Common problem
Air Conditioner Frozen in Broadview
An air conditioner frozen over is a common call across Broadview once summer gets going. Ice on the indoor coil, the copper pipes or the outdoor unit means the system has stopped absorbing heat properly.
It will not fix itself, and running it iced-up does more damage. We are Broadview's local air conditioning team, and frozen coils are a fault we clear every week through summer.
What this page covers. The causes of the ice, the checks you can safely do yourself, and the point where it needs a licensed technician.
Why Your Air Conditioner Freezes Up
A frozen coil comes down to one thing: not enough warm air moving across it, or not enough refrigerant in it. The moisture in your home's air then turns to frost instead of draining away.
The housing makes it slower to recover. Many Broadview homes are inter-war bungalows and post-war cottages in solid brick and double-brick, and that thermal mass holds the cold once a system ices up, so the thaw drags on longer than it would in a newer build.
Common Causes of a Frozen Aircon
The causes run from cheap to serious. Work through them in this order before you assume the worst.
A clogged filter
A dirty coil or blocked return air
Closed vents or doors
Low refrigerant
A failing fan motor
Safe Checks Before You Call
A few checks are free and safe, and they rule out the simple causes. Switch the system off at the wall first and let the ice melt on its own.
- Check the filter. If it is grey and loaded, clean or replace it.
- Confirm every vent and register is open and unobstructed.
- Make sure the fan setting is on auto, not low, and the mode is actually cooling.
- Look at the outdoor unit for leaves or debris blocking the coil.
If the system ices up again after a clean filter and a full thaw, stop there. Anything past the filter involves refrigerant or electrical work, and that is not a DIY job.

When Ice Means Air Conditioning Repairs
Some frozen coils point at a fault that will not wait. Call us the same day if you notice any of these.
- Ice that returns within a day or two of a proper thaw.
- Hissing near the unit or the refrigerant lines.
- A fan that has stopped turning while the system runs.
- Water pooling under the indoor unit as the ice melts.
Our air conditioning repairs team carries the common parts on the van, so most frozen-coil jobs are sorted in one visit. If the melt water has stained a ceiling, our air conditioner leaking water page covers that follow-on fault.
Questions
Air Conditioner Frozen FAQs
Should I turn off a frozen air conditioner straight away?
Yes, switch it off at the wall and let the ice melt naturally, because running an iced-up coil strains the compressor and turns a small fault into an expensive one.
How long does it take a frozen coil to thaw?
A badly iced coil can take several hours to melt completely, so plan the day around it and resist the urge to chip the ice off the fins.
Will a frozen air conditioner fix itself once it thaws?
It will run again, but the cause is still there, and most frozen coils come back within days unless the filter, coil or refrigerant fault gets properly fixed.
Can low refrigerant cause ice on the pipes?
Yes, a leak drops the coil pressure until the moisture in the air freezes on it, and topping up without finding the leak just sets the same fault up again.
Stop the Freeze Before It Starts
A yearly clean is the best prevention, because clear filters and coils keep the airflow up and the coil above freezing. Book it in spring, before the first heatwave loads the system up. Our air conditioning cleaning page has the detail, and new customers get $50 off first service.
