About our air conditioning repair in Welling

Refrigerant doesn’t get used up, so a low charge means a leak somewhere. Simply adding gas means it will leak away again. We find and fix the leak, pressure test, evacuate and recharge to the manufacturer’s charge and write it up in the F-Gas records. If you’re dealing with a system that won’t switch on and rattling, buzzing or grinding noises, we can sort it out.

In a London area like Welling, a lot of the systems we repair serve flats and small offices, with outdoor units on balconies, rear walls or flat roofs. Telling us where the outdoor unit is and how we reach it saves time on the visit.

If a fault appears while the equipment is under the manufacturer’s warranty, tell us the make, model and installation date. We will tell you how the manufacturer’s warranty is likely to apply before any chargeable work goes ahead.

When air con fails in Welling

Danson Park Mansion, listed at grade I, is one of roughly 3 protected buildings and structures in the half-mile around Welling’s centre. Day-to-day work on an existing system isn’t affected; a replacement outdoor unit on a protected building might be. VOA council tax data show about 75% of homes in and around Welling date from 1919 to 1939, and Census 2021 figures found about 71% of households in detached or semi-detached houses. Access to the outdoor unit is the one detail that most changes how a visit is planned. London repairs often depend on reaching the outdoor unit, so access details help us plan.

For a school like Danson Primary School, urgent repairs can be booked right away and bigger work in the holidays.

What the work involves, system by system

Wall-mounted split systems

The single split is the most common system we’re called to. Drains, coils, fans, sensors and leaks account for many of the faults and the diagnosis starts with the fault code and the symptoms.

Refrigerant leaks

A low refrigerant charge always means a leak. The leak is found and fixed, then the circuit is tested, evacuated and recharged, and the work is recorded in the F-Gas records.

Questions from Welling

Is Welling in your area for air conditioning repair?

Yes. We work across London and the South East from our base in East Grinstead, and Welling is part of that. Just call us on 07833 053749 or use the quote form with a few details.

Who do I call if my air conditioning fails in Welling out of hours?

Yes: ring the emergency line, day or night, from anywhere in Welling. A diagnosis call-out starts from £75 + VAT, and knowing the brand and the symptoms helps us plan it.

What causes water to leak from an air conditioning unit?

Most leaks come from a blocked drain, a failed pump or a unit that has dropped out of level. Ice on the coil from low airflow or low refrigerant can also melt and drip. Turn it off and give us a ring on 07833 053749.

Can I fit air conditioning or a heat pump myself?

Anything that involves the refrigerant needs an F-Gas qualified engineer from a certified company. That’s a legal requirement, and it also matters for the manufacturer’s warranty. We can quote for the whole job, from supply to commissioning.

Do you work on systems someone else installed?

Yes. We work on systems fitted by other installers as well as our own, on all the main brands. Send us the make and model, and any records you have.

How soon will you get back to me?

We reply to enquiries the same working day. For a breakdown that cannot wait, call our 24/7 emergency line.

How long will you be on site?

That depends on what’s involved, but as a guide it takes as long as the fault needs, from a quick fix to a return visit for parts. We will confirm it with the quote.

How the visit works

Each visit follows the same order: agree the plan on site, put the dust sheets down, carry out the job, test what we have done and explain it all to you. On site, the work takes an hour or two to diagnose most faults, with the repair time depending on what we find. If your building in Welling has a managing agent, a concierge or sign-in rules, mention them when you book.

  1. Describe the problem and the brand, and mention any code on the display.
  2. A diagnosis visit finds the cause with proper tests.
  3. We explain the cause in plain English and give you a fixed price.
  4. With your go-ahead, we carry out the repair, recording any refrigerant work.
  5. It’s tested running, and the write-up is left with you.

Preparing for the visit

  • Plan for pets to be kept clear during the visit
  • Dig out any previous service or F-Gas records
  • Unlock any gate, garage or side passage we need

Leave it or put it right?

If the system may still be under the manufacturer’s warranty, report the fault early. Tell us the make, model and install date, and we will explain how the manufacturer’s warranty is likely to apply before any chargeable work. Hot weather is when everyone in London wants air conditioning, so it’s easier to plan the work in Welling early.

Leaving a fault or an overdue service rarely makes the work cheaper. Faults and wear in a system tend to grow, and a struggling system uses more electricity to do less. If you are unsure, give us a ring on 07833 053749 for straight advice and a fixed price.

Why book with us

  • Warranty terms set out brand by brand
  • A 24/7 emergency line

  • F-Gas company certification

Common problems we fix in Welling

Ice on the pipework or the indoor coil is a symptom, not the fault. It usually points to poor airflow, such as a clogged filter or a fan problem, or to a refrigerant leak. Switch the system off and let it thaw before calling us.

Most people get in touch when they notice something like this:

  • A fault code on the display
  • Air conditioning running but not cooling
  • Ice forming on the indoor unit or pipes

For a home or office near Welling station, tell us the make, model and error code when you call, so we can plan the repair.

Before booking anyone

  • Whether the manufacturer’s warranty depends on regular servicing
  • What paperwork you’ll receive afterwards
  • Whether a new circuit is included and who certifies it
