What General Contractors Look For on an MEP Contractor Website

What an MEP contractor website should show general contractors and facility managers: systems, capacity, service area, certifications and checkable references.

Written by the Miriad team with AI assistance. Figures link to their sources; the example is illustrative. Updated 2026-10-21.

TL;DR: A general contractor or facility manager visits an MEP contractor website to answer one question: can this firm handle our job? Show the systems you install, the building types and size bands you work in, your service area, certifications, maintenance capability and a few checkable references. Write it for the person adding you to a bid list, not for homeowners, and keep every claim one you can prove.

A GC's project manager has a new bid package and a mechanical subcontractor list that is two names short. A colleague mentions your firm. Before sending an invitation, the project manager spends a few minutes on your website. The home page shows a smiling family next to a thermostat and the line "Your comfort is our priority". There is a phone number and a list of services that includes "AC repair" and "boiler service". Nothing says whether you have ever installed an air handling unit on a three-storey building. The project manager moves on. This article is part of our guide on how an MEP contractor can use AI to win more bids.

Who visits an MEP contractor website, and what do they decide there?

Three kinds of visitors decide something on an MEP contractor's website: general contractors deciding whether to invite you to bid, facility managers deciding whether to call you for maintenance or a replacement, and job candidates deciding whether to apply. Homeowners matter too if you do residential work, but they need a different page, not the same home page.

The GC and the facility manager are checking capacity and fit, quickly. They want to know your systems, your size range, where you work, whether you have done their building type, and whether you can staff the job. They are not looking to be persuaded. They are looking for a reason to add you to a list, or a reason not to.

Candidates are the third audience, and an important one given the hiring market. Among firms in AGC's 2025 survey of the $50.1 million to $500 million segment that tried to hire, 85% reported difficulty for plumbers and 89% for electricians, from small sub-samples (AGC, 2025). A careers page that shows real projects helps there too.

What should the home page answer in the first screen?

The first screen should say what you install, for which building types, and where. One sentence and a short list is enough: mechanical and plumbing contractor, commercial and public buildings, region served, with links to systems, references and maintenance. A GC should know within seconds whether to keep reading.

Good: "Mechanical and plumbing contractor for schools, care homes and offices in the north of the region. Heating, ventilation, heat pumps, controls and domestic water, design-and-build or to engineer's drawings." Weak: "Delivering excellence in building services since 1998."

Put a direct contact for estimating on the first screen, separate from the service line. A GC with a bid invitation does not want to go through the breakdown call queue.

Which pages does a GC or facility manager expect?

They expect a systems page, a references page, a page on how you work with GCs, a maintenance page if you offer service, a page on certifications and safety, and a contact page with an estimating email. Each page should hold facts that someone checking you can verify, not adjectives.

Page What it should show Who reads it
Systems Heating, cooling, ventilation, plumbing, controls, heat pumps; equipment types you install GC estimator, engineer
References Case studies by building type, with scope, systems and programme GC, facility manager
Working with GCs Bid process, submittals, programme coordination, typical package sizes GC project manager
Maintenance and service Service agreements, response arrangements, systems you maintain Facility manager
Certifications and safety Licences, refrigerant certification, insurance, safety record you can document GC compliance, owner
Service area Regions you cover for projects and for service Everyone
Careers Real projects, roles, how to apply Candidates
Contact Estimating email for bid invitations, service line, office address if staffed Everyone

References carry most of the weight. How to write them from closeout documents is in turning closed jobs into reference case studies.

How do you show capacity without exaggerating?

Show capacity with facts a GC can check: the building types and size bands you have completed, the number of crews or project managers you can field, the systems you self-perform and those you subcontract, and the regions you cover. Leave out claims you cannot back. A GC who finds one inflated claim discounts the whole site.

Be precise about certifications, because they are regulated. In the US, technicians who handle refrigerant need EPA certification, and some states and localities also require a licence (BLS, 2026). In the EU, refrigerant work must be done by certified personnel under the F-gas rules (IDM Energiesysteme, 2026). Say what your firm and your staff actually hold. "All our engineers are certified" is a claim a GC may test.

Self-perform versus subcontract is the other honest line that helps. If you subcontract insulation and controls, say so. A GC planning a programme would rather know now than discover a sub-subcontractor during submittals.

What about reviews and Google Business Profile for a commercial MEP firm?

Keep a correct Google Business Profile even if most of your work is commercial, because facility managers and GCs search for you by name and see it first. Follow Google's rules on addresses, service areas and business names. Collect reviews from every client the same way, and show them on your site if you do service work.

On Google Business Profile, a firm that serves customers at their sites should hide a home address, keep its service area within about two hours' drive of its base, and keep service keywords and locations out of the business name; PO boxes and unstaffed virtual offices are not accepted (Google Business Profile Help, accessed 2026).

For the service side of the business, reviews do real work. BrightLocal's 2025 survey of 1,026 US adults found that 74% of consumers use two or more review sites before deciding, while only 6% use ChatGPT or other AI tools to find reviews (BrightLocal, 2025). How reviews fit with residential and service leads is covered in HVAC contractor leads.

Example: rewriting a home page for GCs

Example (illustrative, not a real case): A 35-person mechanical contractor does mostly commercial work for three regional GCs, plus service agreements for a few dozen buildings. Its website was built years ago for residential customers. The owner gives an AI assistant the company's reference list, the systems they install, the capture sheets from recent handovers and the table above, and asks for a new home page draft and a systems page, using only those documents.

The draft first screen reads: "Mechanical contractor for schools, healthcare and offices across the region. Heating, ventilation, heat pumps and controls, from engineer's drawings or design-and-build. Bid invitations: estimating email." The systems page lists equipment types with a reference project next to each. The owner deletes a line the AI added about "24/7 emergency response", because the firm does not offer it outside its service agreements, and adds the name of the estimating contact.

The residential pages stay, moved under a "Homes" menu item, so a homeowner still finds them and a GC no longer lands on them.

How should AI help write the website?

Use AI to draft pages from your own documents: reference lists, capture sheets, certification records, the systems you install. Tell it to use only those sources and to mark gaps rather than fill them. Then check every claim against the documents. The value is in speed of drafting; the risk is a confident claim you cannot support.

Keep the content as plain text on the page, not inside images or PDFs, so that both search engines and AI assistants can read it. And never let AI write reviews or testimonials: the FTC's 2024 rule bans fake reviews and testimonials, including AI-generated ones (FTC, 2024).

FAQ

Should a commercial MEP contractor's website include prices?

Usually not for project work, because prices depend on the bid package and change with every job. What a GC needs is the size range and building types you handle, so they know whether to invite you. For service agreements, a clear description of what is included and how to request a quote is more useful than a public price list.

Do GCs really look at subcontractor websites?

Many check a website before adding a new subcontractor to a bid list, especially when the recommendation came from a colleague. They look for systems, building types, references and a contact for bid invitations. A site written only for homeowners can make a capable commercial firm look like a small residential outfit, so give GCs their own clearly labelled pages.

How many reference projects should be on an MEP contractor website?

Enough to cover each main building type and system you want to bid for, with a short case study for each. A few well-documented references with scope, systems and programme are more convincing than a long logo wall. Publish only with the client's permission, and keep contract values off the public site unless the client agrees.

Can AI write my MEP contractor website?

It can draft it well if you give it your own documents: reference lists, systems, certifications and closeout notes. It should not invent capabilities, response times or certifications, and it will try to fill gaps with generic claims unless told not to. Ask it to mark missing information, then check every statement before publishing.
