Air Duct & Dryer Vent Cleaning in Richmond Hill, Ontario

Dusty or stale air in your Richmond Hill home can signal a buildup inside your ducts. Over time, dust, pollen, and debris settle inside your HVAC system, lowering air quality and airflow efficiency.

At City Duct Cleaning Inc., we’ve been serving Richmond Hill since our company’s inception in 1987, helping homeowners and businesses breathe cleaner, healthier air. Our certified technicians use HEPA-filtered vacuums and high-pressure air systems to remove contaminants safely and effectively. Call (416) 293-1800 for a free quote.

Why Richmond Hill Homes and Businesses Need Duct Cleaning

Richmond Hill’s mix of modern homes, condos, and commercial spaces relies on HVAC systems year-round. As air circulates, pet dander, lint, and allergens collect inside ducts and recirculate through your space, affecting comfort and health.

Left uncleaned, moisture buildup can lead to mould, musty odours, or uneven room temperatures — forcing your HVAC system to work harder, use more energy, and wear out faster. Regular professional cleaning addresses all of this (see the full list of benefits below).

Residential Duct Cleaning in Richmond Hill

We clean air duct systems in detached and semi-detached homes, townhomes and duplexes, and condominiums and apartment buildings throughout Richmond Hill, using HEPA-filtered vacuums and compressed air to remove dust, pet dander, and debris safely.

Commercial Duct Cleaning in Richmond Hill

We also serve Richmond Hill’s commercial side, including retail and office spaces, schools, medical centres, and warehouses. This work isn’t new to us — City Duct Cleaning has been a leader in new-home “builder job” duct cleaning since Richmond Hill’s building boom took off around 1990, cleaning the duct systems in thousands of new homes across the area’s subdivisions before homeowners took possession. It’s often surprising how much construction debris collects in a duct system before a home is even lived in, which is why many builders now include duct cleaning as a standard part of the new-home process.

Dryer Vent Cleaning in Richmond Hill

A blocked dryer vent restricts airflow, raises energy use, and increases fire risk. We offer dryer vent cleaning in Richmond Hill as a standalone service or alongside your duct cleaning appointment. For the full process and warning signs, see our dryer vent and duct cleaning page.

Our Duct Cleaning Process

Our Richmond Hill duct cleaning follows a consistent process:

1. Inspection — we check your vents, ducts, and furnace for dust buildup and airflow issues.
2. Vacuum setup — a truck-mounted vacuum creates powerful negative pressure to pull contaminants out.
3. Air agitation — each vent is cleaned with 250 psi compressed air to dislodge debris.
4. Main duct cleaning — air whips and snakes push dirt toward the vacuum for complete removal.
5. Furnace and coil cleaning — blower, plenum, fan, filter area, and AC coil, at no extra cost.
6. Duct sanitization (optional) — an EPA-approved antimicrobial treatment on request, to reduce odours and bacteria.
7. System testing — we reseal the system and test for smooth, balanced airflow.

Most residential appointments take 2 to 4 hours, depending on system size and accessibility.

Signs Your Air Ducts May Need Cleaning

• Dusty or stale-smelling indoor air

• Uneven temperatures from room to room

If what you’re noticing sounds more like a leak than dust buildup, see our guide on how to know if your air ducts are leaking.
