What should a duct or dryer vent quote include?
Ask for a written scope that explains the work in plain language. The goal is to compare the same parts of each quote, not just the bottom line.
- Which components are included, such as supply ducts, returns, registers, or HVAC components
- What is excluded from the quoted price
- How the home or building will be protected during work
- How debris will be collected and removed
- How access openings will be closed afterward
- How additional work is approved if unexpected conditions are found
How to verify a contractor
Ask for qualifications, insurance, and any applicable license. If chemicals are proposed, request the safety data and ask why they are needed for your system.
Licensing rules vary by location, so verify the requirements that apply to your property. The estimate should show who is doing the work and what insurance and qualifications they carry.
What access details belong in a quote
Access assumptions should be written down. If a quote assumes easy attic or crawlspace entry and the actual route is tighter, the price or work plan may change.
- Room access around registers and returns
- Attic, crawlspace, basement, or utility space access
- Roof or wall termination for dryer vents
- System count and approximate layout
- Tenant or occupant coordination for rentals or multi-unit buildings
How to compare two cleaning quotes
Compare the same categories across each quote. A lower line item may leave out protection, collection, or a completion check that the other quote includes.

| Quote detail | What to compare | Why it matters |
|---|---|---|
| Scope | Which ducts, registers, and components are included | Defines what work is actually being priced |
| Method | Agitation, negative-pressure collection, and equipment type | Shows how debris will be removed and contained |
| Protection | Floor, surface, and occupant protection | Reduces mess and risk during the job |
| Collection | How debris leaves the system and the home | Confirms cleanup is part of the plan |
| Completion check | Visual inspection and access closure | Provides a clear finish point |
| Exclusions | Repairs, modifications, or extra systems left out | Prevents surprise costs later |
| Additional work | How changes are approved before proceeding | Keeps you in control if conditions change |
