Service & Maintenance

Planned and reactive mechanical maintenance for multi-site estates. One contractor, one point of accountability.

What the
service covers

Most maintenance contracts look the same on paper. The difference shows up the first time something breaks out of hours.

ASG delivers planned preventative maintenance (PPM) and reactive breakdown cover across multi-site commercial estates. Our engineers maintain ASG installations and most major third-party brands, so clients can consolidate maintenance under one contractor without being tied to a single manufacturer.

Every contract comes with a dedicated team: a Contract Manager who owns the relationship, a service coordinator handling scheduling, and an account manager for commercial questions. Discounted labour, travel, and parts rates apply, with priority scheduling on reactive jobs. When something fails, the engineer who arrives already knows the site.

How we deliver it

Response times
Engineers attend with the right parts and knowledge to resolve, not just diagnose. Reactive cover runs 24 hours a day, 365 days a year.
Reporting
Compliance documentation, F-Gas records, and fault reporting handled proactively. Nothing lands on your desk without a resolution attached.
Technical breadth
Our engineers are trained across chillers, VRF/VRV, split systems, AHUs, and controls. Coverage extends across ASG and third-party manufacturer equipment. Technical depth on site, not triage for a specialist callback.
Communication
We assign a dedicated Account Manager, Contract Manager and service coordinator on every account. A direct line to someone who knows your sites, your systems, and your priorities.
