Common problem
Air Conditioner Frozen in Salisbury Plain
Ice on your indoor unit means an air conditioner frozen solid is no longer cooling your Salisbury Plain home. Salisbury Plain Air Conditioning finds the cause, thaws it properly and stops it coming back.
Welcome
Frozen Air Conditioner Help From the Aircon Team Salisbury Plain Trusts
A frozen coil is one of the most misunderstood faults in air conditioning, because the unit looks broken but usually is not finished yet. Homes across Salisbury Plain call us when the ice keeps returning, and the fix is often simpler than it looks.
In detail
Why Your Split System Ices Up
A split system freezes when the coil gets colder than it should, or when warm air stops reaching it. Both come back to a handful of common causes, listed from cheapest to fix first.
Low airflow
A choked filter or a coil caked with dust starves the coil of warm air, so it drops below freezing. This is the most common cause and the cheapest to fix, often in one visit.
Low refrigerant
A slow leak drops the pressure in the coil until it ices over, starting at the joints and working back. Low gas is never a top-up job, because the leak has to be found and sealed first.
A tired fan motor
Bearings wear out in units that have run as long as the house has stood, and a slowing blade moves less air. The 1970s brick homes along Stanbel Road often still carry original systems, and worn fans show up there first.
Running it too hard
A system set to 18 degrees on a 40-degree day runs flat out for hours, and the coil can ice before the room ever gets there. Bumping the setpoint up a few degrees often prevents the whole problem.

Safe Checks Before You Call
A couple of checks are safe for anyone, and they rule out the simple stuff before you spend a cent.
- Switch the system off or to fan only, and let the ice melt completely
- Pull the filter out and hold it up to the light, then wash it if the light does not get through
- Check nothing is blocking the indoor unit, like curtains, furniture or a closed door
- Make sure the setpoint is not sitting at the bottom of the range
Anything past the filter involves refrigerant or wiring, and that is licensed work. Leave it with us.

When a Frozen Unit Needs an Aircon Repair
Call us when the ice comes back after a clean filter and a proper thaw, or when the unit hums but the airflow feels weak. Those signs point to a refrigerant leak or a failing fan, and neither fixes itself.
A coil that ices repeatedly wears the compressor, and the compressor is the part you never want to lose. Getting it looked at this week beats replacing the whole system next summer.
How it works
How We Fix a Frozen Air Conditioner
- 01
Thaw and inspect
We let the coil thaw fully, because diagnosing through a block of ice tells you nothing. Then we inspect the filter, the coil and the fan for the obvious causes first.
- 02
Find the real fault
If the simple causes are ruled out, we check refrigerant pressures and look for the leak, along with testing the fan motor under load. You get told exactly what we found.
- 03
Fixed price quote
Under our Fixed Upfront Pricing, you get a fixed quote before any work starts. No hourly rates, no bill shock, and no surprises when the invoice lands.
- 04
Repair and test
We carry common parts on the van, so most causes are fixed the same visit. The system then runs through a full test to confirm the coil holds temperature without icing.
Good to know
Frozen Air Conditioner Questions, Answered
Why is my air conditioner frozen even on a hot day?
Ice forms when airflow over the coil drops or refrigerant runs low, so the coil sits below freezing even while the room swelters. The ice then blocks the airflow that would clear it.
How long should I leave a frozen unit off?
Run the fan only, or switch everything off, and give it a full day to thaw. Never chip at the ice, because bent fins turn a simple thaw into a coil repair.
Can a frozen air conditioner be repaired, or does it need replacing?
Most frozen units are repaired rather than replaced. A blocked filter, a tired fan motor or a refrigerant leak all have straightforward fixes, and we quote the honest option before any work starts.
Do you offer emergency call-outs for a frozen system?
Yes, we run 24/7 emergency availability, and urgent faults get a within-the-hour response where availability allows. A frozen unit in a heatwave counts as urgent, so call and we will fit you in.
