How to prepare a commercial mechanical contractor for sale

What do buyers look for in a commercial mechanical contractor?#

Buyers of commercial mechanical contractors look first at the split between service and construction. Service agreements for preventive maintenance on rooftop units, chillers, boilers and air handlers renew and pull through repair work, while bid construction depends on winning the next job. Most buyers weight the service side heavily and price construction on its track record.

After the mix, they test whether the business runs without the owner: who sells service agreements, who runs the service board, who estimates and who manages projects. They also check bonding capacity, licenses, labor agreements and safety history, because each can limit what the company can bid after closing.

Checklist: service agreements#

Service agreements are the asset buyers diligence hardest, so each one needs a file that stands on its own. A buyer will sample agreements and compare the scope on paper with the visits your field service system says were completed.

Unsigned renewals are a common gap. If agreements have rolled forward for years on invoices alone, collect current signatures before a process starts, and confirm the scope still matches the equipment on site.

• 1A master list of agreements with customer, site, start date, renewal date, term and billing frequency.
• 2The signed agreement and current scope for each site, including the equipment list it covers.
• 3Escalation and renewal clauses, plus any assignment or change-of-control terms a buyer must review.
• 4PM visits scheduled versus completed by site, exported from ServiceTitan, BuildOps or whichever system runs the service board.
• 5Repair and replacement work generated from PM visits, linked back to the agreement that produced it.
• 6Cancellation history with reasons, including agreements lost at rebid.

Checklist: building automation system access#

Building automation access is a risk specific to mechanical contractors, because customers depend on the contractor to keep controls running. If programming files, graphics and passwords for customer systems sit on one technician's laptop, a buyer is acquiring a relationship that could walk out the door.

Checklist: WIP schedules and project history#

The WIP schedule is the core proof of project margins, and buyers will compare it month by month with the financial statements. A schedule that changes estimated margins late in a job, or that cannot be tied to the general ledger, tells a buyer to discount the construction side.

Keep the project history itself, not just the schedule. If you run Procore, its Procore Extracts desktop app can save an archive of a project's information, but Procore says it requires Admin-level permissions on each tool you extract from and should run on a computer that stays on and online. Schedule archive runs for closed projects before anyone's access changes.

Checklist: people, licenses, bonding and safety#

People and permits decide whether the company can keep working after the owner steps back. Buyers read these files alongside the financials, and gaps here often turn into earnouts or employment conditions rather than price cuts.

• 1Licenses: which individuals hold the mechanical, plumbing or refrigeration licenses the company relies on, and what happens if they leave.
• 2Key people: service manager, controls lead, senior project managers and estimators, with retention plans where appropriate.
• 3Labor agreements: union contracts and benefit fund obligations, or open-shop pay and benefit policies.
• 4Bonding: a letter from your surety and the history of bonded work.
• 5Safety: incident logs, training records and your experience modification history from your insurance carrier.
• 6Warranty: open warranty obligations on completed projects and how they are tracked.

Who owns the drawings in your project files?#

Drawings and specifications in a mechanical contractor's project files usually belong to the design team, not the contractor. Under the widely used AIA A201-2017 general conditions, the contractor and its subcontractors may use and reproduce the architect's instruments of service only to perform the work, and may not use them on other projects without specific written consent from the owner, the architect and the architect's consultants.

That matters twice in a sale. A buyer should not assume design documents in your archive are company property, and any later use of project records, including licensing operational data, has to separate your own records from documents you hold under someone else's terms. RFIs, daily logs, service reports, PM checklists, estimates and closeout notes are usually the contractor's own work, but your contracts decide, so review them with counsel.

Illustrative: a mechanical contractor with a strong service book#

Illustrative: a fictional commercial mechanical contractor does design-assist construction and runs a service department with PM agreements for office buildings, schools and light industrial sites. Service runs on a field service platform, accounting on a construction ERP, and controls programming files live on the laptops of two senior technicians.

Before engaging an advisor, the owner moves every controls backup and credential into a company vault, collects current signatures on agreements that had been renewing on invoice alone, and has the controller reconcile monthly WIP schedules back several years. The project archive for closed jobs is exported ahead of a planned software change.

When buyers arrive, the service book survives sampling and the WIP history explains the one difficult project. The conversation centers on growing the service department rather than on whether customers would follow the technicians.

How SourceX fits into a sale plan#

SourceX helps contractors license operational records, such as service tickets, PM checklists, equipment histories and project RFIs, to AI developers without selling them outright. The fit check uses metadata only, and nothing is shared until the company approves each step of the SourceX five-step transaction: Supply, Rights, Preparation, Approval and Delivery.

If a sale is planned, sequence matters. A license signed beforehand will be disclosed and read by the buyer's counsel, so terms such as exclusivity and delivery obligations should be clear. The SourceX Evidence Packet records provenance, licensing rights, permitted use, the privacy record and release authorization, which gives a buyer one clean document to review.
