Here are two questions we commonly get asked about air conditioning installation –

How do you know what air conditioner is best for my home? 

Customers often ask what size and type of air conditioner suits their homes.  To answer, we must calculate a combination of factors to get the right system for your space.  These include:

  • room size 
  • if your home is insulated 
  • how many windows
  • the number of people in your home 
  • the design of your rooms, be it enclosed or open plan

Considering all these factors, we can predict what air conditioner you will need for any area and the best place to position it for optimum performance.

Why does air conditioner size matter?  

You get the most from your air conditioner when it is the best size for the room.  Essentially it comes down to efficiency.  Bigger isn’t always better as it may not operate at its optimum, and if too small, it can work too hard. Therefore, if you choose the wrong-sized air conditioner, you will pay more for electricity.  The right-sized air conditioner will slowly cool or heat your home in cycles.  Matching these cycles to your home conditions to get the right temperature gives you the most efficient system for your home.  In other words, no unnecessarily high electricity bills.

Thank you for my switchboard upgrade, it was achieved with no fuss and no mess. Dennis supplied the knowledge and materials to back my queries regarding protection for my computers. Highly recommended.

Sarah McCarthy

Dennis is an excellent service provider. He arrived on time to an urgent job that I had as a tenant and carried out all the jobs quickly and efficiently and left very little for me to clean up. Will definitely recommend 73 Electrical to others.

We were very happy that we chose 73 Electrical for our electrical project. From the first phone call to Dennis we received a friendly and courteous response.

73 Electrical were prompt, professional and friendly. Our power went out and we called Dennis immediately, he understood the urgency to get our power up and running. What a service!.


I cannot recommend Dennis enough!! We had all our internal lights replaced by Dennis, half of which are on dimmers. He was fast, efficient, and beat all other quotes we received by a landslide!!! Dennis even got us a tradie discount at the local electrical wholesalers. The work was neat and tidy with high quality workmanship. Thanks Dennis!! You will be our preferred electrician for all future work.

Over the last three years Dennis from 73 Electrical has been my electrician. I have to say he does an excellent job and goes above and beyond on all my jobs sites. He has done little jobs to 350m^2 new build projects for me and does a great job every time.
