Unitests

I arranged this on behalf of my elderly dad to service his fireplace. I spoke with Patricia over the phone who was super friendly and offered really good advice. Josh was the technician and provided exact time of arrival. Feedback from dad was that he was the most nicest, honest and friendliest person. He was really thorough and sorted out the… Read more

fireplace for him. Thank you Josh for giving my dad a hug after learning that he was recently widowed. That was so kind of you.

Thank for also providing photos and video of the repairs. We would 110% recommend Josh and Unitests to anyone.

Gerald arrived at the suggested time, and worked for over two hours to clean our two ovens. When he was finished, the ovens looked brand new. We are happy to recommend Unitests to others.

I rarely write negative reviews, but this one is a must-avoid. The service was so poor that it bordered on fraudulent. They arrived at our house and immediately charged us almost double the initial quote. They then left without addressing the problem. When we reached out for assistance, they ignored our emails and phone calls. Finally, we managed… Read more

to get through to them, but the guy named Tim was rude and demanded more money to fix the problem that they hadn’t even fixed in the first place.

I strongly advise against using this service.

I am so pleased with the work that Uniests has done for me. The clarity of their advice, enabling me to understand choices with my gas heater - to repair? to remove? to replace? -their prompt and excellent service, their service person on time,… Read more

careful and thoughtful in his approach. So very grateful for all that they have done for me. I highly recommend them and thank them

Excellent service from Patricia whom organized josh to come out and service my gas log fire he was wonderful very friendly and hard-working removed all parts and cleaned ,tested and reassembled every part after cleaning , explaining what l needed to know about heating, I was so impressed with this exception service I highly recommend this company and will be using them in future

Had my Split system cleaned and checked and my celing ducts cleaned. Fantastic service from Patricia who genuinely cares and takes time to explain everything,answering all my questions and offering her experience so I got the best results. Van and Lian really took care with the services. Must appreciated!

Exceptional customer service and quality work. Communication was on point, efficient in the job and went above and beyond to ensure I was happy with the outcome. Highly recommend.

Great job, took his time and everything was done within half an hour. I couldn't remember how the carbon monoxide test was done, but the last guy from elsewhere was finished in 10 minutes and said there was no CM poisoning here! Should've traded his gas services for a crystal ball! Thank you Unitests.

We had an issue with our gas log fire which another company had caused more issue with, called on Unitests who came out and fixed up the problem without any problem. Josh is great!! Highly recommend

Had Josh come out and do our evap aircon service, he was super friendly and got the job done wonderfully and without a fuss! Even when I had a follow up question after he left he was quick to respond and happy to help. So happy with the service and will definalty be using Unitests again Thanks guys!

Service was amazing from making a booking to service completion. On time, thorough and sent photos and report of what was done. Have already recommended Unitests to friends. Customer service was outstanding which you don’t often get these days. A pleasure to deal with.

Smell of dead mouse/rat coming through heating ducts. Duct Doctor arranged prompt visit; technician Lien arrived on time and completed thorough cleaning of system. He was courteous; took care not to damage the ducts; and left the place clean and tidy.

I’m very happy with the techs who cleaned my ducts. They were professional, polite, and incredibly thorough. I couldn’t believe how much dust came out of my duct system, it was unbelievable to see what had been building up in there! The team explained everything step-by-step, worked efficiently, and left my home feeling noticeably fresher. Great service from start to finish! Highly recommended!

Quick response to my service request. Arrived on time and fixed the problem with my ducted heating system, then gave it a full service. They were very professional and experienced.

I rang Unitests and was amazed how quickly they organised the visit. Previously I had rang so many places and just found it hard for anyone to come and have a look. Service man came exactly at appointed time. Very happy with their service and service fee and would highly recommend them.

Excellent service from first phone call to finished job!! Communication was the key … always kept in the loop as to when technician was coming, result and further action … very professional company!!

Great friendly service. Super easy to book, service guy arrived on time and provided notice of his arrival. Got the job done quickly with minimal fuss and cleaned up after himself. Would recommend and use again.

Josh from Unitests serviced our central heating and was fantastic from start to finish. His communication was clear and prompt, and the service call rates were very reasonable. He demonstrated impressive product knowledge, quickly identifying an issue that had been missed during a previous service from another provider. Highly recommend these guys — professional, thorough, and great to deal with.

We have used Unitests many times for new installations and servicing and always found them to be reliable and the work they do is excellent. Happy to recommend them.

Used Unitests when we had a problem with our ducted gas heating system on a cold Melbourne winter's day. Trish, who took my call was wonderful. Communicated well, took me through their process and [thanks to a cancellation] had a plumber to us that afternoon. Josh the plumber messaged before he arrived, Was communicative and excellent to deal… Read more

with. FIxed the problem, serviced the unit and had us back in the warmth within the hour.

Winning on all counts. I highly recommend this service.

On contacting this company I was pleasantly surprised with the efficient manner they dealt with my problem. I had to replace all ceiling ducts from my evaporative cooling system. They have sufficient suppies of models they carry in the technicians van so it met my needs as I had three different sized vents. The admin person (Patricia) was very… Read more

helpful and knowledgeable. Unfortunately when the day came to replace the vents I was told by the technician that one vent was a much larger size and were no longer being produced. After a quick call to the company I was informed they would have to source a vent from elsewhere.

A booking was made for the second visit within one day and I had agreed to have the ducts cleaned with their sanitisation system. The duct technician arrived on time replaced the last vent and cleaned the ducts all within an hour or so. On both visits the technician was pleasant and he cleaned up afterwards. All in all the service was professional and the cost was reasonable for what I had done.

I had a very bad experience recently with this company. I called them for service of my Illusion Luminar 3000 series gas log heater on 11th March 2025. I believe their contractor did a good job and told me everything was perfectly well and even installed a switch on the side for simply switching on the heater from the pilot mode, which made things… Read more

easier.

However, I stay in Melbourne and this year the autumn/winter has been delayed in Melbourne, so just recently in the past two weeks started to switch on the heater. After two weeks of operation, I actually realised that the Fan doesn't switch to High speed when the fan switch is toggled to high and the heater doesn't give out the heat that is usually expected on a high speed fan. It doesn't produce any sound or indication that it has been switched on a high speed fan.

So, I called the Unitest team about this issue today and asked them to have a look as this is happening post their service and the fan speed was not an issue before the service. The person I talked to was not understanding at all and kept on asking me to pay for this simple callout to check after their post service which is not a long time ago, especially given the late onset of autumn/winter in Melbourne this year. It's not like I am asking 6 months after the post service to have a look.

Extremely unprofessional way of talking to the customers without even considering the actual context of where the customer is coming from and what complaint they have post their gas heater service. The company seems to have a strict policy on just charging the customer irrespective of their service and the complaint that the customer is asking for.

Moreover, the operator at unitest said that they have a lot of calls to go through and they don't have time to discuss on my request. Just kept telling me that book the call out fee of $250 for checking this issue out. What if the issue is caused by their service or what if there was a mistake discovered that the fan switch was somehow not completely connected during their servicing? Is that the customer's fault? Why should the customer pay for this callout fee then?

The operator just didn't want to discuss anything and listen or even carry on with the conversation at all or provide any alternatives at all. Just want the customer to pay the callout fee.

Extremely unsatisfied with their post service performance and would highly recommend to at least change their operators team to the staff who are patient and willing to talk to customers.

Edit and specific addition to the complaint: I would also like to mention that the operator told me that they have a lot of customers and calls that they have to attend to in the middle of my call and they don't have time to listen to my request and my context. If I want them to come check out the problem I need to pay $250 straight up.

Okay, here is question for you: What about the customers you already served and who paid for your service? They mean nothing to you now right as you have been paid.

Unitests fixed and serviced my 50 year old Vulcan gas heater. They were excellent to deal with from initial contact to serviceman who came out to service the heater. Service like this is very rare nowadays. Congratulations on your great service.

I recently engaged Unitests to service my gas fire place. Communication was really good and the process was efficient. The technician arrived on time, he was knowledgable, friendly and thorough in his work. They were also very reasonable. Highly recommend

Great service. Rang ahead and came early, to review and service the unit, and clean the return air filter etc. Checked the output in all the vents around the house. Provided a test report at the end. Would have no trouble recommending UniTests again

Customer beware - lack integrity in the way they do business – I normally won’t leave reviews. But for this one it is necessary for other potential customers considering using Unitests. Please double check that all the parts Unitests recommended repairing/replacing are indeed necessary. They put a quote together including items which were not needing to be replaced after a service. We verified the… Read more

recommendations with two other technicians who told us that the unit wouldn’t simply giving you cool air if these two items aren’t working. Unitests also told us that these parts are phasing out which are not true upon confirmation with one of the suppliers and had done a bit of google research to check them myself.

Unitests recommended us to change the unit they subsequently put forward as they claimed that the current one is too old (less than 15 years old). An evaporative cooling system of this age is not too old by the industry standard. So, please double check all the recommendations are necessary. We ended up using a different company to follow up and saved us 60% of the cost vs the quotation provided by Unitests.

Lack of integrity was the conclusion from the subsequent technician. Just be careful!

Arrived on time and provided excellent service. Clearly explained all procedures required.

Great service. Honest. Reliable. Very knowledgeable. Very friendly and helpful. Would highly recommend
