How we handle air conditioning repair in Walkern
A diagnosis call-out is from £75 + VAT. Once we know the cause, you get a fixed price for the repair before any work goes ahead, so you can decide with the facts in front of you. Common call-outs are for ice forming on the indoor unit or pipes and a system that won’t switch on, on wall-mounted split systems, heat pumps and ducted systems.
Outdoor units in a place like Walkern can be near hedges and fields, and a coil clogged with leaves or seeds is a common cause of weak cooling.
The records are your system’s health record: a dated account of the work and the readings we took. If anything goes wrong later, it helps the next engineer and the manufacturer, so keep it safe.

After we have gone
How well a system lasts depends on use and care. We suggest:
- Turn it off and let ice clear before the visit
- Ask for the leak to be found, not just a top-up
- Check the filter, the mode and the set temperature before calling us
Keep the filters clean and the outdoor unit clear after the repair: clean filters every few weeks in heavy use and space around the outdoor unit. A yearly service catches problems before they become breakdowns.
Give the outdoor unit space. Anything blocking the outdoor unit makes the whole system strain, and debris can get into the fan.
The process
The visit goes in the diary at a time that works for you, and we keep you posted if anything changes. On arrival, the engineer compares the job with the survey, your pictures or the details you gave us. If something is different, we talk it through with you before carrying on. From there, the work takes as long as the fault needs, from a quick fix to a return visit for parts. If a lane or gateway near Walkern is tight for a van, let us know and we will plan for it.
- Diagnose: test the system until the cause is clear.
- Next, a plain explanation and a fixed price.
- Where a repair doesn’t make sense, you’ll hear it from us, with the alternatives.
- The treatment: the repair itself, with any leak found and fixed before recharging.
- The sign-off: the system tested in operation and the work recorded.
Preparing for the visit
- Plan for pets to be kept clear during the visit
- Give us access to the outside wall, roof or yard where the outdoor unit sits
- Tell us about access, such as roof hatches, high walls or locked plant areas
Getting a price

Advice
Common questions in Walkern
Can you do air conditioning repair in Walkern?
Yes. We work across London and the South East from our base in East Grinstead, and Walkern is part of that. To start, call us on 07833 053749 or drop us a line with a few photos.
Will you come out to Walkern?
Yes. Walkern is within the area we cover across London and the South East. A few photos and the postcode are enough to get things started.
When will I hear back?
The same working day. Then we agree a date that works for you, with a fixed price before work starts.
Why is my air conditioning leaking water?
Usually a blocked or kinked condensate drain, a failed condensate pump or a unit that isn’t level. Ice on the coil from low airflow or low refrigerant can also melt and drip. Switch the unit off and call us on 07833 053749 or drop us a line.
Does servicing affect my warranty?
That depends on the brand. Where servicing is a condition, a missed service could give the manufacturer grounds to refuse a claim and we’ll tell you what your brand asks for.
Why is not my air con cooling?
It could be a dirty filter, the wrong settings, a blocked outdoor unit, a sensor or board fault, or a refrigerant leak. Start by checking the filter and the mode, then give us a ring on 07833 053749 or send an email if it’s still not cooling.
Who is responsible for leak checks?
The operator of the equipment, working with qualified engineers. Systems below 5 tCO2e fall outside the set leak check intervals, while larger ones need checks at least every 12 months, or every 6 months from 50 tCO2e. We’ll work out which band applies to yours.
When something else is needed
We won’t sell you work that doesn’t address the problem, so these are the things it will not cover:
- An R22 system that has lost its refrigerant
- A power cut or a fault on the incoming supply to the building (that’s for the network operator)
- An old system with obsolete parts
If you’re not sure, just call 07833 053749 or drop us a line and we will give you a straight answer before you book.

What else we do in Walkern
Safe owner checks
For air conditioning, cleaning the indoor unit’s filters is the main job owners can do, if the manual says so. 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.
There are a few things you can safely do yourself: keeping the outdoor unit clear, checking the mode and set temperature, and the routine cleaning in the manual. Anything inside the units, the electrics and the refrigerant is engineer’s work.
From one of our customers
“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.”
