Barstow/Santa Clarita based home services company brings 30-plus years of trusted HVAC and plumbing expertise to growing national portfolio

SAN BERNARDINO, Calif. (June 24, 2026) – Rocket Group, a leading home services network and consulting company, added Clemmer Services (Clemmer) to its growing portfolio, bringing the trusted Barstow and Santa Clarita-based HVAC, heating, and plumbing company into its expanding national network. The partnership marks Rocket Group’s 14th brand as the company continues to expand its presence in key residential markets across the country.

Clemmer has built a reputation for honest, straightforward service throughout San Bernardino County and the surrounding Inland Empire for more than three decades, expanding its operations into the Santa Clarita Valley and Los Angeles County four years ago. The company’s bilingual technicians, transparent pricing, and 4.9-star Google rating align with Rocket Group’s mission to partner with established, community-trusted brands that deliver measurable results for homeowners.

“From day one, Clemmer Services was built on straightforward pricing and honest work, and our customers have rewarded us with their loyalty for three decades,” said Dave Barnard, Owner and Operator, Clemmer Services. “We are proud of what we have built here, and now we are ready to take it to the next level.”

The company offers a comprehensive range of residential and light commercial services, including air conditioning installation and repair, furnace and heating services, heat pump solutions, plumbing, sewer line repair, tankless water heaters, and indoor air quality systems. The company holds Trane Comfort Specialist certification and is an authorized Rinnai dealer, with NATE-certified technicians serving homeowners across Barstow, Apple Valley, Hesperia, Victorville, Santa Clarita, and beyond.

Through the Rocket Group partnership, Clemmer Services gains access to proven growth systems, enhanced sales training, strategic marketing support, and operational infrastructure that have driven significant revenue increases across the company’s other brands. The partnership extends Rocket Group’s footprint into Southern California’s high desert and Santa Clarita Valley, regions experiencing consistent residential growth and strong demand for home services.

“Southern California is a market we know well, and adding Clemmer Services to our portfolio was a natural next step. They have built something worth building on,” said Victor Rancour, CEO, Rocket Group Holdings. “Our job now is to give them the tools and support to grow faster and stronger than they ever could on their own.”

The addition of Clemmer Services becomes the 14th brand in the Rocket Group portfolio and the latest example of the company’s strategy of identifying high-performing regional operators and accelerating their growth. The Barstow and Santa Clarita markets, with their year-round demand for heating, cooling, and plumbing services, represent a strong opportunity for the kind of rapid, sustainable expansion Rocket Group has delivered across its other brands.
