Air Handling units (AHUs) are critical in purifying and maintaining optimal climate conditions within buildings or premises. AHUs come in various forms, ranging from basic units designed to maintain a common supply and extract air stream to a room or office floor, or to control temperatures and conditions of close proximity rooms. Failed drive belts or blocked air filters are the most common faults we find with AHUs, however regular service visits will ensure optimal conditions are maintained throughout the operation of the AHU. Simons Ventilation & Refrigeration Services can offer pre-planned maintenance programs tailored to your requirements, cover call-out visits and carry out remedial works.
