The Beaver brand was established in 1967 by an Australian-Canadian husband and wife team. The name Beaver Air Conditioning was chosen in acknowledgement of the tireless and hardworking beaver, native to North America. These hardworking traits are embedded in our work ethic today.

Old fashioned tower

James L Williams was established in Melbourne in 1875. Originally focused on gas lighting, in the 20th century it became a pioneer of commercial air conditioning. The NSW business grew and prospered with many large and prestigious projects completed. These included Governor Phillip Tower and several regional hospitals.
