Tips to Find the Right Location for Your AC Unit

Ready to surf the tide of confusion and smack it with some wisdom on air conditioning installations? Prepare your cup of tea, we're going to have a chat on how to find the best location for your AC unit. It might look like a piece of cake at first glance, but oh my, do we have some chill information coming for you!

Know Your AC

When trying to deciding on how to get the most our of your home air-conditioning it's essential to take note of the type of system you have. Essentially, there are:

Split System Air Conditioners

Split System Air Conditioners

Split System ACs consisting of a buddy team of an indoor unit and an outdoor unit are a popular choice amongst many homeowners. But choosing their perfect spot? That's a bit like solving a happy puzzle.

You see, the indoor unit loves high places, preferably on top of a wall that allows for adequate air distribution. It's not a fan of obstacles like furniture or curtains. What about the outdoor unit? Well, that guy enjoys fresh air and shade, needs a solid surface to rest on, and prefers some peace and quiet away from your living areas to minimise noise.

Don't forget, though, that these units need to be close enough to connect via refrigerant lines, electrical wiring, and a condensate drain pipe. So, balance is key!

Ducted Air Conditioning Systems

Now, if your home is blessed with a ducted system, things change a bit. These systems, often found on your roof or hiding away under your floor, need their location thoroughly planned to guarantee optimal cooling.

The main principle is about allowing the cooled air to travel through the ductwork and into your rooms in the most efficient way possible. Therefore, the location of your ducted AC system will heavily depend on the ductwork layout of your house.

Efficiency is the name of the game here. You want minimal twists and turns, and shorter duct runs where possible. And remember, stealthy as they may be, these systems need maintenance too, so consider access when planning their location.

Portable Air Conditioners

Ah, those flexible Portable ACs, freedom-loving as a kangaroo! These units like to stay close to windows for venting and near power outlets. They can cool individual rooms quite effectively, relying on you to decide where their services are most needed at any given moment.

While their mobility is great, they're not a fan of feeling cramped. Placing them in a room with some space allows excellent air circulation. Although their cooling capacity can't compete with a split system or ducted system, they are an easy plug-and-play solution for targeted cooling.

Anatomy of the Perfect AC Location


Welcome to the anatomy class you never thought you'd need. The ideal location for your AC unit is not some mythical unicorn. It's pretty straightforward:

Room Size and AC Performance

It's no riddle that the size of the room is a crucial factor to consider. Make sure your air conditioner's cooling capacity matches the room's size. Also, place your indoor unit at a location that allows for even distribution of cool air.


Sure, we all love some good Australian sunshine, but your AC outdoor unit? Not so much. It loves basking in the shade. Placing the outdoor unit in a shaded area can enhance its efficiency, and guess what? It saves you some money on bills.

Wall Strength

Let's not forget, that these units aren't featherweight. Choose a wall that can bear the load of the AC, while also considering noise transmission.

Noise and Vibration Levels

Who loves the noise of a roaring AC in their home? Probably no one. Thus, selecting a quieter corner of your property, away from bedrooms, for the outdoor unit is the way to go.

Respect Your Neighbours

We want to make sure our cooling comfort doesn't become a nuisance for the folks next door. Consideration should be given to their living spaces and outdoor areas when deciding on the placement of the outdoor unit.

Ease of Access

Routine maintenance, filter cleaning, and repairs by professional technicians are unavoidable. So, make sure that your AC unit is easily accessible, with enough room for them to work their magic.

Water Draining

Bet you didn't think of this one! The condensate produced by your AC needs to drain away properly; choose a spot that won't cause damp walls or puddles.

The Final Touch – Aesthetics

Functionality might take the limelight, but let's give some credit to the aesthetics as well. Find a spot that doesn't screw up the overall visual appeal of your property. After all, who wants an AC unit to be the photobomber in their idyllic backyard setting?

What About the AC Regulations?

You may be wondering if you can just plop your AC unit wherever your heart desires. The reality? Government regulations and guidelines provide specific mandates on where your precious cooling kit can be installed.

Things like clearance from gas regulators, combustible materials, public spaces, the boundaries of your property, and neighbouring properties all need to be considered. There are even rules about how high the outdoor unit should be from the ground!

Wrapping Up

May you enjoy many moments of cool tranquillity in your beautiful, energy-efficient home. If you ever find yourself needing further guidance on air conditioning systems just know that the pros always here, ready with more handy insights and solutions to help you make the best decisions for you and your home.
