What a repair looks like in Mortlake
The East Sheen Avenue Conservation Area is within about a third of a mile of the centre of Mortlake. There are 19 conservation areas within a mile of the centre of Mortlake. Historic England lists about 23 buildings and structures within half a mile of the centre of Mortlake, including Parish Church of St Mary (grade II*). That only matters for replacements, where a new outdoor unit on a protected building can need consent. About 58% of homes across Mortlake and its surrounding area were built before 1919, according to the Valuation Office Agency’s council tax figures. Tell us where your outdoor unit is and how to reach it, so we can plan the visit. In London, access to outdoor units on roofs and balconies can need planning, so tell us how to reach yours.
Schools such as Thomson House School can report a fault on the 24/7 line and have non-urgent work done out of term.

Air conditioning repair in Mortlake
A symptom is only a clue: warm air, drips and error codes can each have several causes. A unit blowing warm air might have a blocked filter, a failed sensor, a fault on the circuit board or a refrigerant leak, which is why diagnosis comes first. The work covers VRF systems, wall-mounted split systems and ducted systems, and common reasons people get in touch are water dripping from the indoor unit and weak airflow from the indoor unit.
In a managed building in Mortlake, the repair may need booking through the agent or building manager, so tell us who controls access. Outdoor units on roofs may need a key, a permit or an escort, which is worth sorting before the visit.
Some manufacturers make regular servicing by a qualified engineer a condition of their warranty. If that applies to your system, booking the service on time keeps the record straight, and every service is written up.

After we have gone
Simple habits make a real difference. We recommend:
- Turn the system off if it’s dripping water
- Send us a photo of any code on the display
- Let any ice thaw before the engineer arrives
Where a repair isn’t worth doing, we say so, and explain why. If replacement is the better option, we can quote for it on the same visit.
Use the system sensibly. Choose the right mode and a moderate set temperature, and keep doors and windows closed while it runs, so it isn’t running flat out all day.
What we do, step by step
Testing is the last part of the visit wherever the system can be switched on. Then we show you what we have done and answer any questions, and anything that needs a follow-up is pointed out there and then. All told, the work takes as long as the fault needs, from a quick fix to a return visit for parts. Some blocks in Mortlake need contractor details in advance, so tell us what your building needs.
- You tell us the symptoms, the make and any error code.
- On the diagnosis visit, we test the electrics, airflow, drain and refrigerant.
- The fault is explained simply and the repair priced up front.
- With your go-ahead, we carry out the repair, recording any refrigerant work.
- It’s tested running, and the write-up is left with you.
Preparing for the visit
- Unlock any gate, garage or side passage we need
- Let us know where the consumer unit is
- Tell us about access, such as roof hatches, high walls or locked plant areas

How the job changes from property to property
Multi-split systems
With several pipe runs, finding a leak on a multi-split takes method. We test each run to find it before the system is repaired, tested and recharged.
Ducted and cassette systems
If water is coming through the ceiling, switch the unit off and call us. A failed pump, a blocked drain or an overflowing tray is typically behind it and the diagnosis covers each of them.
Signs you need air conditioning repair in Mortlake
Ice on the pipework or the indoor coil is a symptom, not the fault. Low airflow from blocked filters or a failing fan, or low refrigerant from a leak, are the common causes. Turn it off and let the ice melt, then call us.
The things we are asked about most are:
- A system that won’t switch on
- Frost on the pipework
- A system that needs topping up again
Near Mortlake station, as anywhere, a photo of the error code on the controller is the quickest way to start a repair.
Questions to ask before you book
- If the quote is based on a survey, pictures or a diagnosis
- Which brand and model they’re proposing, and why
- What the manufacturer’s warranty covers and for how long

My air con is showing an error code. What should I do?
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.
Why is my air conditioning blowing warm air?
It could be a dirty filter, the wrong settings, a blocked outdoor unit, a sensor or board fault, or a refrigerant leak. Start by checking the filter and the mode, then call 07833 053749 or drop us a line if it’s still not cooling.
