Air conditioning repair in Langley Bottom, done properly
Refrigerant doesn’t get used up, so a low charge means a leak somewhere. Simply adding gas means it will leak away again. We locate the leak, repair it, test, evacuate and recharge, then record it in the F-Gas records. We are often asked to deal with a system that keeps cutting out and a system that runs but doesn’t cool the room, across VRF systems, ducted systems and heat pumps.
We plan the trip to Langley Bottom so the repair can be finished in one visit where possible, unless a part has to come from the manufacturer.
Looking after a system is mostly common sense: clear space around the outdoor unit, the cleaning the manual describes and a service at the recommended interval. That also helps where the warranty terms ask for regular servicing.

How the job changes from property to property
Refrigerant leaks
If the charge is low, there’s a leak somewhere. We find it, repair it, pressure test the circuit, evacuate it and recharge to the manufacturer’s charge and every step is recorded.
Fans and compressors
At the centre of the system is the compressor. Before blaming the compressor, we check the electrics and the refrigerant circuit. A failed compressor often raises the repair-or-replace question, and we give you both prices.
Pricing air conditioning repair in Langley Bottom
You’ll get a fixed price before work begins. It takes into account:
- The condition of any existing system
- Whether the existing supply is suitable
- Whether we need access equipment for high-level work
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 are not sure what’s needed, ring us on 07833 053749 or fill in the contact form and we will give you an honest view and a fixed price.
Helping us quote
The more you tell us, the more accurate the quote. With your enquiry, please include:
- A short video of any fault, such as a noise or a flashing light
- The address and the type of property
- Your installation or service records
Some jobs can be priced from photos, while others need a survey. Bigger systems, commercial sites and awkward pipe routes are normally surveyed on site. Either way, you get a fixed price before any work is booked.

Your questions about air conditioning repair in Langley Bottom
Do you cover Langley Bottom for emergency air conditioning repairs?
The emergency line is open around the clock, and Langley Bottom is one of the places it covers. Have the make, model and error code ready, and we’ll talk you through what happens next.
Is Langley Bottom in your area for air conditioning repair?
We do: Langley Bottom falls inside our working area. To start, phone 07833 053749 with a few pictures.
How long will you be on site?
It depends on the job, but in most cases it takes as long as the fault needs, from a quick fix to a return visit for parts. We will give you a firmer idea when we quote.
Why does my air conditioning run but not cool?
It can be anything from a dirty filter to a refrigerant leak. Diagnosis confirms the cause and you get a fixed price before the repair.
Is the equipment covered by a warranty?
The manufacturer’s warranty, on the manufacturer’s terms. Terms differ by brand, and we set them out on your quote.
My air con is showing an error code. What should I do?
An error code points us in the right direction, but testing confirms the cause. Write down the code and turn the unit off if it has stopped, then call 07833 053749.
Can you look at a system you didn’t fit?
Yes. We start with a proper look and tell you honestly what we find, including any issues with how it was fitted. Any work is priced before it goes ahead.
What we are called out for in Langley Bottom
When the fan runs but the air is not cold, there are some common causes: 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. Diagnosis narrows it down.
The things we’re asked about most include:
- A suspected refrigerant leak
- A unit that barely blows any air
- A system that will not switch on
If a system fails at a school such as The Thomas Alleyne School, our 24/7 line takes the call, and planned repairs can wait for the holidays.
What your quote should include
- Whether they looked at the job before pricing it
- What’s in the price and what isn’t
- Whether the quote shows VAT clearly
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 the work itself, and finally everything is tested, recorded and explained. The middle part takes longest, and that takes anything from an hour or so to a full day, depending on the fault and the parts. Work in Langley Bottom is booked in advance at a time that suits you.
- Tell us the make, the symptoms and any error code, and send a photo of the display if you can.
- At the property, readings and tests narrow the problem down to its cause.
- Once the cause is found, we explain it and fix the price for the repair.
- 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.
Preparing for the visit
- Plan for pets to be kept clear during the visit
- Mention any parking restrictions near the property
- Let us know where the consumer unit is

Air conditioning repair around Langley Bottom
On the National Heritage List, around 8 entries fall within 0.5 miles of the middle of Langley Bottom; Dyes Farmhouse (grade II*) is one. Day-to-day work on an existing system is not affected; a replacement outdoor unit on a protected building might be. The last census (2021) found about 40% of households in terraced houses. Terraced homes rarely have side access, so say whether we reach the back through the house, a garage or a rear lane.
A photo of the error code and the unit’s rating label helps us plan the repair.
