Farnham Common air conditioning repair
Air conditioning repair in and around Farnham Common, from a site survey or diagnosis to sign-off and a fixed price agreed before any work starts.
- A unit that won’t start
- A system that needs topping up again
- An error code or flashing light on the unit
What owners can safely do
Keep a note of anything odd: an error code, a new noise, a drip, a smell or a change in how well the system heats or cools. It makes our diagnosis quicker, and a photo of the display helps even more.
Do not move, re-route or disconnect units or pipework yourself. Moving a unit involves the refrigerant circuit, so it needs an F-Gas qualified engineer, and the electrics need care too. If you need something moved, we can quote for it.
How we handle air conditioning repair in Farnham Common
Our emergency line runs 24/7 for urgent breakdowns, from an overheating comms room to water leaking from a unit. Ring 07833 053749 with the make, what’s happening and any code, and we will agree the next steps. We are often asked to deal with rattling, buzzing or grinding noises and a system that keeps cutting out, on ducted systems, VRF systems and multi-split systems.
Outdoor units in a place like Farnham Common can be near hedges and fields, and a coil clogged with leaves or seeds is a common cause of weak cooling.
Any work on the refrigerant circuit is recorded: what was done, the refrigerant type and any amount added or recovered. Keep the records with the manual and the warranty documents, as a manufacturer or a future engineer may ask to see them.

How it works
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. The visit takes as long as the fault needs, from a quick fix to a return visit for parts. For a village like Farnham Common, tell us about narrow lanes, gates and parking when you book.
- First the diagnosis: fault codes read, electrics and airflow checked, drain and refrigerant tested.
- Then the prescription: what’s wrong and what it will cost to put right.
- Where a repair does not make sense, you’ll hear it from us, with the alternatives.
- Then the fix, with leaks repaired before any refrigerant is added.
- Finally, a check that it’s working and a record of what we did.
How to prepare
- Let us know where the consumer unit is
- Make sure we can reach the outdoor unit, or where it will go
- Make sure someone can let us in at the agreed time

Other services in Farnham Common
Farnham Common: your questions answered
Is Farnham Common within the area you cover?

Do you cover Farnham Common for air conditioning repair?
Yes. Farnham Common is one of the places we cover. Tell us a little about the job and we will take it from there.
Do you have a 24/7 line for breakdowns?
Yes. We have a 24/7 emergency line for urgent breakdowns. Call 07833 053749 and tell us the make, the symptoms and any error code, and we’ll agree the next steps with you.
Do you provide F-Gas records?
Yes, always. 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.
Who has to arrange F-Gas leak checks?
Whoever operates the equipment, together with the technicians who service it. Larger systems need regular checks: at least every 12 months from 5 tCO2e and every 6 months from 50 tCO2e. We can tell you which band your system falls into.
Why is my air conditioning showing a fault code?
An error code points us in the right direction, but testing confirms the cause. Note the code and switch the system off if it isn’t working, then ring us on 07833 053749 or send an email.
Why does my air conditioning run but not cool?
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. Check the filter and the settings first, and if that does not fix it, ring us on 07833 053749 or write to us at info@aircondoctor.co.uk.
What air conditioning repair cannot fix
In fairness, there are a few things this work will not fix:
- A refrigerant fault on an R22 system (new R22 can’t be used for servicing, so replacement is usually the answer)
- A supply fault outside the property
- Cooling that falls short because the system is too small
If in doubt, ring 07833 053749 or fill in the contact form and we will say what we think.
What we work on in Farnham Common
- Ceiling cassettes
- VRF systems
- Wall-mounted split systems
- Heat pumps
- Multi-split systems
- Ducted systems
Why deal with it now?
If your system uses R22, the options are narrower. R22 is an ozone-depleting refrigerant and new R22 can’t be used for servicing, which typically makes replacement the sensible route after a refrigerant fault. We will tell you honestly and quote for a replacement if it makes sense. Dealing with it now is typically simpler than a breakdown later.
Putting the work off seldom saves money. Faults and wear in a system tend to grow, and a struggling system uses more electricity to do less. If you’re not sure what’s needed, call 07833 053749 or write to us at info@aircondoctor.co.uk and we will give you an honest view and a fixed price.
