How the visit works
Our engineers arrive at the time agreed with you and check the plan with you first. Floors and furniture near the work are covered with dust sheets, and the electrics are made safe before any panel comes off. The work itself takes a single visit for many faults, while some repairs need a second visit once parts arrive. Parking bays, permits and roof or balcony access are the first things we ask about in Erith.
- Describe the problem and the brand, and mention any code on the display.
- A diagnosis visit finds the cause with proper tests.
- We explain the cause in plain English and give you a fixed price.
- Once you are happy, the repair is done and any refrigerant work recorded.
- We test the system in operation and leave you a note of the fault and the fix.
Before we arrive
- Unlock any gate, garage or side passage we need
- Clear the space around the indoor unit, or where it will go
- Dig out any previous service or F-Gas records

How we handle air conditioning repair in Erith
Not sure whether it’s worth calling an engineer? A quick check of the filter, settings and remote can rule out the simple causes, then call 07833 053749, or email if that’s easier if the problem is still there. You’ll hear back from us the same working day. If you are dealing with a suspected refrigerant leak and a unit blowing warm air, we can sort it out.
Many buildings in Erith have a managing agent or security desk, so let us know who needs to know we’re coming. Outdoor units on roofs may need a key, a permit or an escort, which is worth sorting before the visit.
For a fault on a system that may still be under warranty, send 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.

Air conditioning repair in Erith: the local picture
London repairs often depend on reaching the outdoor unit, so access details help us plan. Roughly a third of a mile or less from central Erith, you reach the Lesney Park Road Conservation Area. Draw a one-mile circle round the middle of Erith and it takes in 4 conservation areas. Listed buildings are part of the picture here: about 5 within half a mile of the centre, such as Christ Church (grade II*). If a repair turns into a replacement on a listed building or in a conservation area, we check the planning position before changing the outdoor unit.
If a system fails at a school such as Christ Church (Erith) CofE Primary School, our 24/7 line takes the call, and planned repairs can wait for the holidays.
Erith is about 3 miles north-west of Dartford, in Greater London. From the centre of Erith to the outskirts, our engineers cover air conditioning repair, from a single room to a whole building. Erith is one of 764 towns, villages and districts in Greater London we cover for homes and businesses. Bromley, roughly 9 miles off, has its own page on this site.
The closest recent job we can point to from Erith was on Station Road, Orpington (BR6), about 7 miles south-west: installing three Daikin cassette units in the main office area and a wall-mounted unit in the client meeting room.

FAQs for Erith
Do you cover Erith for air conditioning repair?
We do: Erith falls inside our working area. Just phone us on 07833 053749 or send an email with a few details.
Is there an emergency air con repair line for Erith?
The emergency line is open around the clock, and Erith is one of the places it covers. Have the make, model and error code ready, and we will talk you through what happens next.
How quickly will you reply?
You will hear from us the same working day. For a breakdown that cannot wait, call our 24/7 emergency line.
Why is my air conditioning leaking water?
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 07833 053749 or use the quote form.
Which brands do you work with?
Mitsubishi Electric, Daikin, Fujitsu, Panasonic, Toshiba, LG, Samsung, Mitsubishi Heavy Industries, Hitachi and others. For new systems, we recommend a brand and model to suit the job and tell you why.
What can I do with an old R22 system?
Replacement is normally the better answer. New R22 cannot be used to service systems, and parts for older units are getting harder to find, so a new system on a modern refrigerant is usually the better investment.
Will I get records for the system?
Yes. It’s your proof of what was done: a dated note of the work, with refrigerant details where they apply.
How the job changes from property to property
Wall-mounted split systems
Wall-mounted splits are the systems we repair most often. Drains, coils, fans, sensors and leaks account for many of the faults, and most are diagnosed on the first visit.
Circuit boards and sensors
Circuit boards and temperature sensors control how the system runs. Sensor faults can stop the system or confuse it, and boards can fail after a power surge or with age.
Do you need air conditioning repair in Erith?
Rattles, buzzes and grinding sounds tend to be mechanical. Worn fan bearings, loose panels, debris in the outdoor fan or pipework vibrating against the building are common, and some noises point to the compressor.
Any of these is worth a proper look:
- A unit that barely blows any air
- A flashing light and a system that won’t run
- A noisy indoor or outdoor unit
Shops and offices around Erith station often can’t wait for cooling to come back, which is what the 24/7 line is for.
What your quote should include
- How extra work would be agreed if they find something unexpected
- Proof of F-Gas company certification
- Whether the manufacturer’s warranty depends on regular servicing

Aftercare tips
Think of this as the after-treatment advice, short and simple:
- Check the settings and the remote’s batteries first
- If there’s ice on the pipes, switch off and let it melt
- Never add refrigerant yourself or let anyone top up without finding the leak
Once the fault is fixed, we test the system in operation. We check it’s cooling or heating as it should and that the fault hasn’t left anything else behind, and we tell you about anything we noticed.
Use the system sensibly. Moderate settings and a closed room mean less strain, so it isn’t running flat out all day.
From one of our customers
“Excellent service from start to finish. Two wall-mounted units installed in our home. Clean, tidy work: they protected all the floors and left no mess. The systems work brilliantly. Would highly recommend.”
