Signs you need air conditioning repair in Old Oak Common
Error codes are the system telling you it has found a fault. Codes differ by brand, and one code can cover several faults, so we read the code and then test to confirm. Sensors, communication faults between the units and circuit boards are frequent culprits.
The things we’re asked about most are:
- A fault code on the display
- Rattling, buzzing or grinding noises
- A system that needs topping up again
For a home or office near Willesden Junction station, tell us the make, model and error code when you call, so we can plan the repair.

How long does the visit take?
Your quote will say how long we expect to be there. As a guide, the work takes as long as the fault needs, from a quick fix to a return visit for parts.
Do you work on systems someone else installed?
Yes. We look at it first and tell you what we find, including anything about the original installation that needs putting right. You get a fixed price before any work goes ahead.
Will you make a mess?
We put dust sheets over floors and furniture near the work first, and we tidy up as we go. At the end, we clear up and show you what we have done.
Different systems, different jobs
Multi-split systems
A multi-split links several indoor units to one outdoor unit, so a fault outside can affect every room, while a fault inside may affect only one. It tells us where to look first.
Fans and compressors
Fan motors and bearings wear over time, often starting with a noise or weaker airflow. A worn fan motor can typically be replaced where the parts are available.
The process
Each visit runs to the same pattern: check the plan with you, put the dust sheets down, carry out the job, check the system and explain it all to you. The visit itself takes as long as the fault needs, from a quick fix to a return visit for parts. Managed buildings in London often need contractors booked in, and we can deal with the agent for a job in Old Oak Common.
- We start with what the unit is doing, the make and any code.
- The engineer diagnoses the fault on site, testing rather than guessing.
- You get the cause explained and a fixed price for the repair.
- Once agreed, the repair goes ahead.
- We test the system in operation and leave you a note of the fault and the fix.
Getting ready for the visit
- Let us know if the units are on a roof, a high wall or in a locked area
- Dig out any previous service or F-Gas records
- Let us know if the building has a permit or sign-in process
