HRV & ERV Ventilation Service
A ventilation-system review focused on filters, core condition, fans, drainage, controls and accessible airflow paths for heat- or energy-recovery ventilators.
Maintenance or active fault
Know which problem the appointment needs to solve.
Routine service addresses filters, the recovery core, drainage, hoods and available fan operation. Failed controls, motors, dampers or a full airflow-balancing requirement are separate diagnostic or commissioning scopes.
The unit is noisy, will not enter boost mode or appears unresponsive
Water, frost or a drainage concern appears around the unit
Filters, core or exterior hoods are visibly restricted
The visit starts with the actual intent.
Routine service addresses filters, the recovery core, drainage, hoods and available fan operation. Failed controls, motors, dampers or a full airflow-balancing requirement are separate diagnostic or commissioning scopes.
Make the larger decision with evidence.
A replacement decision should consider cabinet and core condition, motor and control availability, duct configuration, required airflow and whether the existing installation can be corrected without replacing the unit.

A clear service scope before the visit.
The booked appointment covers the confirmed service scope. If diagnosis reveals a separate repair or part, the customer should receive an explanation and price before authorizing additional work.
Ventilation-unit operating review
Filter and recovery-core condition review
Accessible cleaning and drainage review
15-point HRV/ERV framework
Clear findings and next-step explanation
Equipment-specific · not generic
The hrv / erv 15-point framework.
Each point explains what is reviewed and why it matters. Accessibility, equipment design, operating conditions and manufacturer requirements determine the exact steps completed.
- 01Service
Equipment identification
Confirm HRV or ERV type, controls, connected spaces and reported concern.
- 02Performance
Wall control and modes
Review normal, boost and available seasonal control response.
- 03Cleaning
Supply and exhaust filters
Inspect and clean or identify replacement needs for accessible filters.
- 04Cleaning
Recovery core
Inspect and service the core according to its type and available manufacturer guidance.
- 05Condition
Core seals and cabinet
Review accessible seals, latches and cabinet condition.
- 06Cleaning
Condensate pan
Inspect and clean accessible condensate collection areas on applicable equipment.
- 07Condition
Drain and trap
Review accessible drain routing, trap condition and evidence of blockage or leakage.
- 08Condition
Exterior hoods
Inspect accessible intake and exhaust hoods for obvious obstruction or damage.
- 09Condition
Duct connections
Review visible connections, insulation and signs of leakage or condensation.
- 10Performance
Supply fan
Observe fan operation, sound and available speed response.
- 11Performance
Exhaust fan
Observe fan operation, sound and available speed response.
- 12Condition
Dampers
Review accessible damper movement and condition where equipped.
- 13Performance
Airflow indications
Check available airflow at grilles or test ports; full balancing is a separate measured scope unless included.
- 14Safety
Electrical components
Inspect accessible power, wiring and controls for visible concerns.
- 15Service
Final operation and report
Reassemble, confirm operation and explain cleaning, observations and any balancing recommendation.
This framework communicates B.C HVAC's intended service structure. The assigned qualified professional confirms the safe, applicable and accessible work for the specific installation. It is not a substitute for the equipment manufacturer's service instructions.
A visible next step
How diagnosis becomes an informed decision.
The booked scope, any repair and any replacement estimate remain distinct so the customer can see what is being authorized.
- 01
Describe comfort and moisture
Share condensation, odour, noise, control and seasonal operating concerns.
- 02
Review both air paths
Supply, exhaust, filters, core, drainage, hoods and available control response are considered together.
- 03
Separate service from balancing
Routine cleaning, component repair and measured ventilation balancing are defined as separate scopes when appropriate.
Before you book
Questions customers ask.
Plain answers about price, scope, safety and what happens if the service identifies a repair.
Is full airflow balancing included?
Not automatically. A routine service can identify airflow concerns, while full system balancing requires dedicated measurements and should be confirmed as a separate scope if needed.
Can every recovery core be washed?
No. Core-care instructions vary, particularly between HRV and ERV media. Service should follow the equipment manufacturer's guidance.
Why is the condensate drain important?
Applicable HRVs can produce condensate. A restricted drain can lead to leakage, icing or poor operation.
Independent customer guidance
Use authoritative sources for safety and program rules. B.C HVAC does not control utility rebates or provincial qualification requirements.
