About Us

Proff Installasjon AS is an F-gas certified specialist in refrigeration and air conditioning technology, established in 2015 by the couple Michaela and Jan Mastalir. The company is family-owned and is still run by the founders, who from the start emphasized long-term quality and personal follow-up.

Over the years, Proff Installasjon has built a strong reputation for quality work and good service, which has allowed us to collaborate with some of the largest international and Norwegian companies in the industry. Among other things, we have contributed to the reconstruction and modernization of over 300 stores throughout Norway, an experience that has given us unique insight into effective solutions for retail and commercial premises.

Our goal is to be a reliable total supplier that delivers high quality, good communication and professional implementation - from planning to completed facilities.
