Before you buy

Which size do I actually need?

Buying an aircon? Easy.

Until old mate says:

“Just get the biggest one.”

Right.

Because apparently your bedroom now needs enough cooling for a Woolies.

Go too big

You can spend hundreds more buying it...

Then more again running something the room never needed.

Cold blast.
Stops.
Starts again.
Cold blast.

“Beautiful. More power.”

Yeah. Except you paid more... and the room still might not feel right.

↓

“Alright then. I’ll save a few bucks and go smaller.”

Also brilliant.

Until Sydney hits 35 degrees...

The sun is smashing through the windows...

The aircon has been running flat out for six hours...

And you are standing underneath it like:

“Is this thing actually on?”

You saved a couple hundred bucks.

Congratulations.

Now you get to be hot for the next eight summers.

The funny part? Two rooms can be the exact same size... and still need completely different aircons.

Same size room. Different answer.

Because the room is only part of the story.

Before anyone confidently throws a kW number at you, there are a few things worth looking at.

What actually changes the answer?

Windows
Big glass and hot afternoon sun can change how much heat gets into the room.
Sun exposure
A shaded room is not doing the same job as a room getting smashed by western sun.
Insulation
Better insulation helps keep the comfort you already paid to create.
Ceiling height
More air above your head means more air the system has to control.
Layout
A closed bedroom and an open-plan living area are two very different jobs.
How many people use the room
One person in a bedroom is not the same heat load as the whole family in the living room.
So maybe...

“Biggest one, mate” isn’t a sizing calculation.

You do not need to become an air-conditioning engineer before buying one.

You just want the recommendation to make sense for your home.

1

Do not guess from square metres alone.

Room size is a good starting point. It is not the whole answer.

A room with small shaded windows can behave very differently to the same-size room with a giant glass door in full afternoon sun.

Same floor area. Different job.

2

Do not copy your mate’s aircon.

Your brother might love his 7kW.

Your neighbour might swear by a 5kW.

Good for them.

You are cooling your house, not theirs.

3

Do not “go bigger just to be safe”.

If the bigger unit genuinely suits the room, great.

But if nobody can explain why you need the extra capacity, why are you paying extra for it?

4

Do not go too small just to win on price.

Saving a little upfront feels clever right up until the first proper Sydney heatwave.

Cheap is not cheap if the room still feels hot.

5

If you are not sure, ask one simple question.

“Why this size?”

A good recommendation should be easy to explain using your room, windows, sun, insulation, ceiling height and layout.

If the answer is basically “because bigger is better”... you might want another answer.

Now you know what to look for

Here is how our installed price is structured.

Rather than asking you to take “fully installed” on faith, for a qualifying standard SplitsPro installation the advertised installed price already includes the normal parts of the job below.

Up to 3m pipeworkRefrigeration pipework for the standard installation is included up to 3 metres.
Up to 20m electrical runA standard electrical run is included up to 20 metres.
Installation labourThe standard install labour is part of the advertised installed price.
Testing & handoverWe finish the installation, test the system and hand it over ready to use.

And if your home is not a standard install? We tell you first. Longer pipe runs, switchboard upgrades, difficult access, asbestos-related work and other non-standard requirements are priced before proceeding. No fear-mongering. No pretending every home is the same.

Why be this upfront?

Because a happy customer is worth more than one bigger sale.

If we size the system properly, explain the price before we start and leave you happy with the job, you are more likely to recommend us, leave a good review and call us again.

Trust should start before we pick up a tool.

We do not expect you to trust us because we say “quality work”. We would rather make the quote easy to understand, explain the choices, show you finished work and stand behind the installation.

✓ Extras explained before work starts
✓ No pressure to buy a bigger unit
✓ Workmanship guarantee
✓ Eligible standard installs within 7 days
Now compare for yourself

Not every cheaper quote is bad. Just make sure you know what you are buying.

If you already know roughly what size you need, you can now compare our current Rinnai and Daikin supplied-and-installed prices using the same checks above.

*“No More To Pay” applies to qualifying standard installations. Non-standard requirements are explained and quoted before proceeding. Installation-time guarantees are subject to the offer conditions shown on the current installed-specials page.
