  • Pioneers throughout the years

    Foundation of Réfrigération & Chauffage Longueuil Inc.1969

    In early 1969, Gabrielle and Emmanuel Bastrash founded their refrigeration and heating company by setting pillars and values that were to be transmitted in every action. From this moment, their primary desire was to offer sustainable and cost-effective solutions to their customers in the Montreal area.

    Purchasing of the Demers Plumbing Division1972

    When the opportunity to considerably expand the service offering for full-customer satisfaction arises, we acquired Demers Plumbing division. This action is full of promises for the company’s future, evolving eventually into Réfrigération, Plomberie & Chauffage Longueuil Inc.

    Broadening of the service offering1982

    Even though the eldest Bastrash son, Serge, started working for the company in 1975, he took over the business in 1982. His vision and passion push him to expand the service offering in the refrigeration industry in order to serve both residential, commercial and industrial customers.

    First 100% energy recovery supermarket1985

    Back then, heating an entire building with heat generated by a refrigeration system was unheard of. Thanks to the trust of an optimistic customer, we were able to install a pack fully equipped to recover 100% of the available energy and heat a whole supermarket without any auxiliary system. An absolutely unprecedented achievement at the time!

    Foundation of Klimfax Inc. 1994

Paired to an easily identifiable fleet of yellow trucks throughout Quebec, the new image achieves instant success.

    Alain, one of the Bastrash brothers, joined Serge a few years earlier and now works with him to build a 40,000-square-foot complex located at 800 Trans-Canada in Longueuil, half of which is used for the company needs. Despite the banks’ pessimism considering the scope of the project, the company continues to grow quickly, hence space still being an ongoing issue one year later.

  • Pioneers throughout the years

    Development of Zero-C trademark2011

    Faced with the magnitude of the company’s growth, the executives divided the operations into two separate companies with exclusive shareholders.

The residential ventilation, air conditioning and heating division remained with Klimfax Inc. under new ownership.
