Why an engineer started a marketing agency

My path to marketing started over 20 years ago, when I was designing commercial HVAC equipment and referred to as "The Girl" by my colleagues (hence you'll see The HVAC Girl).

My days were spent on specifications, performance data, and the design choices that decided whether a unit works in the field. Along the way, I noticed something: the products we engineered were excellent, but the brochures and websites selling them rarely did them justice. I wanted to create marketing for engineered products that was as good as the products themselves.

That idea became THG (The HVAC Girl) Marketing. Here's why I believe an engineer belongs on the marketing side of the table for MEP companies.

The MEP & Marketing translation gap

Engineered companies are built by people who think in specifications, tolerances, and performance data. That precision is what makes their products work. It's also what makes their marketing hard to read.

Browse the website of almost any MEP manufacturer, rep firm, or commercial HVAC contractors or engineers and you'll see the pattern: feature lists, part numbers, and technical language written by experts for other experts. Buyers are asking different questions. Will this keep my project on schedule? Will it pass inspection? Will it save my crew time on the jobsite? What happens if something goes wrong?

The answers are usually in there somewhere, they they just aren't framed around the buyer's problems. And because most buyers now research suppliers online before they ever pick up the phone, that framing often decides who gets the call. Closing that gap takes someone who can read a spec sheet, understand what it means in the field, and turn it into a message a buyer cares about. An engineer with real marketing experience can speak both languages without losing anything in translation.

The learning curve problem

Many technical companies hire a general marketing agency first. On paper, it's a reasonable choice. In practice, it often stalls.

Before a non-technical team can write a credible word about a VRF system, a fire suppression product, or a BIM coordination platform, someone has to teach them. That someone is usually your engineer, product manager, or sales lead, the same people who are already stretched thin. The result is hours of onboarding calls, line-by-line draft reviews, and corrections to basic errors.

Even then, there's no guarantee it sticks. Marketing professionals are skilled at what they do, but they aren't engineers. They may learn the vocabulary without grasping how a product performs, where it fits in a system, or why one design choice matters more than another. Your buyers notice. Engineers, contractors, and facility managers can tell within a sentence whether the writer understands the subject, and content that doesn't hold up costs you credibility.

Why B2C playbooks fail in MEP

The second problem is subtler. Many agencies cut their teeth on consumer brands, and their instincts follow them. They reach for catchy slogans, emotional hooks, trend-driven social posts, and campaigns built for impulse decisions.

That approach doesn't work in the MEP world. A mechanical contractor choosing equipment or an engineer specifying a product isn't scrolling for inspiration. Selling commercial equipment and engineering services is never a one-call close. Purchases involve long sales cycles, multiple decision-makers, and real liability if something fails. Buyers want proof, such as performance data, code compliance, case studies, installation details, and evidence that a supplier will stand behind its product.

B2B marketing in this space is about building trust over time. It means content that helps engineers specify with confidence, gives contractors what they need to bid and install, and shows owners the long-term value. Clever doesn't close those deals. Credible does.

What an engineer-led agency does differently

I started THG Marketing because small and mid-size manufacturers, manufacturers' reps, and mechanical contractors deserve a marketing partner who already understands their world. With clients, we skip the crash course and get straight to the work. We sharpen- the message, identify- who really makes the buying decision, and answer- the questions those people ask. That shows up in LinkedIn content engineers take seriously, websites written for specifiers and decision-makers alike, email campaigns that stay with a lead through a long sales cycle, and collateral that holds up in a technical conversation.

The result is marketing that sounds like it came from inside the industry, because it did. Your experts spend less time explaining and more time doing what they do best, and your buyers get messaging they can trust.
