What Companies Has T3 Services Group Partner With?

T3 Services Group, formerly known as Radiant Holdings LLC, has rapidly built a multi-state residential home services platform through strategic acquisitions since 2020. Backed by The Riverside Company, T3 has grown from a single Austin plumbing and HVAC provider to a family of brands spanning Texas, Colorado, Washington, Idaho, and New Mexico, delivering comprehensive HVAC, plumbing, and electrical services across the United States.

T3 Services Group: Platform Overview

Founded in 2020 and headquartered in Austin, Texas, T3 Services Group operates under the tagline "Transforming the Trades." The company provides world-class resources and support to residential HVAC, plumbing, and electrical companies, offering shared services in marketing, recruiting, operations, finance, and business intelligence.

The Riverside Company, a global private equity firm focused on the smaller end of the middle market, invested in Radiant Plumbing and Air Conditioning in November 2020 as the platform company. The platform was subsequently rebranded to T3 Services Group to reflect its expanded geographic footprint and multi-brand strategy.

Similar to how platforms like Vertex Service Partners, Apex Service Partners, and Redwood Services have consolidated the home services market, T3 focuses on building a people-first culture while providing essential home services.

The Platform Company: Radiant Plumbing & Air Conditioning (November 2020)

Location: Austin, Texas
Founded: 1999
Founders: Brad and Sarah Casebier
Services: Maintenance plumbing, sewer, and HVAC services

The Riverside Company's investment in Radiant Plumbing and Air Conditioning marked the beginning of what would become T3 Services Group. Since 1999, Radiant had established itself as Austin's leading plumbing and HVAC provider, serving nearly 12,000 residential customers annually.

Radiant's employee-centric culture and five-star homeowner service experience had earned multiple recognitions, including:

• Multi-year winner of Austin Chronicle's "Best of Austin" for both plumbing and HVAC
• Austin Business Journal's "Best Places to Work"
• Austin American-Statesman's "Best of the Best" for 2020

According to Riverside Senior Partner Meranee Phing at the time of acquisition, "We're thrilled to partner with Brad and Sarah to enhance the growth efforts of an already thriving organization. We plan to assist with organic growth in Austin as well as inorganic growth in plumbing and HVAC services in Texas and beyond."

Jones Day represented The Riverside Company in the Radiant acquisition, which served as the foundation for the platform's expansion strategy.

First Add-On: Schmidt Mechanical Group (July 2021)

Location: San Antonio, Texas
Founded: Over 30 years of operation
Founders: Keith and Heather Schmidt
Services: HVAC installation, repair, and maintenance
Current Brand: Radiant Plumbing & Air Conditioning - San Antonio

Schmidt Mechanical Group represented T3's first add-on acquisition and geographic expansion beyond Austin. Founded by Keith Schmidt, a native San Antonian and graduate of Alamo Heights High School and Southwest Texas State University, the company had built a reputation for consistency, honesty, professionalism, and excellent service throughout the San Antonio market.

The acquisition allowed T3 to establish a presence in San Antonio while maintaining Schmidt's local brand recognition. The company now operates as Radiant Plumbing & Air Conditioning - San Antonio, combining Schmidt's decades of local expertise with Radiant's proven operational model. General Manager Anthony Price now leads the San Antonio operation, serving areas including San Antonio, Alamo Heights, Terrell Hills, and the Texas Hill Country region.

Second Add-On: Done Service Group (October 2021)

Location: Denver, Colorado
Founded: 1999
Founders: Jeromy and Lucas Metz
Services: Residential plumbing, HVAC installation and repair, excavation and sewer line services
General Manager: Kathy Armstrong

Done Service Group marked T3's expansion beyond Texas into the Denver metropolitan area. The company completed more than 15,000 jobs in the twelve months preceding the acquisition, with the majority of sales generated from repeat customers and membership program participants.

"Done is a natural fit for the Radiant platform, and we look forward to working with their team," said Riverside Senior Partner Meranee Phing. "Done is a top-tier brand that provides essential maintenance-focused plumbing and HVAC services, and its high repeat customer rate and strong brand awareness reflect Done's loyal customer base and commitment to service."

In 2022, T3 facilitated an internal merger between Done and APower Electric (acquired October 2022), one of Done's existing electrical subcontractors, to expand the company's service offering to include comprehensive electrical services in the Denver market.

Third Add-On: Mainstream Electric, Heating, Cooling & Plumbing (January 2022)

Location: Spokane, Washington and Coeur d'Alene, Idaho
Founded: 2000
Founders: Todd and Elaine Damschen
Services: Electrical, plumbing, heating, and air conditioning
General Manager: Brahn Shinkle

Mainstream Electric represented a significant strategic expansion for T3, extending the platform's reach into the Pacific Northwest. With over two decades serving the Spokane, Washington and Coeur d'Alene, Idaho regions, Mainstream had built exceptional relationships with homeowners through its commitment to providing an exceptional experience from the first call to service completion.

"We are thrilled to work with Todd & Elaine Damschen, Mainstream's management team and its expert technicians," said Riverside Senior Partner Meranee Phing at the time of acquisition. This marked T3's third add-on acquisition following Schmidt Mechanical and Done Service Group.

Fourth Add-On: B. Carlson Heating, Air Conditioning & Plumbing (August 2022)

Location: Albuquerque, New Mexico
Founded: 1971
Services: Plumbing, heating, and air conditioning
General Manager: Gary Gallegos

Founded in 1971, B. Carlson is one of Albuquerque's most tenured and trusted providers of plumbing, heating, and air conditioning services. The acquisition extended T3's geographic footprint into New Mexico, adding over 50 years of operational history and deep community roots.

B. Carlson's longevity in the Albuquerque market—operating for over five decades—demonstrates the type of established, community-focused companies T3 seeks to partner with. Under the leadership of General Manager Gary Gallegos, B. Carlson continues serving residential customers throughout the Albuquerque metropolitan area.

Fifth Add-On: APower Electric (October 2022)

Location: Denver, Colorado
Acquisition Context: Merged with Done Service Group
Services: Electrical services

APower Electric was acquired in October 2022 and merged with Done Service Group to create a comprehensive home services provider in the Denver market. This internal consolidation strategy allowed T3 to offer customers a complete suite of plumbing, HVAC, and electrical services under a single trusted brand.

The merger exemplifies T3's approach to building full-service capabilities in each market rather than maintaining separate specialized brands. The integration expanded Done's service offering and created additional career opportunities for electrical technicians within the T3 family.

Sixth Add-On: Schneider's Refrigeration & Appliance Service (November 2022)

Location: Details not publicly disclosed
Acquisition Date: November 2022
Services: Refrigeration and appliance services

According to The Riverside Company's portfolio information, Schneider's Refrigeration & Appliance Service was acquired in November 2022. This acquisition potentially broadened T3's service capabilities beyond traditional HVAC and plumbing into appliance repair and commercial refrigeration services, though specific operational details remain limited.

Seventh Add-On: Bulldog Rooter (January 2023)

Location: Spokane, Washington and Coeur d'Alene, Idaho
Founded: 2007
Services: Plumbing, drains, and trenchless pipe lining
General Manager: Chris Allen

Bulldog Rooter was acquired in January 2023, representing T3's second brand in the Spokane/Coeur d'Alene market alongside Mainstream Electric. The family-owned and operated plumbing specialist complements Mainstream's electrical and HVAC focus, creating comprehensive home services coverage in the Pacific Northwest.

Bulldog Rooter specializes in sewer line repair, water filtration, drain cleaning, leaking pipes, plumbing fixture repair, and water heater repair and replacement. The company operates 24/7 with no extra fees for emergency services, earning recognition as Spokane's premier plumbing service provider.

The acquisition announcement by Joe Finney, CEO of T3 Services Group (formerly Radiant Holdings LLC), emphasized that the company was "proud to announce the acquisition of Bulldog Rooter and NuFlow Trenchless Spokane," highlighting T3's continued mission of "delivering best-in-class services in plumbing, drains, HVAC, and electrical to the communities we serve, but also, fostering growth-oriented workplaces."

Additional Brand: 72 Degrees Air Conditioning, Heating, and Plumbing

Location: Fredericksburg, Texas (Texas Hill Country)
Founded: 1986
Service Areas: Kerrville, Fredericksburg, Mason, and Boerne
General Manager: Anthony Price

While the exact acquisition date is not publicly disclosed, 72 Degrees Air Conditioning, Heating, and Plumbing appears on T3's current partner companies list. The company provides homeowners with worry-free comfort throughout the year in the Texas Hill Country region, serving communities including Kerrville, Fredericksburg, Mason, and Boerne.

With nearly 40 years of operation since its founding in 1986, 72 Degrees brings significant operational history and deep roots in the Hill Country market. The brand continues operating under its original name, consistent with T3's approach of maintaining local brand equity.

T3 Services Group's Partnership / Acquisition Strategy and Geographic Footprint

As of 2025, T3 Services Group operates seven distinct brands across five states:

Texas (3 brands):

• Radiant Plumbing & Air Conditioning - Austin
• Radiant Plumbing & Air Conditioning - San Antonio (formerly Schmidt Mechanical)
• 72 Degrees Air Conditioning, Heating, and Plumbing - Fredericksburg/Hill Country

Colorado (1 brand):

• Done Plumbing, Heating, Cooling & Electric - Denver

Washington/Idaho (2 brands):

• Mainstream Electric, Plumbing, Heating & Cooling - Spokane/Coeur d'Alene
• Bulldog Rooter - Spokane/Coeur d'Alene

New Mexico (1 brand):

• B. Carlson Heating, Air Conditioning & Plumbing - Albuquerque

This geographic distribution demonstrates T3's strategic approach of establishing strong market positions in mid-sized metropolitan areas rather than spreading thinly across numerous small markets. Similar to strategies employed by entrepreneurs like Tommy Mello and the Hoffman Brothers, T3 focuses on building density in selected regions.

The Riverside Company's Role and Resources

The Riverside Company, jointly headquartered in Cleveland, invests in growing businesses valued at up to $400 million in the small and medium-sized business segments. For more than a decade, Riverside has invested in branded consumer companies with a special focus on home services.

Riverside's approach involves working closely with management to foster growth through organic initiatives and strategic acquisitions, paired with consumer and home services expertise and global resources.

What Makes T3 Different: The "Culture Crew" Approach

T3 Services Group distinguishes itself through a unique cultural initiative called the "Culture Crew." This cross-brand team comprises passionate, diverse individuals from T3's home services companies who meet monthly to brainstorm and champion culture-forward initiatives.

According to T3, "The Culture Crew is united by a shared goal—to create workplaces where people feel valued, motivated, and connected. Friendly, driven, and team-oriented, the Culture Crew isn't just about culture—it is the culture."

This emphasis on company culture aligns with successful operators in the home services space, including John Wilson of Wilson Companies and Jack Carr of Jackquisitions, who prioritize employee development and satisfaction.

Shared Services and Support Infrastructure

T3 provides comprehensive shared services to its partner brands, including:

• Marketing & Lead Generation: Traditional and digital marketing expertise with access to best-in-class agency partners to increase lead volume and quality
• Recruiting & HR: Talent acquisition teams that help bring top talent into partner companies, addressing the chronic labor shortage in skilled trades
• Finance & Accounting: Expert accounting teams providing better data faster, allowing local operators to focus on service delivery
• Business Intelligence: Systems and data science teams enabling faster and better decision-making with cutting-edge technology
• Training & Development: Professional development programs across sales, production, and leadership to upskevel team members
• Purchasing Power: Bulk purchasing programs that reduce costs for equipment, vehicles, and supplies

This comprehensive support model allows local businesses to maintain their operational autonomy while benefiting from enterprise-level resources, similar to approaches used by Wrench Group's portfolio companies.

Joe Finney - CEO
A results-driven executive with over 35 years of experience successfully growing businesses. Previously held leadership roles including positions at Baldwin Risk Partners.

Chris Anderson - Chief Operating Officer
Previously served as Investor and Senior Vice President of Business Development at GO Car Wash, with prior roles as COO at SafeBasements and President & CEO for both Marmon Group and Mark VII Equipment.

Sales Performance Enhancement

For home services companies looking to maximize their performance after joining a platform like T3, understanding modern sales techniques is essential. Technologies like AI-powered in-home sales coaching and advanced HVAC in-home sales coaching strategies in 2025 are transforming how technicians and comfort advisors close deals.

Industry Context: The Home Services Consolidation Wave

T3's growth trajectory reflects broader consolidation trends in the home services industry. Private equity firms and strategic platforms are aggressively acquiring residential service companies for several reasons:

• Fragmented Market: Thousands of independent operators create abundant acquisition targets
• Recurring Revenue: Essential home services generate predictable, recession-resistant revenue
• Skilled Labor Shortage: Larger platforms can better recruit and retain qualified technicians
• Technology Investment: Platforms can leverage technology investments across multiple locations
• Brand Recognition: Customers increasingly prefer established, professional service providers

This consolidation pattern is evident across multiple segments, from plumbing and HVAC platforms like T3 to roofing specialists like Vertex Service Partners, and broader home services consolidators built by entrepreneurs such as Chris Hoffmann and A1 Garage Door's ownership.

What This Means for Home Services Business Owners

For HVAC, plumbing, and electrical business owners considering a partnership or exit, T3 Services Group represents a platform specifically focused on their trades with:

Local Brand Preservation: Partner companies continue operating under their existing brands (or transition to Radiant in some cases) Operational Autonomy: Local management teams retain day-to-day operational control Resource Access: Immediate access to marketing, recruiting, finance, and operational support Growth Opportunities: Both organic growth support and potential expansion through add-on acquisitions Employee Development: Training programs and career advancement opportunities for technicians and staff

T3 actively seeks partnerships with established home services companies that share their values around customer service and employee experience. Interested business owners can contact the company through their website to explore partnership opportunities.

The Road Ahead for T3 Services Group

With a strong foundation of seven brands across five states and backing from The Riverside Company's extensive resources, T3 Services Group is positioned for continued expansion in the residential home services space. The platform's focus on culture, operational excellence, and employee development differentiates it in an increasingly competitive consolidation market.

As the home services industry continues consolidating—whether through PE-backed platforms like T3, roofing specialists like Vertex, or entrepreneur-led groups—established regional providers have more partnership options than ever before. Understanding the different platform approaches and finding the right cultural and strategic fit has become essential knowledge for business owners planning their next chapter.
