A new split system in Australia has three layers of cover: the automatic consumer guarantees under the Australian Consumer Law, the maker’s air conditioner warranty, and the installer’s workmanship warranty. Haier, Mitsubishi Heavy Industries and Daikin each give five years on a home split system. Every split system we install also carries our 5 year workmanship warranty.
The quick answer
- Haier, Mitsubishi Heavy Industries and Daikin each give a five year warranty on residential split systems, with conditions.
- Both Daikin and Mitsubishi Heavy Industries tie their warranty to correct, licensed installation.
- Our workmanship warranty is 5 years on split system installations.
- Consumer guarantees can still apply after a warranty ends, for the reasonable life of the product.
What does an air conditioner warranty cover?
A maker’s warranty covers faults in the product. The installer’s warranty covers the installation work. The consumer guarantees sit under both, and nobody can take them away.
| Cover | Who gives it | What it covers | How long |
|---|---|---|---|
| Consumer guarantees | The law, through the business and the maker | Goods of acceptable quality, safe and durable. Services with due care and skill. | The reasonable life of the product |
| Maker’s warranty | The brand | Defects in the system, on the maker’s terms | Five years for the three brands we install |
| Workmanship warranty | The installer | The installation work | 5 years on our split system installations |
The Queensland Government’s Office of Fair Trading explains the difference on its types of consumer warranties page. A warranty is a promise the business chooses to make. The guarantees apply whatever warranty you get.

Installation decides whether the warranty holds
Two of the three makers name installation in their conditions. Daikin’s warranty doesn’t cover faults caused by installing the product incorrectly or not in line with the installation manual.
In Queensland a split system install needs two licences: an ARCtick licence for the refrigerant and an electrical licence for the wiring. We hold both, ARCtick L181564 and electrical contractor licence 90552. You can check any refrigerant licence on the ARC licence check.
Our 2.5 kW split systems are supplied and installed from $1,814.51 including GST. The air conditioner installation cost guide sets out what’s included, and every air conditioning installation in Brisbane we do carries the 5 year workmanship warranty.
Common air conditioner warranty exclusions
Each maker publishes its own exclusions, so check the terms for your model. Daikin lists these on its what’s not covered page.
- Faults caused by incorrect installation, or installation not in line with the manual.
- Consumable items, such as batteries.
- General maintenance, such as filter cleaning.
Maintenance is yours to arrange. A split system service and clean is $341 including GST for one unit, and our air conditioning service Brisbane page lists what’s covered.
Your rights when the warranty runs out
The consumer guarantees don’t stop when the warranty does. The Office of Fair Trading says they apply for the reasonable life of the product, even after other warranties have run out.
What the Queensland Government says
- The business that sold you the product must help you. It can’t refuse by sending you to the maker.
- A major failure lets you choose a refund, a replacement, or compensation for the drop in value.
- For a minor failure, the business chooses whether to repair, replace or refund.
- Keep your receipts, invoices and warranty documents as proof of purchase.
Read the detail on the when a business fails to meet a consumer guarantee page.
How to make an air conditioner warranty claim
- Gather the paperworkFind the invoice, the model and serial numbers, and the warranty documents.
- Contact the right partyStart with the business that sold or installed it. For a product fault, the maker’s claim process applies.
- Let the authorised agent repair itMitsubishi Heavy Industries requires repairs by its nominated service agent to keep the warranty valid.
If we installed your system, contact us first. We’ll check whether the fault is in the installation, which our workmanship warranty covers.
Common questions about air conditioner warranties
Is an extended warranty worth buying?
Think before you pay. The Office of Fair Trading says extended warranties are optional, and you shouldn’t pay for something that’s already your legal right.
What does your workmanship warranty cover on electrical work?
Our workmanship warranty is 12 months on electrical work and 5 years on split system installations.
Can I install the system myself and keep the warranty?
No. Mitsubishi Heavy Industries says its warranty is voided without a licensed ARCtick installer, and refrigerant and wiring work in Queensland both need a licence.
Our advice
Have the system installed by a business that holds both an ARCtick and an electrical licence, because two of the three makers tie their warranty to correct installation. Keep the invoice and warranty papers together. If something fails after five years, your consumer guarantees can still apply.
