Why trusting professionals like AirGreen for your HVAC maintenance changes everything
When it comes to heat pumps, wall-mounted air conditioners, ventilation systems, or central heating, one truth remains: regular maintenance is essential. However, not all maintenance is created equal. In the Greater Montréal, Laval, Longueuil, North Shore, and South Shore regions, many property owners still hesitate between doing it themselves or calling in experts like AirGreen. Today, we shed light on the real differences between DIY maintenance and professional maintenance, backed by real service calls carried out by our team.
The common mistake: thinking “cleaning” an HVAC system is easy
Some clients contact us after attempting to clean their wall-mounted heat pump or central air conditioner themselves, thinking that wiping it down or using a bit of soap is enough. Unfortunately, these superficial attempts often mask serious problems: mold buildup, clogged ducts, performance loss, and even premature system failures.
Take the recent example of a client in Brossard who cleaned their Gree Extreme 18,000 BTU wall unit themselves. Despite their efforts, the house remained uncomfortably humid and energy bills kept climbing. Once on-site, our team fully disassembled the unit, accessing the coils, condensation drain, and fan motor. The result: invisible bacterial growth and early signs of corrosion that only a deep, professional cleaning could treat.
The key differences between DIY and AirGreen professional maintenance
Visual inspection VS full technical diagnostics
An untrained eye may miss early warning signs of a technical issue. At AirGreen, each visit includes a comprehensive check of internal components, refrigerant levels, performance parameters, duct insulation, and more. Our technicians follow a strict inspection checklist tailored to each brand: Fujitsu, Gree, Lennox, Bosch, Goodman, etc.
Surface cleaning VS deep cleaning
Our service calls in Laval and on the North Shore often show just how limited DIY cleaning can be. Our teams perform high-pressure coil washing, antibacterial disinfection, and condensate tray cleaning. For example, during a recent job in Terrebonne, we removed over half a litre of buildup from a central Arcoaire system, invisible to the customer.
No specialized tools VS professional-grade equipment
A basic vacuum simply won’t cut it. Our technicians are equipped with dry steam machines, HVAC-approved cleaning products, duct inspection cameras, and vacuum pumps. These tools dislodge deep-seated dirt without damaging components.
Tangible impacts on performance and energy savings
Our post-service follow-ups show it clearly: professional maintenance reduces energy consumption by 15 to 30%, improves comfort, and extends equipment life. In Longueuil, a client with a Bosch BOVA central system saw their monthly bill drop by $48 after a complete maintenance visit—simply because airflow was restored to 100%.
DIY maintenance: the real risks you shouldn’t ignore
Here are a few situations we’ve fixed after DIY maintenance went wrong:
-
Clogged drain causing water damage in a condo in Montréal (Fujitsu KZAH wall-mounted heat pump).
-
Misplaced filter that damaged the fan motor of a Goodman system in Laval.
-
Unchecked capacitor, leading to a full system shutdown during a heat wave in Repentigny.
