Air conditioning repair in Lampton, done properly

Aftercare tips
So the system stays in good health:
- Write down the fault code if there is one
- Turn it off and let ice clear before the visit
- Only let an F-Gas qualified engineer work on the refrigerant
After a repair, the basics matter: clean filters every few weeks in heavy use and space around the outdoor unit. A yearly service catches problems before they become breakdowns.
Book an annual service. The engineer cleans what you can’t reach and picks up problems before they cause a breakdown, which is far simpler than an emergency repair.
Common problems we fix in Lampton
Rattles, buzzes and grinding sounds tend to be mechanical. Fan bearings, loose casing, leaves or debris in the outdoor unit and vibrating pipework are typical causes and some point to a compressor problem.
If any of these sounds familiar, it’s worth a diagnosis:
- Air conditioning running but not cooling
- A noisy indoor or outdoor unit
- Poor airflow even with clean filters
For a school like Alexandra Primary School, urgent repairs can be booked right away and bigger work in the holidays.
Before booking anyone
- Whether a new circuit is included and who certifies it
- Whose warranty applies, and on what terms
- Exactly what the price includes, from supply and fitting to commissioning
System by system
Ducted and cassette systems
With ducted and cassette units, most of the system is hidden in the ceiling, so access matters. Condensate pumps are common on both, and a failed pump is a frequent cause of water leaks.
Wall-mounted split systems
The single split is the most common system we are called to. Drains, coils, fans, sensors and leaks account for many of the faults and the diagnosis starts with the fault code and the symptoms.
What we do, step by step
Think of the visit in three stages: diagnose, treat and sign off. First comes a careful look at the system or the space, then we do the work, and finally we test, record and explain. The middle part takes longest, and that takes an hour or two to diagnose most faults, with the repair time depending on what we find. A few pictures of the room, the outside wall and the fuse board help us plan a job in Lampton.
- Tell us the make, the symptoms and any error code, and send a photo of the display if you can.
- At the property, readings and tests narrow the problem down to its cause.
- Once the cause is found, we explain it and fix the price for the repair.
- The repair is carried out, and any refrigerant work is leak tested and recorded.
- The system is run and checked in every mode, and we tell you about anything else we noticed.
Getting ready for the visit
- Clear access to the fuse board
- Let us know if the building has a permit or sign-in process
- Tell us about access, such as roof hatches, high walls or locked plant areas
