Common problem
Air Conditioner Not Cooling in Greenwith
The system runs, the fan blows, and the air coming out is barely cooler than the room. An air conditioner not cooling is the most common fault we get called to across Greenwith, and it usually has a straightforward cause.
Greenwith homes are almost entirely detached brick-veneer builds from the Delfin release. Many of the first-stage systems have been working flat out every summer since they went in.
In detail
Why Your Aircon Stops Cooling in Greenwith
A unit that runs but does not cool is usually one of five faults. Some are cheap fixes, some point at a bigger decision, and the order below runs from cheapest to most serious.
Dirty filters and coils
Dust chokes the return air filter and the indoor coil, so cold air never reaches the room. The two-storey homes in the later release stages have ceiling spaces that collect it fast, and a thorough clean often restores full cooling on its own.
Low refrigerant charge
Refrigerant does not wear out, so a low charge means a leak somewhere. It is a licensed repair, and our RAC01 - Full Refrigeration and Air Conditioning Licence covers finding the leak, fixing it and recharging the system legally.
Thermostat and settings
It sounds obvious, but a system left on fan-only, or a sensor knocked out of position, will run all day without cooling. We check the simple things first before anyone assumes the worst.
Duct leaks
A ducted system can be cooling perfectly and still leave rooms warm, because split or crushed ducting in the roof is dumping cold air into the ceiling space. The hilly ground here means roof cavities vary block to block, and we inspect the runs rather than guessing.
Compressor wearing out
A tired compressor runs but loses its pull-down. On units from the late 1980s and 1990s stages, that is often the fault that ends the conversation, and we will tell you honestly when repair stops making sense.

Simple Checks Before You Call
Three safe checks take five minutes and sometimes solve the problem outright:
Filter
Mode and temperature
Outdoor unit
Stop there. Never open the electrical cabinet or touch refrigerant lines, because both are licensed work for good reason.
Do not wait on this
When to Call for Air Conditioning Repairs
Call us when the checks change nothing, when the unit trips the switchboard, or when ice forms on the pipes. Ice on a system in 40-degree heat points at low refrigerant or a blocked coil, and running it flat out in that state damages the compressor.
We hold 24/7 emergency availability, and a Within-the-Hour Response applies to urgent faults where availability allows.

Cooling Problems We See Around Greenwith
Whole streets here had systems installed within a few years of each other, so units age together and the same faults turn up street by street.
The newer streets. The 2017 expansion area absorbed from Salisbury Heights runs newer equipment, but its two-storey builds work the indoor units harder through long heatwaves.
Either way, the pattern is the same: a system that struggles on the third hot day in a row is telling you something.
If the air is warm rather than cool, our air conditioner blowing warm air page covers that version of the fault.

Air Conditioner Not Cooling FAQs
Why does my air conditioner run but not cool?
The usual culprits are a blocked filter, a coil buried in dust or low refrigerant from a leak, and all three are common in the first-release Greenwith homes where systems have run hard for years.
Can I check anything myself before booking a repair?
Yes, check the filter, the thermostat mode and the outdoor unit for blockages, but never open the refrigerant circuit or the electrical cabinet, because refrigerant and live parts are licensed work only.
How fast can you get here when the cooling dies?
We offer 24/7 emergency availability and a Within-the-Hour Response for urgent faults where availability allows, which matters on the third 40-degree day when the house will not pull down.
Is an old unit worth repairing or should it be replaced?
If the system is past fifteen years and the compressor or control board has failed, replacement usually wins on running cost, and we test it honestly and quote both paths before you decide.
