Why Modern Condos in Montreal Often Have Poor Ventilation (and How to Quickly Fix It)

Main Causes of Ventilation Problems Observed by AirGreen in New Condos in Montreal, Laval, and Longueuil

At AirGreen, during our HVAC installation and maintenance services across Montreal, Laval, Longueuil, the North Shore, and the South Shore, we frequently observe that new condos often have significant deficiencies in ventilation. While these modern buildings are designed to offer comfort and energy efficiency, they too often suffer from inadequate air circulation, causing notable impacts on occupants' comfort and health.

Through our field expertise, we have clearly identified the main causes of these issues, along with concrete and rapid solutions to address them permanently.

Common Technical Causes Responsible for Poor Ventilation in Modern Condos

During our comprehensive diagnostics performed in recent condos around Montreal, we typically find the following issues:

  • Improperly sized ventilation systems: Air exchangers (HRV or ERV) installed are often poorly calibrated relative to the actual size of the unit and number of occupants.

  • Poorly designed or executed installations: A lack of professionalism in the initial design leads to poor air circulation, often characterized by excessively long or poorly insulated ducts.

  • Insufficient or nonexistent filtration: Many recent condos have systems without HEPA filters, allowing fine particles and allergens to accumulate in indoor air.

  • Lack of regular maintenance of HVAC installations: Absence of regular cleaning of ducts and filters significantly worsens ventilation problems.

AirGreen Case Study: Successful Restoration of Optimal Ventilation in a Griffintown Condo

A client from Griffintown, Montreal, recently contacted us urgently, frustrated by the constant feeling of stuffiness and recurring humidity issues in his new condo. After a detailed technical inspection, our specialists uncovered several critical issues with the initial installation of the ventilation system.

Our AirGreen technicians immediately undertook the following corrective measures:

  • Installation of a high-performance ERV air exchanger, the Venmar AVS X24ERV ECM model, specifically suited to the condo's requirements.

  • Comprehensive revision and precise adjustment of existing ducts to optimize airflow.

  • Installation of HEPA filters to effectively eliminate allergens and enhance overall indoor air quality.

In just a few days, the condo's air quality and overall comfort significantly improved, once again demonstrating the importance of professional, targeted intervention.

Mandatory Regular Maintenance to Preserve System Efficiency

The key to maintaining optimal ventilation lies in rigorous, regular HVAC maintenance:
