Air-conditioning repairs in Brisbane
When a system stops cooling, the symptom rarely tells you the cause. A unit low on refrigerant, a blocked coil, a failed capacitor and a control fault can all present as a unit that runs but does not cool, and they are four completely different repairs.
- Licence 90673
- ARCtick L169731
- Fully insured
So the work starts with diagnosis. Hoff finds the fault, explains what it is, and prices the repair once it is known rather than replacing parts hopefully.
What it covers
What's included.
Fault diagnosis
The symptom traced to an actual cause before any parts are quoted.
Refrigerant leaks
A system low on gas has lost it somewhere, so the leak is traced rather than the system simply topped up.
Electrical faults
Capacitors, contactors, isolators and supply issues, handled under the same electrical licence.
Drainage faults
Blocked or incorrectly falling drains causing water to come out of the indoor head.
Noise and vibration
Rattles, hums and vibration traced to mounting, fan or compressor causes.
Repair and retest
The repair carried out and the system run up and checked before handover.
Why people call
Common reasons for this job.
- The system runs but does not cool
- It will not start at all
- Water is coming from the indoor unit
- There is a new noise or vibration
- It cools briefly then stops
- An error code is showing on the controller
Worth acting on
Signs something is wrong.
- Ice forming on pipework or the indoor coil
- A burning or electrical smell from either unit
- The outdoor fan not turning while the unit is running
- Breakers tripping when the system starts
- Cooling that has dropped off noticeably over a short period
How Hoff works
The approach.
Diagnosis first, always. It is the only way to avoid paying for parts that were never the problem.
On refrigerant, a system that is low has a leak, because refrigerant is not consumed. Topping it up without finding the leak means paying again in a few months, so the leak gets traced.
Where a repair does not make economic sense against the age and condition of the unit, Hoff will say so. Replacing a system is a bigger job for him and a bigger cost for you, and you should still get an honest read on which way to go.
Refrigerant work requires ARCtick authorisation (L169731) and the electrical side requires an electrical contractor licence (90673). Hoff holds both. Note that Hoff works Monday to Friday, 7am to 4pm, and does not offer a 24-hour emergency service.
Suitable for
Where this comes up.
AC repairs questions.
Common causes are a choked filter or coil, low refrigerant from a leak, a failed capacitor or fan, or a control fault. They present similarly, which is why the fault is diagnosed rather than guessed.
Refrigerant is not consumed in normal operation, so a system that is low has lost it somewhere. Topping up without tracing the leak means the same problem returns. The leak gets found first.
Usually a blocked condensate drain or a drain that is not falling correctly, though a frozen coil can also cause it. It is worth attending to promptly because the water goes into the wall.
It depends on the age, condition and what has failed. Hoff will give you an honest read even when replacement is the smaller job for him.
No. Hoff works weekdays 7am to 4pm and is not a 24-hour service. Call and he will fit you in as soon as he can.
