Greater London · Air conditioning repair
Air conditioning repair in Farnborough, Greater London
Our engineers work in Farnborough on fault finding and repair for split, multi-split, ducted, cassette and VRF air conditioning, whatever the brand. A look at the job first, a fixed-price quote and written records at the end.
- A system that keeps cutting out
- A system that runs but does not cool the room
- Weak airflow from the indoor unit
Why deal with it now?
Leaving a fault seldom makes it go away. A drip can turn into a damaged ceiling, and a slow leak can leave the compressor straining and early diagnosis typically keeps the repair simpler. Allow time for any approvals your building in Farnborough needs.
Every job is different, so each one gets its own fixed-price quote. The equipment, how we reach it, the route between units and the work needed all make a difference.
What you get with us
- Leading brands including Daikin, Mitsubishi Electric and Fujitsu
- Every job looked at before it’s priced
- A 24/7 emergency line
- One number for homes and businesses across London and the South East

Air conditioning repair for homes and businesses in Farnborough
Diagnosis call-outs start 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 a system that won’t switch on and weak airflow from the indoor unit, on ceiling cassettes, VRF systems and wall-mounted split systems.
Many buildings in Farnborough have a managing agent or security desk, so tell us who controls access. Outdoor units on roofs may need a key, a permit or an escort, which is worth sorting before the visit.
Equipment warranty comes from the manufacturer, on its own terms, and we explain those terms on your quote. Each brand sets its own conditions, so we go through them with you rather than leave you to find the small print.

How the visit works
Think of the visit in three stages: look, put right and sign off. First we check the system or the space against the plan, then we do the work, and finally everything is tested, recorded and explained. Most of the time goes on the middle part, and that takes as long as the fault needs, from a quick fix to a return visit for parts. Photos of the room and where the outdoor unit could go let us plan most of a visit to Farnborough in advance.
- First, a few questions by phone or email about the brand, the fault and anything shown on the controller.
- On the diagnosis visit, the engineer tests the system rather than guessing.
- We explain the cause and give you a fixed price for the repair before any work goes ahead.
- The repair is carried out, and any refrigerant work is leak tested and recorded.
- The system is run and checked in every mode, and we tell you about anything else we noticed.
Getting ready for the visit
- Clear access to the fuse board
- Tell us about access, such as roof hatches, high walls or locked plant areas
- Let us know where we can park and unload

Common questions in Farnborough
Is there an emergency air con repair line for Farnborough?
Farnborough 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.
Is Farnborough in your area for air conditioning repair?
We do: Farnborough falls inside our working area. Tell us a little about the job and we will take it from there.
How soon will you get back to me?
On the same working day you contact us. After that, we agree a survey, diagnosis or installation date that suits you, with a fixed price before work starts.
Will I get records for the system?
Yes, on every job. New installations come with commissioning details, F-Gas records and warranty information, while repairs and services get a written note of what was found and done.
Why is there ice on my air conditioning pipes?
Ice is a symptom of low airflow or low refrigerant. A clogged filter, a fan problem or a leak are typical. Turn it off, let the ice melt and phone us on 07833 053749 or email us.
Why is my air conditioning blowing warm air?
Common causes are a blocked filter, the wrong mode or set temperature, an outdoor unit that cannot breathe, a failed sensor or board, or low refrigerant from a leak. Start by checking the filter and the mode, and if that doesn’t fix it, ring us on 07833 053749 or use the quote form.
Can you repair an R22 air conditioning system?
Servicing with new R22 isn’t allowed, because it depletes the ozone layer. Some non-refrigerant faults can be repaired if parts are available, but a leak normally makes replacement the sensible route. We explain the options and quote for a new system if that is the answer.
Air conditioning repairs in Farnborough: local notes
In London buildings, outdoor units can be on roofs or in light wells, so let us know where yours is. The Farnborough Village Conservation Area lies close to the centre of Farnborough, within about a third of a mile. Listed buildings are part of the picture here: about 11 within half a mile of the centre, such as Church of St Giles the Abbot (grade II*). Day-to-day work on an existing system is not affected; a replacement outdoor unit on a protected building might be.
If the display shows a code, write it down: it helps narrow down the fault.

When to call us in Farnborough
When ice forms on the pipes or coil, something else is wrong. It normally points to poor airflow, such as a clogged filter or a fan problem, or to a refrigerant leak. Turn it off and let the ice melt, then call us.
Look out for these signs:
- A suspected refrigerant leak
- Ice forming on the indoor unit or pipes
- A unit that won’t start
When cooling fails at a school like Farnborough Primary School, we can time non-urgent repair work around lessons.
Questions to ask before you book
