Trusted HVAC & Commercial Pool Heating Consulting for Critical Decisions
With over 35 years of hands-on experience, Mark Greentree provides technical consulting across all aspects of commercial HVAC and pool heating. His expertise helps councils, engineers, architects, builders, insurers, and HVAC businesses to improve scope design, assess compliance, troubleshoot issues, and deliver better outcomes in less time.
Mark regularly reviews tender documents and technical specifications, identifying risks such as inefficient layouts, poor serviceability, or excessive complexity. His insights will help government and private clients avoid costly redesigns or underperforming systems — especially in aquatic facilities, strata buildings, and high-risk public environments.
Mark’s trade experience delivers rapid and effective results. In one recent case, Mark was engaged informally to assess a newly signed-off carpark ventilation system in a residential strata complex by a concerned strata committee. Despite having been certified, Mark immediately identified the system was not compliant with current strata fire safety regulations and was actually operating in reverse! His deep understanding of HVAC and ventilation system logic, combined with a few targeted wiring and control fixes, resolved the issue and restored compliance.
