I am very disappointed in the service I have received. As my solar has not been working since the 27 December 2024. When I call your offices and select option 2 or 3 my call just continues to ring out and no one answers and funnily enough when I select option 1 for new installs my call always gets answered by someone in the air conditioning department who informs me you weren't back from holidays until the 13th or 14th on January. After that date I started chasing you up and continuously got the run around by people saying they will call me back but no one ever did.
Eventually got someone to help and confirmed the inverter was buggered and under warranty and again was told I would hear from you about what was happening but I received nothing so I again had to chase it up. I got told you were waiting for a response from Growatt I was given a number and was told to chase up Growatt myself. After contacting Growatt I was told the inverter was not in stock. This is the second time that we have had a problem with an 8kw Growatt inverter when you installed it the first time it came out of the box faulty and had to wait 2 weeks for one due to none being in stock.
Growatt advised us it was delivered to your factory on Wednesday 25 February at 12.30pm and I waited until Thursday 3pm to call as I had not heard from you to be told that someone would check and call me back and once again no call back at all. When I started to call late the next day I received a text message that I have to wait until March 20 before I can get it installed which means I have had 3 months of peak sun with my solar not working. And as you know because I have solar on my house the power company charges me a higher rate for electricity that I use and I’m using all their power and none of my own.
I called them to say I was not happy and was told to email them with my complaint and once again I have had no response.
They are quick to install and get paid by the rebate and me but the after install and warranty service is appalling and leaves you frustrated and angry.
I would not recommend using this company for the your solar needs.

These people know there stuff they give you options to really satisfy your needs I wanted the split system ubove the old fire place but I didn't want the outdoor unit on the same side of the house as it will impact on the drive way so they arranged and advised me that I can have it on the other side of the house witch was out of site 😀 and it is within the specified range loved it and it works perfectly.
They also turned up on time and I was surprised how little time it took to complete. 👍🙂

Quote process and service was excellent from Sales Manager, Resh. 👍
Installation was great; James Installer very knowledgeable and helpful.👍
Compliance Inspection timely and efficient. 👍
LOVE MY REAL-TIME MONITORING APP that comes with System. 👍
Solar Victoria efficient with loan process and rebates system.👍
All good.
As a returning customer for the 3rd time, once again I highly recommend Online Air & Solar.
I called the office on Mon 2nd Dec to make an enquiry and a visit was booked for the next day, where we discussed the options available for my needs, quote given (fair price) my only stipulation was I required installation before Xmas (big ask I know, especially as how busy they are) several calls later it was organised (if I didn't mind the installation being over several days/possibly a Sat, I said I will rearrange my schedule to fit in with whatever is needed). Units delivered and installed Fri 6th and power connected Mon 9th first thing = exactly 1 week from initial enquiry call. That's what I call excellent service and everyone involved in the process were very professional, courteous and friendly. 100% recommend Online Air & Solar.
BATTERY INSTALLATION REVIEW Mar 2023
Again the installation guys were great, professional and friendly - arrived unloading gear bang on time at 0730am.
Showed me how to get the mobile app working and explained everything perfectly.
The Battery unit was installed very neatly and even with the safety pole, it is very unobtrusive.
They took all the packaging away so didn’t need to dispose of anything and even vacuumed up after finishing.
Highly recommend.
ps: the time difference between Panels + Battery installation was because initially I was only going to get Panels, then later changed my mind !
SOLAR PANEL INSTALLATION REVIEW Nov 2022
The team that did the installation were great, very professional and friendly - albeit there was a slight delay in the installation process due to COVID - install started 01 Aug (but solar panels not delivered) rescheduled for 4th, then 5th, then eventually the 9th and installation completed.
19 Aug Solar fitting inspection/approval completed.
They would have lost a star as there was a bit of a break down on communication between the office and the a/c dept, when I had an error with my invoice - numerous emails and phone calls later it was eventually sorted, ironically the error was in their favour.
As one of the companies owners took the time to contact me directly apologising for the communication glitch and that he would look into their admin and a/c's processes to improve/prevent this glitch occurring again, they regained the 5th star.
Technician did a no show on the day.
Wasted my time and disrupted my workday (twice).
Edit: Updating my review from 1 to 3 stars after the owner, Robert, personally reached out to apologise and explain the situation. He made an effort to address the stuff-up and clarified that the job was sub-contracted to DGB Refrigeration. Unfortunately, DGB Refrigeration was unable to commit to the job and caused scheduling problems, which resulted in wasting everyone's time.
While I appreciate Robert's apology and efforts to resolve the issue, the poor communication and scheduling failures by DGB Refrigeration reflect poorly on OA&S as their chosen subcontractor.
My recommendation for others to avoid my situation, would be to call ahead leading up to your appointment to make sure it is still going ahead for set date.
Thank you Online Air & Solar for a pleasant experience.
Great job, thank you very much
Alroy and the team advised us on what system would suit us for our home.
Then came the install, the team on the ground were as knowledgeable as the sales team and friendly.
It is a bonus when you have so many trades onsite at the same time and you notice the difference, we would recommend Online Solar to everyone who would appreciate a pleasant transaction with no hiccups.
Well done Online Solar team..
The online air and solar provided the service that exceed my expectations
Very polite people and explain very well the job to be performed and how it will work the new system
So excellent and qualified techs
They have installed solar system in my place at Wollert. Thanks a lot Rick
Great service & professional conduct
The lads on the crew did great work for my property and I'm already reaping the benefits even on these cold, cloudy winter days.

Yours Truly,
Anthony Gunn.
I just thought it would be very important for me to let everyone out there know, that Online Air Solar is the best company to deal with as far as solar is concerned. If you’re gonna put a Solar in your house or on top of your roof, online Air solar is the very best in this business. They are very professional, time management is excellent and customer service is ridiculously great. Resh was amazing in organising everything in a short period of time. Thanks Resh, good work, I’ll recommend you to anyone at any time.
So naturally, after our old hot water system packed it in, we didn't hesitate to seek out OAS again, and this time, it was even better. From Thursday's night when we found our hot water died to the phone call to Tanvir the next day, we had our brand new heat pump installed by Saturday's afternoon. We were beyond belief as we didn't expect to have done so much sooner.
So again, thank you very much to everyone at the OAS team, we really appreciated what you have done our family, and we wouldn't hesitate to recommend your service to anyone who'd be interested.
Also, a special mention to Steve from Trigger Plumbing PTY, without whom, all of this wouldn't have been possible. Initially, the installation was scheduled for the following week. After a quick chat with Steve, he went above and beyond to have his team arrived on Saturday morning to install the Heat Pump hot water system for us and completed the installation by midday. Once again, we're also very appreciative of you, Brydon and Lachlan in making it all possible in the short amount of time, super impressive to say the least, so thank you very much to you all.
They were floor and wall mounted indoors. Online Air and Solar made an effort with the aesthetics of the install, which I really appreciated as we recently renovated. Their guys were polite and efficient.
As for the Enphase batteries, they weren't the cheapest but I was looking for the LFP chemistry for longevity and I also felt that the Nectr plan was excellent value.
All up, very happy with the final sequence of SolarQuotes to Online Air and Solar and Nectr.
Following Resh's initial engagement, Jack conducted our onsite appointment, further solidifying our positive experience with his invaluable advice and outstanding customer support. We opted to upgrade to the sleek black racks to seamlessly complement our tiles, and the result is nothing short of impressive.
The installation team's efficiency was remarkable, completing the task swiftly without a single cracked tile. I cannot recommend Online Air and Solar highly enough. For those seeking the best value in the market without compromising on product quality or installation expertise, look no further.
Nothing to be desired more. I am quite happy with him.
The workers that came out and installed the Solar Panels were fantastic, couldn't fault them.
As for the company suppling the solar panels, I couldn't be more disappointed. After installation they were very hard to get in contact with, would be told someone would call us back but never heard anything.
After installation, we were never told when someone would come out to turn on our solar panels, therefore we missed when he came out.
Our solar was turned on by the 24th of December, we thought we were all good! However I have since received an electricity bill. I have now found out that this company never told my Electricity company that we have solar.
This has been yet another battle to attempt to speak to someone. Feb 2024 and still received no word of why my electricity company was not told sooner, and yet to resolve the whole issue. 19 Solar panels installed late December 2023 and still no benefits.
Other companies suggested that installation on a property like ours was going to be problematic- it was a 70’s unit with terracotta tiles. It was absolutely fine.
I strongly endorse this outfit. Thanks folks.
When we call the office to find out what is going on we are told somebody will call us back, not once has anybody called us back.
Its been over 2 months and we still have no idea when the system will be completed or how many more days somebody will need to take off work and then have nobody show up.
Always responsive, good installers, good competitive price and options to suit individual budget and system requirements.
Really happy with the quality of the install and after the fact care and support.
The good:
Professional team who knew what they were doing. Explained changes that needed to be made based on the initial proposal. The team also explained the step by step process. It took longer than expected to have the whole system installed (bad weather prevented them from getting on the roof) etc, but at the end the job was done well.
What could be improved:
There were lots of bits of ends of wires and screws lying around outdoors - I appreciate it was challenging due to rain and wind one one of the days but I thought more could have been picked up.
They were at my property early and finished up earlier than I expected. I highly recommend Online Air & Solar to anyone looking at getting solar panels fitted. Thank you to the whole team. 👍
Explained options available and worked out what was best suited to my needs
Felt like this was a trustworthy company
Would highly recommend
My Powerwall has been installed and the entire team was professional and they did an extremely neat job. They explained everything on the day and made sure all was perfect on the Tesla app before they left. I highly recommend Online Air and Solar and getting a Powerwall with Solar. I’m very happy.
An unhappy customer 😔
Update @ 22/08/23
It was unfortunate I had to write a review for things to be taken seriously. Somewhere down the line there was an internal miscommunication but I have to say that the response was prompt and they dealt with the matter in a very professional manner. Thank you.
I’m a happy customer again 😃
Excellent work ethics from the inspection team on how my inverter would be positioned and how the system would most work efficiently. Tyler was a delight
very friendly and professional service would recommend online Air & solar to everyone
Also the office communication was fantastic, if there was an issue it was sorted and dealt with immediately.
Great bunch of young guys. Many other companies can take a leaf out of their book.
Thanks for your great work guys.
From the great support with the application process and paperwork to the great work by the installation team.
Polite and pleasant team who cheerfully explained every step and ensured we knew exactly what was happening and how it all works.
Very happy with the entire process and looking forward to future savings.
Highly recommend these guys if you want solar, want to know more about it or are just thinking about it. They can answer all of your questions.
answering any questions and never makes you feel rushed ,
Highly recommended
