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 and nothing goes ahead without your say-so. The work covers wall-mounted split systems, ducted systems and ceiling cassettes, and people most often call us about ice forming on the indoor unit or pipes and air conditioning running but not cooling.
A visit to Shenleybury is planned so we can usually finish in one go, unless a part has to come from the manufacturer.
Some manufacturers make regular servicing by a qualified engineer a condition of their warranty. If that applies to your system, booking the service on time keeps the record straight, and every service is written up.

What we do, step by step
We book the visit for a day and time that suit you, and we keep you posted if anything changes. When we arrive, we check the job against the survey or the pictures you sent. If something is different, we talk it through with you before carrying on. After that, it takes anything from an hour or so to a full day, depending on the fault and the parts. We plan the trip to Shenleybury around you.
- It starts with the symptoms: what the unit is doing, the make and any code on the display.
- At the property, readings and tests narrow the problem down to its cause.
- You get a plain explanation of the fault and a fixed price for putting it right.
- The fix goes in, with any refrigerant work tested and written into the F-Gas records.
- Before leaving, we run it through its modes and write up what was found and done.
Before we arrive
- Find the manual or the paperwork for the system, if you have it

Air conditioning repair around Shenleybury
About 63% of households live in detached or semi-detached houses, according to the last census (2021). Wall bracket, ground pad or flat roof: knowing where the outdoor unit is saves time on the day. There are 2 conservation areas within a mile of the centre of Shenleybury. Day-to-day work on an existing system is not affected; a replacement outdoor unit on a protected building might be.
A photo of the error code and the unit’s rating label helps us plan the repair. When cooling fails at a school like Clore Shalom School, we can time non-urgent repair work around lessons.

FAQs for Shenleybury
Is Shenleybury in your area for air conditioning repair?
Yes, Shenleybury is within the area we cover. Get in touch with the details and we reply the same working day.
Who do I call if my air conditioning fails in Shenleybury out of hours?
Yes: ring the emergency line, day or night, from anywhere in Shenleybury. Tell us the make, model and any error code when you call; repair call-outs start from £75 + VAT.
Can you still repair R410A air conditioning?
Yes. We find and fix the leak, then recharge with R410A and record it in the F-Gas records, and we tell you honestly whether a repair is worth it on an older system.
How much does an air conditioning repair cost?
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. The cost depends on the fault, the parts and access to the units.
Will you work on another installer’s system?
Yes. We work on systems fitted by other installers as well as our own from all the leading brands. Tell us the make and model and send any paperwork you have.
What causes ice on the indoor coil?
Ice is a symptom of low airflow or low refrigerant. A clogged filter, a fan problem or a leak are typical. Switch the system off, let it thaw and call us on 07833 053749 or use the quote form.
How long does the visit take?
Your quote will say how long we expect to be there. As a guide, the work takes anything from an hour or so to a full day, depending on the fault and the parts.
System by system
Fans and compressors
At the centre of the system is the compressor. Compressor faults can sometimes be caused by something else, such as an electrical fault or a refrigerant problem, so we test before condemning it. A failed compressor often raises the repair-or-replace question, and we give you both prices.
Refrigerant leaks
A low refrigerant charge always means a leak. We find it, repair it, pressure test the circuit, evacuate it and recharge to the manufacturer’s charge, and the work is recorded in the F-Gas records.
Why act early in Shenleybury
Small faults rarely stay small. A drip can turn into a damaged ceiling, and a slow leak can leave the compressor straining, so getting it looked at early normally means a simpler repair. Booking before summer means the work in Shenleybury is done before the hot weather.
The pipe route, the height of the units and how we reach them all affect the cost. Each of those is built into the quote and give you a fixed price before any work starts.
