Rocket Group, the Huntington Beach, California-based home services network and consulting company, acquired ProThermal Heating & Cooling — a well-established HVAC service provider based in Tulsa, Oklahoma. The acquisition is Rocket Group's second Oklahoma partnership in two months, demonstrating a systematic approach to the state's residential HVAC market. ProThermal brings 90 vehicles, 130 technicians and staff, and a customer base of nearly 255,000 to the Rocket Group network.

ProThermal co-founder Paul Berry expressed the alignment that drove the deal: 'This partnership sets us apart in the industry, ensuring our continued growth and success.' Rocket Group's model — maintaining local brand identity while providing national network resources and consulting support — appears to have been the deciding factor for ProThermal's leadership over alternative exit options.

ProThermal's Scale in the Tulsa Market

A customer base of 255,000 in the Tulsa metropolitan area — which has a population of approximately 1 million people — represents extraordinary market penetration. If we assume approximately 400,000 households in the greater Tulsa area, a 255,000 customer base suggests ProThermal has relationships with more than 60 percent of Tulsa households. That level of market penetration is the product of decades of service quality, consistent branding, and community presence that cannot be replicated quickly.

The 90-vehicle fleet and 130-person team confirm that ProThermal is a substantial operational business — not a small contractor but a significant regional HVAC enterprise that has scaled well beyond the typical owner-operated model. For Rocket Group, the ProThermal acquisition delivers immediate operational scale in a new market rather than the gradual build-out that organic expansion would require.

Rocket Group acquired ProThermal Heating & Cooling of Tulsa, Oklahoma — its second Oklahoma partnership in two months — adding 90 vehicles, 130 technicians and staff, and a customer base of nearly 255,000 to the Rocket Group national home services network.

Rocket Group's National Build-Out Strategy

Rocket Group is now operating across eight states with more than twelve partner companies, following the True Blue Mechanical (Delaware) and ProThermal (Oklahoma) additions in the most recent disclosed period. The pace of growth reflects a platform that has refined its partnership model and is executing it systematically across new geographies.

The Rocket Group approach differs from both traditional PE acquisition and the franchise model:

• It is not a franchise: Rocket Group does not charge franchise fees or impose franchise royalties. Partner companies retain their local brand identity and customer relationships.

• It is not a pure acquisition: While Rocket Group takes an ownership stake, the language consistently emphasises 'partnership' and 'investment' rather than acquisition — and the preservation of local leadership in partner companies is a consistent feature.

• It is a consulting and network model: Rocket Group provides business development, operational consulting, technology, and national marketing resources to partner companies rather than imposing a uniform operating system.

For HVAC business owners in mid-sized markets who want scale advantages without selling outright to PE, the Rocket Group model is worth understanding as a distinct alternative in the consolidating market.
