Daikin Australia Reviews 

We have a Daikin Reverse Cycle Air-conditioner that has worked well for many years. We decided to get it serviced as it was making some noises and not working properly on the heating cycle. The technician subsequently came to our site on 1st April, 2026 for which we were charged $253. The Service report said: 12 month warranty on parts and 3 month warranty on labour. Subsequently, on 10th April, I reported that it was still not working properly and had an email exchange with the technician: (who was initially very helpful). We continued to use it in heat mode over winter and although it functioned OK, it wasn't great. In the last few weeks however, the heating mode continued to get worse and eventually stopped heating altogether, just blowing barely warm air so I contacted Daikin Service again via phone first on 28/9. The person who answered the phone was rude and was only interested in booking another service call that I would have to pay for. I noted the warranty terms that were on the service report: "12 month warranty on parts and 3 month warranty on labour.", but was told this was irrelevant and that I should send an email if I wanted to follow it up. I sent the following email later the same day to the email address I was given:
'service-at-daikin.com.au'
Hello Daikin Service, I’m disappointed to report that over the last few weeks this unit has again started exhibiting the same problems it did immediately after the service and now fails to heat effectively at all. I was even more disappointed when I contacted your service team to be told that our Air-Conditioner is not under warranty and that we will have to pay again for a service call. This was despite me highlighting to your support person your own explicitly stated terms in the service report of: “12 month warranty on parts and 3 month warranty on labour.” She advised me that this warranty does not apply as the unit is no longer under warranty and that I will have to pay again if I would like to get someone to come out and investigate. She was also very dismissive and rude, made no effort to actually look up the service report and demonstrated no interest in anything I was saying other than to quote for a new booking and refer me back to this email address for any other concerns. This response suggests that Daikin is not prepared to stand behind the service they provide, or to honour their written warranty which doesn’t give me any confidence to book again or to recommend any of your products and services in the future. This is especially concerning given that I raised concerns immediately after the service about heat mode not working properly. Please advise my options to get this addressed. Thank you.

It has now been 10 days and I have not even received an acknowledgement from Daikin, let alone any response.

If you are thinking of using them to service your air-conditioner, don't bother as they won't fix anything and won't honour their warranty.

A Daikin ducted air conditioning system was installed in 2020–2021 while the previous owner/builder was renovating the house. We first noticed increasing noise from the system during winter 2024, shortly after we purchased the property and moved in. As we do not use the air conditioning system very often, we initially put up with the noise.

In July 2026, I decided to contact Daikin Australia (NSW office) to report the issue. About 10 days later, a technician attended the property. He spent only a few minutes inspecting the system from an access opening upstairs and concluded that the noise was caused by poor installation. He took two photos showing squashed ducting near the return-air grille and a short video of the inside of the ceiling where the fan is located. He completed the job report online and forwarded it to me.

I specifically asked him to inspect the fan because I suspected that it was the source of the noise. He had only a quick look and then told me that there was no access to the other side of the fan, and that Daikin did not have the insurance coverage required for him to access that area. As a result, I paid a call-out fee for an inspection that did not identify the actual cause of the problem.

I then contacted a local air conditioning company for a second inspection and to see whether there was a possible solution. Their technician went into the roof space, spent about an hour investigating the system, removed the cover of the indoor fan, and determined that the fan itself was making the noise.

He then gave me several options, including replacing the fan at a significant cost, carrying out a full maintenance service costing nearly $1,000, followed by annual maintenance. I decided to pay only the call-out fee as the offer of all services are outregesly expensive. I also believe I should not have needed to pay for a second inspection if the Daikin technician had properly inspected the fan in the first place.

I am now in a very awkward situation. If I spend thousands of dollars replacing the fan, I am concerned that the underlying poor installation—including the squashed ducting—may continue to put excessive strain on the system. The same problem could potentially occur again within another two or three years.

Given the circumstances, I am now considering whether it would be more sensible to install a couple of split-system air conditioners instead (Not Delkin Brand), Split systems would generally last for many years and may avoid the ongoing problems associated with this ducted system.

My main concern is why Daikin would certify or approve installers who carry out such poor ducted air conditioning installations. I would expect a ducted system to be properly designed and installed in accordance with Daikin's requirements, including appropriate duct sizing, airflow and installation standards.

If the current faults and excessive noise are the result of poor installation, I believe Daikin should take greater responsibility for the situation. I would appreciate Daikin explaining why this system was installed in this manner, whether the original installation complied with Daikin's installation requirements, and what responsibility Daikin is prepared to take for correcting the problems.

Awful under warranty experience. Like much of Australia's population I live by the bay. I have copied part of their response to me. If you live near the sea, as far as their warranty is concerned, their Air conditioner outdoor unit isn't fit for those conditions. This unit has needed to be repaired at the end of year 1 and year 2. Never Buy a Daikin!
"The manufacturer’s warranty includes specific provisions relating to equipment installed in hostile or corrosive environments, including exposure to salt air. The warranty also outlines certain responsibilities for the equipment owner regarding ongoing maintenance and care.

Moisture, salt and other foreign matter entering the condenser is not a defect of the air conditioning unit. The impact of salt in the air is a factor that should have been considered by your installing contractor."

I hope someone learns from my mistake and avoids this brand!

Atrocious product & even worse service.
Multi head unit leaking refrigerant only just over 5 years from 2 out of 3 Heads. Installation is in a passive house so never even gets used that much. Purchased by builder in 2019, we took possession in 2020.
Daikin have a lousy 5 yr warranty from date of sale compared to industry 7 yr standard. Repair guys confirmed leaks & said manufacturing fault. Asked daikin to repair under ACL & they refused- NEVER EVER BUY DAIKIN & AVOID AT ALL COSTS

Never a Daikin again – Extremely poor service and questionable parts

1 out of 5 for both Daikin Australia and LJ Air (Would give -10 if possible)!

I purchased a Daikin Australia split system air conditioner expecting reliability and professional service. Instead, I experienced a frustrating and poorly handled repair process when the Condenser Unit’s main circuit board burned out along with two other key parts and needed replacing after only four years, despite the unit being under the manufacturer’s 5-year warranty. This meant 4 of our 6 interior units did not work at the start of and during a multi-week heatwave. This was a $15,000 investment, that was regularly service annually at an additional cost of over $2000. That’s a 66% failed investment. A $11,332 failure in less than four years I can’t “just right off” like a corporate business.

The service experience with both Daikin Australia and their contracted service provider LJ Air was extremely poor.

First, Daikin staff or their representative/General Council De Fries, never acknowledged any wrongdoing or incompetence during or at the end of the entire process. Despite clear evidence of communication failures, missing information, and delays, Daikin consistently dismissed the issues and insisted their service was “more than acceptable.”

In particular, Mr De Fries and Andrew were rude, dismissive or both, repeatedly downplaying the impact the delay had on my family during a multi-week heatwave. Rather than addressing the actual service failures, they focused on defending internal processes and explaining how busy their service centre was.

The situation was made worse by conflicting and questionable information about when parts were received and shipped. Daikin claimed the replacement parts were delivered to LJ Air within two business days, yet Luke from LJ Air told me days later they were still waiting for answers.” This raises serious concerns about whether Daikin and LJ Air were being truthful about the parts timeline.

Luke from LJ Air also failed to contact me promptly once the parts allegedly arrived, despite promising he would book the repair as soon as they were received. Instead, I had to keep chasing both companies for updates.

What is most frustrating is that neither Daikin nor LJ Air ever initiated follow-up communication. In every instance, I had to initiate contact just to find out what was happening with my warranty repair. Without repeatedly following up myself, it is entirely possible the issue would have taken weeks longer to resolve.

Basically:
1 - Major components failed within 4 years.
2 – There was poor communication and inaccurate information from both Daikin and LJ Air.
3 – I got conflicting statements about when parts were received and shipped.
4 - Broken promises from Luke at LJ Air regarding contacting me once parts arrived.
5 - Rude and dismissive responses from Daikin staff and executive representatives.
6 - No accountability was taken by Daikin or LJ Air.
7 - No proactive follow-up from either company — I had to chase every update.

Even after lodging a formal complaint with Daikin Executives, Daikin refused to acknowledge any failures and declined to take responsibility for the actions of their contracted service provider LJ Air who, to date, have ignored me and not acknowledged receipt of my complaint or provided feedback or a response.

For a premium air-conditioning brand that markets itself on quality and reliability, the customer service, communication, and accountability shown here were extremely poor.

If this experience is representative of how Daikin Australia and LJ Air handle warranty repairs, I would strongly encourage potential customers to think carefully before purchasing. Buy a Mitsubishi, LG or Panasonic but NEVER a Daikin.

Product is fine - when it’s working - but as soon as you want a spare part expect to wait over a month.

You’d think they would anticipate that in Australia in Jan and Feb a few spare parts on hand would be a smart idea!!!

Constantly breaks down. Takes up to 5 technicians and two months to fix.
Forced to buy heaters in winter and coolers in summer.

I am on my second ducked unit and this has broken down twice with the same fault,dakin are crap ,service is crap, help crap

Hi my 16KW aircon unit had a faulty wolf valve which is a manufactueing issue which caused all my gas to leak and the expansion valve to fail. My compressor is now running at 25% after $2600 to fix to this point. I am looking at a further $5000 to fix. The unit is 6 years old and Daiken are sticking to the 5 year warranty, not even an offer to get a reduced rate on parts. 2 weeks of emails and calls still with no reply. Terrbile product and and even worse after service.

Off to consumer and offcie of fair trade as this is a faulty product they have sold.

Don't buy Daikin.

Two new air conditioners failed within a year. Appalling customer service. Manufacturer’s fault as both have gas leaks. Daikin have dragged their heels fixing them under warranty and it is 4 months now and still not fixed. Daikin will not contribute to the cost of the roof removal as both units need to be removed. A nightmare and not one that goes with a supposedly good brand and very expensive air conditioners, I would avoid Daikin products in future. Installers said gas leaks are becoming an issue!
