Unexpected Guests in Your HVAC System
In Greater Montreal’s humid summers and freezing winters, your HVAC unit works overtime. But sometimes the source of rattles, squeaks or drops in efficiency isn’t mechanical—it’s wildlife. A recent case saw a homeowner baffled by clanking sounds and lukewarm air. Upon inspection by Climate Solutions, the culprit was a rodent that had infiltrated the compressor housing.
How Critters and Debris Harm Your HVAC
1. Nesting in Ductwork
Rodents and squirrels find duct channels inviting for shelter from Montreal’s climate extremes. Once inside, they chew insulation, wiring and metal, reducing airflow and risking fire hazards. Seal gaps around vents, have professional HVAC maintenance Montreal inspections, and install rodent guards to keep ducts pest-free.
2. Vulnerabilities of Outdoor Units
Even with its protective grille, your outdoor condenser can attract mice, birds and snakes seeking warmth and shelter. These intruders can gnaw electrical wiring and clog drainage lines. Maintain a clear perimeter by removing leaves and weeds, and fit a mesh screen to defend against unwanted visitors.
3. Bird Nests and Blocked Airflow
Birds often build nests in tight crevices of HVAC housings. Grass, twigs and debris block vents, forcing your system to work harder and raising energy bills. Installing lightweight mesh guards and scheduling regular cleanouts by a professional HVAC installation Montreal specialist can keep nesting materials at bay.
4. Indoor Contaminants: Pet Hair & Dander
In many Montreal households, pets are family. But hair, dander and dust accumulate in filters, hindering airflow and straining components. Replace or clean filters every 2–3 months—more often if you have shedding pets—to maintain energy efficient HVAC performance.

Routine checks are essential, especially in our varied climate. Follow these tips:
- Inspect vents and duct seams for gaps.
- Clear vegetation around outdoor units.
