Questions to Ask Before Your AC Installation Day

February 6, 2026

Picking an air conditioner is only half the decision.

Choosing the person who installs it can make just as much difference. It is not just about getting the job done, it is about making sure the job is done right. When you speak with local AC installers ahead of time, you get the chance to ask the questions that help avoid problems later.


As February starts, daytime highs still hover at summer levels across Canberra. That means most homes are still depending on cooling almost every day. If you are getting an air con installed now, or planning one soon, it helps to be prepared. Knowing what questions to ask before installation day makes the whole process smoother, start to finish.


What Experience Do You Have With Homes Like Mine?
Every house is different. That is why asking about the installer's experience with similar builds matters. A solid air con setup depends on how well the system fits your space.


• Ask if they have worked with homes around the same age and layout as yours. If you live in a 70s brick veneer or a newly built duplex, it matters.

• Check whether they have handled your property type before. Apartments, townhouses, and freestanding homes each bring their own quirks.

• Wall material is practical stuff, but easy to miss. Installing on double brick is not the same as mounting on plasterboard or concrete.


A technician who has worked on builds like yours before will likely have fewer surprises once the drill comes out.


What Size and Type of Unit Do You Recommend, and Why?
Cooling a home well is never a one-size-fits-all sort of thing. The right air conditioner is not chosen just based on square metres alone. A proper installer will factor in both the space and the way your home holds or loses heat.


• Ask what calculations they use for picking the right size. It should not just be guesswork.

• Make sure they are considering what insulation you have, how high your ceilings are, and where the sun hits during the day.

• Ask why they are recommending a particular model or brand. If they are confident, they will be able to explain why it suits your home instead of just listing features.


This part helps make sure the system you install actually keeps your space comfortable without using more power than necessary.


Where Will the Indoor and Outdoor Units Go?
Placement makes a massive impact, both on how well your system works and what it takes to look after it over time.


• Talk with the installer about airflow. For most homes, the indoor unit should be high on the wall with no furniture blocking it.

• Ask if there is a way to avoid blasting cold air straight at beds or sitting areas. That can be uncomfortable and wasteful.

• Outside, see if the unit will be protected from the sun and free of narrow passageways. A shaded area with open airflow works best and makes maintenance easier.


Poor placement means uneven cooling or extra noise. Planning ahead prevents problems later.


Do You Handle Council Rules or Approvals If Needed?
In some parts of Canberra, installing an air conditioner is not as simple as cutting a hole and bolting on a unit. You will want to check if any approvals are needed based on your building rules or strata agreements.


• Confirm if they have done installs that needed ACT planning permission, especially in heritage areas.

• Ask about paperwork. Will they deal with strata committees or help with forms if you need to sign anything official?

• If it is your job to get approval, you will want to know early rather than hold up the install.


These things do not always apply, but when they do, they can delay the work if nobody brings it up.


What Should I Expect on Installation Day?
No one wants surprises while work is happening in their home, especially in the middle of summer. Knowing what to expect makes the day easier.


• Ask how early the installers will arrive and how long they expect the job to take.

• Will rooms need to be cleared or furniture moved? Knowing this ahead of time means less fuss when they show up.

• Confirm if the installation includes full testing and a walkthrough of how to use the remote or wall panel settings.


A good installer does more than plug it in and leave. They will check that it works the way it should before packing up.
