About our air conditioning repair in Charlton
Older systems raise a fair question: repair or replace?. A system with a failed fan motor may be well worth repairing, while one with a failed compressor might not be. You get an honest view based on the fault, the parts, the refrigerant and the room. If the problem is water leaking from the unit or through the ceiling and a unit that won’t start, we can help.
Outdoor units in a place like Charlton can be near hedges and fields, so leaves, seeds and cobwebs on the coil are worth checking first.
Each manufacturer sets its own warranty period. For example, Daikin’s standard warranty on split air conditioning is 2 years, and its longer extensions apply to its air-to-water units only. For any other brand, we explain the manufacturer’s terms on your quote.

What owners can safely do
Write down what you notice: error codes, noises, drips, smells or a drop in performance. It helps us diagnose quickly, and a photo or a short video of the display is even better.
Don’t 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.
What we do, step by step
Everything the job needs comes with us, from tools and test equipment to ladders and dust sheets. You only need to give us clear access to the units, or their planned positions, and to the fuse board. The visit takes anything from an hour or so to a full day, depending on the fault and the parts. Photos of the room and the outside of the property help us plan a visit to Charlton.
- You tell us the symptoms, the make and any error code.
- The engineer diagnoses the fault on site, testing rather than guessing.
- You get the cause explained and a fixed price for the repair.
- With your go-ahead, we carry out the repair, recording any refrigerant work.
- The system is run and checked, and you get a written note of the repair.
How to prepare
- Let us know where we can park and unload
- Make sure we can reach the consumer unit or fuse board
- Mention any managing agent or landlord rules we need to follow

When something else is needed
To be straight with you, some problems need a different answer:
- A power cut or a fault on the incoming supply to the building (that is for the network operator)
- Cooling that falls short because the system is too small
- A room that overheats because of the building, such as a lack of shading or ventilation (the system may need help, not a repair)
If you are not sure, just ring us on 07833 053749 or fill in the contact form and we’ll give you a straight answer.

What a repair looks like in Charlton
About 49% of homes in the Charlton area date from 1945 to 1972, according to the Valuation Office Agency’s council tax figures.

When cooling fails at a school like Littleton CofE Infant School, we can time non-urgent repair work around lessons. Near Upper Halliford station, as anywhere, a photo of the error code on the controller is the quickest way to start a repair.

Charlton questions
Will you come out to Charlton?
Yes, smaller places are covered as well as towns. Send a few details and pictures, and we reply the same working day.
Is Charlton in your area for air conditioning repair?
We do: Charlton falls inside our working area. Tell us a little about the job and we will take it from there.
Why is there ice on my air conditioning pipes?
The coil gets too cold when air cannot move across it or when the refrigerant charge is low. A dirty filter is worth checking first and if that is not it, we will find the cause.
Why is my air conditioning leaking water?
Normally a blocked or kinked condensate drain, a failed condensate pump or a unit that isn’t level. Ice on the coil from low airflow or low refrigerant can also melt and drip. Switch the unit off and ring 07833 053749 or write to us at info@aircondoctor.co.uk.
Is there a survey before the work?
Yes. We always look before we price, either on a site survey or from photos and details for simple jobs. Then you get a fixed-price quote.
Do you provide F-Gas records?
Yes. Every visit is written up, and any work on the refrigerant circuit goes in the F-Gas records. File them with the system’s paperwork.
How much does an air conditioning repair cost?
It starts with a diagnosis call-out from £75 + VAT, followed by a fixed price for the repair. You decide before any repair work starts.
