When Your Aircon Stops Working, Everything Gets Harder
An air conditioner that has stopped cooling, started dripping water, or begun making a strange noise is telling you something is wrong. Left alone, a small fault usually turns into a bigger one. A unit that is low on gas keeps running and running, which pushes up your electricity bill and wears out the compressor, and the compressor is the most expensive part to replace.
For a home, that means an uncomfortable bedroom or lounge right when you need the cooling most. For a guesthouse or office, it means uncomfortable guests and staff, and that reflects on you. The sooner we look at it, the cheaper and simpler the fix tends to be.
We work on most makes and models, and we keep common parts on the van, so a lot of faults get sorted in a single visit.

Air Conditioning Repairs We Handle
Whatever your unit is doing, or not doing, we can find the cause and fix it:
Aircon Not Cooling
If your unit is running but the air coming out is warm or barely cool, it usually points to low refrigerant gas, a dirty filter, or a failing compressor. We find the actual cause instead of just topping up gas and sending you on your way.
Water Leaks
A unit dripping water inside the room normally means a blocked drainage pipe or a frozen coil. We clear the blockage, work out why it happened, and make sure it does not come straight back.
Strange Noises
Rattling, grinding or buzzing sounds are worth checking early. They often mean a loose part or a fan motor starting to fail. Catching it now is far cheaper than waiting for it to seize up.
Gas Top-Ups and Regas
A unit that has slowly lost its cooling power is often low on refrigerant. We look for the leak first, repair it, and then regas the system so you are not paying for gas that escapes again a month later.
Electrical Faults
A unit that trips the power, will not switch on, or shuts off by itself often has an electrical fault. Our registered electricians handle this side safely.

Sometimes the problem is the remote, the wiring, or the control board. We work through it step by step and tell you honestly whether a repair makes sense or a replacement is the better call.
Learn More →Aircon Servicing and Maintenance
Most aircon breakdowns can be avoided. A unit that gets serviced once a year runs more efficiently, uses less electricity and lasts years longer. Here is what a service covers:
Filter and Coil Cleaning
Dust and grime build up on the filters and coils, which makes the unit work harder and cool less. A proper clean restores the airflow and keeps your running costs down. It also keeps the air in the room cleaner, which matters if anyone in the home has allergies.
Gas and Pressure Check
We check the refrigerant level and the pressures so the unit is cooling at full strength. Catching a slow gas leak early saves the compressor from running under strain and failing on you later.
Electrical and Component Check
We go over the wiring, connections and moving parts so nothing is working loose or starting to wear. Small things get tightened and sorted before they turn into a callout on a hot day.
Drainage Check
We make sure the drainage is running clear, so the unit is not going to start leaking water into the room a few weeks down the line.
For rental properties, guesthouses and estates where units run hard all season, twice a year works better. We set up servicing schedules so you are not the one keeping track of it. If you look after several units, take a look at our commercial air conditioning services.
