The team were awesome. Quoted for the job on Thursday morning and arrived 7am on Friday morning to do the install.The guys sorted out all of my issues with the previous installation that was done 20 years ago - bad wiring, unit positioned so they didn't drain properly, all sorted.They took everything away, left both rooms and outside area where they were working spotless, couldn't be happier with the quality of the work.

After Crest installed 2 split A/C units 10 years ago to our complete and ongoing satisfaction, we now needed a new split A/C supply and installation, relocation of a unit, and the removal of 2 older units not originally installed by Crest. Once again, Crest completed the work to our total satisfaction. My original online enquiry was answered within the hour, a representative was in our house the next day, and all the work was completed by the end of that week. The technicians were polite, efficient, very helpful, and cleaned up all work areas perfectly. Everyone we had engaged with was totally professional, efficient and pleasant. Highly recommend.

Had no end of trouble trying to find a company to advise and supply multi head air-conditioning that was hidden from public view due to townhouse strata rules. But finally I came across Crest who were just the best from start to finish. Ed and his team were excellent in all areas of the purchase process: punctuality, good value quotation, recommending Mitsubishi unit (btw Mitsubishi were the top rated company in the recent Choice magazine test of air conditioning units) firm installation time and quality of installation workmanship .And guess what ? The installation team arrived exactly on time, were courteous and cleaned up after completion. I was very surprised by Crest's professionalism throughout especially the installers who were a happy knowledge team. The Mitsubishi system they installed is amazing; it is also very quiet. My family is very impressed with the end result of this project and therefore so am I 😊

I contacted Bobbi-Jane to request assistance with my air conditioning vent maintenance. Bobbi organised the same day service and Mick attended as scheduled to provide the maintenance needed. I really appreciated the personal care given when Bobbi realised we had someone at home recuperating and made sure we could use our air conditioning to its full capacity as soon as possible.

These guys know their business and I'm very happy that I chose Crest. They sized the system perfectly and advised me to opt for a bigger unit and I'm glad I listened. They gave me the best price in the market. The installation team were equally good, came in as promised, were meticulous and completed the job, cleaned up any waste before leaving. To get an early installation date was a challenge as it was right in the middle of summer but it was well worth the wait. Overall a very pleasant experience.

From the standpoint of a supplier I can't recommend Crest enough. They have always been courteous and prompt in any dealings with us. They are perceived as a major player in mechanical and HVAC, and I can see why.

Taylor Construction Group would like to take this opportunity to thank everyone involved from your company for their efforts in completing the Law Court project. We appreciate the hard work put in by all and understand that if it wasn’t for the collective effort, we wouldn’t have achieved such a fantastic result for the client, which allowed them to open each stage on their desired date. We have enjoyed working with you on this project and I hope we can continue the good working relationship we have formed on any projects that we may work on in the future.

Hi Andrew, as you may be aware, we have recently completed the project at Waterloo Rd. Its pleasing to have Goodman respond so positively to the final product that we delivered. In particular, that we delivered a quality product that finished on time and within budget. As a Principal Contractor, we understand that we are only as good as our Subcontractors. Its only with the help of skilled and collaborative businesses like yours that we are able to deliver projects in the manner that we do. On behalf of Lipman I want to thank you and your team for their effort on this project. I hope to see you on the next one.

Most of us would have to admit that we’ve had our share of mediocre service from companies in the past. However, some companies are starting to "get it". They realise that in today's global marketplace, consumers have a greater number of choices than ever, therefore they are providing better buying experiences for customers to inspire loyalty, rather than depending on fancy schmancy ad campaigns. So on behalf of Virgin Active Norwest I just wanted to pass on a big thanks to our air conditioning service provider CREST. You have been instrumental in providing quality service at all times and as operations manager for this proud health club, I could not ask for more from your entire team, whether it is your service technician Prav being pro-active in all his work or the service team and yourself responding to all of our issues in a timely problem free manor. Thank you for your support, it is greatly appreciated.
