Commercial Duct Cleaning: A Canadian Property Manager’s Scope Checklist

For post-renovation commercial duct cleaning, choose by location, project scope, access needs and required completion evidence; the supplied pages do not support a best-overall or cheapest provider.[1][2][3][4][5][6]

Compare providers by renovation need

All capabilities, credentials and experience below are vendor-reported. The source pages are undated, so their present status cannot be established from the supplied evidence.[1][2][3][4][5][6]

• Alberta Furnace Cleaning Edmonton — Potential post-renovation fit: New construction, smoke or flood restoration, and large institutional or industrial properties; Vendor-reported capability: Lists truck-mounted and portable commercial equipment, projects ranging from offices to airports and manufacturing facilities, COR certification, and NADCA-certified supervision.[1]; Important unknown: Contract and cancellation terms are not verified.[1]

Ottawa area — Potential post-renovation fit: Projects requiring cleanup and before-and-after pictures; Vendor-reported capability: Offers commercial duct cleaning in Ottawa and surrounding communities and advertises complete cleanup and before-and-after pictures.[2]; Important unknown: Project limits, warranty and contract terms are not verified.[2]
• Advanced Air Quality Ottawa — Potential post-renovation fit: Robotic inspection, coil cleaning or several exhaust-system services; Vendor-reported capability: Lists camera-equipped robotic equipment, coil cleaning, and make-up-air, bathroom-exhaust and dryer-vent services.

It advertises a 90-day service-quality warranty.[6]; Important unknown: Warranty exclusions and claim procedures are not verified.[6]

Can the providers be compared on price?

No. None publishes a comparable commercial base price, minimum charge, per-vent rate, per-square-foot rate or total-price range.[1][2][3][4][5][6]

Alberta Furnace Cleaning provides a written quote after an assessment, and Integral Air offers a quote request.[1][4] Ottawa Duct Cleaning offers a free telephone estimate, while Advanced Air Quality offers a free commercial consultation or estimate.[2][3] Gravity advertises custom estimates, fixed pricing and discounts but gives no rate or discount formula.[6] Steam Dry Canada promotes no hidden charges and no-interest financing, but its supplied page does not disclose service prices, financing eligibility, the lender or repayment terms.[5]

Tax treatment, travel charges and binding quote-validity periods also remain unverified. Compare only written quotes covering the same systems, areas, equipment, documentation and exclusions.[1][2][3][4][5][6]

What the site assessment and quote should cover

Ask the estimator to record the service area, extent of soiling, specific concerns, requested services, equipment needs, parking and building access—the factors Alberta Furnace Cleaning says it assesses.[1] The assessment should also address building size, ductwork complexity, clearance around vents and registers, and access to HVAC equipment; Integral Air identifies these as factors affecting preparation and duration.[4]

The written scope should identify:

• the HVAC systems, duct sections and property areas included;
• the renovation or restoration debris to be removed;
• the inspection method and cleaning equipment;
• any access openings, sealing or repair work;
• cleanup, debris disposal and completion evidence; and
• whether each item is included, excluded or separately priced.

Itemize optional systems such as coils, rooftop units, make-up-air and bathroom exhaust so quotes cover equivalent work.[1][3][4][5][6] This comparison concerns general ventilation after renovation. Kitchen grease extraction and hazardous-material remediation require separate specialist scopes.

Which providers document the work?

Ottawa Duct Cleaning advertises before-and-after pictures.[2] Gravity says before-and-after photos or video confirmation are available on request, so its media should not be assumed to be automatic.[6]

Advanced Air Quality describes robotic cleaning and inspection equipment with built-in cameras.[3] Integral Air advertises camera-equipped robotic cleaning and inspection for difficult-to-access ductwork.[4] Neither page confirms whether customers receive recordings, labelled images or a written inspection report.[3][4]

Require the quote to specify:

• whether photos or video are standard or optional;
• which ducts, systems and concealed areas will be recorded;
• how each location will be identified;
• the file format and delivery timing; and
• whether a final inspection report is included.

The supplied pages do not establish these details.[2][3][4][6] Gravity also reports conducting a final inspection and applying a dated service sticker.[6]

How much weight should credentials and claims carry?

Alberta Furnace Cleaning reports COR certification and says every commercial cleaning is supervised by a NADCA Certified technician. Advanced Air Quality describes itself as NADCA Certified.[1][3] Gravity says it is bonded and insured and that its technicians hold HVAC-related certifications or licences, but it does not name those credentials or disclose insurance limits.[6]

Ask shortlisted providers for current certificates, proof of insurance and the qualifications of the technician assigned to the project. The source pages have no publication or update dates, so they do not establish present credential status.[1][3][6]

NADCA’s commercial checklist describes verification of particulate cleanliness across the components in scope; it does not establish whether microbial or hazardous-material contamination is present.[7] Specify the contractor’s verification method and how disputed or inconclusive results will be addressed. NADCA is industry guidance, not automatically a Canadian legal requirement.

The reviewed provider pages do not establish independent health or energy-saving outcomes. Select the cleaning scope from a site assessment rather than assuming routine cleaning or a health benefit is necessary.[1][2][3][4][5][6]

Plan access and scheduling

Integral Air says commercial work may take a few hours, a full day or longer depending on building size and ductwork complexity; it also says off-hours service may be arranged.[4] Alberta Furnace Cleaning offers Monday-to-Saturday booking and may assign multiple crews to larger projects.[1]

• Clear areas around vents and registers and provide access to HVAC equipment, following project-specific instructions.[4]
• Confirm parking, loading, equipment routes and access restrictions.
• Record the work window and any after-hours charge in writing.
• Confirm whether an HVAC or building shutdown is required; the supplied pages do not establish shutdown requirements.[1][2][3][4][5][6]

What to verify before signing

• Scope and price: List included systems and areas, total price, taxes, minimum charges, travel, parking, equipment, access creation and sealing, debris disposal, cleanup and completion records. The vendor pages do not publish comparable rates or confirm these potential charges.[1][2][3][4][5][6]
• Payment: Confirm deposits, payment milestones and the final due date. Only Gravity states that payment is due after completion and lists cheque, e-transfer, credit card, debit card and cash as accepted methods.[6]
• Timing and changes: Obtain cancellation and rescheduling fees, after-hours surcharges, quote validity, service deadlines and shutdown requirements in writing. These terms remain unverified across the supplied sources.[1][2][3][4][5][6]
• Risk and exclusions: Request insurance limits, worker-clearance documents, and hazardous-material or asbestos exclusions. The supplied pages do not verify these details.[1][2][3][4][5][6]
• Warranty: Obtain the claim procedure, coverage period, exclusions and remedy. Gravity advertises a 90-day service-quality warranty, while Steam Dry advertises a satisfaction guarantee without procedural details in the supplied page.[5][6]

Base the final selection on a site-specific written scope, total price, exclusions and completion evidence. If financing is proposed, obtain its full terms separately; it is not part of the service comparison.
