A poorly maintained ERV: Why your health is at stake and how to act quickly in Montreal and surrounding areas
At AirGreen, recognized HVAC specialists serving Montreal, Laval, Longueuil, as well as the North Shore and South Shore, we regularly encounter situations where a neglected energy recovery ventilator (ERV) seriously compromises indoor air quality, posing risks to the health of occupants. Here are the specific signs that should alert you immediately and the solutions our team recommends for addressing them quickly and effectively.
Recognizing symptoms of an ERV potentially hazardous to your health
Numerous interventions by AirGreen have uncovered malfunctioning ERVs directly exposing occupants to health issues. If you live in Montreal or surrounding cities, carefully watch for these indicators:
-
Frequent mold growth on walls, ceilings, or windows.
-
Recurring allergic symptoms among household members (respiratory irritation, chronic cough, persistent headaches).
-
Visible dust accumulation despite regular cleaning.
-
Persistent, unusual odors inside the home.
These signs typically indicate that your ERV is no longer adequately filtering and refreshing your indoor air.
Why improper ERV maintenance poses a real health hazard
During our visits to homes in Montreal, Laval, or Longueuil, we have identified several primary reasons behind the dangers linked to poorly maintained ERVs:
-
Clogged filters: Dirty filters promote the growth of bacteria and mold, contaminating indoor air.
-
Inefficient heat exchange: When heat exchange is compromised, your ERV fails to adequately remove excess humidity, creating conditions favorable for contaminants.
-
Improper settings: Inadequate adjustments severely limit your ERV's ability to refresh air, thereby increasing indoor pollutant concentrations.
AirGreen case study: Diagnosis and repair of a Venmar AVS E15 ECM ERV in Laval
Recently, our team was called to a home in Laval equipped with a Venmar AVS E15 ECM ERV. The occupants had been experiencing recurring respiratory issues and abnormally high humidity levels in their bedrooms for several months.
Our thorough inspection revealed an alarming condition: completely clogged filters, dust-obstructed fans, and improper settings for incoming and outgoing airflow. Our team immediately performed the following actions:
-
Immediate replacement of filters with high-efficiency certified models.
-
Comprehensive and meticulous cleaning of internal ducts and fans.
-
Precise airflow adjustments tailored to the home's exact specifications.
The result: within just a few days, our clients experienced a significant improvement in their quality of life, notably a noticeable decrease in respiratory symptoms and complete elimination of excess humidity.
Concrete actions to immediately safeguard your ERV in Montreal and surrounding areas
If you reside in Montreal, Laval, Longueuil, or areas on the North Shore or South Shore, here are the urgent measures our team recommends to ensure a healthy indoor environment:
-
Systematically replace your ERV filters every 3 to 6 months based on usage.
-
Schedule comprehensive annual maintenance performed by experienced professionals like AirGreen to ensure proper operation and optimal system settings.
-
Temporarily increase ERV fan speed during critical periods (heavy cooking, prolonged showers) to prevent excessive humidity buildup.
Common mistakes you absolutely must avoid with your ERV
Throughout our interventions, here are frequent mistakes we strongly advise against:
-
Running your ERV at the same speed year-round without appropriate seasonal adjustments.
-
Continuously postponing recommended annual maintenance thinking you're saving short-term costs.
-
Ignoring or underestimating obvious symptoms of malfunction (unusual noises, excessive humidity, etc.).
