Duct Cleaning Quotes in Calgary: How to Compare What’s Included

Before choosing between residential duct-cleaning quotes in Calgary, clarify whether they address the same reason for cleaning and include the same work. Then compare the written totals and home-protection arrangements. A lower price alone does not tell you whether the offer covers less work or better fits what you need.

What observation supports recommending cleaning?

Ask each provider: “What have you observed that supports cleaning, and can you show me?” Start here rather than assuming that a quote establishes the need for the service.

The US EPA’s residential guidance recommends asking providers to show the contamination that would justify cleaning. It says the evidence does not justify claims that duct cleaning prevents health problems, universally improves indoor air quality or is routinely necessary. This is US residential evidence guidance, not Alberta regulation.

Write down the observation separately from the work being recommended. If a recommendation relies only on a general statement about dust or health, ask what supports cleaning in your particular circumstances. If the reason remains unresolved, make that your next discussion rather than choosing a package on price alone.

Which work is included, excluded or still unclear?

Ask: “Which parts of my residential duct system are included, what work will be done, and what is excluded?” Request enough detail to compare the proposals without having to interpret unfamiliar service labels.

The EPA recommends comparing written estimates and agreeing on the scope and total cost in writing before work begins. Put the descriptions side by side. Where the wording differs, ask the providers whether it describes equivalent work; do not assume that a longer description necessarily covers more.

Have separately offered work identified clearly. Treat an unmentioned item as unresolved, not included or excluded. If one quote leaves out work you want, ask for a revised proposal. If you do not want that work, keep the narrower scope in the comparison rather than adding services solely to make the quotes match.

Is the amount an estimate or an agreed total?

Ask: “Is this amount an estimate or the agreed total for the written scope, and what assumptions does it depend on?” Keep the answer attached to the quote so the amount and its conditions stay together.

If either amount is provisional, ask what information remains outstanding and whether it could change the written scope or total. Request clarification of anything described as additional or separately charged, including whether you have chosen to include it.

Also ask how any proposed change to the work or price would be presented for your approval. This is a point to settle with the provider, not a procedure to assume. Before work begins, use the written scope and total—not a verbal summary—as your reference for what you have agreed.

What access and home-protection arrangements are proposed?

Ask: “Which areas need access, what should I prepare, and how will you protect the home from contamination during the work?” These answers give you practical details to consider alongside the scope and price.

The EPA suggests asking how the provider will protect the home from contamination and about its experience with similar systems. Ask for an explanation relevant to your system rather than inferring a method or level of experience from the quote.

Note any preparation assigned to you and flag anything you cannot accommodate. For example, if you are unsure whether you can provide the requested access, describe the constraint and ask the provider to clarify the arrangements before scheduling. Record the answer with the proposal.

Make a short difference sheet before booking

Instead of copying both quotes in full, create one entry for each meaningful difference. Use this compact worksheet:

• Difference: Copy the relevant wording from each quote, labelled by provider. If something is absent, write “not stated.”
• Your preference: Note whether you want the work, need a clearer explanation or cannot accommodate a proposed arrangement.
• Open point: Write the exact clarification needed and which provider needs to answer it.
• Resolution: Add the provider’s written answer and identify the updated quote or scope it belongs to.

This leaves you with a focused record of what actually separates the offers. Keep unresolved items visible rather than filling gaps with assumptions.
