Duct Masters doesn't just clean visible vents. We service the full path your air travels — from ducts and furnace components to dryer vents, bathroom exhaust, and indoor air quality testing.
Our core service
When vents aren't maintained, dust, pollen, and mold spores build up inside your duct system — and every time your furnace or AC runs, that contamination circulates through the air you breathe.
We use negative-air source removal with proper containment: all vent covers removed and sealed, all main ducts cleaned, plus furnace and connected components. Our DustCheck™ is included on every job.
Duct & HVAC system
These services target the components that move conditioned air through your home — often bundled into our duct cleaning packages.
Your furnace blower pushes air through every room. When the blower wheel and housing collect dust, airflow drops — and whatever's on that blower gets distributed through your ducts.
Budget operators often skip this step. We include blower cleaning as part of a complete system approach, not an optional add-on surprise at the door.
Dirt blocking your evaporator coil fins forces your AC to work harder, reduces cooling output, and can circulate mold through your home.
Professional coil cleaning restores airflow — especially important before and after Montreal's cooling season.
Your outdoor condenser expels heat from your home. When the exterior coil is clogged with dirt, leaves, and debris, your AC runs longer, costs more, and wears out faster.
We clean the exterior coil using methods that protect the fins and restore proper heat transfer.
Wall-mounted mini-splits and through-wall units accumulate dust and biofilm on the head unit, filters, and connecting paths — reducing efficiency and air quality in the rooms they serve.
Ideal for condos, additions, and homes with room-by-room HVAC instead of central ducts.
Ventilation & safety
These services address fire risk, moisture, and fresh-air ventilation — problems that duct cleaning alone won't solve.
Lint builds up inside your dryer vent line — not just the lint trap. As many as 15,000 house fires start in the laundry room each year when lint ignites.
We clean the full vent run, restoring airflow and cutting fire risk. Be smart, not sorry.
When dust blocks your bathroom exhaust fan or duct, humid air stays after showers — creating conditions for mold on walls, ceilings, and grout.
We clean the fan housing, blades, and exhaust path so ventilation works as designed.
Heat recovery and energy recovery ventilators run continuously — bringing fresh air in and carrying dust, pollen, and outdoor debris through the core and ductwork.
Common in newer Montreal homes, and often missed during routine maintenance.
Air quality & add-ons
Cleaning is step one. Testing and protection help you understand — and improve — what you're actually breathing at home.
UV-C lights in your HVAC system help reduce mold, bacteria, and microbial growth on coils and in the airstream. Most effective on a system that's already been properly cleaned.
We install and position units for maximum coverage within your duct or coil chamber.
Tobacco residue, aerosol by-products, cleaning chemicals, and everyday particulates accumulate indoors — often without anyone realizing it.
Tell us about your setup — we'll recommend the right services with upfront, flat-rate pricing. No surprise add-ons at your door.
