Air conditioning repair in Charlton

What happens on the day

The first job on site is protection: sheets over the floor and any furniture nearby and nothing is moved without asking you. Then the electrics are made safe and the work begins. It takes as long as the fault needs, from a quick fix to a return visit for parts, and we tidy up before we leave. Photos of the room and the outside wall help us plan a job near Charlton.

  1. You describe the fault, the make and any error code, ideally with a photo.
  2. The engineer reads the fault codes and checks the electrics, airflow, drain and refrigerant circuit.
  3. You get a plain explanation of the fault and a fixed price for putting it right.
  4. The repair is carried out, and any refrigerant work is leak tested and recorded.
  5. Before leaving, we run it through its modes and write up what was found and done.

Preparing for the visit

  • Unlock any gate, garage or side passage we need
  • Have the make and model of any existing unit to hand
  • Let us know where we can park and unload

Advice

How we handle air conditioning repair in Charlton

A sealed system shouldn’t lose refrigerant, so if it’s low, there’s a leak. 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. If the problem is a unit blowing warm air and a system that won’t switch on, we can help.

Around Charlton, most of our repairs are in homes, with some small businesses. What you tell us about the fault shapes the visit, so describe what it’s doing and send a photo of any error code.

Any work on the refrigerant circuit is recorded: the work carried out, the refrigerant involved and the quantities. Keep the records with the manual and the warranty documents, ready for the next service or a warranty query.

Why act early in Charlton

For a faulty system in Charlton, an early diagnosis is the sensible first step. It takes a single visit for many faults, while some repairs need a second visit once parts arrive, and you get a fixed price for the repair before any work goes ahead, and our emergency line runs 24/7. Waiting rarely makes an air conditioning problem smaller.

Our prices page shows typical ranges, but your price depends on the job in front of us. Call for a fixed-price quote, and we will explain what it covers.

Why book with us

  • Warranty terms set out brand by brand
  • An F-Gas certified company, as the law requires
  • Diagnosis first, then a fixed price
  • Enquiries answered the same working day

Keeping the system healthy

Systems last better with the right care. Here’s what we suggest:

  • Stop the unit if water is coming through a ceiling
  • Turn it off and let ice clear before the visit
  • Keep to the service interval the manufacturer recommends

Where a repair needs parts, we explain what’s been ordered and agree the return visit with you. Parts lead times depend on the supplier and we will keep you updated.

Don’t ignore early signs. A drip, a new noise, a weaker airflow or an occasional error code is often the first sign of a fault, and early diagnosis normally means a smaller repair.

Air conditioning repair in Charlton: the local picture

Valuation Office Agency council tax records show about 31% of homes in and around Charlton were built in 2000 or later. Access to the outdoor unit is the one detail that most changes how a visit is planned. Draw a one-mile circle round the middle of Charlton and it takes in 2 conservation areas. Yew Tree Cottage, listed at grade II, is one of roughly 34 protected buildings and structures in the half-mile around Charlton’s centre. That only matters for replacements, where a new outdoor unit on a protected building can need consent.

For a school like Charlton Primary School, urgent repairs can be booked straight away and bigger work in the holidays. If the display shows a code, write it down: it helps narrow down the fault.

  • The condition of any existing system

Height, access and the distance between the indoor and outdoor units all affect the cost. Each of those is built into the quote, and the price is fixed before work begins.

Charlton: your questions answered

Do you cover Charlton for air conditioning repair?

Yes. We work across London and the South East from our base in East Grinstead, and Charlton is part of that. Get in touch with the details and we reply the same working day.

Is Charlton within the area you cover?

We do. Villages and hamlets get the same service as the bigger towns. Send a few details and pictures, and we reply the same working day.

Which accreditations do you hold?

F-Gas certified, NICEIC approved and MCS certified for heat pumps, plus Checkatrade membership. Engineers who handle refrigerant hold their own F-gas qualifications as well.

Can I fit air conditioning or a heat pump myself?

The refrigerant side has to be done by a qualified engineer working for an F-Gas certified company. That’s the law, not just our preference, and manufacturers expect it for their warranty too. We can quote for the whole job, from supply to commissioning.

Why is my air conditioning showing a fault code?

Each manufacturer uses its own codes, and one code can have more than one cause. Send us a photo of the display with the make and model and we will test the system to confirm the cause.

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.

Is there a survey before the work?

Yes. We always look before we price, either on a site survey or from pictures and details for simple jobs. A fixed-price quote follows.

From one of our customers

“Very professional from the initial survey through to installation. The engineer explained everything clearly and the quote was exactly what we paid. Would not hesitate to recommend AirCon Doctor.”
