Harrell-Fish Acquires EcoFriendly Mechanical in Louisiana Expansion

Harrell-Fish Inc., a Houston-based mechanical contracting firm, acquired EcoFriendly Mechanical Services in Baton Rouge, Louisiana, the company announced Thursday. Financial terms weren't disclosed, but the deal marks Harrell-Fish's second Louisiana acquisition in 18 months and its fourth transaction since 2019 as the contractor pushes deeper into Gulf Coast markets.

EcoFriendly Mechanical, founded in 2002 by Steve Hebert, specializes in HVAC, refrigeration, and commercial kitchen equipment installation and maintenance across Baton Rouge and surrounding parishes. The company employs roughly 40 people and has built a client base spanning restaurants, healthcare facilities, and commercial real estate — sectors where Harrell-Fish sees sustained demand despite broader construction market volatility.

The acquisition extends Harrell-Fish's Louisiana footprint beyond its 2023 purchase of Accu-Temp Mechanical in Lafayette, part of a deliberate strategy to build out service density in markets where industrial, petrochemical, and institutional construction continues to drive mechanical contracting demand. Unlike some of its competitors consolidating around single metro areas, Harrell-Fish is betting on a multi-city presence across Texas and Louisiana.

"We've watched Louisiana's mechanical contracting market fragment over the past decade," said J. Doyle Jones, Harrell-Fish CEO, in the announcement. "EcoFriendly gives us the commercial service platform in Baton Rouge we've been looking for — recurring revenue, sticky customer relationships, and a team that actually shows up."

Baton Rouge isn't an obvious growth market on the surface. The metro area's population has been essentially flat since 2010, and its economy remains tethered to oil refining and petrochemicals — industries not exactly synonymous with stability. But that's precisely the point for contractors like Harrell-Fish.

Industrial maintenance spending in the Gulf Coast corridor has held remarkably steady even as new construction swings wildly with commodity prices. According to FMI Corporation, a construction industry consultancy, service and maintenance work now represents nearly 55% of total mechanical contracting revenue in Louisiana — up from 42% a decade ago. That shift makes companies like EcoFriendly, with their maintenance contracts and service call volume, more valuable than pure project-based installers.

Harrell-Fish also gets access to EcoFriendly's healthcare and food service verticals, two areas where the Houston firm has been underweight. Baton Rouge is home to multiple hospital systems and a sprawling restaurant sector that supports LSU's 35,000-student campus — both segments that require 24/7 HVAC and refrigeration uptime and don't blink at paying for it.

Still, the timing raises questions. Mechanical contractors across the Southeast are bracing for a slowdown in commercial construction starts as interest rates remain elevated and office projects stall. Harrell-Fish is choosing to expand through acquisition precisely when organic growth is getting harder to come by.

This isn't Harrell-Fish's first rodeo. The company, founded in 1980, has grown from a Houston industrial contractor into a regional platform through a mix of acquisitions and organic expansion. Its M&A activity accelerated sharply after 2019, when it brought on growth equity backing from an undisclosed investor (the company hasn't publicly named its financial sponsor, if one exists beyond family office capital).

The pattern is consistent: Harrell-Fish targets founder-owned mechanical contractors with 20–50 employees, strong service books, and geographic proximity to its existing operations. EcoFriendly fits the mold perfectly — a second-generation business where the founder is approaching retirement age and the next generation isn't interested in running the shop.

Post-acquisition, Harrell-Fish typically keeps local management in place, rebrands the company under its own name within 12–18 months, and cross-sells services between locations. Accu-Temp Mechanical in Lafayette, acquired in mid-2023, still operates under its original brand but now shares back-office functions, purchasing power, and bonding capacity with the Houston parent.

The Louisiana acquisitions suggest Harrell-Fish sees the state as a long-term platform for growth, not just opportunistic tuck-ins. Baton Rouge and Lafayette are only 50 miles apart, which creates potential for route density in service operations and shared staffing for larger projects.

EcoFriendly's sale is part of a larger demographic wave washing through the skilled trades. According to Associated Builders and Contractors, more than 40% of mechanical contracting firms in the U.S. are owned by individuals over the age of 60, and fewer than 30% have documented succession plans. That's creating a steady supply of acquisition targets for consolidators like Harrell-Fish, but it's also hollowing out the independent contractor market in some regions.

Revenue figures weren't disclosed, but based on employee count and typical per-capita productivity in mechanical contracting, EcoFriendly likely generates somewhere between $8 million and $12 million in annual sales. That's not transformational for Harrell-Fish, which operates at a significantly larger scale across its Houston and Louisiana operations.

The real value is in the service contracts. Commercial HVAC and refrigeration maintenance agreements are annuity-like revenue streams that smooth out the lumpiness of project work. EcoFriendly's customer base — hospitals, restaurants, cold storage facilities — can't tolerate downtime, which translates into high contract renewal rates and pricing power that commodity installation work doesn't offer.

Harrell-Fish also inherits EcoFriendly's relationships with equipment manufacturers. Commercial kitchen and refrigeration work requires specialized training and certifications from brands like Traulsen, Hoshizaki, and True Manufacturing. Those relationships don't transfer easily, and acquiring them wholesale through M&A is often faster than building them organically.

There's also the labor angle. Skilled HVAC technicians and refrigeration mechanics are scarce across the Gulf Coast, and poaching them is expensive. Acquiring a team of 40 that's already trained, licensed, and embedded in the local market solves a problem that can't be fixed by throwing money at job boards.

But integration isn't automatic. Mechanical contractors who've been independent for decades don't always adapt smoothly to corporate ownership, even when the acquirer promises operational autonomy. Harrell-Fish will need to retain EcoFriendly's key technicians and project managers, or the acquisition becomes a customer list with an expiration date.

EcoFriendly's commercial kitchen focus is worth lingering on. It's a fragmented, high-touch segment that larger mechanical contractors often ignore because project sizes are small and customer demands are unpredictable. But it's also recession-resistant — restaurants and institutional kitchens keep cooking regardless of economic cycles — and margins can be strong when the contractor knows the equipment cold.

Baton Rouge's food service sector is anchored by LSU, which operates multiple dining halls and campus eateries, plus a deep bench of independent restaurants and regional chains. That creates consistent demand for equipment installation, maintenance, and emergency repair work — the kind of high-margin service calls that make contractors smile.

Harrell-Fish isn't alone in pursuing a buy-and-build strategy in mechanical contracting. The sector has seen a wave of private equity-backed consolidation over the past five years, driven by the same trends: aging ownership, recurring service revenue, and fragmentation that makes bolt-on acquisitions relatively easy to execute.

Comfort Systems USA, a publicly traded mechanical contractor with a national footprint, has been particularly active in Texas and Louisiana. The company completed 15 acquisitions in 2023 alone, targeting firms with $5 million to $50 million in revenue. Its strategy mirrors Harrell-Fish's but at a much larger scale — and with access to cheaper capital through its public markets currency.

Private equity shops have also entered the fray. Firms like AEA Investors, MPE Partners, and Sun Capital have all backed mechanical contracting platforms in recent years, viewing the sector as a classic fragmented services roll-up opportunity with stable cash flows and limited technology disruption risk.

The question for independent operators like Harrell-Fish is whether they can compete with those deeper-pocketed acquirers without giving up equity to institutional capital. So far, the company seems to be threading that needle — growing through disciplined acquisitions without signaling any need for outside capital beyond what it can generate from operations or regional banks.

The broader Gulf Coast construction market is sending mixed signals. Industrial project activity — refineries, chemical plants, LNG terminals — remains robust, driven by energy export demand and reshoring trends in petrochemicals. Louisiana's industrial construction spending hit $8.2 billion in 2024, according to state economic development data, with another $12 billion in projects announced or under development.

But commercial construction is wobbling. Office project starts in Baton Rouge and New Orleans fell 23% year-over-year in 2024, and retail development has stalled as landlords digest elevated vacancy rates and cautious tenant demand. Healthcare and institutional construction — schools, hospitals, municipal facilities — has held up better, but permitting timelines have stretched and budgets are tighter.

For a service-heavy contractor like Harrell-Fish, these trends are manageable. New construction slowdowns hurt project-based installers more than maintenance and service providers. EcoFriendly's recurring revenue base should insulate the combined company from the worst of any commercial real estate downturn.

Still, if Louisiana's economy softens — oil prices are down 15% from their 2024 peak, and refining margins are under pressure — even service work can thin out as customers defer discretionary maintenance and stretch replacement cycles.

The EcoFriendly acquisition won't be Harrell-Fish's last. The company's M&A cadence — one deal every 12 to 18 months since 2019 — suggests another transaction is likely by late 2025 or early 2026. The question is where.

Logical targets include additional Louisiana markets (New Orleans, Lake Charles, Shreveport) or a deeper push into East Texas beyond Houston. The company could also expand vertically, adding plumbing, electrical, or controls capabilities to create a more comprehensive mechanical/electrical/plumbing (MEP) offering.

There's also the capital structure question. At some point, Harrell-Fish will likely need to bring in a financial partner if it wants to accelerate acquisitions or compete for larger targets against better-capitalized competitors. Whether that means private equity, a strategic buyer, or a public markets path remains unclear — the company hasn't signaled its intentions publicly.

For now, the focus will be on integrating EcoFriendly without losing the service quality and customer relationships that made it attractive in the first place. That's harder than it sounds in an industry where technicians are loyal to people, not brands, and customers care more about response time than corporate structure.
