Maximize the lifespan and performance of your air conditioning system with professional maintenance
When it comes to residential or commercial air conditioning in metropolitan areas like Montréal, Laval, Longueuil, the South Shore and the North Shore, many homeowners and property managers focus mainly on buying a high-performance unit. However, what many people overlook is that annual air conditioning maintenance is one of the most cost-effective steps you can take to protect your investment, maintain consistent comfort, and avoid unnecessary long-term expenses.
At AirGreen, we’ve seen dozens of air conditioning systems break down prematurely simply due to lack of maintenance. In contrast, our regular customers who invest in rigorous annual HVAC maintenance enjoy more efficient, longer-lasting, and more energy-efficient systems.
Preventive maintenance: a wise investment to avoid major costs
A wall-mounted, central, or multizone air conditioning system runs for hundreds of hours each summer. Naturally, this leads to an accumulation of dust, pollen, mold, and sometimes even grease in internal components, filters, and coils. Without maintenance, these issues compromise:
-
Energy performance: a dirty unit can consume up to 30% more electricity.
-
System lifespan: extra wear and tear leads to premature breakdowns.
-
Indoor air quality: clogged filters spread allergens and contaminants.
-
Comfort: poor airflow or inconsistent temperatures affect your well-being.
Annual maintenance by AirGreen prevents these problems by intervening before they become critical and expensive.
What’s included in an AirGreen annual maintenance service?
Our certified HVAC technicians follow a detailed and customized process based on your specific unit model:
-
Thorough cleaning of the indoor unit (evaporator, filters, blower)
-
Inspection and cleaning of the outdoor unit (condenser, fins, fan)
-
Refrigerant level check (R-32, R-410A or R-454B depending on the system)
-
Measurement of pressures, amperage, and operating temperatures
-
Leak detection, corrosion check, and inspection for abnormal wear
-
Antibacterial disinfection if needed
-
Personalized recommendations based on usage, insulation, and property layout
The service is fully documented, and each client receives a clear report on the condition of their system.
Real-life examples: actual savings in Montréal and Laval
In Villeray–Saint-Michel–Parc-Extension, a customer contacted us after noticing an unusually high electricity bill. His Gree system, installed three years prior, had never been serviced. During our visit, we found a completely clogged filter and a condenser covered in plant debris. After our full maintenance, his energy consumption dropped by 27% the following month.
In Laval, a condominium equipped with Sharp ZU1 wall-mounted air conditioners opted for an annual maintenance contract with AirGreen. The result: no breakdowns over three summers, stable energy use, and satisfied co-owners.
Government grants? No—but guaranteed savings
Unlike wall-mounted or central heat pumps that qualify for LogisVert or Chauffez Vert rebates, maintenance services are not eligible for government financial assistance. However, this is still one of the most cost-effective expenditures in the long run. A compressor failure, for example, can cost between $1,000 and $2,000 – whereas an annual maintenance service ranges from $150 to $250 depending on the unit type.
Maintenance also protects your manufacturer’s warranty
Many manufacturers – Fujitsu, Gree, Goodman, Bosch, etc. – require annual maintenance by a professional to keep the warranty valid. Neglecting this could cost you years of coverage, which can be very expensive if a failure occurs.
At AirGreen, we provide written proof of every maintenance visit, properly documented for your records and for any future warranty claims.

Simple actions to take between professional maintenance visits

Never fully seal the outdoor unit during winter

Avoid using your A/C in excessively low outdoor temperatures
