Commercial HVAC Cleaning: Keep your building breathing easy with expert care from Breathe Clean Alberta

The Importance Commercial HVAC Cleaning
Keep your building breathing easy with expert care from Breathe Clean Alberta

At Breathe Clean Alberta, we know that clean air doesn’t just happen—it’s the result of proactive maintenance, proper equipment, and professional expertise. While most people associate HVAC cleaning with homes and smaller offices, large-scale commercial buildings—from multi-storey offices and shopping centres to industrial plants—have their own complex systems that require specialized attention. Rooftop units, air handling systems, make-up air units, ductwork, and exhaust vents all play a critical role in building performance, air quality, and occupant health.

In a commercial setting, neglecting HVAC system cleaning can lead to decreased system efficiency, costly repairs, increased energy consumption, and poor indoor air quality that affects both staff and customers. That’s why Breathe Clean Alberta offers commercial HVAC cleaning services tailored to the unique demands of large-scale systems—because clean, breathable air matters everywhere.

Rooftop Units and Air Handling Systems Need Regular Attention

Rooftop units (RTUs) and air handling units (AHUs) are the workhorses of many commercial HVAC systems. These large systems manage heating, cooling, and ventilation for entire buildings, often running around the clock. Over time, dirt, debris, pollen, and even bird droppings can build up inside and around these units, reducing airflow and forcing motors and fans to work harder than they should.

We recently serviced a mid-sized commercial plaza in Calgary where several rooftop units hadn’t been cleaned in over five years. The intake screens were caked with debris, and the coils were significantly clogged, reducing cooling efficiency during the summer months. After a thorough cleaning, the building manager reported a noticeable drop in energy use and a significant improvement in cooling performance.

Routine inspection and cleaning of these systems not only extends the life of the equipment but also improves energy efficiency and airflow throughout the building. At Breathe Clean Alberta, we use specialized equipment designed to safely clean commercial RTUs and AHUs without causing damage or disruption to your business operations.

Make-Up Air Units Are Essential—But Often Overlooked

Make-up air (MUA) units supply fresh air into a building to replace air that is exhausted by ventilation systems. This is especially important in commercial kitchens, warehouses, and industrial spaces where fumes, odours, or contaminants need to be continuously removed. However, because MUA units are often installed on rooftops or in mechanical rooms, they can be easily forgotten when it comes to maintenance.

A well-maintained MUA system is crucial not only for comfort but for safety. We recommend having these systems cleaned and inspected at least once per year, or more frequently in environments with higher particulate loads.

Clean Ductwork and Vents Improve Air Quality and System Performance

The ductwork in a large commercial building is like the circulatory system of the HVAC infrastructure. Over time, dust, allergens, construction debris, and even mould can accumulate in these passages—especially in buildings with multiple tenants, varying uses, or past renovation work.

We recently cleaned the ventilation system of a large office complex in downtown Calgary. The building had undergone several tenant changes over the years, and the ducts had never been professionally cleaned. Our team removed accumulated debris from the system, improving airflow and reducing airborne allergens. Employees reported fewer symptoms of dry eyes, coughing, and sinus issues after the cleaning.

In addition to improving indoor air quality, clean vents and ducting help HVAC systems operate more efficiently and reduce wear on fans and motors. For property managers and building owners, this means fewer complaints, better tenant satisfaction, and lower maintenance costs in the long term.

Trust Breathe Clean Alberta for Your Commercial HVAC Needs

Large-scale commercial HVAC systems require more than just routine filter changes—they demand professional attention and deep cleaning from experts who understand their complexity and importance. At Breathe Clean Alberta, we specialize in commercial HVAC cleaning tailored to the needs of property managers, facilities teams, and business owners across Calgary and the surrounding area.

Our team uses high-powered portable units and van-mounted air compressors to deliver exceptional results safely and efficiently. We avoid using rotary brushes or agitators, which can damage ductwork, and instead rely on equipment and techniques designed to preserve your system while providing a thorough clean.

Whether you manage a multi-storey building, a shopping centre, or an industrial facility, we’re here to help ensure your HVAC system is clean, efficient, and delivering fresh, healthy air.
