Testimonials

My Ducted Air Conditioning was installed Yesterday. I am writing to let you know that both Yvonne and I are very happy with the installation. The boys were great. They were very professional, very good at their job and had a great work ethic. For us it was like an orchestra. We had delivery of parts 6:30AM, then the electrician turned up to do the switchboard stuff at 7:00AM and then Paul, Grant, Nick and Jordan turned up to do the installation at 7:30AM. They worked very well as a team and made sure that drop sheets were laid to avoid any damage to the carpet and cleaned up before they left as though they were never there. Paul was kind enough to give us a quick rundown on the remote controller. Ed, although I was very pleased with the professionalism of the team, I was not surprised because from day 1 when you came to assess our requirement we were very impressed because you provided us with a solution rather than trying to just sell us a product. So many thanks mate and give our thanks to the rest of the team.

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.

We were so proud to have been part of the renovation rescue on A Current Affair for the Hardaker family. Vanessa and her family were so deserving of this renovation and we were so honoured to have been involved and to have brought the family so much joy. Leisa and I wanted to thank Brad and Julianne for their ongoing commitment and support to buildBITS. We couldn't have achieved what we did for the Hardaker family without you. Brad, you smashed it once again. A complete knock down and house rebuild in just two weeks. Another awesome achievement. And to Julianne, thank you so much for organising the trades and all the buildBITS partners for this incredible home renovation. Such dedication from you both. We also wanted to thank our buildBITS partners who were incredibly generous with their support, time, products and services. And, to the companies we specially connected with for this project and that came on board and provided support, products and services to this beautiful family. It was such a pleasure working with you.

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.

Century Estate 58 - chilled water system in a large (10,000sqm+) A Grade office building designed to achieve 4.5 star energy rating and incorporating a large basement carpark ventilation system. Nexus Norwest - a condenser water system in a large (9,500sqm) strata office building and having to work within restricted building height.

We would like to thank you for the recent installation of our new air conditioning unit. We were most impressed with the team who did the installation... their workmanship... attitude... manners etc. We couldn’t find fault with anything. Last Sunday, we turned the air on for the first time since installation. We were extremely happy with the performance. We have had Crest Air to service our air conditioning before and have always been more than happy with the service and the professional advice given to us by the technicians. We were also impressed by the fact that Brett came to oversee what the boys were doing and was there to answer any questions we may have had. That’s a great service as many companies don’t do any follow up at all. Well done Crest Air. Our sincere thanks to all concerned... we are very happy

I thought it appropriate that I provide feedback on the recent installation of the Actron ESP Plus SRD160C / SRV160E ducted air conditioning system. As you know, we chose Crest Air Conditioning over other quotations due to your professional approach to the quotation process. You were the only sales person to measure every room and calculate the heat load, and your product knowledge was excellent. As you are aware, we paid a premium to have Crest install the system due to the professionalism of the company and our belief that Crest can provide superior backup service in the long term. Your installation crew turned up precisely on time on the day of the installation. They were friendly and professional and worked as a team all day with the installation completed on time with no complications. Please pass my congratulations onto the crew as they were a pleasure to deal with. The Actron ESP Plus SRD160C / SRV160E ducted air conditioning system has surpassed my expectations. In my web based research, there were complaints about the outside unit which have turned out to be completely wrong. The outside unit produces at least half or less noise of the previous 20 year old unit that it replaced. The greatest thing I like about the system is the lack of inside noise, in our old ducted system especially when the system was first turned on, the inside fan noise was intense. The only way to reduce the noise to an acceptable level was to turn all the zones on which meant heating or cooling the whole house, resulting in highly expensive electricity costs. In total contrast, the Actron system is almost silent inside, even with one room turned on; the variable inside fan speed works exceptionally well. My only concern is forgetting the system is turned on when I leave the house as it is so quiet. Congratulations on a job well done, it’s good to see an Australian company like Actron completely outclassing the overseas competition and being professionally supported by Crest Air Conditioning

“Please also pass along my thanks to Edgar and the installation team. The entire process on Tuesday was seamless – the installers were professional, and polite and courteous. And to my absolute amazement, they put absolutely everything back where it belonged – AND cleaned up after themselves perfectly. They were fantastic and I’m extremely happy with my decision to go with Crest. I’ve had a number of tradesman in my house over the past few months doing renovations and other improvements and by far, this was my most satisfactory experience. A big thanks to the entire team for this”
