ASG’s Service and Maintenance division is one arm of a wider group of companies committed to delivering excellence in Heating, Ventilation and Air Conditioning (HVAC). We understand that reliable, efficient systems are vital to your operations — and we’re here to keep them running smoothly, around the clock.
Our fully trained service engineers provide a 24-hour, 365-days-a-year emergency call-out service for breakdowns and repairs. We also offer comprehensive planned preventative maintenance (PPM) programs, covering not only our own installed equipment but many systems from other leading manufacturers across the industry.
Clients with a maintenance contract in place enjoy exclusive benefits, including discounted labour, travel, and parts, reduced refrigerant costs, and access to free technical advice. You’ll also have a dedicated Contract Manager and Service Coordinator to ensure seamless communication and tailored support whenever you need it. With ASG, you’re not just getting a service — you’re gaining a long-term partner in performance and reliability.
We’re committed to building lasting partnerships with our clients by delivering consistent results, expert guidance, and complete peace of mind. From routine maintenance to emergency support, our team is always on hand to keep your systems operating at peak performance while minimising downtime and costly disruptions.
By taking a proactive approach to servicing and repairs, we help extend the life of your HVAC equipment, improve energy efficiency, and ensure full compliance with industry standards. Our goal is to remove the stress of managing your heating, ventilation, and air conditioning systems, so you can focus on what matters most — running your business.
