HVAC Subcontractor Proposal Template: 7 Must-Have Sections

If you are sending HVAC bids as a Word doc or a rough email, you are leaving money on the table. General contractors and building owners judge your professionalism before they ever pick up the phone. A clean, detailed proposal tells them you know what you are doing and that you will not be a problem on their job site.

This guide breaks down exactly what to include in a solid HVAC subcontractor proposal template. Use these sections every time and you will spend less time writing bids and win more of the ones you send.

1. Company Header and Contact Information

Put your business name, logo, license number, phone, email, and address at the top of every proposal. This sounds basic but a lot of subs skip it or bury it at the bottom.

GCs are juggling dozens of bids. Make it easy for them to call you. If your contact info is hard to find, they will just move on to the next sub.

2. Project Information and Bid Date

Clearly state the project name, address, and the date you submitted the bid. Also include the bid expiration date, typically 30 days is standard.

This protects you. Material prices change. Labor costs shift. A proposal without an expiration date can come back to haunt you months later when a GC tries to hold you to a number that no longer works.

3. Scope of Work

This is the most important section. Be specific about what you are doing and what you are not doing.

For HVAC subcontractors, a clear scope typically includes:

  • Equipment being installed (make, model, tonnage, SEER rating)
  • Ductwork type and square footage
  • Refrigerant line sets
  • Electrical disconnects and whips (if included)
  • Thermostat and controls
  • Startup and commissioning
  • Permits (state whether they are included or excluded)

If it is not written down, the GC will assume it is included. A detailed scope of work prevents change order disputes and protects your margin.

4. Itemized Pricing Breakdown

Lump sum bids lose deals. When a GC looks at a number with no backup, they get nervous. An itemized breakdown shows your price is fair and builds trust.

Break your pricing into categories like:

  • Equipment and materials
  • Labor hours and rates
  • Subcontracted work (if any)
  • Permits and inspections
  • Overhead and markup

Tools like TradeBid are built specifically for this. TradeBid lets HVAC subs generate itemized, client-ready bid PDFs fast, without messing around in spreadsheets or Word templates. You plug in your scope and numbers and it produces a professional document you can send the same day.

5. Exclusions and Clarifications

This section saves you from doing free work. List everything that is NOT included in your bid.

Common HVAC exclusions include:

  • Electrical rough-in beyond the disconnect
  • Gas line installation
  • Structural modifications for equipment placement
  • Asbestos or hazardous material remediation
  • Work outside normal business hours
  • Crane or lift rental

If you do not spell these out, a GC can point to your proposal and argue that your scope covers something it does not. Write it down and protect yourself.

6. Project Schedule and Lead Times

GCs need to plan their schedule. Tell them when you can start, how long the work will take, and if there are any equipment lead times they need to know about.

Right now, HVAC equipment lead times can stretch out significantly depending on the manufacturer and unit type. If a rooftop unit has a 14-week lead time, the GC needs to know that before they commit to a project timeline.

Being upfront about lead times actually builds credibility. It shows you have already thought through the logistics.

7. Terms, Payment Schedule, and Signature Block

Close every proposal with your payment terms and a place to sign.

Standard payment terms for HVAC subs often look like:

  • Net 30 on approved invoices
  • Progress billing tied to project milestones
  • Retention terms if applicable

Include a line for the GC or owner to sign and date. This turns your proposal into a simple contract once accepted. It also signals that you run a professional operation.

Stop Starting from Scratch on Every Bid

Most HVAC subs waste hours rebuilding proposals from scratch or copying and pasting from old jobs. That is time you could spend in the field or quoting more work.

A solid HVAC subcontractor proposal template standardizes your process. Every bid goes out looking sharp, covers all the right information, and protects your business legally.
