Anything unexpected is raised with you before we go further. After that, it takes as long as the fault needs, from a quick fix to a return visit for parts. Send us a few phone pictures and we can often price a straightforward job in Earlsfield before visiting.

About our air conditioning repair in Earlsfield
Refrigerant doesn’t get used up, so a low charge means a leak somewhere. Simply adding gas means it will leak away again. We find and fix the leak, pressure test, evacuate and recharge to the manufacturer’s charge, then record it in the F-Gas records. We are often asked to deal with air conditioning running but not cooling and a fault code on the display, across ducted systems, heat pumps and ceiling cassettes.
In a London area like Earlsfield, a lot of the systems we repair serve flats and small offices, 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.
We’re an F-Gas certified company, NICEIC approved for electrical work, with MCS certification for heat pumps and Checkatrade membership. Our engineers hold the F-gas qualifications needed to work on refrigerant.

Common problems we fix in Earlsfield
A unit that runs but does not cool has a few usual suspects: dirty filters, wrong settings, a blocked outdoor unit, a sensor or board fault, or a refrigerant leak. Diagnosis narrows it down.
The things we’re asked about most are:
- A unit that won’t start
- A flashing light and a system that will not run
- A suspected refrigerant leak
Schools such as Beatrix Potter Primary School can report a fault on the 24/7 line and have non-urgent work done out of term.

Questions from Earlsfield
Do you cover Earlsfield for emergency air conditioning repairs?
The emergency line is open around the clock, and Earlsfield is one of the places it covers. Have the make, model and error code ready, and we will talk you through what happens next.
What’s the best way to get a price for air conditioning repair in Earlsfield?
Use the quote form, or email, with a description of the job. Where pictures are not enough, a survey comes first and the fixed-price quote follows.
Why isn’t my air con cooling?
It could be a dirty filter, the wrong settings, a blocked outdoor unit, a sensor or board fault, or a refrigerant leak. Start by checking the filter and the mode, then phone 07833 053749 or use the quote form if it’s still not cooling.
Can I do the refrigerant work myself?
No, not the refrigerant side. Under the F-gas rules, it must be done by qualified engineers from a certified company, and a new electrical circuit is notifiable building work unless a registered competent person does it.
My system uses R22. Can it be repaired?
Servicing with new R22 isn’t allowed, because it depletes the ozone layer. A fault that doesn’t involve the refrigerant may still be repairable, depending on parts, but a refrigerant leak normally means replacement. We explain the options and quote for a new system if that is the answer.
What accreditations do you have?
We hold F-Gas company certification, which the law requires for any business working on refrigerant. We are also NICEIC approved, MCS certified for heat pumps and Checkatrade members.
What warranty do I get?
The manufacturer provides it, on its own terms. Some terms depend on regular servicing by a qualified engineer so it’s worth keeping the service records.

Circuit boards and sensors
Testing comes before any part is replaced because swapping parts on a guess wastes money. Parts may need ordering and we’ll explain any wait.
Refrigerant leaks
Adding refrigerant without a repair is not a fix, and it releases more refrigerant into the air. We always find and fix the leak first.

Aftercare tips
Every system needs looking after, and most of it is easy. A few tips:
- Send us a photo of any code on the display
- If there’s ice on the pipes, switch off and let it melt
- Book an annual service after the repair
You get a note of the fault and what we did: what was wrong, what was replaced and any refrigerant work. Any refrigerant work is recorded in the F-Gas records, so keep the note with the system’s paperwork.
Book an annual service. The engineer cleans what you cannot reach and picks up problems before they cause a breakdown, which is far simpler than an emergency repair.
