Common mistake: Why your HRV is probably underused (and how to fix it quickly)

Your HRV probably isn't running at full capacity: Here's how AirGreen optimizes your comfort in Montreal and surrounding areas

Among the HVAC installations we regularly perform at AirGreen in Montreal, Laval, Longueuil, the North Shore, and the South Shore, one of the most common mistakes we notice is the underuse of heat recovery ventilators (HRVs). Many homeowners aren’t aware of their HRV’s true capabilities, resulting not only in wasted money but also significantly reduced indoor comfort. Through our field experience, discover how to quickly address this widespread issue.

Telltale signs of an underused HRV in your home

At AirGreen, we frequently intervene in homes where owners are convinced their ventilation system is functioning correctly. Yet, our diagnostics often reveal a different reality. Here are the most common signs indicating underuse:

  • Stagnant indoor air despite regular ventilation.

  • Constant presence of excessive humidity, especially in winter.

  • Persistent odors in certain rooms despite continuous ventilation.

  • Unusually high electricity or heating bills without an obvious cause.

If your home in Laval, Longueuil, or elsewhere in the Montreal area displays these symptoms, chances are your HRV isn’t being used to its full capacity.

Why is your HRV likely underused?

In our daily practice in Montreal and surrounding cities, we typically notice the same reasons causing underuse:

  • Initial insufficient setup: Many installations are configured at ventilation levels too low for occupants' real needs.

  • Lack of understanding of controls: Often, occupants were never shown how to adjust their HRV according to seasons or their specific requirements.

  • Neglected maintenance: A poorly maintained HRV drastically loses efficiency, significantly limiting its performance.

AirGreen case study: optimizing a Lifebreath MAX Series HRV in Longueuil

Let’s consider a concrete example from a Longueuil client equipped with a Lifebreath MAX Series HRV previously installed by another company. Upon our arrival, the client complained of persistent odors, excessive humidity, and ongoing discomfort.

After analysis, we found their HRV was continuously running at a low intensity, insufficient for their actual needs. Additionally, the filters were partially blocked, further reducing fresh air circulation. Our technicians performed the following interventions:

  • Precisely adjusted airflow rates calibrated according to the home’s area and actual ventilation needs.

  • Deep cleaning and replacement of filters to ensure optimal airflow.

  • Comprehensive homeowner training on proper use and regular maintenance of their HRV.

Following this quick and effective intervention, our client immediately noticed a significant improvement in indoor comfort and a notable reduction in energy costs.

Quick solutions to immediately optimize your HRV

If you own a home in the Montreal region, Laval, Longueuil, North Shore, or South Shore, here are immediate steps to optimize your HRV performance:

  • Check and adjust airflow rates: Increase fan speeds during periods of intensive activity (cooking, showering, etc.) and reduce them during quiet periods.

  • Regularly change your filters: Periodic replacement ensures better air quality and reduces unnecessary strain on your HRV.

  • Have your installation inspected annually: An AirGreen specialized technician will thoroughly check the entire system and perform necessary adjustments to maximize performance.

Practical advice from AirGreen: common mistakes to absolutely avoid with your HRV

During our interventions, here are the most frequent mistakes we strongly recommend you avoid:

  • Never adjusting your HRV: Keeping a single setting year-round leads to waste and discomfort.

  • Ignoring unusual noises or signs of internal component wear.

  • Constantly postponing annual maintenance thinking you’re saving money: in the long run, this will cost much more in repairs or replacement.
