Designed for Performance
& Efficiency

A reliable air handling unit is at the heart of any ventilation system, controlling airflow and maintaining air quality throughout the building. At AVS, we supply and install high-performance AHUs built to deliver consistent, efficient ventilation on projects of all sizes. Our focus is on systems that balance air distribution, minimise resistance, and stand up to long-term use — keeping your building’s ventilation running exactly as it should.

Tailored AHU Installations

Every building demands a carefully balanced ventilation system. Poorly installed or mismatched air handling units can cause inefficiencies, higher running costs, and compliance issues. That’s why AVS works closely with clients to deliver AHU installations designed to suit each project’s exact airflow requirements. From large commercial builds to industrial facilities, our systems are specified for maximum efficiency, easy integration, and long-term reliability.

Pressure Testing for Compliance and Performance

Effective ventilation is about more than just moving air — it’s about proven performance. At AVS, we carry out professional pressure testing to ensure every system meets strict building regulations, fire safety standards, and performance targets. Our testing identifies any leaks or inefficiencies, giving you confidence that your AHU installation is operating exactly as designed. Working alongside contractors and project teams, we make sure every system is fully compliant, efficient, and ready for handover.
