Preventive HVAC Maintenance: What Building Managers Need to Know
Preventive maintenance of heating, ventilation, and air conditioning (HVAC) systems helps reduce breakdowns, stabilize maintenance costs, and extend the lifespan of equipment. For building managers in Québec, a structured program includes inspecting filters, belts, controls, electrical connections, and cooling systems. A proactive approach also helps optimize energy consumption and avoid costly emergency service calls.
At BAULNE, building mechanics experts support businesses in implementing maintenance programs tailored to their assets and operations.
Your heating, ventilation, and air conditioning (HVAC) systems are at the core of your operations and help transform your workplace into a true living environment for your employees. In commercial and industrial buildings across Québec, HVAC system performance directly impacts comfort, productivity, and operating costs.
Not everyone is born a building mechanics technician, and it can be easy to feel overwhelmed. To help guide you, the BAULNE team has prepared this article. You’ll be better equipped to ask the right questions and make smarter decisions regarding the preventive maintenance of your equipment.
Simplified Preventive Maintenance ; a Practical Guide
At BAULNE, we’ve been supporting building managers for over 20 years with a structured approach to HVAC maintenance. As Dzmitry Puzyryn, energy performance expert at BAULNE, explains:
“Most HVAC equipment can operate for decades… but only if a rigorous preventive maintenance program is in place. Regular maintenance always costs less than a major breakdown.”

The Strategic Role of Preventive Maintenance
The goal of preventive maintenance is to establish a clear action plan to reduce the risk of unplanned downtime or failures.
In a context where buildings in Québec must deal with:
- harsh winters
- rising energy costs
- aging equipment
- increasing regulatory requirements
Preventive maintenance becomes a strategic asset management lever.
There are many advantages to having a maintenance plan in place for your HVAC system.
The Benefits of Preventive Maintenance
Better environmental performance
A system operating at peak efficiency optimizes energy consumption and reduces emissions. It’s a win for your business and the planet.
According to Natural Resources Canada, buildings account for nearly 18% of total energy consumption in the country—making HVAC optimization critical.

Reduced and predictable repair costs
A solid maintenance plan helps identify issues before they become critical. You can anticipate parts replacements and plan purchases accordingly.
This approach also integrates maintenance into your budget planning.
Long-term savings and asset protection
Preventive maintenance extends equipment lifespan and maximizes your investment.
As Jean-François Beauchamp, Director of Operations at BAULNE, states:
“In a market like Montréal, where systems are pushed hard through both extreme winters and humid summers, preventive maintenance isn’t a luxury—it’s a necessity.”
Fewer emergency calls
No one likes surprises—especially costly ones. Breakdowns always happen at the worst time.
Emergency calls are expensive and stressful for your teams. A maintenance program helps detect issues before they become critical failures.

Preventive Maintenance Inspection Checklist
A key part of any preventive maintenance plan is inspection. Here are essential points to review:
Clean and replace filters
A clogged filter reduces efficiency and increases energy consumption.
Inspect belts
Worn belts can cause fan failure and unexpected shutdowns.
Inspect equipment cabinets
Cabinets must protect equipment from weather. Mold may indicate humidity issues.
Clean condensers
Especially after the pollen season to maintain optimal performance.
Verify controls
Timers and automation systems help optimize energy usage.
Check moving parts and lubricate if needed
Ensures smooth operation and avoids premature wear.
Inspect electrical connections
Corrosion or damaged wires can pose fire risks.
Check for gas or refrigerant leaks
These reduce performance and may pose health risks.
Inspect fresh air dampers
Must operate properly to regulate airflow and avoid energy waste.
Install filters in cooling towers
Combined with UV treatment, they reduce legionella risks.
Verify water treatment
Prevents scale buildup and corrosion in cooling systems.
