Optimize Every Winter with a Rigorous and Efficient Maintenance Routine
In the world of commercial heating, efficiency, reliability, and durability are not luxuries — they’re absolute necessities. At AirGreen, we know that ensuring optimal thermal comfort in commercial buildings across Montreal, Laval, Longueuil, the North Shore and the South Shore requires following a precise and rigorous annual maintenance schedule. Whether you're a building manager, business owner, or technical supervisor, this 10-step annual checklist will help you keep your heating system running at peak performance, extend its lifespan, and keep your energy costs under control.
Why an Annual Checklist Is Essential
A commercial heating system—whether it’s a central heat pump, a forced-air furnace, or a warm air system with a heat exchanger—must meet high standards for performance and safety. Natural wear, buildup of residue, clogged filters, or poorly adjusted components can compromise comfort and drive up your energy bills.
Our hands-on experience with multiple commercial installations across Montreal and the surrounding areas shows that well-planned maintenance makes all the difference. Here is our technician-approved checklist, tested in the field, that should ideally be completed in the fall, before the deep cold arrives.
Step 1: Complete HVAC System Inspection
First, our certified technicians perform a full visual and mechanical inspection: ductwork, exchangers, fans, thermostats, electrical wiring, and control panel connections. This allows us to detect signs of wear, leaks, or electrical failures. A professional diagnosis is crucial to prevent breakdowns in the middle of the season.
Step 2: Deep Cleaning of Filters
Clogged air filters can cause up to a 15% drop in energy efficiency. At AirGreen, we clean or replace filters based on the manufacturer’s specifications (HEPA, MERV 13, or others) to ensure optimal indoor air quality and steady performance.
Step 3: Safety Component Inspection
Safety is paramount, especially in gas-powered systems. Our teams thoroughly test carbon monoxide detectors, overheat protection devices, and automatic shut-off systems to provide maximum safety for both personnel and the building.
Step 4: Pressure and Airflow Checks
We perform a static pressure test and adjust motorized dampers to ensure balanced airflow throughout the building. This is especially important in large commercial spaces, where cold or hot zones can emerge if the airflow is unbalanced.
Step 5: Recalibrating Programmable Thermostats
Poor or outdated programming of your central thermostat can lead to major energy waste. We recalibrate your thermostat based on your business hours, occupancy zones, and seasonal weather to optimize energy use.
Step 6: Combustion Analysis (for Gas or Oil Systems)
Using digital analyzers, we measure CO, CO₂, and O₂ levels in exhaust gases to ensure clean, complete, and safe combustion. A poor air/fuel mixture can be both dangerous and expensive over time.
Step 7: Lubricating and Mechanically Inspecting Motors
Blower motors and circulation fans are under heavy stress. Proper lubrication and precise balancing help reduce premature wear and operating noise while improving system longevity.
Step 8: Cleaning Coils and Heat Exchangers
Dirty coils are a common cause of energy overuse. We carry out a safe and gentle chemical cleaning that restores your system’s thermal performance, especially in systems that combine heating and cooling functions.
Step 9: Ductwork and Insulation Check
A poorly insulated duct system or one with leaks can result in up to 30% energy loss. We use inspection cameras and smoke tests to spot thermal loss areas, which we correct on the spot.
Step 10: Maintenance Report and Recommendations
After every annual maintenance visit, we provide a detailed report, outlining the work done, parts to monitor, and our personalized recommendations to improve your system’s energy efficiency. This documented follow-up is essential for planning your HVAC budget over the medium and long term.
Field Testimonial: Complete Maintenance in Laval
Last November, we carried out a full maintenance service on a 120,000 BTU Lennox central system in a logistics warehouse in Laval. The client was dealing with major temperature fluctuations in certain zones. Upon inspection, we found a failure in the secondary blower motor and significant dust buildup in the exchangers. By replacing the motor, cleaning the ducts, and adjusting the central thermostat, we reduced their electricity bill by 18% over the following three months, while also improving employee comfort.
