Restaurants, offices: what your clients are really breathing (the story of a ventilation cleaning that changed everything)

A CVAC cleaning operation that transformed the customer experience in a Greater Montréal establishment

In the world of restaurants and office spaces, indoor air quality is often overlooked – until the effects become too obvious (or perceptible) to ignore. At AirGreen, we recently carried out a ventilation cleaning intervention in a restaurant combined with an office space located in Laval, and the results far exceeded the client’s expectations. Here is a concrete story of this transformation, revealing what your clients – and your employees – are really breathing.

Why this ventilation cleaning had become essential

The establishment in question – a popular restaurant located in a commercial area, with open-plan offices upstairs – showed clear signs of poorly maintained ventilation:

• Persistent cooking odors despite active hoods

• Clients complaining about stuffy, humid, and warm air

• Employees experiencing frequent headaches and fatigue

• Presence of greasy dust and visible particles on ventilation grilles

The owner, concerned about the customer experience and staff well-being, contacted us for a complete analysis of their CVAC system.

Diagnosis: clogged ventilation, ineffective air exchange

After a detailed inspection with a camera, we discovered:

• Air ducts completely clogged with grease residues, dust, and mold

• A kitchen air extraction system operating at drastically reduced capacity

• A lack of regular maintenance for more than five years

These combined factors were severely affecting indoor air quality, impacting not only customers but also employee performance.

Cleaning process: a thorough and tailored approach

The intervention was carried out over two full days, outside business hours. Here are the main stages:

Job site preparation

• Protection of all surfaces (furniture, counters, IT equipment)

• Safe access to wall and ceiling ventilation ducts

Mechanical and chemical cleaning

• Use of high-pressure rotary equipment to dislodge grease in the kitchen ducts

• Cleaning of exhaust vents in the offices with a biodegradable anti-mold solution

• Industrial HEPA vacuuming of fine particles and residues

Disinfection and final inspection

• Application of an approved antibacterial and antifungal agent

• Verification of airflow and recalibration of air exchangers

• Delivery of a detailed report with before/after photos

Result: a noticeable improvement within the first few hours

As soon as the restaurant reopened, the owner noticed an immediate improvement:

• The air felt fresher, lighter, and free of lingering odors

• Customers stayed longer, and several even commented on the “new atmosphere”

• Staff reported increased energy and fewer headaches

• The CVAC system is now quieter and more efficient

This intervention also allowed the client to comply with local air quality standards for commercial environments.

Why regular duct maintenance is essential

Many restaurant or office owners are unaware that ventilation systems quickly accumulate particles, grease, spores, and invisible pollutants. This has direct consequences on:

• The respiratory health of occupants

• The lifespan of the CVAC equipment

• Energy consumption (up to 20% overconsumption due to buildup)

At AirGreen, we recommend a complete CVAC cleaning every 2 to 3 years, or annually in environments with high particle production (restaurants, commercial kitchens, workshops).
