Air conditioning repair in South Darenth
Wondering whether the fault is something simple? A quick check of the filter, settings and remote can rule out the simple causes, then give us a ring on 07833 053749, or email if that’s easier if the problem is still there. We reply to enquiries the same working day. The work covers multi-split systems, heat pumps and ceiling cassettes, and the jobs we see most are weak airflow from the indoor unit and a flashing light and a system that won’t run.
A visit to South Darenth is planned so we can usually finish in one go, unless a part has to come from the manufacturer.
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.

When to call us in South Darenth
Most indoor unit leaks come back to the condensate. The drain may be blocked or kinked, the condensate pump may have failed, or the unit may not be level, and ice on the coil that melts can drip too.
Most people get in touch after spotting one of these:
- Rattling, buzzing or grinding noises
- A system that needs topping up again
- Water leaking from the unit or through the ceiling
When cooling fails at a school like Horton Kirby Church of England Primary School, we can time non-urgent repair work around lessons.

Other services in South Darenth
For landlords and property managers
Larger air conditioning systems in buildings need more than servicing: a TM44 inspection by an accredited energy assessor is required at least every 5 years for systems over 12 kW. We can arrange it, prepare the system for it and fix what it finds.
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 can work for either side.
Common questions in South Darenth
Do you cover smaller places like South Darenth?
Yes, smaller places are covered as well as towns. We are based in East Grinstead and plan each visit so the job can be finished in one trip where possible.
Do you cover South Darenth for emergency air conditioning repairs?
Yes. Our 24/7 emergency line covers South Darenth. Say what the system is doing and whether it shows a code, and we will advise on the next step.
Why does F-Gas certification matter?
For refrigerant work, both the engineer and the company need the right F-gas credentials. It’s worth checking before booking, and we are happy to show ours.
Why is my air conditioning leaking water?
The condensate drain or pump is the usual cause: a blocked pipe, a kinked hose or a failed pump. Switch the unit off to avoid water damage, then call us.
Whose job is it to check the system for leaks?
The operator of the equipment, working with qualified engineers. Systems below 5 tCO2e fall outside the set leak check intervals, while larger ones need checks at least every 12 months, or every 6 months from 50 tCO2e. We’ll work out which band applies to yours.
Why is my air conditioning showing a fault code?
An error code points us in the right direction, but it is not the whole answer. Write down the code and turn the unit off if it has stopped, then call 07833 053749 or use the quote form.
What can I do with an old R22 system?
Servicing with new R22 isn’t allowed, because it depletes the ozone layer. Some non-refrigerant faults can be repaired if parts are available, but a leak typically makes replacement the sensible route. We will set out the options and quote for a replacement where it makes sense.
How the visit works
Our engineers bring the tools, gauges and access equipment the job needs. You only need to give us clear access to the units, or their planned positions, and to the fuse board. The visit takes a single visit for many faults, while some repairs need a second visit once parts arrive. Photos of the existing unit help with repairs and servicing in South Darenth.
- First the diagnosis: fault codes read, electrics and airflow checked, drain and refrigerant tested.
- Then the prescription: what’s wrong and what it will cost to put right.
- Where a repair does not make sense, you’ll hear it from us, with the alternatives.
- Then the fix, with leaks repaired before any refrigerant is added.
- The sign-off: the system tested in operation and the work recorded.
Getting ready for the visit
- Give us access to the outside wall, roof or yard where the outdoor unit sits
- Clear access to the fuse board
