Improving comfort while reducing our environmental footprint: it’s possible thanks to one simple action that’s often underestimated — regular maintenance of air conditioning systems. At AirGreen, we firmly believe that a well-maintained system is not only more efficient, but it also plays a major role in reducing energy waste and preserving our environment. This article dives deep into this little-known reality while exploring the critical choices facing property owners in Montréal, Laval, Longueuil, the North Shore, and the South Shore: should you clean or replace your air conditioning system?
One simple service that changes everything: a hidden truth
Air conditioner maintenance isn’t just about removing dust. It’s a complete, technical, and ecological process. At AirGreen, we carry out full cleanings of wall-mounted units, central systems, and ventilation ducts, including:
-
High-pressure washing of the indoor and outdoor coils,
-
Antibacterial disinfection of the drainage trays,
-
Thorough cleaning of filters,
-
Degreasing of the blower wheels and fan,
-
Inspection of refrigerant levels and seal integrity on all connections.
These procedures not only ensure optimal performance, they also reduce electricity consumption by up to 30% in summer and extend the lifespan of HVAC systems.
Why replacing a still-functioning unit isn’t always the right choice
Many consumers, faced with a drop in performance or an unusual noise, assume it’s time to replace the system. But in more than 60% of the cases we encounter in Montréal and surrounding areas, a professional cleaning is enough to restore full functionality.
Case Study: Wall-mounted Gree air conditioner in Laval
A client in Laval recently contacted us about an 18,000 BTU wall-mounted Gree unit they believed was at the end of its life. The system was noisy, blowing lukewarm air, and their electricity bill had doubled since spring. After a full inspection followed by a professional cleaning, the unit returned to peak performance. Result: $0 spent on a replacement, immediate energy savings, and several more years of reliable operation.
The environmental cost of premature replacement
Replacing an air conditioning system without first attempting cleaning or thorough maintenance carries a heavy environmental cost:
-
Manufacturing a new unit (even one that’s Energy Star certified) generates an average of 210 kg of CO₂,
-
Partial recycling of old units is rarely optimal, especially when it comes to heavy metals, plastics, and refrigerants,
-
Shipping and packaging for new equipment significantly add to emissions from logistics.
At AirGreen, we prioritize a responsible approach: maintenance before replacement. We only recommend replacing a unit when there are major breakdowns, unrepairable leaks, or clearly outdated technology.
Good maintenance also means better health
Beyond energy efficiency, regular maintenance protects your health. Dirty systems become breeding grounds for bacteria, mold, and fine particles. In a humid climate like Greater Montréal, this can worsen allergy symptoms, asthma, and respiratory issues.
Our certified technicians perform deep cleaning, including treatment of internal components with eco-friendly products, to ensure flawless indoor air quality.
A smart maintenance schedule: the key to durability
At AirGreen, we recommend a complete service at least once a year, preferably in spring before the heat arrives. This visit helps:
-
Prepare your system for peak season,
-
Detect potential issues (minor leaks, clogged filters, unbalanced fans),
-
Maintain your manufacturer warranty, which often requires regular maintenance.
We also offer customized preventive maintenance plans, adapted to the realities of each customer (residential, multiplex, condo, commercial, or office).
Cleaning vs. Replacing: how to decide?
Cleaning is recommended if:
-
The unit is under 10 years old,
-
You notice a gradual drop in performance,
-
You hear unusual noises,
-
The unit is visibly dirty or emits odors,
-
Your energy bill increases for no apparent reason.
Replacement is advised if:
-
The unit is 12-15 years old or more,
-
Major repairs are needed (compressor, control board),
-
It uses an old R-22 refrigerant, banned for years now,
-
Your building’s energy needs have changed (renovations, extensions).

Client testimonial – Brossard, South Shore
“I thought I had to replace my old 9-year-old wall-mounted heat pump. The AirGreen technician recommended a full cleaning instead. Three hours later, it worked like new. Result: $200 spent instead of $4,500. Highly recommended.” — Ms. L., Brossard
