Air conditioning repair for homes and businesses in Lewisham
Faults on all the leading makes are part of our everyday work, from Mitsubishi Electric, Daikin and Fujitsu to Panasonic, Toshiba, LG, Samsung, Mitsubishi Heavy Industries and Hitachi. Systems fitted by other installers are fine too, so tell us the make and model if you know it. The work covers ceiling cassettes, ducted systems and multi-split systems, and people most often call us about a unit that won’t start and a system that needs topping up again.
London systems in Lewisham often run long hours in summer, which is when weak cooling, leaks and error codes tend to appear. The error code on the display, the make and the model are the most useful things to send us.
Warranty on the equipment is the manufacturer’s own, on the manufacturer’s terms, and we set them out on your quote. Each brand sets its own conditions, and we’re happy to talk you through them.

System by system
Refrigerant leaks
A low refrigerant charge always means a leak. We find it, repair it, pressure test the circuit, evacuate it and recharge to the manufacturer’s charge and every step is recorded.
Circuit boards and sensors
We test sensors and boards before replacing them, so you don’t pay for a part that wasn’t the problem. Parts may need ordering and we’ll explain any wait.

What we do, step by step
The visit goes in the diary at a time that works for you, and we let you know if plans need to move. When we arrive, we check the job against the survey or the pictures you sent. Anything unexpected is raised with you before we go further. From there, the work takes a single visit for many faults, while some repairs need a second visit once parts arrive. Some blocks in Lewisham need contractor details in advance, so tell us what your building needs.
- Tell us the make, the symptoms and any error code, and send a photo of the display if you can.
- We diagnose on site, checking the codes, electrics, airflow, drain and refrigerant pressures.
- You get a plain explanation of the fault and a fixed price for putting it right.
- We repair the fault, and where refrigerant is involved, the leak is found and fixed before recharging.
- We run the system, check it’s working properly and note anything else that needs attention.
Getting ready for the visit
- Make sure someone can let us in at the agreed time
- Make sure we can reach the consumer unit or fuse board
- Mention any managing agent or landlord rules we need to follow
Getting a price
Every quote starts with a look at the job, either on a site survey or, for simple jobs, from your pictures and details. After that, we send a fixed price before any work starts.
Advice
What you can do yourself, and what needs us
Refrigerant is off limits for anyone without the right qualifications. Under the F-gas rules, engineers need their own qualifications and the company must be certified, and refrigerant lines can cause cold burns. A suspected leak is our job, not yours.
Some faults have simple causes you can check first: is the system in the right mode, is the set temperature sensible, are the remote’s batteries working and has the breaker tripped. If the breaker trips a second time, leave it off and phone us on 07833 053749 or email us.
What a repair looks like in Lewisham
About 37% of homes in the Lewisham area were built before 1919, according to the Valuation Office Agency’s council tax figures, and Census 2021 figures found about 69% of households live in flats. If you live in a flat, mention any roof hatch, balcony or managing agent we will need to get to the outdoor unit. In London buildings, outdoor units can be on roofs or in light wells, so let us know where yours is. Lewisham’s centre is no more than about a third of a mile from the Mercia Grove Conservation Area. Draw a one-mile circle round the middle of Lewisham and it takes in 12 conservation areas. On the National Heritage List, around 45 entries fall within 0.5 miles of the middle of Lewisham; St Mary's Vicarage (grade II*) is one. Day-to-day work on an existing system isn’t affected; a replacement outdoor unit on a protected building might be.

Common questions in Lewisham
Is there an emergency air con repair line for Lewisham?
The emergency line is open around the clock, and Lewisham is one of the places it covers. A diagnosis call-out starts from £75 + VAT, and knowing the brand and the symptoms helps us plan it.
Do you cover Lewisham for air conditioning repair?
Yes, Lewisham is within the area we cover. To start, phone us on 07833 053749, or email if that’s easier with a few pictures.
What does F-Gas certified mean?
F-Gas certification shows a company is approved to work on equipment containing fluorinated gases, such as the refrigerant in air conditioning and heat pumps. In Great Britain, that certification is a legal requirement, not an optional extra, and we hold it.
Why does my air conditioning run but not cool?
There are several possible causes, from simple to serious. Diagnosis confirms the cause and you get a fixed price before the repair.
Whose job is it to check the system for leaks?
Whoever operates the equipment, together with the technicians who service it. 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 can tell you which band your system falls into.
Do you offer maintenance contracts?
Yes. Send details of the systems and how they’re used and we will propose a schedule and quote for it. Leak checks required by the F-gas rules can be built in for larger systems.
Is the equipment covered by a warranty?
Warranty is the manufacturer’s own, on its terms. Terms differ by brand, and we set them out on your quote.
Landlords, agents and facilities managers
Under the GB F-gas rules, responsibility for leak checks is shared between whoever operates the equipment and the engineers who work on it. Where a building is let or managed, the lease or contract should make clear who looks after the system and we’re happy to deal with whoever it is.
For anyone managing more than one building, we can quote and plan the work across all of them. Every address has its own paperwork, so each one has its own history.
