Common problem
Air Conditioner Frozen in Andrews Farm
Ice on your air conditioner in Andrews Farm is not the system overachieving. A frozen coil means airflow or refrigerant has gone wrong, and the longer it runs iced up, the more damage it does.
Why Your Aircon Freezes Up on a Hot Andrews Farm Afternoon
Andrews Farm homes run their cooling hard through dry Adelaide summers, and a system that ices over is telling you something is restricting it. The good news is that most causes are straightforward to diagnose and fix.
What Makes an Aircon System Ice Over
Several faults produce the same symptom: a coil covered in ice and a unit barely breathing. Here they are, cheapest first.
Dirty air filters
Low refrigerant charge
Blocked airflow outside
Faulty fan or motor
How it works
Cooling Checks You Can Try First
Two checks cost nothing and sometimes solve the problem outright:
- 1
Step 1
Check the filter. If it is grey and matted, wash or replace it and give the unit a few hours with the ice gone before restarting.
- 2
Step 2
Check the outdoor unit. Clear away leaf litter and make sure nothing is blocking the airflow around it.
If the ice comes straight back after that, stop. Running a frozen system risks the compressor, and that is the expensive component.
When a Frozen Split System Needs a Pro
Call a technician if any of these apply:
- The ice returns within a day of a clean filter and clear airflow
- You can hear hissing near the pipes, which points to a refrigerant leak
- The unit trips power or the fan has stopped turning
- The coil ices even on mild days when the system is barely working
A refrigerant leak is not a do-it-yourself job. It needs the leak located, repaired and the system re-gassed by a licensed tech. If the frozen unit is also blowing warm air, our page on an air conditioner blowing warm air covers the overlap.
How it works
How We Fix a Frozen Air Conditioner
We diagnose before we quote, so you pay for the real fault and nothing else.
- 1
Thaw and inspect
We let the coil defrost fully, because ice hides the evidence and a proper inspection needs the coil bare.
- 2
Test airflow
Filter, blower, duct and outdoor unit, in that order, because airflow faults are the most common cause.
- 3
Check refrigerant
We test pressures and trace any leak before adding gas, since topping up a leaky system just books you a second callout.
- 4
Fixed price quote
You get the price in writing before any repair starts, under our Fixed Upfront Pricing promise.
If the compressor has been damaged by running frozen, we will say so plainly and price a replacement through our air conditioning replacement service rather than selling you a doomed repair. Every workmanship fix is backed by our Lifetime Labour Warranty.
Questions
Frozen Aircon Questions From Andrews Farm Homes
Why is my air conditioner icing up even in summer?
A dirty filter or low refrigerant drops the coil below freezing, so moisture from the air turns to ice on the coil even while the sun bakes the roof above it.
Can I just run the unit to melt the ice?
Running it flat out risks the compressor, so switch the system off at the wall and let the ice melt naturally, using fan-only mode if the manual allows it.
How long does it take to fix a frozen system?
A simple airflow fix can be done in one visit, while a refrigerant leak needs the leak found and repaired first, so we quote the real job after diagnosis.
Will a frozen coil damage the system?
Yes, ice stops heat transfer across the coil and forces the compressor to run against a block of ice, which is how an affordable repair becomes a full replacement.
