Ventilation & Air Handling Units (AHUs) -Saskatoon 

Clean, Balanced Air for Every Commercial Space 

Proper ventilation is essential for maintaining a safe, healthy, and productive indoor environment. From large warehouses to schools, offices, and healthcare facilities, buildings rely on Air Handling Units (AHUs) and custom ventilation systems to ensure optimal indoor air quality and airflow. 

At MNS Mechanical Limited, we design, install, and service commercial ventilation systems that promote clean air, regulate humidity, and support energy efficiency across Saskatoon.

Why Ventilation & AHUs Matter in Commercial Buildings

Without proper ventilation, your indoor environment can become stale, humid, and potentially hazardous. 

Poor air circulation contributes to health issues, equipment failure, and code violations. 

AHUs are the backbone of your ventilation system—drawing in outdoor air, conditioning it, filtering it, and distributing it throughout your building.

Frequently Asked Questions About AHUs and Ventilation Systems 

  • What is an AHU?

    An Air Handling Unit is a centralized system that distributes and conditions air throughout your building. It includes components such as filters, fans, coils, and dampers. 

  • Do I need a Make-Up Air Unit?

    Yes, especially in buildings where air is exhausted regularly (e.g., kitchens, shops, labs). MUA units bring in tempered outdoor air to replace exhausted air. 

  • How often should I maintain my AHU?

    We recommend quarterly filter changes and annual inspections of fans, coils, and dampers for optimal performance. 

  • Can I upgrade my old ventilation system without replacing everything?

    Absolutely. We offer retrofit services that improve performance and energy efficiency without full system replacement.
