Our story

Multiclima since 1989. The next generation is called Climaventis.

We started in 1989 as a heating store. In 2011 we opened multiclima.gr. Over the years we created our own brands and a network of partners across Greece. Today the next generation of the family carries on under a new name. The people, the store and the service stay the same.

“With many years in heating, our business is passing to the next generation. Now it is our turn to take it further with the same reliability, offering quality products and responsible service.”
Theodoros Spyropoulos, the next generation of Climaventis
