Our heater stopped working in June, right at the start of winter. We thought we'd be shivering all the way through the cold but Brent from Cool Runnings came to our rescue. He installed a brand new heater within two weeks of quoting our job and re-routed the existing ducting so that our living area actually felt warm and cosy. Brent did a fantastic job, all finished by early afternoon. I would highly recommend him to anyone who wants a genuine, reliable and efficient contractor.



Hi Stephen,

Delighted with my new Braemar heating system installed with speed by Brent of Coolrunnings who was pleasant and professional.

Hi Stephen,

Just wanted to thank you and Greg for getting my spa heater fixed yesterday.

It was short notice and it is Christmas and Greg came and did a good job to get the heater fixed. Greg is a good guy.

I appreciate what you did.

Phil - Putney

I had an ongoing problem with my central heating unit that was costing me a fortune to fix with another company. I called Hi-Tech and Steve came around and fixed the problem immediately and for a minimal cost. I have since used them to replace the unit and Roger was very accomodating, honest and professional. Thank you for all your help!

Renae Harrison - Sydney

When we replaced our existing gas heater it was 30 years old and Stephen from HiTech Gas services had kept it going for the last 5/6 years of it's life. He and Roger did a great job keeping it going, but eventually the unit failed and parts to fix were not available.
Stephen helped us research new options and recommended a couple of potential installers. We met with John Montgomery , he impressed us so much with his attention to detail and " perfection" approach"that he got the job.
Having read other reviews herein I concur with both K Duffy and A Pitman that John and Stephen were the best people for the purchase and installation.
Both these gentleman come highly recommended if you require a professional and competent approach to your installation.

After weeks of a middle of winter cold house and various "experts" looking at our (we rent) large outside gas install. Stephen came along, knew the problem straight away, ordered the part and we were warm again! Knows his stuff and gets things done. 5stars from me.

Michael Anderson - Mosman

Hi-Tech Gas Services was recommended to us by Brivis for service of our ducted heating system. Steve and Roger were able to solve some tricky issues with our system and also successfully installed a wi-fi controller. Their knowledge of the system, professionalism and perseverance were exemplary. We would highly recommend Hi-Tech and are very grateful for their work and attitude.

Kim - Lambton

Stephen Hamlyn of HI-Tech gave us three referrals to replace of heater system and we went with Cool Runnings Installations. Brent was terrific, doing the job in less than half a day, including checking and repairing our original ducting and giving me a complete rundown on how the system works. The work was done very cleanly and Brent was very polite and tidy. We are very pleased with the installation and the recommended Braemar heater works beautifully. We also are confident that HI-Tech will be there to help us if need be in the future.

Stephen Hamlyn of HI-Tech send us Spartan Plumbing to install a new Braemar gas heater for our central heating system. The whole thing took only half a day . The work was done very cleanly and Greg of Spartan Plumbing was very polite and skilful. We are very pleased with the installation and the recommended Braemar heater is very tidy and works beautifully. We also are confident that HI-Tech will be there to help us if need be in the future.

Raumann Gagnon. Lane Cove North

Hi-Tech supplied our Braemar ducted gas heater to replace our existing. Just in time to warm us for winter. T-shirts inside all year round! It's a very quiet and easy to use system.
Thanks Stephen and thank you Rem (of Balmoral Air).

EJ Currie. Neutral Bay

Stephen recommended John Montgomery as an installer for our new Braemar gas heating system. John was great - very thorough and professional. We're very happy with the service- and the new system.

“Immediate Help!”

Would like to say Thank You to Stephen & Greg for his Immediate help with our gas ducted heating last week . It was very much appreciated.

Had a brivis gas heating system put in in 2016 by Hi-Tech. Their installers was a brilliant tradesman, really hard working and knew his trade well. Have had no problems with the heating system.
Since then I have had the system checked every year by Hi Tech who have been very professional and reliable. I recently had a question about a restart after the gas to my house was turned off and Hi Tech got straight back to me and solved my problem in a flash over the phone.
Very good company to deal with and good technicians.

Nicky Lowe. Thornleigh NSW

I thank Stephen for promptly attending my call and helping me to fix a programming issue for my heating system especially during the current global situation we are in. I found him to be reliable and patient in addressing the issue over the phone. Highly recommended. Thanks

Massimo Palma,

Dear Stephen

good health to you

Ernest & Rose, Terrigal NSW

Just a brief note to thank you for recommending John Montgomery as an installer for our Braemar ducted heating and cooling system. John was very prompt with his quote and fully explained the installation requirements and associated costs… …John always turned up when he said he would and always put in a good day’s work. he completed the entire installation in quick time and left the work area clean and tidy each day. we could not have been happier with the entire process. We only wish all tradesmen we’ve dealt with were as professional as John.

Paul Wagstaff, Randwick, NSW

Work was carried out promptly and efficiently. Top quality parts were used and I was more than happy with the price. Call these people if you have a problem with your home heating. I have recommended them to friends of mine and they too are very happy. Thank you.

Bevan King, Toronto, NSW

Hi-Tech Gas Services has done two large jobs for me in the past year, from quote through to installation. One was our central heating, the other a new pool heater. Both jobs were done with the utmost professionalism, starting with competitive quotes from John Montgomery. Once we accepted the quotes, the work was done quickly, efficiently and neatly (cleaning up after themselves). I would not hesitate to recommend Hi-Tech Gas Services.

Melanie America, Bellevue Hill, NSW

Stephen was terrific recently in helping us in our search for a gas heater - gives honest advice, very responsive and genuine. No hesitate in recommending Hi Tech Gas Services. Thanks.

To whom it may concern,
We invited John Montgomery to recommend options to install air conditioning in our home. Our invitation was based on advice from a friend that recommended John as an air conditioning engineer who would do an excellent job for us.
John designed a system for us that incorporated much of an existing ducted heating system, upgraded a lot of the ducting for cooling and installed the refrigeration system. That much was excellent but expected. However, he also designed the system to cope with the next generation of our (ageing) heating system, he resolved some issues relating to changes in the Brivis system, personally checked the configurations and commissioned the system. All on budget, all very timely and all exactly as promised.

John will fuss. He will fuss about your requirements; he will want to explain to you what he wants to build, how it should be built and how it should and how it should be configured. He will talk to you about your concerns, your requirements, and your future plans and explain how he will build your plans into his system.

If you want a quick job, with a tradesman who will install a default system and hope it works with minimum input from you, John is not your man. If you want to be confident in the job, confident it will last and cope with later configurations and system requirements, and most of all be confident that he will install what you actually need as distinct from what you think you need John comes with my highest recommendation. He is that old-style engineer who actually cares and I do not think he would install a system that you might think you want, or you have been told you want, if he knows it is not what you actually need.

In short, I’d use John again and I would not bother to seek alternative quotes or alternative advice on systems. I simply would trust John to do another outstanding job.

I first heard about John Montgomery from Stephen and Andy, Andy is a very thorough and reliable serviceman who had been looking after our central heating furnace for some years. Our unit was approaching 20 years old and Andy said something like ” it was already a miracle it is still going”, and that I will soon have to think about replacing it. “if and when you do” said Andy,” get in touch with John Montgomery who is one of the best people in the business when it comes to the selection and installation of a new furnace.” And eventually I did have to get in touch with John, and I immediately realised that this bloke who came along in his work gear to inspect, advise and quote, was a hands-on tradesman who was more genuine than one would expect, knew his business backwards, and talked long and knowingly about how we could improve the efficiency of our ducting, and the best unit for our purposes. Within 48 hours we had a detailed written quote – it was an attractive price compared to my expectations. Work started a few weeks later, the whole job took about a day longer than he had stated in his quote, mainly due to unanticipated underfloor problems, but he never suggested increasing the price for the job. We now have an excellent installation, a more efficient unit, and John has been back a couple of times for some “fine tuning”. This project has been one of the most satisfactory tradesman relationships I have had in 22 years living in our present home, and I would recommend John Montgomery to anyone contemplating a new furnace installation.
