About our air conditioning repair in Eltham
Age alone doesn’t decide whether a repair is worth it. A system with a failed fan motor may be well worth repairing, while one with a failed compressor might not be. You get an honest view based on the fault, the parts, the refrigerant and the room. Common call-outs are for a flashing light and a system that won’t run and a noisy indoor or outdoor unit, across wall-mounted split systems, multi-split systems and ducted systems.
London systems in Eltham often run long hours in summer, and that’s when faults show: weak cooling, water leaks, error codes or a unit that won’t start. The error code on the display, the make and the model are the most useful things to send us.
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.

Air conditioning repair in Eltham: the local picture
Valuation Office Agency council tax records date about 40% of homes across Eltham and its surrounding area to the post-war years, 1945 to 1972, and Census 2021 figures found about 51% of households live in flats. Outdoor units serving flats can be awkward to reach, so let us know where yours is. In London, access to outdoor units on roofs and balconies can need planning, so tell us how to reach yours. Eltham’s centre falls inside a designated conservation area. Historic England lists about 40 buildings and structures within half a mile of the centre of Eltham, including Great Hall of Eltham Palace (grade I). We keep it in mind in case a new outdoor unit is ever needed, as protected buildings can need consent for that.
For a home or office near Mottingham station, tell us the make, model and error code when you call, so we can plan the repair. For a school like St Thomas More Catholic Comprehensive School, urgent repairs can be booked right away and bigger work in the holidays.

Questions from Eltham
What’s the best way to get a price for air conditioning repair in Eltham?
Use the quote form, or email, with a description of the job. Simple jobs can be priced from photos; otherwise we arrange a site survey and then give you a fixed-price quote.
Do you cover Eltham for air conditioning repair?
Yes. We work across London and the South East from our base in East Grinstead, and Eltham is part of that. Tell us a little about the job and we’ll take it from there.
How long does the work take?
That depends on what’s involved, but most of the time it takes a single visit for many faults, while some repairs need a second visit once parts arrive. We’ll confirm it with the quote.
What can I do with an old R22 system?
In most cases, we recommend replacement. R22 cannot be topped up with new gas, and parts for old models are scarce, so we will quote for a modern replacement and explain why.
Can we book visits on a schedule?
Yes. We offer maintenance contracts, set at the interval the system and the manufacturer’s terms need. Each visit is written up, with F-Gas records where refrigerant work is involved.
Who has to arrange F-Gas leak checks?
Responsibility is shared between the operator, usually whoever owns or controls the equipment, and the service technicians. The interval depends on the refrigerant charge, measured in tonnes of CO2 equivalent: at least every 12 months from 5 tCO2e, and every 6 months from 50 tCO2e.
How soon will you get back to me?
We reply to enquiries the same working day. If it’s an emergency, ring the 24/7 line instead.

Landlords, agents and facilities managers
Where a tenant occupies the property but the landlord owns the system, it’s worth checking the agreement for who looks after the system. We can quote either party, and the paperwork can go to both.
Facilities teams in offices, schools and public buildings book us too in Eltham and across Greater London. Work can be phased by floor, zone or building to keep disruption down.
Different systems, different jobs
Condensate drains and pumps
The condensate drain is behind most indoor unit leaks. Blockages, kinks and failed pumps are the usual causes, and a unit that is not level can spill water too.
Wall-mounted split systems
The single split is the most common system we’re called to. Drains, coils, fans, sensors and leaks account for many of the faults and the diagnosis starts with the fault code and the symptoms.
What happens on the day
Where something has to be switched off during the work, we agree it with you first so it does not catch you out. In a business, work can often be done one area at a time. The work takes anything from an hour or so to a full day, depending on the fault and the parts. Parking bays, permits and roof or balcony access are the first things we ask about in Eltham.
- We start with what the unit is doing, the make and any code.
- A diagnosis visit finds the cause with proper tests.
- You get the cause explained and a fixed price for the repair.
- Once you are happy, the repair is done and any refrigerant work recorded.
- The system is run and checked, and you get a written note of the repair.
How to prepare
- Mention any managing agent or landlord rules we need to follow
- Have the make and model of any existing unit to hand
- Arrange for someone to be there to let us in
Getting a price
Photos are the fastest route to a quote: the inside and outside of the property where the work is, plus the rating plate of any unit already there. Add the address and what you’d like done, and simple jobs can often be priced without a visit.

Why deal with it now?
Refrigerant supply is changing. R410A systems can still be repaired legally, though the GB phase-down is making R410A harder and dearer to buy, so for older systems we compare the cost of a repair with a replacement. Hot weather is when everyone in London wants air conditioning, so it’s easier to plan the work in Eltham early.
Putting the work off seldom saves money. Faults and wear in a system tend to grow, and a struggling system uses more electricity to do less. If you’re not sure what’s needed, call us on 07833 053749 or drop us a line and we’ll give you an honest view and a fixed price.
