Heat Recovery Ventilators (HRV)
Heat Recovery Ventilators (HRVs) are advanced systems designed to improve indoor air quality and energy efficiency. They exchange stale indoor air with fresh outdoor air while recovering heat from the outgoing air, ensuring minimal energy loss. HRVs are built for performance in varied climates and are ideal for managing moisture, providing ventilation, and maintaining temperature balance in your home.
Warrantability
Builder’s Warranty Alberta & New Home Warranty Standards:
HRVs are covered under a 1-Year Builder Warranty for both issues arising from the appliance itself and installation-related problems. Issues related to ducting defects are covered for 2 years under the mechanical systems warranty.
Manufacturer’s Warranty:
HRVs come with a 5-Year Warranty on parts. Coverage includes manufacturing defects in the motor, fan system, heat exchanger core, and electronic controls. Some models may have extended warranties for specific components; refer to your product’s warranty documents for precise coverage details.
Maintenance
To ensure optimal performance of your HRV:
Filter Cleaning/Replacement

Clean or replace filters every 1-3 months, based on usage and air quality conditions. serviceQ offers replacement filters designed for their systems to maintain efficiency.
Inspect Heat Exchanger Core
Check the heat exchanger core annually for dust or debris buildup and clean it gently using warm water and mild detergent.
Duct Cleaning

Inspect ducts for blockages or dirt accumulation and clean them every two years to maintain airflow.
Check Drain Lines

Ensure condensation drains are clear of debris to prevent water backup or leaks.
Fan and Motor Care
Monitor for unusual noise or vibrations. Lubricate parts if required (based on model-specific recommendations).
Common HVAC Issues, Warrantability, and Repair Solutions
1. Reduced Airflow or Poor Ventilation
Causes:
- Dirty or clogged filters restricting airflow (Maintenance Issue).
- Blocked or improperly connected ductwork (Installation Issue).
- Worn or defective motor or fan components (Product Defect).
- Incorrect system balancing during installation (Installation Issue).
Warrantability:
- Builder’s Warranty (1 Year): Covered if airflow issues are due to ductwork or system balancing during installation.
- Manufacturer’s Warranty (5 Years): Covered if caused by defective motor, fan, or other internal components.
- Ducting Warranty (2 Years): Covered if blocked or improperly installed ductwork causes reduced airflow.
Repair Solution:
- If within warranty period: Contact serviceQ for installation issues or support for defective components.
- If outside warranty: Clean filters and inspect ductwork for blockages. Replace worn-out or damaged motor and fan components. Rebalance the system as per manufacturer recommendations.
2. Excessive Noise or Vibrations During Operation
Causes:
- Loose mounting brackets or improperly installed ducts (Installation Issue).
- Worn motor or unbalanced fan blades (Product Defect).
- Dirt buildup on the fan causing imbalance (Maintenance Issue).
Warrantability:
- Builder’s Warranty (1 Year): Covered if noise arises from loose mounting or duct misalignment during installation.
- Manufacturer’s Warranty (5 Years): Covered if caused by defects in the motor or fan components.
Repair Solution:
- If within warranty period: Contact serviceQ for installation repairs or support for defective parts.
- If outside warranty: Secure mounting brackets and check duct connections. Clean the fan to remove dirt, lubricate components, or replace defective motor and fan components as needed.
3. Poor Heat Recovery Performance
Causes:
- Dirt or blockages in the heat exchanger core (Maintenance Issue).
- Poorly installed ductwork or incorrect balancing (Installation Issue).
- Defective or damaged heat exchanger core or control components (Product Defect).
Warrantability:
- Builder’s Warranty (1 Year): Covered if caused by installation or system balancing errors.
- Manufacturer’s Warranty (5 Years): Covered if the heat exchanger core or control system components are defective.
Repair Solution:
- If within warranty period: Contact serviceQ for performance testing and balancing. Replace defective components under warranty.
- If outside warranty: Clean the heat exchanger core to restore performance. Replace damaged exchanger cores or control components.
4. Water Leaks Around the Unit
Causes:
- Blocked or disconnected condensation drain lines (Maintenance Issue or Installation Issue).
- Improper alignment of the condensation pan (Installation Issue).
- Excess moisture buildup in ductwork due to inadequate insulation (Installation Issue).
Warrantability:
- Builder’s Warranty (1 Year): Covered if caused by installation errors, such as poorly aligned drainage components.
- Manufacturer’s Warranty (5 Years): Covered if leakage originates from defective condensation pan or drainage components.
- Ducting Warranty (2 Years): Covered if excess moisture buildup is due to insufficient insulation or duct installation errors.
Repair Solution:
- If within warranty period: Report issues to serviceQ for drainage installation problems for defective components.
- If outside warranty: Clean the condensation drain to remove blockages. Align the drain pan correctly and insulate or repair the affected ductwork.
5. Control System Malfunction
Causes:
- Faulty wiring connections during installation (Installation Issue).
- Software glitches in the control panel (Product Defect).
- Defective electronic components (Product Defect).
Warrantability:
- Builder’s Warranty (1 Year): Covered if caused by installation-related wiring faults.
- Manufacturer’s Warranty (5 Years): Covered if caused by defects in the control panel or internal electronics.
Repair Solution:
- If within warranty period: Reach out to serviceQ for wiring adjustments for hardware issues.
- If outside warranty: Inspect wiring for loose connections or damage and reset the control panel. Replace defective control components as needed.
6. Frost or Ice Build-Up in Winter
Causes:
- Improper duct insulation leading to frozen condensation (Installation Issue).
- Malfunctioning defrost mechanism (Product Defect).
- Blocked or dirty defrost damper or heat exchanger (Maintenance Issue).
Warrantability:
- Builder’s Warranty (1 Year): Covered if caused by improper duct installation or lack of insulation.
- Manufacturer’s Warranty (5 Years): Covered if caused by a defective defrost mechanism or heat exchanger.
- Ducting Warranty (2 Years): Covered if related to improperly installed or uninsulated ductwork.
Repair Solution:
- If within warranty period: Contact serviceQ for repairs.
- If outside warranty: Insulate exposed ductwork and clean defrost system components. Replace damaged or defective parts, such as the heat exchanger or damper.
