Crest Power carries out projects in both commercial and industrial type premises. We provide a number of domestic and commercial electrical services, with most of them listed below. If you require electrical work that’s not listed below, please call us and we will be able to assist you.


From small or large installations, Crest Power can undertake many types of projects from the design stage all the way through to final inspection and testing of the installation, issuing all relevant certificates as required.


Due to the continued requirement for ongoing safety and production, Crest Power can provide a service or maintenance of existing installations.

Security Systems

Our engineers can install security systems to meet client requirements, as well as PIR or night/day external floodlighting system.

Inspection and Testing

We can provide inspection and testing for commercial and industrial premises to meet legal regulations. Our fully qualified and dedicated team will provide this service with minimal disruption to the client.

Home Theatre Installations

Home theatre projectors are highly recommended video projection solutions for any modern, compact or smaller home theatre application. Today’s home theatre projectors are equipped with the latest DLP chips and offer super clear image projection, contrast ratios and brightness.
We recommend projectors with a native 16:9 widescreen resolution for home theatre applications, especially when mainly used for movie playback.

Test and Tag

A full and competitive service can be provided to carry out Test and Tag to all plan and equipment to meet the requirements of The Electrical Safety Act 2002 and of the client.
It is the responsibility of an employer to ensure that specified electrical equipment must be regularly and properly inspected, tested and tagged ‘safe’. Section 83 of the Electrical Safety Regulation 2002 provides a definition of specified electrical equipment.

Only a person deemed competent can do this. The Electrical Safety Regulation 2002 defines a competent person as someone who has acquired, through training, qualifications, experience or a combination of these, the knowledge and skill enabling the person to inspect and test electrical equipment.

The employer or self-employed person is responsible for determining that the person who carries out inspection, testing and tagging of electrical equipment has the required competencies.

Commercial Screen Applications

Whilst the 16:9 widescreen resolution is good quality viewing, depending on the application, i.e. if you use the projector in a bar for sports broadcasts, music DVD’s etc., a projector with a native 4:3 full screen resolution might be a better option. Alternatively, you may also choose a model that can support both formats.

Projector and Screen Installations – Conference Room

Conference/Boardroom applications can greatly improve the quality of the meeting and/or training session.

We focus on achieving the best solution for your establishment to meet both your needs and your budget. To ensure that your exact requirements are met, we will send out an expert projector installer to carry out a free site survey and evaluate any existing equipment that needs to be integrated into the final install.

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.

Engineering Partners have had a long and successful working relationship with Crest Air Conditioning. This relationship began in 1989 with the construction of a new 12 storey office building in Clarence Street Sydney. Crest Air Conditioning applied themselves very well throughout this project much to the client's satisfaction and to our knowledge still maintain the building to this day. Since that time we have been continually impressed with Crest Air Conditioning's professional attitude and dedication to providing quality air conditioning and mechanical services across a broad range of projects. We have been proud of our success with Crest Air Conditioning to this day. Some of the many projects worked on include: Data Centre - involving a major chilled water system Citywest Office Buildings, Pyrmont 55 Clarence Street, Sydney Parramatta Road, Strathfield Cancer Council 210 Clarence Street, Sydney Waverley College - Performing Arts Centre Blakehurst Aged Care Centre Engineering Partners have no hesitation in recommending Crest Air Conditioning to any prospective client.
