Sustainability with substance:KlimaShop! is joining the bluu unit.
Bluu unit is an alliance dedicated to natural refrigeration and air conditioning technology that supports ambitious climate goals. To achieve these goals, we need members who have firmly embedded sustainability into their daily business operations. KlimaShop! GmbH, based in Friedberg and the newest member of bluu unit, does not view sustainability as a passing trend, but has been consistently implementing it for years—long before climate protection became an industry-wide issue.
Sustainability That Can Be Measured
For over 15 years, KlimaShop! has adhered to a clear principle: every system installed is accompanied by concrete measures to reduce CO₂ emissions. In return, customers receive their own sustainability certificate that highlights this contribution and is actively promoted within many companies. In doing so, KlimaShop! has established a model that translates sustainability from theory into practice—in a transparent, scalable, and consistent manner.
Climate comfort and energy efficiency designed to last

KlimaShop! is run by second-generation managing directors Armin (left) and Peter Spengler (right) and employs around 30 people. The company has over 55 years of experience in the field of HVAC technology and has continued to evolve throughout this time.
Projects such as the Best Western Hotel München-Airport and the Sternodrom office complex in Augsburg demonstrate how modern HVAC systems and smart energy use can be combined to achieve long-term results. For this work, KlimaShop! was honored with the Panasonic PRO Award just last year and cited by the German Federal Environment Agency as a model example of outstanding, sustainable solutions. The combination of innovative craftsmanship, business continuity, a family-oriented corporate culture, and professional standards makes KlimaShop! a partner that is a perfect fit for bluu unit.
Technical expertise and personal dedication with proven results
KlimaShop! strengthens its network through technical expertise in energy-efficient HVAC systems, clearly structured processes, and high efficiency. In addition, the company stands out for its open, team-oriented approach, its many years of experience—particularly in the hospitality, office, and commercial real estate sectors—and its excellent customer loyalty, which extends far beyond service and maintenance. This combination not only creates added value for customers but also unlocks new potential for collaboration and knowledge transfer within the alliance.
Potential for both sides
“KlimaShop! stands for a strong corporate culture, values put into practice, and a high degree of responsibility toward both customers and its own employees. It is precisely companies like this that help our alliance grow,”
says Nicolo Freyberg, Managing Director and Co-CEO of bluu unit.
Peter Spengler, CEO of KlimaShop!, is also looking ahead with confidence:

“For us, joining bluu unit is an important step toward preparing our company for the next generation. We want to build a sustainable future for our life’s work while offering our employees stable prospects.”
Ensuring growth, shaping the future, offering opportunities
With the addition of KlimaShop!, bluu unit continues its strategy of strategically integrating companies that offer more than just technical expertise. A strong identity, clear values, and a consistent focus on the climate-friendly technologies of tomorrow are what bind this alliance together. It is driven by companies that don’t just articulate their values—they put them into practice, thereby demonstrating what the future of refrigeration, air conditioning, and ventilation technology can look like.
