MAX Service Group, the residential home services platform that operates Williams Comfort Air and Mr. Plumber in central Indiana, Thomas & Galbraith Heating, Cooling, Plumbing & Electrical in southwestern Ohio, and Buckeye Heating, Cooling, Plumbing & Electrical in greater Columbus, announced expansion activity across its Midwest portfolio in April 2026, according to HVAC Insider.

MAX Service Group is not a name that dominates national HVAC consolidation coverage — but its geographic footprint across three major Midwest markets (Indianapolis, Cincinnati, and Columbus) makes it one of the most strategically positioned multi-state residential home services platforms in the central US. Operating established, well-known local brands in three adjacent major metros creates a platform with genuine synergies that single-market operators cannot replicate.

The Three-Market Strategy

MAX Service Group's portfolio architecture — three distinct brands in three adjacent major metro markets — reflects a specific approach to regional platform building:

• Williams Comfort Air (Indianapolis): One of central Indiana's most established HVAC and plumbing brands, with deep contractor relationships and consumer brand recognition across the Indianapolis metro

• Thomas & Galbraith (Cincinnati/Southwest Ohio): A well-recognised multi-trade home services brand in the Cincinnati-Dayton corridor, one of the densest residential markets in the Midwest

• Buckeye Heating, Cooling, Plumbing & Electrical (Columbus): Operating in the fastest-growing major Ohio metro, where population growth and new construction are generating above-average residential HVAC demand

The three markets collectively represent more than 4 million households in the Midwest's most economically stable, consistently performing residential markets. None of the three is a boom-and-bust market; all three have steady, durable residential HVAC demand that comes from population stability, aging housing stock, and predictable replacement cycles.

MAX Service Group's Midwest portfolio — Williams Comfort Air (Indianapolis), Thomas & Galbraith (Cincinnati), and Buckeye (Columbus) — creates a three-major-market residential HVAC and home services platform covering more than 4 million households across Ohio and Indiana's most economically stable metropolitan areas.

The Midwest Advantage for HVAC Platforms

The Midwest gets less attention in HVAC consolidation coverage than the Sunbelt — but it has specific structural advantages for residential home services platforms that are often underappreciated:

• Housing stock age: Midwest housing stock is older on average than Sunbelt markets. Older homes generate more repair and replacement demand per household than newer construction. A 1980s home in Cincinnati needs maintenance that a 2022 home in Phoenix does not.

• Year-round demand: Midwest climates generate both heating and cooling demand — creating more even revenue distribution across the calendar than purely cooling-dominated Sunbelt markets. A contractor serving Cincinnati serves heating in winter and cooling in summer with roughly equal intensity.

• Less PE competition: The Sunbelt markets most attractive to PE platforms are the ones where the most capital is concentrated. The Midwest has proportionally less PE presence, meaning established brands like Thomas & Galbraith and Williams Comfort Air face less direct PE platform competition than comparable businesses in Phoenix or Dallas.
