Air conditioning repair in Old Chiswick
A sealed system shouldn’t lose refrigerant, so a low charge means a leak somewhere. Simply adding gas means it will leak away again. We locate the leak, repair it, test, evacuate and recharge and write it up in the F-Gas records. The work covers ducted systems, wall-mounted split systems and ceiling cassettes, and people most often call us about a unit that barely blows any air and air conditioning running but not cooling.
Many buildings in Old Chiswick have a managing agent or security desk, so tell us who controls access. Roof access can need keys or permits, which is worth sorting before the visit.
Refrigerant work is written up in the F-Gas records: the work carried out, the refrigerant involved and the quantities. Keep the records with the manual and the warranty documents, as a manufacturer or a future engineer may ask to see them.

Will skipping a service affect the warranty?
For some brands, yes. Send us the make and model and we’ll tell you what the manufacturer expects, and book the service at the interval they recommend.
Do you survey before quoting?
Yes, every time. We diagnose before we treat: the survey tells us what the job needs and how to do it, and the quote is based on that.

Yes. Tell us what you have and how it’s used and we will propose a schedule and quote for it. Leak checks required by the F-gas rules can be built in for larger systems.
Do you work on all makes?

Will I get records for the system?
Yes, always. A new system comes with commissioning details, F-Gas records and the manufacturer’s warranty information, and repairs and services get a record of the work.

Related advice
Do you need air conditioning repair in Old Chiswick?
Leaks tend to start where pipes are joined: flare connections, brazed joints and valves, or pipework damaged or rubbed through by vibration. Coils can corrode and leak too and many leaks are slow enough to go unnoticed for a while.
Common reasons people call us include:
- A system that keeps cutting out
- A fault code on the display
- Ice forming on the indoor unit or pipes
If a system fails at a school such as The William Hogarth Primary School, our 24/7 line takes the call, and planned repairs can wait for the holidays.
Before you book anyone
- If the figure could change on the day
- Whose warranty applies, and on what terms
- If the quote is based on a survey, pictures or a diagnosis

What you can do yourself, and what needs us
Never try to top up, release or handle refrigerant yourself. The law requires anyone working on equipment containing F gas to hold the right qualifications, and the company to be certified, and refrigerant lines can cause cold burns. If you suspect a leak, switch the system off and call us.
For air conditioning, cleaning the indoor unit’s filters is the main job owners can do where the manufacturer’s manual explains how. They come out, get a gentle clean and go back only when they’re dry. For a heat pump, the main owner jobs are a clear outdoor unit and sensible control settings.

“Office air con broke down in the July heatwave. Called at 8am, engineer was here by noon and fixed within 2 hours. Brilliant emergency response. They now hold the service contract for the whole building.”
