BVS was formed by experienced ventilation system design engineers and contractors, each with many years' practical experience in the heating, ventilation and air-conditioning (HVAC) industry. Using this knowledge and experience, we offer the most practical and economic solution to any air movement requirements within a building. Whether you require air for heating, cooling, humidification, industrial processes or meeting new industry guidelines, we are here to help. We specialise in full spectrum AHU services. Our engineering team pioneered the concept of refurbishing AHUs in situ - a cost-effective alternative to replacement.
