At Chilko AIR, we get asked this all the time:
“My split system isn’t working properly—should I repair it or just replace it?”
If you’re reading this, you’ve probably had the same thought. Maybe your air con is blowing warm air, making strange noises, or just isn’t keeping up like it used to.
And the truth is—there’s no one-size-fits-all answer.
So, let’s break it down and give you everything you need to make the right call for your home, your comfort, and your wallet.
The 5 Key Factors That Determine Whether to Repair or Replace a Split System
1. Age of Your AC Unit
The average split system lasts about 10 to 15 years according to Daiken.
If your system is over 10 years old and you’re facing a major repair (like a failed compressor or faulty circuit board), it might make more sense to put that money toward a new unit.
Our rule of thumb:
If the repair costs more than 30–40% of the cost of a new system AND your unit is over 10 years old, replacement is often the smarter move.
2. Cost of Repairs vs. Replacement
Small issues like a clogged filter, low refrigerant, or a capacitor replacement? Definitely repair-worthy.
But if you’re facing a $1,200+ bill for major parts and labour, it’s time to compare it against the cost of a new, energy-efficient unit that comes with a fresh warranty.
3. Energy Efficiency
Older split systems tend to be less efficient—especially if they haven’t been serviced regularly.
If your energy bills have been creeping up, it might not just be your electricity provider. A new split system with modern inverter technology could cut your cooling costs by 25–40% or more.
4. Frequency of Repairs
Ask yourself:
“How many times have I had this unit repaired in the past 2–3 years?”
If it feels like you’re constantly calling someone out (even if it’s us), your system is probably costing you more than it’s worth.
5. Comfort Level
Are you constantly fiddling with the remote trying to get the temperature “just right”?
Is one room freezing while the other’s sweltering?
If your system isn’t keeping your home consistently comfortable—especially during those humid Nowra summers—then replacement might be the more satisfying (and stress-free) choice.
When It Makes Sense to Repair Your Split System
Let’s be real—not every fault means you need a new system.
You should consider repairing if:
- Your unit is under 10 years old
- The issue is minor (fan motor, capacitor, thermostat)
- Your energy bills are still reasonable
- You haven’t had frequent problems in the past
At Chilko AIR, we’ll always start with the most affordable, practical fix first—because that’s what we’d want someone to do for us.
When It’s Better to Replace Your Split System
Consider replacing your split system if:
- The unit is 10+ years old
- Repairs are costly or becoming frequent
- Your energy bills are on the rise
- Your home isn’t cooling or heating evenly
You want the latest smart features (like app control, zoning, or smart sensors)
