Air conditioning servicing for homes and businesses in Leatherhead
A service is as much a check-up as a clean. The engineer checks fans, pipe insulation, controls and electrical connections, then explains anything that looks like it could cause a problem later. The work covers VRF systems, multi-split systems and ducted systems, and the jobs we see most are F-gas leak checks falling due and weaker cooling than last year.
If your system in Leatherhead smells musty, drips or has lost some of its cooling, a service is often the first fix, and if it finds a fault, we explain it and price the repair.
Whatever the visit, you get a written record: commissioning details and F-Gas records for a new system, a note of the fault and the fix for a repair, or a service record. File it with the manual, because it helps with any later warranty question.

Leave it or put it right?
A musty smell from the system is rarely something that clears on its own. Cleaning the coil, the fan and the drain tray deals with the cause, rather than masking it. Getting the work done in Leatherhead before summer is the easy option.
Putting the work off seldom saves money. Small problems, from blocked filters to slow leaks, tend to get worse, and a system working harder than it should costs more to run. If you’re not sure what’s needed, give us a ring on 07833 053749 for straight advice and a fixed price.

Questions from Leatherhead
How do I get a quote for air conditioning servicing in Leatherhead?
Use the quote form, or email, with a description of the job. Straightforward work can be priced remotely. Bigger jobs get a survey and a written fixed price.
Is Leatherhead in your area for air conditioning servicing?
Yes. We work across London and the South East from our base in East Grinstead, and Leatherhead is part of that. Get in touch with the details and we reply the same working day.
Do I need a service to keep the manufacturer’s warranty?
The warranty comes from the manufacturer, on its own terms. Check your brand’s conditions, which may mention servicing and file every service record.
How long does the work take?
We’ll confirm the time with your quote. As a guide, the work takes around an hour for one indoor and one outdoor unit, with extra time for each additional indoor unit.
Are you F-Gas certified?
AirCon Doctor is an F-Gas certified company, NICEIC approved for electrical work and MCS certified for heat pumps. We’re also Checkatrade members.
Is an F-gas leak check a legal requirement for my system?
The GOV.UK rules set leak checks at least every 12 months for 5 to under 50 tCO2e and every 6 months for 50 to under 500 tCO2e. With leak detection fitted, the interval can be doubled, and we can tell you where your system sits.
Can we book visits on a schedule?
Yes. We offer maintenance contracts, with visits at the interval your system and the manufacturer need. Each visit is written up, with F-Gas records where refrigerant work is involved.
Keeping systems in Leatherhead running
The Leatherhead Conservation Area lies close to the centre of Leatherhead, within about a third of a mile. The Running Horse Public House, listed at grade II*, is one of roughly 48 protected buildings and structures in the half-mile around Leatherhead’s centre. We keep it in mind in case a new outdoor unit is ever needed, as protected buildings can need consent for that. About 17 miles out from central London, Leatherhead is part of the South East area we work across.
Site managers at schools like Leatherhead Trinity School and Children's Centre can have the site’s units serviced during a holiday. Businesses close to Leatherhead station can book an early or late slot so the service does not get in the way of trade.

Different systems, different jobs
Indoor and outdoor coils
Bent or damaged fins restrict the airflow across a coil. We will point out damaged fins and whether they matter.
Filters
Certain indoor units carry additional filters alongside the main ones. We check these as well and explain what the manufacturer recommends.
What we do, step by step
We book the visit for a day and time that suit you, and we let you know if plans need to move. When we arrive, we check the job against the survey or the photos you sent. If something is different, we talk it through with you before carrying on. From there, the work takes an hour or two for most homes, and longer where there are several indoor units or a ducted system. We book visits in Leatherhead at a time that suits you, and business work around your hours.
- First we take the details: brand, model if you have it, how many indoor units and anything that is been bothering you.
- On arrival, a quick performance check shows how well it’s working before the clean.
- Filters are cleaned, coils treated and the drain tray and pipe cleared.
- The wiring, controls and refrigerant performance are checked, plus a leak check on systems large enough to need one.
- A service record follows, with any faults and the options for fixing them.
Before we arrive
- Let us know if the units are on a roof, a high wall or in a locked area
- Name a contact who can meet us at the agreed time
- Find the manual or the paperwork for the system, if you have it

What owners can safely do
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.
Keep a note of anything odd: an error code, a new noise, a drip, a smell or a change in how well the system heats or cools. It helps us diagnose quickly, and a photo or a short video of the display is even better.

“Office air con broke down in the July heatwave. Called at 8am, engineer was here by noon and fixed within 2 hours. Brilliant emergency response. They now hold the service contract for the whole building.”
