Should I replace my air conditioning? It’s the question we’re getting more than any other this year.
It comes up in different ways. Our system is getting old — is it worth replacing now or limping through one more summer? We’re listing the house in spring — do we fix the aircon first or leave it for the buyer? We’re renovating — do we put ducted in now or add it later?
Underneath all of it is the same question. Is now the right time to spend money on this, or should we wait?
There’s no single answer. But there is a clear way to think about it. Here’s how we walk our customers through it — without an agenda, and without pretending every situation needs the same solution.
You’re Staying. Your System Is Old. What Now?
Don’t replace what doesn’t need replacing.
Most aircon systems on the Gold Coast last 10 to 15 years. Coastal homes – close to the broadwater, the canals, or the beach – sit at the lower end because salt corrodes the outdoor unit faster.
Here’s the honest framework we use:
Under 8 years and running well. Service it annually and leave it alone. Replacement isn’t a smart use of money right now.
8 to 12 years. You’re in the watch window. Small issues that show up now — weaker airflow, slower start-up, odd noises — are early signals, not emergencies. A proper diagnosis tells you whether it’s a $400 repair that buys you three more years, or the start of a bigger problem. We’ll tell you which one it is, honestly. (How to find the age of your system here.)
12+ years. Plan replacement now, on your terms. Not in January when it gives up under load, lead times stretch to six weeks, and peak-season pricing kicks in. Winter replacement isn’t about beating a deadline — it’s about doing it without the urgency tax.
The trap most homeowners fall into is treating new and needed as the same word. They aren’t. Don’t replace what doesn’t need replacing. Do replace what’s quietly costing you more in repairs and running costs than a new system would.
You’re Selling. Should You Replace Before Listing?
This year, the answer matters more than usual.
Gold Coast buyers are sharper than they were two years ago. Building and pest inspections get used as negotiation tools. An old, noisy, or non-functional air conditioning system is one of the most common items that comes back in a report — and one of the easiest for a buyer to use to pull thousands off your asking price.
Three things buyers (and their inspectors) actually check:
- Does it run? They turn it on, walk around, see if rooms reach temperature.
- How old is it? Looking for the manufacture date on the outdoor unit badge.
- What’s the condition of the outdoor unit? Rust, corrosion, weathered casings — all visible signs of a system on borrowed time.
Here’s our honest take on the decision:
If the system is under 10 years and working — leave it. Pre-listing servicing (around $250–$350) covers it. Don’t over-invest in a fixture buyers won’t pay extra for.
If the system is over 12 years, or visibly aged — strongly consider replacing. Not because new aircon adds dollar-for-dollar to the sale price, but because not replacing it gives buyers leverage to negotiate $5,000 to $15,000 off the price, and to delay or condition the sale. A $10,000 ducted replacement that protects a $50,000 negotiation is good economics.
If the system is broken or in obvious disrepair — replace it or disclose it. Don’t try to hide it. Modern buyers test it. The deal that falls through at the final inspection is the most expensive outcome of all.
You’re Renovating. Build It In Now or Add Later?
Now is genuinely cheaper. This isn’t sales talk — it’s geometry.
Installing ducted air conditioning during a renovation is significantly cheaper than retrofitting later. The walls are already open. The ceilings are accessible. There’s no patching, repainting, or working around a finished home.
A rough comparison from the work we do:
- Ducted during renovation: standard install
- Ducted retrofitted later: typically 25% to 40% more, plus the disruption of having tradespeople in a finished home
If you’re planning to install ducted within the next 5 years anyway, doing it during the current renovation is almost always the better financial decision — even if the upfront cost feels heavier right now.
One thing builders won’t always tell you: the ducted decision needs to happen before the ceiling goes up. Once the plasterboard is on, the math gets worse fast. If you’re mid-build right now and ducted is on the table, this is the conversation to have this week.
Should I Replace My Air Conditioning? A Simple Way to Decide
We use a question with every customer who’s weighing this up:
“What does it cost you to spend on this now?” And then — “What does it cost you not to?”
For some homeowners, the answer is clear. The system is reliable, you’re staying, you don’t need to spend. For others, the cost of not spending — a failed system in summer, a buyer renegotiation, a doubled retrofit price — is far higher than the cost of acting now.
There’s no virtue in spending money you don’t need to. There’s also no virtue in pretending an old system on its last summer is fine. We’ll tell you which one you’ve got.
Frequently Asked Questions
How do I know if my air conditioner needs replacing or just repairs?
Age, history of repairs, running cost, and the condition of the outdoor unit. A reliable system under 8 years is worth repairing. A system over 12 years with multiple recent repairs usually isn’t. The honest answer comes from a proper diagnosis, not a hunch.
Does new air conditioning add value when selling a Gold Coast home?
Not dollar-for-dollar — but it removes one of the most common buyer-negotiation tools. The real value isn’t what it adds to the sale price. It’s what it protects you from losing.
Is winter a good time to replace air conditioning?
Yes. Technician availability is better, lead times for equipment are normal, and prices haven’t moved into peak-season territory. Replacing in winter means doing it on your timeline, not the system’s.
Should I install ducted air conditioning during my renovation or after?
Almost always during. Retrofitting into a finished home typically costs 25% to 40% more and involves significantly more disruption. If ducted is anywhere on your 5-year plan, doing it during the current renovation is usually the better financial decision.
