Hi. We are CTA.

With heat pumps, air-conditioning units and chillers, we ensure that the temperature and climate are right – for people and for nature. As an independent, family-run, Swiss company with more than 200 employees, we have been committed to renewable energies and energy-efficient system solutions for heating and cooling buildings since 1981.

We are your Swiss quality manufacturer

  • for sustainable and efficient air-conditioning, cooling and heating

  • high-quality products using renewable energies

  • family-run and independent

  • located in Switzerland and locally based

  • there for you throughout Switzerland


Located in Switzerland

From mass-produced industrial heat pumps to standardised domestic heat pumps, we develop, manufacture, install and test environmentally friendly heating systems and chillers at our headquarters in Münsingen, Bern. That’s our contribution to the renewable energy transition. And it’s our contribution to Switzerland as a workplace.

Environmentally responsible

Not only our products, but also our actions should be environmentally friendly. As much as possible, we use sustainable materials and ensure that waste is properly separated and disposed of in the right way. We promote the use of natural and climate-friendly refrigerants and are careful in our use of natural resources. We obtain most of the energy for our production in Münsingen, Bern from our rooftop photovoltaic system. Our premises are heated with air source and ground source heat pumps. 


Environmentally conscious since 1981

For more than 40 years, we have consistently focused on sustainable system solutions and the use of renewable energies in air-conditioning and the cooling and heating of buildings and production processes.

Skilled knowledge and experience

We ensure our quality and technology standards through the continued training and further education of our employees. Our plant and our heat pumps are tested and awarded according to international quality standards and certificates. 

The people behind CTA

We cultivate a family-like corporate culture and look after each other – this includes our trade partners and suppliers. As a company, we are rewarded for this with a minimal and healthy turnover of less than 5%. As a customer, you benefit from the long-term support of our experienced staff.

We support young talent 

We train apprentices in three learning professions and contribute to supporting young talent in the sustainable energies sector and promoting future-oriented professions.
