Indoor Air Quality
Clear out the dust, debris, and allergens hiding in your ductwork — for better airflow and healthier indoor air.
Ductwork collects a decade of construction dust, drywall residue, pet dander, and pollen, and every time the blower starts it puts some of that back into the rooms where your family sleeps. In Toronto homes with finished basements, past renovations, or a recent equipment change, the accumulation is usually far worse than homeowners expect.
NorthPoint's duct cleaning is a full negative-pressure process, not a shop vac at the register. We seal the system, put it under negative pressure with a high-capacity HEPA-filtered vacuum, then agitate every supply and return branch with rotating brushes and compressed-air whips so the debris is pulled out of the house rather than pushed further down the run. Registers, the return plenum, and the blower compartment are cleaned as part of the job.
While we are in there, we are also inspecting: disconnected branches in the joist space, crushed flex duct, leaking joints in unconditioned areas, and undersized returns are extremely common in older GTA homes, and each one quietly costs you comfort and money every month the system runs.
Cleaning makes the most sense after a renovation, after buying a home, when household allergies flare up, or when you can see dust building on the register grilles within days of wiping them. We will give you a straight answer about whether your system actually needs it.

Disconnected branches dumping conditioned air into a joist space, crushed flex duct, leaking joints in unheated areas, and undersized returns are extremely common in older GTA homes. Each one quietly costs you comfort and money every month the system runs, and each one is far cheaper to fix while the system is already open.
After a renovation, after buying a home, when household allergies flare, or when dust reappears on the register grilles within days of wiping them. If your ducts do not need it, we will tell you — there is no value in cleaning a clean system.
Where mould or persistent odours are present, an appropriate antimicrobial treatment can be applied after cleaning. Where leakage is the real problem, sealing the duct joints delivers far more than cleaning ever will. We recommend based on what the inspection shows.
“We switched from another plumbing and HVAC service to NorthPoint and we couldn’t be more happy. Their prices are more affordable, their people more knowledgeable, and they get to you fast — especially important when your AC blows out in the middle of summer!”
— B. Parker
“The techs are prompt, friendly and trustworthy. They are knowledgeable and professional, and they explain what they are doing instead of just handing you a bill. I highly recommend them.”

“Showed up the same afternoon and explained everything he was doing. Very thorough, polite and professional — and cleaned up the whole area afterward.”

Duct cleaning is worth considering if:
A thorough duct service addresses the whole air path:
Toronto's older homes often have decades of accumulated debris in their ductwork, while new builds frequently carry construction dust from day one. Both benefit from a proper cleaning — especially for households with allergies, pets, or recent renovations.
For most homes, every few years is plenty — sooner after a renovation, a pest issue, or if anyone has significant allergies.
It can reduce recirculated dust and allergens, especially when paired with good filtration.
Cleaner ducts and a clearer blower can improve airflow and efficiency, though savings vary by home.
A typical home takes a few hours depending on system size and duct layout.
Not every home does. We give an honest assessment rather than a blanket recommendation.
Yes — duct cleaning pairs well with better filters, air purifiers, or a humidifier.
