Air conditioning repair in Deptford, Greater London
Need air conditioning repair in Deptford? We look at the job first, give you a fixed-price quote and do the work at a time that suits you, finishing with proper records.
- A system that needs topping up again
- A flashing light and a system that will not run
- Water leaking from the unit or through the ceiling
After we have gone
So the system stays in good health:
- Let any ice thaw before the engineer arrives
- Check the settings and the remote’s batteries first
- Keep to the service interval the manufacturer recommends
After the repair, the system is run and checked in every mode it has. We confirm it’s working properly and look for anything else that needs attention, and we tell you about anything we noticed.
Clean the filters regularly. Blocked filters cut airflow, which can lead to poor cooling, ice on the coil and drips and the manual shows how to clean them.
Air conditioning repair in Deptford, done properly
Older systems raise a fair question: repair or replace?. A fan fault on an older unit can be worth fixing, while a compressor failure may tip the balance. You get an honest view based on the fault, the parts, the refrigerant and the room. We are often asked to deal with an error code or flashing light on the unit and a unit that won’t start, on multi-split systems, ducted systems and ceiling cassettes.
Air conditioning repairs in Deptford are often in flats, offices and shops, 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.
Think of the paperwork as the system’s health record: a dated account of the work and the readings we took. If anything goes wrong later, it helps the next engineer and the manufacturer, so keep it safe.

Different systems, different jobs
Ducted and cassette systems
Water through a ceiling below a cassette or ducted unit needs prompt attention. A failed pump, a blocked drain or an overflowing tray is normally behind it, and we check all three.
Condensate drains and pumps
We clear the drain, test the pump and check the fall until the condensate runs away properly. If a pump has failed, we replace it and tested before we go.

What air conditioning will not do
An honest diagnosis matters more to us than a booking, so here’s what this work can’t put right:
- A refrigerant fault on an R22 system (new R22 cannot be used for servicing, so replacement is usually the answer)
- A building problem rather than a system fault
- An old system with obsolete parts
If you’re not sure, just call 07833 053749 or drop us a line and we will give you a straight answer before you book.
Parts of the system we cover
- Wall-mounted split systems
- Heat pumps
- Multi-split systems
- Ceiling cassettes
- VRF systems
- Ducted systems
The process
We book the visit for a day and time that suit you, and we keep you posted if anything changes. When we arrive, we check the job against the survey or the photos you sent. Anything unexpected is raised with you before we go further. After that, it takes an hour or two to diagnose most faults, with the repair time depending on what we find. For a job in Deptford, tell us about parking, permits and access to the building when you get in touch.
- 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.
- Once the cause is found, we explain it and fix the price for the repair.
- With your agreement the part is replaced or the fault put right, and refrigerant work goes in the F-Gas log.
- We run the system, check it’s working properly and note anything else that needs attention.
How to prepare
- Mention any managing agent or landlord rules we need to follow
- Clear the space around the indoor unit, or where it will go
- Keep pets and children away from the work area
Getting a price
Quoting starts with a diagnosis, from a site survey or, where the job is straightforward, from pictures and measurements. After that, we send a fixed price before any work starts.

Deptford: your questions answered
Is there an emergency air con repair line for Deptford?
The emergency line is open around the clock, and Deptford is one of the places it covers. Say what the system is doing and whether it shows a code, and we will advise on the next step.
What’s the best way to get a price for air conditioning repair in Deptford?
Send us photos of the room or the system and a few details about the property. We reply the same working day, and the quote is fixed before any work starts.
What warranty do I get?
It’s the manufacturer’s, and the terms are theirs. Some terms depend on regular servicing by a qualified engineer so it’s worth keeping the service records.
Can you look at a system you didn’t fit?
Yes. We work on systems fitted by other installers as well as our own from all the leading brands. Send us the make and model, and any records you have.
Why is my air conditioning showing a fault code?
An error code points us in the right direction, but testing confirms the cause. Write down the code and turn the unit off if it has stopped, and phone us on 07833 053749 or drop us a line.
Will skipping a service affect the warranty?
Check the manufacturer’s terms. Some warranty terms require the system to be serviced regularly by a qualified engineer, so check the terms or ask us. Either way, keep a record of every service.
My system uses R410A. Can it still be repaired?
Yes. Any leak is repaired before recharging, and the work is recorded, and we tell you honestly whether a repair is worth it on an older system.
From one of our customers
“Office air con broke down in the July heatwave. Called at 8am, engineer was here by noon and fixed within 2 hours. Brilliant emergency response. They now hold the service contract for the whole building.”
