Heating, ventilation and air-conditioning service contracts are common in Australian strata buildings, commercial premises and increasingly in homes with ducted or reverse-cycle systems. The sales pitch is simple: pay an annual fee, get peace of mind. The contracts themselves are rarely that simple. The main problems are scope gaps ('cleaning is included, refrigerant is not'), auto-renewal language that locks you in for another year, and callout fees that turn a maintenance agreement into an expensive extended warranty.
What is a Maintenance Agreement?
An HVAC maintenance agreement is a service contract for the regular inspection, cleaning and maintenance of heating and cooling equipment, usually with discounted or included call-out response for breakdowns. In Australia, these contracts are subject to the Australian Consumer Law (Schedule 2, Competition and Consumer Act 2010) — consumer guarantees apply to services including due care and skill (s.60) and fitness for disclosed purpose (s.61). Licensing of HVAC technicians is governed at state level (e.g. Victorian Building Authority, Queensland's Electrical Safety Office, ARCtick licensing for refrigerant handling).
Red flags to watch for
Short notice windows trap consumers in another full term. The ACCC has taken action against auto-renewal practices in services agreements, and terms may be unfair under ACL s.23.
Most contracts exclude major parts. Check carefully whether common items (capacitors, contactors, refrigerant top-ups) are in or out.
Some premium plans double-charge: you pay the annual fee and a callout. Read the fee schedule, not just the marketing.
Without a response SLA, 'priority service' is meaningless. Commercial contracts should commit to hours; residential to next business day or similar.
If the service provider's own technician decides whether a fault is 'wear and tear' or 'damage', there is an obvious conflict. Contracts should allow independent assessment or dispute.
Common trap in commercial buildings — client pays for system-wide work while only named units are covered. Make the covered equipment schedule unambiguous.
Full acceleration on termination is unlikely to be enforceable under ACL unfair terms principles if services would not have been delivered.
Your legal rights
Australian HVAC service contracts are covered by the Australian Consumer Law, which imposes consumer guarantees on services including due care and skill (s.60), fitness for a disclosed particular purpose (s.61) and reasonable time for supply (s.62). Unfair terms in standard-form consumer contracts are void under s.23 — this has applied since 2010 and, since November 2023, can carry significant penalties against businesses. Electrical work must be performed by appropriately licensed electricians (state-based), and refrigerant handling requires an ARCtick licence (Ozone Protection and Synthetic Greenhouse Gas Management Regulations 1995). WHS obligations (e.g. Work Health and Safety Act 2011 in most states) apply when contractors work on commercial premises. Disputes can be taken to the Australian Consumer and Competition Commission (ACCC), state Fair Trading bodies, or tribunals such as VCAT.
Questions to ask before you sign

- 3How does renewal work, and what notice do I need to give to cancel?
- 4What is the response time for breakdown calls, in hours?
- 5Are there callout fees in addition to the annual charge, and when do they apply?
