Air conditioning repair in New Malden
Refrigerant does not get used up, so a low charge means a leak somewhere. Topping up without a repair only delays the next breakdown. We locate the leak, repair it, test, evacuate and recharge and write it up in the F-Gas records. If the problem is water dripping from the indoor unit and air conditioning running but not cooling, we can help.
London systems in New Malden often run long hours in summer, and that is when faults show: weak cooling, water leaks, error codes or a unit that will not start. A photo of the error code and the unit’s label helps us arrive with the right parts in mind.
The records are your system’s health record: what was fitted or found, what was done and when. If anything goes wrong later, it helps the next engineer and the manufacturer and it’s worth keeping safe.

What we are called out for in New Malden
Most indoor unit leaks come back to the condensate. The drain may be blocked or kinked, the condensate pump may have failed, or the unit may not be level, while ice that forms on the coil and then melts can also cause drips.
Reasons to give us a call include:
- A unit that has lost refrigerant
- A system that runs but doesn’t cool the room
- A flashing light and a system that won’t run
Near New Malden station, as anywhere, a photo of the error code on the controller is the quickest way to start a repair.

New Malden questions
Is there an emergency air con repair line for New Malden?
The emergency line is open around the clock, and New Malden is one of the places it covers. Have the make, model and error code ready, and we will talk you through what happens next.
How do I get a quote for air conditioning repair in New Malden?
Send us photos of the room or the system and a few details about the property. We reply the same working day, and the quote is fixed before any work starts.
Can you look at a system you didn’t fit?
Yes. We work on systems fitted by other installers as well as our own, on all the main brands. Tell us the make and model and send any paperwork you have.
Why use an F-Gas certified company?
Anyone installing, repairing or servicing the refrigerant side must be qualified, and their company certified. Ask to see proof before you book anyone, and we’re happy to show ours.
Why is my air conditioning leaking water?
The condensate drain or pump is the usual cause: a blocked pipe, a kinked hose or a failed pump. Switch the unit off to avoid water damage, then call us.
Do I need to service the system to keep the warranty?
That depends on the brand. If servicing is in the terms, missing one could affect a claim and we’ll tell you what your brand asks for.
Why is my air conditioning icing up?
Ice is a symptom of low airflow or low refrigerant. A clogged filter, a fan problem or a leak are typical. Switch the system off, let it thaw and call us on 07833 053749 or write to us at info@aircondoctor.co.uk.
The process
We keep the work area tidy as we go, with sheets down and mess cleared as we go. Any holes, fixings or cable routes are agreed with you before we drill. On site, it takes an hour or two to diagnose most faults, with the repair time depending on what we find. Photos of the room and where the outdoor unit could go let us plan most of a visit to New Malden in advance.
- Diagnosis comes first: codes, electrics, airflow, drain and refrigerant.
- Next, a plain explanation and a fixed price.
- If the repair is not worth doing, we say so and explain the options.
- The treatment: the repair itself, with any leak found and fixed before recharging.
- Finally, a check that it’s working and a record of what we did.
Getting ready for the visit
- Clear the space around the indoor unit, or where it will go
- Mention any managing agent or landlord rules we need to follow
- Find the manual or the paperwork for the system, if you have it
Getting a price
VAT is set out clearly on every quote, with the rate that applies to your job. VAT can differ between homes and businesses and between kinds of work, so we confirm it in writing rather than guess. To get one, phone 07833 053749 or fill in the contact form.
Related advice
For landlords and property managers
Under the GB F-gas rules, responsibility for leak checks is shared between whoever operates the equipment and the engineers who work on it. Where a building is let or managed, the lease or contract should make clear who looks after the system and we are happy to deal with whoever it is.
We regularly work with managing agents. Tell us the property, the work and the access arrangements and we will come back with a fixed-price quote.
When something else is needed
In fairness, there are a few things this work will not fix:
- A building problem rather than a system fault
- Cooling that falls short because the system is too small
- A refrigerant fault on an R22 system (new R22 cannot be used for servicing, so replacement is normally the answer)
If in doubt, give us a ring on 07833 053749 or use the quote form and we’ll say what we think.
Where we work
- Multi-split systems
- Ducted systems
- Ceiling cassettes
