Start with the decision
Write the HVAC scope around named deliverables, the drawings that describe them and the interfaces with other trades. Identify whether the HVAC package concerns equipment, distribution, controls or a combination. Do not assume that a mechanical installation proposal includes every related trade. Use the worksheet below to expose missing information before requesting a firm quotation.

Define each package boundary
| Deliverable | Input to include | Boundary to settle |
|---|---|---|
| Equipment | equipment schedule and replacement or new-installation scope | supply, delivery, lifting and startup responsibilities |
| Distribution | duct or piping boundaries and approved drawings | insulation, supports and access provisions |
| Controls and balancing | controls interface and testing responsibility | standalone controls versus integration and balancing |

Fill in the response, owner or source, and date checked. Keep unresolved items visible. The file contains planning prompts only; it does not calculate quantities or make an approval decision.
Put the checklist to work
- Attach the current drawing and specification references, and identify who may receive them. Separate issued information from items still awaiting approval.
- Assign electrical connections, controls integration, roof work and testing or balancing explicitly. Use included, excluded, by others or unresolved, with a named owner for unresolved items.
- Document assumptions about equipment availability, lifting access, power readiness and the agreed startup sequence. A target date is not a substitute for those inputs being available.
- Issue the same revision to all invited businesses. Record clarifications and circulate material changes before comparing proposals.
A scope gap worth discussing
Illustrative example — not a Build Accord client project
A rooftop equipment replacement is priced without roof-curb adaptation. Ask who carries that work and how it affects the lifting and weather-protection plan before treating the quote as complete.
Apply this to your decision: A scope sheet with deliverables, interfaces, exclusions and unresolved decisions that every invited business can price against.
Using this in the US and Canada
For a project in the United States
Record the state, local jurisdiction and actual service area. Confirm the project location and the scope of the business’s authority with the responsible project team. The U.S. Small Business Administration provides a starting point for business licensing resources.
For a project in Canada
Record the province or territory, municipality and actual service area. Use Canada’s permits and licences resources to locate relevant checks, including the linked BizPaL service. Confirm requirements for the actual activity and location.
For either market, state the currency, units and deadline time zone. This worksheet is general planning guidance, not a determination of licensing, procurement eligibility or technical compliance.
The next useful step
Continue with hvac invitation to bid checklist. For the other side of the conversation, see the hvac bid proposal guide.
Build Accord coordinates introductions between construction project teams and trade contractors. An inquiry starts a discussion of fit and availability; it does not guarantee a contractor, an invitation to bid or an award. These guides are not a listing of currently available crews or projects.
