Harvest Partners Completes Acquisition of Integra Testing Services

On July 1, 2026, Harvest Partners, LP, a prominent private equity firm, announced the successful acquisition of Integra Testing Services, a leading provider in commercial HVAC (Heating, Ventilation, and Air Conditioning) testing and controlled environment services. This strategic move aims to bolster Harvest's capabilities in a sector characterized by high criticality and demand for reliability, particularly in fields like life sciences, healthcare, and education.

Integra, under the continuing leadership of CEO Dominic Mazzolini, was previously owned by Keystone Capital Management, LP. The acquisition terms have not been disclosed, but the partnership promises significant growth potential for both companies. Integra’s extensive suite of services includes testing and certification of cleanrooms, fume hoods, and ensuring compliance across multiple complex facilities.

Mazzolini expressed optimism about the future, stating, “Harvest's growth orientation and experience will be invaluable as we strive to offer superior quality services to our clients.” His leadership team remains committed to delivering high-caliber results to existing customers while exploring new markets.

Harvest Partners, known for its targeted investments in service-oriented companies, sees this acquisition as fitting well within its broader strategy. According to Stephen Fessler, a partner at Harvest, “Integra has established itself as a leading national platform for TAB (Testing, Adjusting, Balancing) and CE (Controlled Environment) services, making it well-positioned to expand its service offerings.” He highlighted the company's focus on the complexities involved in operating critical facilities and ensuring minimal downtime.

The demand for HVAC testing and controlled environment certifications is particularly acute in industries where operational failure can lead to severe repercussions. This includes sectors like pharmaceutical manufacturing, healthcare settings, educational institutions, and government facilities. The integration of Integra's services to provide a complete solution is seen as particularly attractive for organizations looking to minimize risks associated with operational failures.

Harvest Partners is positioned to leverage its extensive resources to enhance Integra's operational capabilities, with the potential for organic growth and strategic acquisitions. Shane McHugh, a principal at Harvest, noted that Integra aligns with several of Harvest's long-standing investment themes, including specialty testing and infrastructure services.

Founded in 1981, Harvest Partners boasts a diverse portfolio and has managed over $20 billion in assets as of March 31, 2026. Their philosophy emphasizes collaboration with management teams to drive growth through both organic methods and acquisitions, strengthening the businesses in which they invest.

Integra Testing Services, with its substantial operational footprint across the U.S., Mexico, and Guam, operates with over 600 professionals across 30 locations. Their expertise in unbiased testing is crucial for building owners and design professionals aiming for optimal operational conditions in their facilities.

As the partnership between Harvest and Integra evolves, both companies are geared towards enhancing their market presence while ensuring high levels of service continuity and operational excellence for their customers. The partnership is poised to contribute meaningfully to the standards of HVAC testing and controlled environments, especially where safety and compliance are paramount.
