Frequently asked questions

Here are some common questions about our electrical and air conditioning services. For more complex questions, please contact your us for a chat.

A commercial electrician is trained and experienced in completing commercial electrical work, such as the electrical work you’d find in factories, shopping centres, hospitals, schools and offices. Commercial electrical work is carried out in line with a different set of regulations to those used for residential work. The wiring designs, appliances and wiring materials are significantly different to residential options.

Yes! As a company, O'Brien is accredited by CM3. In addition, each member of our team has the relevant certification to work on commercial projects.

If you’ve got an electrical emergency (for example, an industrial fridge that’s failed, or a hazardous electrical issue), we can usually get it fixed for you in a few hours. This reduces the amount of time your operation is out of action.

For scheduled work, we can arrange to complete what’s needed when your production is at its lowest. If required, we can work out of hours in order to get the necessary tasks completed at the same time as keeping disruption to a minimum. When you book the work, let us know your timescales and we will do our utmost to work around them.

O'Brien offers a high-quality, affordable solution to all your commercial electrical needs.

How much does electrical work cost?

The cost of electrical services depends on several factors, including the type of service, materials required, and the complexity of the job. O’Brien Electrical & Air Conditioning Thomastown always adheres to Australian industry regulations and safety standards, ensuring all work is performed to a high-quality benchmark by licensed professionals.

Whether it’s repairs, maintenance, or installations, we aim to provide the right solution for your property — ensuring the safety and comfort of your family, business, or tenants.
