About our air conditioning repair in Wandsworth
Any repair we carry out in Wandsworth starts the same way: the engineer reads the fault codes and checks the electrics, the airflow, the condensate drain and the refrigerant pressures and temperatures. After that, you get a plain explanation and a fixed price for the repair. Common call-outs are for a system that needs topping up again and water dripping from the indoor unit, on wall-mounted split systems, heat pumps and ducted systems.
Air conditioning repairs in Wandsworth are often in flats, offices and shops, where the outdoor unit may be on a balcony, a rear wall or the roof. Knowing where the outdoor unit sits, and how to get to it, helps us plan the repair.
Looking after a system is mostly common sense: keep the outdoor unit clear, follow the manufacturer’s guidance on cleaning and book a service at the interval they recommend. It also keeps you on the right side of any warranty terms that ask for servicing.

Landlords, agents and facilities managers
Where a tenant occupies the property but the landlord owns the system, the lease or tenancy agreement normally sets out who maintains what. We can quote either party, and the paperwork can go to both.
Under the GB F-gas rules, responsibility for leak checks is shared between whoever operates the equipment and the engineers who work on it. In a let or managed building, it’s worth agreeing who that operator is and we’re happy to deal with whoever it is.
Wandsworth questions
Do you cover Wandsworth for emergency air conditioning repairs?
The emergency line is open around the clock, and Wandsworth is one of the places it covers. Have the make, model and error code ready, and we’ll talk you through what happens next.
Can I get a fixed-price quote for air conditioning repair in Wandsworth?
The easiest way is to call us on 07833 053749 or use the quote form with a few details and pictures. We reply the same working day, and the quote is fixed before any work starts.
Why is there ice on my air conditioning pipes?
It typically points to poor airflow or a refrigerant leak. Blocked filters, a failing fan or a leak are the common causes. Turn it off, let the ice melt and call 07833 053749 or fill in the contact form.
Can landlords and managing agents book you?
Yes. From one rented home to commercial buildings, the approach is the same: a look first, a fixed-price quote and written records.
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 are happy to quote for the full job, supply to commissioning.
Why use an F-Gas certified company?
Certification shows a business is approved to work on systems that hold F gas refrigerant. That isn’t optional: it’s required by law, and AirCon Doctor is certified.
Why is water dripping from my indoor 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. Switch the unit off and phone us on 07833 053749.

What happens on the day
Where something has to be switched off during the work, we agree it with you first so it doesn’t catch you out. For businesses, we can typically work room by room or zone by zone. On site, it takes a single visit for many faults, while some repairs need a second visit once parts arrive. Pictures of the space and the outside wall help us plan the work in Wandsworth.
- First, a few questions by phone or email about the brand, the fault and anything shown on the controller.
- On the diagnosis visit, the engineer tests the system rather than guessing.
- We explain the cause and give you a fixed price for the repair before any work goes ahead.
- The repair is carried out, and any refrigerant work is leak tested and recorded.
- Finally the system is tested in operation and you get a note of the fault and the fix.
How to prepare
- Let us know where we can park and unload
- Dig out any previous service or F-Gas records
- Unlock any gate, garage or side passage we need
How to get a quote
To help us quote: where the property is and what kind of building it is, pictures of the rooms or units, the make and model of any existing system and anything you’ve noticed, such as an error code or a noise. Once you have those, call 07833 053749.

Why deal with it now?
A struggling system costs more to run. A dirty coil, a blocked filter or a low refrigerant charge all make the system work harder for less cooling, and the extra strain can shorten the life of the compressor. Consents in London blocks can take time, which is another reason to plan the job in Wandsworth early.
Every job is different, so we price each one individually. The equipment, how we reach it, the route between units and the work needed all make a difference.

Honest limits
An honest diagnosis matters more to us than a booking, so here’s what this work cannot put right:
- A unit that was never big enough for the room
- A power cut or a fault on the incoming supply to the building (that is for the network operator)
- A discontinued model with no parts available
Not sure which it is? You can phone 07833 053749 or use the quote form and we will tell you honestly before you book.
