas, or high heating/cooling costs. Buildings constructed or renovated after 2008 should already have mechanical ventilation per BC Building Code.
What size ERV/HRV system does my strata building need?
System sizing depends on building occupancy, number of units, square footage, and BC Building Code requirements. VanHeat performs ventilation load calculations based on your building’s specific characteristics. Undersized systems won’t provide adequate ventilation; oversized systems waste energy and create pressure imbalances.
Can an ERV/HRV system be installed in an older building without existing ductwork?
System sizing depends on building occupancy, number of units, square footage, and BC Building Code requirements. VanHeat performs ventilation load calculations based on your building’s specific characteristics. Undersized systems won’t provide adequate ventilation; oversized systems waste energy and create pressure imbalances.

Performance & Troubleshooting
Why is there condensation on windows even with an ERV/HRV system?
Possible causes:
- System not running enough hours per day
- Inadequate system capacity for building occupancy
- Clogged filters reducing airflow
- Unbalanced airflow (exhaust exceeding supply)
- Heat exchanger clogged or frozen
- Windows themselves (single-pane or poor seals)
VanHeat can diagnose the cause and recommend solutions, which may include increasing runtime, balancing airflow, or supplementing with additional ventilation.
Why does our ERV/HRV system make noise?
Common noise sources:
- Worn motor bearings (grinding sound)
- Unbalanced fan blades (rumbling)
- Loose mounting (vibration)
- Damaged heat exchanger (rattling)
- Ductwork issues (whistling)
- Inadequate vibration isolation (structure-borne noise)
Most noise issues can be resolved through repair or adjustment. VanHeat can assess your system and recommend solutions to meet strata noise bylaws.
Why are some units getting more/less ventilation than others?
Airflow imbalances occur due to:
- Improper duct sizing during installation
- Blocked or restricted ductwork
- Dampers not properly adjusted
- Different pressure conditions between units
- Resident modifications (blocked vents, closed doors)
VanHeat can rebalance your system using airflow measurements and damper adjustments to ensure each unit receives proper ventilation per BC Building Code.
Can ERV/HRV systems help with mold problems in our strata?
Yes! Mold growth requires three conditions: moisture, organic material (drywall, wood), and warm temperatures. ERV/HRV systems eliminate the moisture component by:
- Controlling humidity levels throughout the building
- Providing continuous fresh air circulation
- Removing moisture-laden air from bathrooms and kitchens
- Preventing condensation on surfaces
Many strata buildings have successfully resolved mold issues by upgrading their ventilation systems. However, existing mold must be professionally remediated before improved ventilation can prevent recurrence.
Why does the system freeze up in winter?
Winter freezing can be caused by:
- Inadequate or malfunctioning defrost cycle
- Blocked condensate drain
- Unbalanced airflow (too much exhaust vs supply)
- Outdoor temperature below system rating
- Damaged or clogged heat exchanger
VanHeat can diagnose freezing issues and implement solutions like defrost cycle adjustment, preheating, or condensate management improvements.
How much energy does an ERV/HRV system save?
Energy savings vary by building but typically:
- 60-95% of heating/cooling energy recovered (compared to opening windows)
- 20-40% reduction in HVAC operating costs
- $500-$5,000+ annual savings for typical strata buildings
- ROI within 7-10 years
Actual savings depend on building size, occupancy, climate zone, and existing HVAC efficiency. VanHeat can provide estimates based on your specific building.
