Air conditioning repair in Willesden Green
Refrigerant doesn’t get used up, so if it’s low, there’s a leak. Simply adding gas means it will leak away again. We locate the leak, repair it, test, evacuate and recharge, then record it in the F-Gas records. We are often asked to deal with a noisy indoor or outdoor unit and a fault code on the display, across multi-split systems, heat pumps and ducted systems.
In Willesden Green, as across London, air conditioning works hard in hot spells, and that’s when faults show: weak cooling, water leaks, error codes or a unit that won’t start. A photo of the error code and the unit’s label helps us arrive with the right parts in mind.
For a fault on a system that may still be under warranty, send us the make, model and installation date. We’ll explain how the manufacturer’s terms are likely to apply before anything chargeable is done.

Common problems we fix in Willesden Green
When ice forms on the pipes or coil, something else is wrong. It typically points to poor airflow, such as a clogged filter or a fan problem, or to a refrigerant leak. Switch the system off and let it thaw before calling us.
Most people get in touch after spotting something like this:
- An error code or flashing light on the unit
- Rattling, buzzing or grinding noises
- A unit that barely blows any air
Schools such as Donnington Primary School can report a fault on the 24/7 line and have non-urgent work done out of term.

Common questions in Willesden Green
Do you cover Willesden Green for emergency air conditioning repairs?
Willesden Green is within our area, and the emergency line is open 24/7. A diagnosis call-out starts from £75 + VAT, and knowing the brand and the symptoms helps us plan it.
What’s the best way to get a price for air conditioning repair in Willesden Green?
Start with a short message: the address, what you need and a picture or two. We reply the same working day, and the quote is fixed before any work starts.
How does the warranty work?
It’s the manufacturer’s, and the terms are theirs. Some brands make regular servicing a condition, so keep your service records.
What does F-Gas certified mean?
F-Gas certification shows a company is approved to work on equipment containing fluorinated gases, such as the refrigerant in air conditioning and heat pumps. That isn’t optional: it’s required by law, and we hold it.
Why is my air conditioning leaking water?
Normally a blocked or kinked condensate drain, a failed condensate pump or a unit that is not level. Ice on the coil from low airflow or low refrigerant can also melt and drip. Turn it off and ring 07833 053749 or use the quote form.
Why is my air conditioning icing up?
Ice is a symptom of low airflow or low refrigerant. Blocked filters, a failing fan or a leak are the common causes. Turn it off, let the ice melt and call 07833 053749, or email if that’s easier.
Do you offer maintenance contracts?
Yes. Send details of the systems and how they’re used, and we’ll suggest a schedule with a fixed price. That can include the leak checks the F-gas rules require for larger systems.
What we do, step by step
Every visit follows the same order: check the plan with you, protect the area, carry out the job, check the system and talk you through it. The visit itself takes a single visit for many faults, while some repairs need a second visit once parts arrive. If your building in Willesden Green has a managing agent, a concierge or sign-in rules, mention them when you book.
- Diagnosis comes first: codes, electrics, airflow, drain and refrigerant.
- Then the prescription: what’s wrong and what it will cost to put right.
- Where a repair doesn’t make sense, you will hear it from us, with the alternatives.
- Then the fix, with leaks repaired before any refrigerant is added.
- The sign-off: the system tested in operation and the work recorded.
Before we arrive
- Make sure someone can let us in at the agreed time
- Clear the space around the indoor unit, or where it will go
- Mention any roof access, ladders or high-level work

Advice
Looking after it afterwards
A little care keeps the system in better shape. Our advice:
- Leave space around the outdoor unit
- Let any ice thaw before the engineer arrives
- Have the system serviced once a year
Where a repair needs parts, we explain what’s been ordered and agree the return visit with you. We do not promise dates we can’t control, so we keep you posted.
Have the system serviced once a year. A service cleans the coils and drain, checks the electrics and the refrigerant circuit and catches small faults early, which is far simpler than an emergency repair.
Different systems, different jobs
Wall-mounted split systems
The indoor and outdoor units of a split communicate through a cable. Communication faults show up as error codes, and we test the cable, the boards and the connections to find the cause.
Ducted and cassette systems
With ducted and cassette units, most of the system is hidden in the ceiling, so access matters. Many have condensate pumps, and pump failures are a common cause of ceiling leaks.
