Damien Simpson

Director, Simply Cool Air Conditioning

Licensed HVAC & Refrigeration Specialist | ARCtick–Authorised Professional | Energy Efficiency Advocate

For more than three decades, Damien Simpson has set the benchmark for professionalism, precision, and performance in Western Australia’s air conditioning industry. As the founder and Director of Simply Cool Air Conditioning, Damien has spent over 33 years mastering the art and science of HVAC — delivering tailored, energy-efficient solutions that stand the test of time. Since 2001, his vision has guided Simply Cool to become one of Perth’s most trusted and compliant providers across residential and commercial projects.

Damien’s expertise extends far beyond installation. His leadership combines deep technical insight with a commitment to innovation and sustainability. Every project — from complex ducted systems to complex commercial upgrades — is designed and delivered with meticulous care, meeting Australia’s highest standards for efficiency, safety, and long-term reliability.

Under his direction, Simply Cool operates with full Arctick accreditation (RTA AU57376), the national authorisation required for businesses handling fluorocarbon refrigerants. All technicians hold the Refrigerant Handling Licence (RHL), and in Western Australia, work is performed under a Restricted Electrical Licence (REL) — ensuring complete compliance from electrical connection to refrigerant management. These standards are not optional to Damien; they are non-negotiable.

What sets Damien apart is his hands-on, problem-solving mindset. Raised in the Wheatbelt and surrounded by machinery from a young age, he developed an intuitive understanding of how systems work — and how to make them work better. That background shapes his approach today: diagnose precisely, design smart, and deliver with integrity. His commitment to energy efficiency and fit-for-purpose design has helped thousands of Perth homes and businesses achieve year-round comfort while reducing energy waste and cost.

Damien is a proud dad of two and brings that same care to client relationships: educating customers, prioritising lifetime value over short-term fixes, and standing behind every recommendation. His clients describe him as approachable yet uncompromising — a leader who listens first, explains clearly, and always delivers on his word.
