Rectangular Duct Sections
Straight duct sections are a constant RFQ item because they anchor trunk and branch layouts across commercial mechanical packages.
First-wave acquisition
Commercial HVAC ductwork and fittings built from drawings and ready for install.
CMF turns drawings, markups, and project notes into fabricated HVAC parts that move cleanly from quote to production without extra handoff churn.
Commercial HVAC / mechanical project work only. Not residential service calls, emergency repair, or consumer replacement.

Frequent parts
Common HVAC parts sent out for pricing
These are the recurring light-gauge parts commercial HVAC teams most often break out into quote packages.
Elbows And Offsets
Elbows and offsets solve the field realities around structure, equipment, and crowded ceiling space.
Reducers And Transitions
Reducers and square-to-round transitions show up anywhere duct sizes change between mains, branches, or equipment connections.
Supply And Return Plenums
Plenums are standard package items around RTUs, AHUs, and larger commercial air-distribution layouts.
Collars, Taps, And Takeoffs
These connection parts turn larger trunk sections into buildable branch takeoffs and field-ready assemblies.
Roof Curbs, Drain Pans, And Access Parts
Accessory pieces around penetrations and equipment support are often priced with the main package, especially where weather and maintenance matter.
Commercial package snapshot
Before you send a mechanical package
Scope, drawing readiness, and release handling are usually what decide whether a package moves forward.
The main questions are whether the package fits and whether CMF can quote cleanly from the information you have today.
- Package types
- Duct runs, plenums, transitions, fittings, and accessory pieces tied to commercial mechanical jobs
- Material handling
- Galvanized, stainless, and aluminum depending on corrosion, cleanliness, and project-spec context
Most mechanical packages are still moving when pricing starts, so the key question is what is enough to get a quote moving.
- Enough to quote
- Partial drawing sets, markups, risers, equipment schedules, and branch details are all useful inputs
- Clarification style
- Missing dimensions or assumptions get tightened during review instead of forcing a restart
Once the scope fits, the next question is how the package will be grouped, released, and delivered.
- Quote speed
- Commercial quote response within 24 hours
- Package handling
- Bundles can be organized by release, package, or site sequence with GTA and Ontario delivery support
If the package is still coming together, start with what you have and tighten the details through review.
Project fit
What belongs on CMF's side of the HVAC package
Use this section as a fast scope check before you send drawings through the quote flow.
Best fit for CMF
- Commercial ductwork packages, plenums, transitions, fittings, and accessory sheet metal tied to project drawings.
- Marked-up plans, risers, schedules, and partial mechanical sets that are far enough along to review for fabrication.
- Galvanized, stainless, or aluminum parts that need fabrication and delivery support without adding another vendor handoff.
Usually out of scope
- Residential service calls, emergency repair, and consumer replacement work.
- Field installation, balancing, startup, or on-site mechanical service.
- Maintenance requests that do not yet have a defined fabrication package or drawing context.

Existing quote flow
Send HVAC drawings or markups for a quote
Send drawings, markups, or project details through the standard quote form. CMF will review the package around ductwork, plenums, transitions, fittings, and related mechanical parts.
- Partial drawing sets and markups are enough to start.
- Residential service and emergency repair remain out of scope.
- Commercial-only scope keeps the request clear.

Project FAQ
HVAC / Mechanical FAQ
These are the usual questions that come up before a mechanical package goes out for pricing.
Can I send partial HVAC drawings or only marked-up plans?
Yes. Partial drawing sets, marked-up PDFs, riser sketches, and equipment schedules are enough to start. You do not need a fully issued package before asking for pricing.
What details help you quote ductwork and fittings accurately?
Dimensions, material, gauge, connection style, insulation or finish requirements, and any delivery phasing notes help. If some of that is still open, CMF flags the gaps during review instead of bouncing the package back.
Do you only quote large duct packages?
No. CMF can quote full duct packages or smaller batches of plenums, reducers, collars, access parts, and rooftop accessories when they are tied to commercial project work.
Do you install on site or handle field service?
No. CMF handles fabrication and delivery support only. Residential service, emergency repair, and installation labor stay out of scope.
Can accessory pieces like curbs, drain pans, or takeoffs be included with the main package?
Yes. Those accessory parts are usually easier to quote and release when they stay tied to the main mechanical package instead of being split into disconnected one-offs.
