How often should commercial AC units be serviced?

Most commercial systems are serviced quarterly or twice yearly depending on usage intensity and manufacturer requirements.

Do maintenance contracts cover breakdown repairs too?

Some contracts include priority breakdown response, others cover scheduled maintenance only with repairs quoted separately. Check what's included before signing.

Is a maintenance contract worth it for a small office with two split systems?

It depends on usage, but even small sites benefit from regular filter and coil cleaning to avoid efficiency loss and unexpected breakdowns.

Ongoing commercial HVAC maintenance contracts

Offices, retail fitouts, warehouses and strata buildings often need a standing service arrangement rather than calling a contractor each time something breaks. This covers scheduled filter cleans, refrigerant checks, coil cleaning and compliance reporting across multiple rooftop units or split systems on one site.

Multi-unit sites needing a single point of contact
Strata and body corporate common-area systems
Businesses wanting a maintenance log for warranty or compliance purposes

This is distinct from a single emergency callout or a one-time repair: it's an ongoing arrangement covering a whole property or portfolio.

What it costs

Maintenance contracts are usually priced per site or per unit count and scale with how many systems need covering and how often they're serviced (quarterly vs annual). Larger commercial rooftop plants generally cost more to maintain than a bank of split systems.
