FAQs for Oxford
Can I get a fixed-price quote for air conditioning repair in Oxford?
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.
Can you do air conditioning repair in Oxford?
We do: Oxford falls inside our working area. Tell us a little about the job and we’ll take it from there.
How quickly will you reply?
The same working day. Then we agree a date that works for you, with a fixed price before work starts.
Can you come out for an emergency air conditioning repair?
Yes, 24/7. Emergencies include water coming through a ceiling or a critical room overheating and we’ll tell you what to do first. The number is 07833 053749.
Can I do any of the installation myself?
Anything that involves the refrigerant needs an F-Gas qualified engineer from a certified company. That is a legal requirement, and it also matters for the manufacturer’s warranty. We can quote for the whole job, from supply to commissioning.
My air con is showing an error code. What should I do?
The code is the system’s own clue to the fault, but it isn’t the whole answer. Write down the code and turn the unit off if it has stopped, then ring 07833 053749, or email if that’s easier.
Why isn’t my air con cooling?
Common causes are a blocked filter, the wrong mode or set temperature, an outdoor unit that can’t breathe, a failed sensor or board, or low refrigerant from a leak. Start by checking the filter and the mode, then ring 07833 053749 or email us if it’s still not cooling.
Air conditioning repair for homes and businesses in Oxford
For breakdowns that cannot wait, there’s a 24/7 emergency line, from an overheating comms room to water leaking from a unit. Call 07833 053749 and tell us the make, the symptoms and any error code and we’ll talk you through what happens next. The work covers heat pumps, wall-mounted split systems and VRF systems, and the jobs we see most are poor airflow even with clean filters and a unit that won’t start.
Across Oxford, we work on the leading makes of air conditioning, from single wall units to multi-split systems. If a repair does not make sense on an older system, we will say so and give you the options.
Warranty on the equipment is the manufacturer’s own, on the manufacturer’s terms, and we explain those terms on your quote. Each brand sets its own conditions, and we’re happy to talk you through them.

When air con fails in Oxford
The middle of Oxford is part of the Headington Hill Conservation Area. 4 conservation areas lie within a mile of central Oxford. Historic England lists about 50 buildings and structures within half a mile of the centre of Oxford, including Chapel of St Bartholomew (grade I). For most visits that makes no difference. It only comes up when an outdoor unit has to be replaced on a protected building. The Valuation Office Agency’s council tax figures put about 59% of homes in and around Oxford before 1919, and the last census (2021) found about 40% of households in terraced houses. With a terrace, access to the rear for the outdoor unit is the main thing to tell us.
If the display shows a code, write it down: it helps narrow down the fault. When cooling fails at a school like East Oxford Primary School, we can time non-urgent repair work around lessons.

What affects the cost of air conditioning repair
The survey or diagnosis tells us what the work involves. We look at:
- The condition of any existing system
- What electrical work the job needs
- The number of rooms, units or zones
Whatever the property, the quote works the same way: what’s needed, how we reach it, the parts and the labour. Ask for a fixed-price quote and we’ll go through it with you.
What we need to know
When you contact us, it’s useful to have:
- The outside wall, roof or yard where the outdoor unit sits or would go
- Any error code or flashing light on the display
- The fuse board and where it is in the property
Published ranges are a starting point; the quote is built on your property, because every property is different. Once we’ve looked at the job, from photos or on a survey, you get a fixed price. To get going, phone us on 07833 053749, or email if that’s easier.
What air conditioning repair can’t fix
Before you book, it helps to know what’s not included:
- A power cut or a fault on the incoming supply to the building (that’s for the network operator)
- A system that was undersized for the room in the first place (that needs a bigger system, not a repair)
- A refrigerant fault on an R22 system (new R22 can’t be used for servicing, so replacement is usually the answer)
If you are not sure, just ring us on 07833 053749 or send an email and we will give you a straight answer before booking.
What we work on in Oxford
- VRF systems
- Heat pumps
- Multi-split systems
- Wall-mounted split systems
- Ducted systems
- Ceiling cassettes
Different systems, different jobs
Multi-split systems
A multi-split links several indoor units to one outdoor unit, so we check whether the fault is in one room or the shared outdoor unit. That shapes the diagnosis and the repair.
Condensate drains and pumps
We clear the drain, test the pump and check the fall, so the water goes where it should. If a pump has failed, we replace it and test it before we leave.
How it works
The visit has three parts, a bit like a doctor’s appointment: diagnose, treat and sign off. First we check the system or the space against the plan, then the work itself, and finally we test, record and explain. Most of the time goes on the middle part, which takes a single visit for many faults, while some repairs need a second visit once parts arrive. In Oxford, we plan business installs and repairs around opening times.
- Describe the problem and the brand, and mention any code on the display.
- The engineer diagnoses the fault on site, testing rather than guessing.
- The fault is explained simply and the repair priced up front.
- Once you are happy, the repair is done and any refrigerant work recorded.
- It’s tested running, and the write-up is left with you.
Preparing for the visit
- Make sure we can reach the outdoor unit, or where it will go
- Move furniture away from the wall where we will be working
- Tell us about parking and loading
