Air has always played a major role

LSA Luft-Systeme Althuber GmbH is a family and master craftsman business from the beautiful area called "Mühlviertel" in Upper Austria. The connection to our immediate surroundings, as well as international projects around the globe are equally important to us. We are open-minded, tolerant and definitely do not see the earth in the shape of a disk. Our world is made up of air and love, clouds and the forces of aerodynamics, which we need as important ingredients for the secret of much better air. The passion for fresh air, the environment and well-being are the components of our mission, because everyone has the right to a healthy living space and the most important live-giving goods of all: AIR. Our story begins with Grandpa Fritz, who passed these core values on to his son and thus to this company, and which are still the core principles of "LSA" today.

We are not specialists. We are EXPERTS.


Over the last few decades, we have been able to plan, execute and complete thousands of projects, attend openings and watch a small idea grow into a great, well-known company. This is the motivation and incentive why we have not only been doing our job well for more than 20 years, but also doing it with pleasure.

Vincent van Gogh once said "What is done with love is done well." We follow this wisdom with passion and to support our clients and help them succeed with honest and fair expertise. We support and love nothing more than seeing a great result when we visit our customers, celebrate our company parties with them or come over as a family for a Friday lunch. LSA Luft-Systeme Althuber GmbH, including the great LSA team, believes in "taking and giving back even more". That is why we are proud of our work. We are proud that projects and business relationships, honest partnerships and even friendships have developed. We are grateful for the many encounters, the mutual appreciation, the positive feedback and numerous recommendations. This inspires us in our daily work and the praise from our customers is our greatest affirmation.


Our ideology is based on firm principles: Appreciation, trust, fairness and honesty.

Without these four basic requirements for our partnerships and relationships with our customers, suppliers and employees, we would not have been THE company for ventilation and air conditioning systems for over 20 years.


In addition to individual planning, a fair cost calculation plays a major role in pre-production. We always take time for you and create your personal air solution for all individual living spaces so that the implementation can take place without any problems.


Our team are not only experts in the installation of air conditioning and ventilation systems, but also always have their heads in the clouds when it comes to installing your ventilation system, even at dizzying heights. The team is always up to date with the latest knowledge and boasts decades of experience.


Once your new ventilation system has been installed and commissioned, it is very important to have it serviced and maintained regularly (at least once a year). This must be carried out by an authorized specialist. Regular maintenance of your system protects your appliance, your staff, your customers, the environment and your wallet. We are there for you in good times and bad. We see problems as a challenge and we always find a solution.


Have you ever packed a ventilation system including accessories and components in a shopping bag? You can with us. In addition to ventilation systems, we also offer a wide range of air conditioning systems and air handling units as well as various household goods that will bring a breath of fresh air into your home.


When it comes to sustainability, we are careful to calculate our solutions and implementation in such a way that you not only save electricity, but also do something good for the environment. We save resources through precise planning.
