Poorly maintained HVAC systems can cost far more than a mechanical breakdown: they can sabotage your business reputation—especially in the restaurant industry. At AirGreen, we’ve seen firsthand how lack of HVAC maintenance can trigger a series of disastrous consequences for restaurants across Montréal, Laval, Longueuil, the North Shore and the South Shore. In this article, we’ll explain how a simple oversight in maintenance can turn into a full-blown image crisis—and how to avoid it with a proactive and rigorous approach to HVAC system care.
A neglected HVAC system: the warning signs your customers notice… before you do
One of the most critical elements in the restaurant business is customer experience. The atmosphere, temperature, air quality, and absence of unpleasant odors all play a major role. And yet, the moment your HVAC system starts to show signs of decline—a noisy air conditioner, persistent smells, uneven temperature—your clients are the first to notice. Often, their first reaction is to leave a review online.
Real-world example: In summer 2023, a restaurant in Old Montreal saw its Google rating drop from 4.6 to 3.9 in just two weeks, after five negative reviews mentioned stifling heat and lingering kitchen odors. After inspection, we discovered that the ventilation system hadn’t been cleaned in over 18 months.
One bad review can hurt your revenue
In Montréal’s ultra-competitive restaurant scene and surrounding areas, just one bad Google or Yelp review can lead to:
-
Immediate loss of potential customers
-
Lower traffic during off-peak hours
-
Decreased revenue
-
Increased marketing costs to counterbalance a damaged reputation
The reason? A poor impression often tied to an uncomfortable environment—air that’s too hot, too cold, stagnant, or smelly—directly linked to insufficient HVAC maintenance.
The most common maintenance mistakes in restaurants
Clogged air filters
Dirty filters reduce air quality, spread allergens, and put additional strain on the system. This results in inconsistent temperatures in the dining area and higher energy bills.
Neglected kitchen ventilation systems
Uncleaned ducts can lead to flammable grease buildup and poor odor control, hurting the ambiance and potentially causing a temporary shutdown by health inspectors.
Poorly calibrated equipment
A misadjusted wall-mounted air conditioner, or a faulty thermostat, can cause hot or cold spots throughout your space, making the establishment feel neglected. Worse, it signals that the owner doesn’t care about the customer’s comfort.
How AirGreen protects our restaurant clients' reputations
At AirGreen, we regularly serve restaurants across Laval, Montréal, Longueuil, the North Shore, and the South Shore, providing rigorous preventative maintenance for their HVAC systems.
Case study: Family-owned restaurant in Longueuil
A restaurateur contacted us after receiving a negative comment mentioning “overwhelming heat in July.” Our team arrived on-site the next day for a complete diagnosis. What we found:
-
A clogged filter
-
An outdoor unit covered in debris
-
An uncalibrated thermostat
We immediately cleaned the components, replaced the filters, and adjusted the settings. The owner received a personalized maintenance plan, and within two weeks, new customer reviews were once again highlighting the restaurant’s comfortable atmosphere.

Train your staff to spot early warning signs
We provide our clients with a simple checklist their staff can use to quickly detect anomalies: unusual noises, bad odors, fluctuating temperature, abnormal condensation.
