Common problem
Air Conditioner Frozen in Mile End
An air conditioner frozen over in Mile End usually points to airflow or refrigerant trouble, and Mile End Air Conditioning finds the cause and quotes a fixed price before any work begins.

The Local Aircon Crew That Mile End Calls When Coils Ice Up
Ice on an indoor unit is a fault, not a quirk. We are a family-owned crew with ten years across Greater Adelaide, we work Mile End and the inner west every week, and we carry the parts and the testing gear to trace the cause properly.
In detail
Why Your Cooling System Ices Over
The coil inside your unit is meant to sit just above freezing while warm room air flows across it. When that airflow drops or the gas charge runs low, the coil surface falls below zero.
Every bit of moisture in the room air then freezes onto it. Left running, the ice builds into a solid block, airflow stops completely and the system cools nothing at all.
The expensive part. The compressor keeps pumping against a blocked coil, and that is how a small fault becomes an expensive one.

Frozen Aircon Causes, Cheapest First
Most iced-up units trace back to one of four causes, and we list them here in the order that costs you least to fix:
A Choked Filter
A filter loaded with a season of dust starves the coil of warm air, and the surface temperature drops until moisture freezes on it. This is the most common cause we see, especially in the small rooms of the older cottages through the original grid.
A Dirty Coil
Dust and grime on the coil fins do the same job as a blocked filter, just closer to the source. The 1901-2 Workmen's Homes cottages around Rose Street have compact living rooms where a wall unit works hard, and the coil clogs faster than most owners expect.
Low Refrigerant Charge
A leak lets gas escape until the remaining charge expands too cold across the coil. The unit ices up, cools poorly and runs longer than it should, and no amount of cleaning will fix it.
A Tired Blower Fan
A worn motor or a failing fan moves less air across the coil even with a clean filter. The symptom often starts as a quiet rattle before the ice appears, so it is worth mentioning any noise you have noticed.

Safe Checks Before You Call Anyone
Two checks are safe and cost nothing, and they rule out the two cheapest causes:
Switch the system off at the controller
Check the filter
Look at the indoor coil once the ice has melted
Do not chip ice off the coil or run the unit in cooling while it is iced. Both risk damage that turns a cheap fix into a compressor replacement.
Do not wait on this
When a Frozen Split System Needs a Technician
If the filter is clean and the ice returns, the fault is inside the system and it will not clear itself. Call us when the unit ices up again within a day or two, when you hear the outdoor unit struggling, or when cooling stays weak after a full thaw.
Our air conditioning repairs team carries gauges to test the refrigerant charge and the gear to check the blower motor on site. Split system air conditioning units of any age are routine work for us.
How it works
How We Fix a Frozen Air Conditioner in Mile End
We start with the airflow path, because filter and coil faults explain most callouts. If those check out, we test the refrigerant charge and locate any leak.
Then we check the blower motor and the controls before we quote a thing. You get the price in writing before any work starts, under our Fixed Upfront Pricing promise.
The warranty side. If the fault came from our workmanship on an earlier job, the Lifetime Labour Warranty covers the return visit at no cost. If the clean itself is the fix, a booked air conditioning cleaning service costs far less than letting the compressor cook itself.
The work is carried out under ARC Licence L162586, RAC01 - Full Refrigeration and Air Conditioning Licence, so refrigerant is handled legally and safely.

Frozen Aircon FAQs
Can I keep running my air conditioner while it is frozen?
No, because the compressor keeps pumping against a blocked coil while the ice spreads, and that strain is how a repairable fault turns into a dead compressor, so switch it off.
How long does it take a frozen unit to thaw out?
A few hours for the ice to melt once the unit is off, but the underlying cause stays, so book a repair rather than restarting a system that will just ice up again.
Does a frozen coil always mean a refrigerant leak?
No, because a choked filter or dirty coil restricts airflow enough to ice the coil on its own, and we test the refrigerant honestly before quoting anything so you only pay for the real fault.
Does a frozen unit need cleaning or repairs?
Often a professional clean sorts it, because dust on the filter and coil is the most common cause, though low gas or a failing fan needs a repair technician, and we will tell you which.
