Sales Toolkit for HVAC and Mechanical Contractors: Win Work From Builders and GCs
HVAC and mechanical contractors win work from builders and general contractors by reaching them before the HVAC package is awarded, sending a bid that is easy to compare and following up as the build moves. The window runs from about 20% of the way through the build to about 45%, with the last realistic approach at about 55%. Builtie, a sales automation platform for construction trades, counted 52,355 HVAC projects inside that window across 25 markets on October 9, 2026 and finds each builder's decision maker; this toolkit has the timing, copyable bid and follow-up templates, and where the work is.
The same four steps, whether the buyer is a builder, a designer, an owner or a company you want to acquire.
How HVAC and mechanical contractors win work from builders and GCs
- Find the projects early, on building permits: most private HVAC work is awarded by the builder or general contractor without a public bid.
- Call inside the window: from about 20% of the way through the build to about 45%, with the last realistic approach at about 55%.
- Reach the person who buys HVAC work. The general contractor or builder awards the mechanical package; on commercial work a mechanical engineer designs it first, and on multi-unit residential the developer often sets the equipment standard.
- Send a bid that is easy to compare: scope, price and validity, exclusions, allowances and a schedule tied to the build.
- Follow up when the build moves, not on a timer, and ask for the builder's next project when this one is decided.
When HVAC work gets picked
Builtie times HVAC work from about 20% of the way through the build to about 45%, with the last realistic approach at about 55%. That is when the structure is up and the mechanical, electrical and plumbing packages are awarded.
Tap a stage. The highlighted stage is where HVAC is typically awarded.
The window is a share of the build, so its dates depend on how long the build runs. Builtie's own estimate sets the build length from the declared construction value on the permit; in weeks after construction starts:
| Declared value | Window opens | Window closes | Last realistic approach |
|---|---|---|---|
| $250k to $1M (7-month build) | week 6 | week 14 | week 17 |
| $1M to $5M (13-month build) | week 11 | week 25 | week 31 |
| $5M to $25M (20-month build) | week 17 | week 39 | week 48 |
| $25M to $100M (30-month build) | week 26 | week 59 | week 72 |
Check one project: the award window calculator takes a trade and a stage (or months since the permit was issued) and says whether HVAC work is before, inside or past its window.
Bid cover note template
Send this with the price. It answers the questions an estimator asks before comparing bids: what is in, what is out, what is an allowance, and when you can start. Replace everything in [brackets].
Subject: [Project address]: HVAC price from [Your company] Hi [First name], Attached is our HVAC price for [project address], based on [drawings / specification, revision and date]. Scope: HVAC supply, installation, testing and balancing per mechanical drawings [sheets]. Price: $[amount] [plus tax], valid until [date]. Excludes: power wiring to equipment; roof curbs and openings by others; gas service from the utility. Allowances: equipment of equal performance where a model changes; [number] extra diffusers at $[rate] each. Schedule: HVAC work is usually decided between about 20% and 45% of the build. We can hold [crew / production slot] for [weeks or dates] if we hear back by [date], and will confirm again when the structure is up and the rough-in start is set. Why us: [show load calculations, equipment lead times, energy-code compliance and duct coordination while the frame is still open]. One question: [the one thing that would change the price, such as a spec choice or a phasing date]. [Your name] [Company] | [phone] | [email]
Three-touch follow-up and a LinkedIn note
Three emails, each tied to the project rather than to a calendar: the first a few days after the bid, the second when the structure is up and the rough-in start is set, the third before the window closes at about 55% of the build. The LinkedIn note is for the estimator or project manager you have not met.
Subject: Re: [Project address]: HVAC price Hi [First name], Checking the HVAC price for [project address] reached you and reads clearly. If anything in the scope or the exclusions does not match your other bids, tell me and I will line it up so you are comparing like for like. [Your name] | [phone]
Subject: [Project address]: HVAC schedule Hi [First name], I see [project address] is moving: the structure is up and the rough-in start is set. That is usually when HVAC work gets decided. We are still holding [crew / production slot] for [dates]. Can I get 10 minutes this week to confirm the scope, or is there a revision I should price? [Your name] | [phone]
Subject: [Project address]: releasing our HVAC slot Hi [First name], We will release the [crew / production slot] we held for [project address] on [date] unless you need it. If HVAC work has been awarded, no problem: what is your next project, and when does it go out to price? [Your name] | [phone]
Hi [First name], saw [Company] has [project address] in the works. We do HVAC work for builders and GCs in [city] and price to your schedule. Worth a look before HVAC work is awarded? [Your name]

Frequently asked questions
How do HVAC and mechanical contractors win work from builders and general contractors?
By finding projects early on building permits, reaching the builder or general contractor while the HVAC package is still open (from about 20% of the way through the build to about 45%, with the last realistic approach at about 55%), sending a bid that states scope, exclusions, allowances and schedule, and following up as the build moves.
When is HVAC work awarded on a new building?
Builtie times HVAC work from about 20% of the way through the build to about 45%, with the last realistic approach at about 55%. The general contractor or builder awards the mechanical package; on commercial work a mechanical engineer designs it first, and on multi-unit residential the developer often sets the equipment standard.
What should an HVAC bid cover note include?
The drawings and revision it is based on, the scope (HVAC supply, installation, testing and balancing per mechanical drawings [sheets]), the price and how long it holds, what it excludes, the allowances, and a schedule tied to when HVAC work is decided.
How should I follow up on an HVAC bid?
Three touches tied to the project: a few days after sending, when the structure is up and the rough-in start is set, and before the window closes at about 55% of the build. If the package is gone, ask for the builder's next project.
Is Builtie a CRM?
No. A CRM stores the contacts and deals you already have. Builtie is sales automation: it finds the projects from building permits, times each one to your trade's award window, finds the decision maker and runs the LinkedIn and email outreach. Most customers keep their CRM or job-management tool for the work they win.
What does Builtie cost?
Starter is $79 per seat per month (CAD) for 20 projects; Growth is $99 for 50 projects and adds LinkedIn and email outreach. There is a 7-day free trial with 10 projects.
