Tips & Advice

What to consider before installing air conditioning in your home

We all know the feeling when the ceiling fan just isn’t cutting it anymore!

This Australian summer is expected to be the hottest on record, so our homes will be heating up.

Now is the perfect time to install an air conditioning system to keep your family cool and comfortable for the summer months ahead. But where do you start?

Avoid making an impulse buy. Learn about what different air-conditioner models and installations, then get in touch with our team to plan where your new system will fit, inside and outside.

Curran’s hot tips for cool air

Our team of expert installers have compiled some handy tips with all the facts you need to know about installing air conditioning in your home.

What type of air conditioning is best for my home?

Decide whether you want a ducted air conditioning system or a split system. The choice depends on your budget, the size of your home, and your cooling needs.

If possible, consider a zoning system that allows you to cool specific areas of your home at different times. This can help save energy and improve comfort.

Other factors to consider include your home’s roof or floor space access for ducting and outside placement of units.

Fujitisu has a handy online tool to help you consider the best solution for your individual needs. You can access that here.

How does room size relate to air conditioner capacity?

Consider your home’s layout and, in particular, the dimensions of the room or rooms you wish to cool (or heat in the winter months). That’s because an undersized unit will struggle to cool the space, while an oversized one will cycle on and off frequently, wasting energy.

Think about any future home renovations or expansions that might affect your cooling needs. Plan for potential changes in your home’s layout.

Where do I locate the air conditioner?

The orientation of the chosen room/s will affect the air conditioner’s location, especially if you get sunlight directly through a window in the morning or afternoon.

Split system air conditioners have an indoor unit, often located near a window, plus a unit outside, so you need to assess how that will affect your indoor and outdoor spaces.

Are air conditioners useful for heating the home?

Air conditioners function really well as heaters and are a safer option if you have children or pets running through the home. Air conditioners can even be the more economical heating option. A recent Choice article found reverse-cycle air conditioners to be “one of the most efficient and cost-effective ways to heat individual rooms and large living spaces, beating electric and gas heaters on running costs”.

Will smart features help?

Modern air conditioners often have smart features like Wi-Fi connectivity and programmable thermostats. These can enhance convenience and energy savings.

What about maintenance and warranties?

Consider the ease of maintenance and access for cleaning or repairs on your air conditioning system. Regular maintenance is essential to keep your system running efficiently. It will benefit from yearly servicing, and may need repairs over its lifespan. It’s best to be proactive with servicing and avoid problems arising with you AC unit.

Check the warranty offered with the unit and ensure you understand the terms and conditions. Regular maintenance might be required to maintain warranty coverage.

What do installation costs cover?

Curran professionals will supply up front pricing so you will know the full installation costs before proceeding.

Note that you will need to hire a professional because Australian regulations require both electrical and refrigeration licensing to legally install an air conditioner.

What local regulations and permits are needed?

Check local building codes and regulations regarding HVAC installations. You may need permits for installation, and there may be specific requirements you must follow. Curran’s HVAC technicians are fully qualified to handle all of your air conditioning needs and will ensure your air conditioner installation meets required standards.

What duct work is needed?

A new ducted air conditioning system will require a plan for the ductwork throughout the home.

If replacing an older ducted system, ensure that your ductwork is in good condition and properly sealed. Leaky or poorly insulated ducts can reduce efficiency.

Will the air quality improve?

Some systems come with built-in air purifiers or filters. If you have concerns about air quality, this may be an important feature to consider.

Contact our team

Remember that consulting with a qualified HVAC professional is essential for making the right decision. and proper installation is crucial to the system’s performance.

Professionals can perform a load calculation to determine the ideal size and type of system for your home and provide guidance on installation and maintenance.

By hiring a company like Curran, your qualified air conditioning technician can also carry out associated electrical work, such as adding a dedicated circuit to the switchboard.

Thinking of the future, start out with a trusted company that will stay around, so you can keep your cool. Get in touch today.

Here’s a handy checklist that will help you in your decision making:

Your priorities

  • Are running costs your main problem?

Check the Zoned Energy Rating Label on new models.

  • Is heating a big priority?

Look for reverse cycle models.

  • Is air purification a big priority?

Look for built-in purifiers.

  • Do you only want air cooled?

We can offer the perfect solution for your needs; speak to our technicians, who will advise you on the best solution.


  • Is the room poorly insulated?

Improving insulation to reduce air leakage will save air conditioner running costs.

  • What direction do your windows face?

Avoid locating in path of direct morning or afternoon sun.


  • Are you renting?

Speak with your landlord to see whether they will install air conditioning or whether they will give you permission to do so.

  • Are you in an apartment?

Consider the impact of the system’s noise levels on your neighbours.

  • Are you in an office?

Look for a system with a zoning function.

  • Is it for your holiday home?

Look for programming timers and smart features to ensure the aircon doesn’t stay on accidentally.

Curran were out within an hour of my call. I was fully advised by the person on the end of the phone of their procedures and they communicated with me by text and email during my wait. The technician gave me 25 mins notice of his arrival. He advised me what he would be doing, the price, and when he was about to turn the power off. Fixed the problem in 20 mins. I was very impressed with their customer service.

I found the guys at Curran Electrical and Plumbing to be great, they were open really friendly and helpful. They did the job on time with no mess. I also found them to be honest. I thought I had to replace two lights in the bathroom however while installing the new ones we found another switch so I did not need them replaced after all and the quote was adjusted to reflect this.

Curran Plumbing & Electrical recently installed a new pump on my rainwater tank. I am very pleased with their work and also that they were able to do it within a few days of getting their quote. I also appreciated that when the quote was done that a video was taken of what needed to be done, so that whoever did the work knew what needed to be done.

Sam was bang on time and fixed our septic issue very quickly. He also sent a camera up the pipes to ensure everything else was fine before leaving. We've enjoyed our ongoing relationship with Curran after they did some major works for us last year and our membership is well worth it.

From the first phone call Curran plumbing services were professional, showed up on time for scheduled quote , then me updated when the job was going to be completed . On the day of install all of the staff were well trained , well spoken and installed my new instantaneous gas hot water system like they were installing it in their own home . The quality in detail to make sure I was satisfied didn’t go unnoticed. At the end of the day I feel like I have gained a plumber for life . 100% recommend.
