Air conditioning servicing in Farnham, done properly
Some systems need F-gas leak checks by law, and some do not. GOV.UK sets the frequency by the system’s tonnes of CO2 equivalent (tCO2e): at least every 12 months from 5 to under 50 tCO2e, and every 6 months from 50 to under 500 tCO2e. We work out where your system sits and check it accordingly. If you are dealing with an unpleasant odour when the system runs and drips or damp patches below an indoor unit, we can help.
For a home in or near Farnham, a service once a year suits most systems, ideally in spring before the warm weather.
Some manufacturers make regular servicing by a qualified engineer a condition of their warranty. Where yours does, a regular service with us keeps that side in order, and every service is written up.

How the visit works
Think of the visit in three stages: diagnose, treat and sign off. First we check the system or the space against the plan, then we do the work, and finally everything is tested, recorded and explained. The middle part takes longest, which takes an hour or so for a single wall-mounted unit, longer for a multi-split system. Photos of the room and the outside of the property help us plan a visit to Farnham.
- A date is fixed and the service price confirmed in advance.
- We switch the system on and check it in operation.
- Then the cleaning: filters, coils, fan and the drain line.
- We check the wiring, controls and refrigerant circuit, and leak check systems that need it.
- A final test run follows, then you get the service record.
How to prepare
- Plan for pets to be kept clear during the visit
- Mention any roof access, ladders or high-level work
- Name a contact who can meet us at the agreed time
Getting a price
Every quote shows the VAT clearly, and the rate that applies to your job is stated. Homes, businesses and different kinds of work can be treated differently for VAT, so we confirm it in writing rather than guess. To get one, give us a ring on 07833 053749 or drop us a line.

System by system
Refrigerant performance and leak checks
F-gas leak checks are required for systems from 5 tCO2e upwards, at least yearly up to 50 tCO2e and every 6 months from 50 to under 500 tCO2e. Hermetically sealed equipment holding less than 10 tCO2e does not need them.
Maintenance contracts
For businesses, a contract keeps servicing and any required leak checks on schedule, with records kept for each visit.

When it’s something else
Air conditioning servicing cannot fix everything, and we will tell you before we start. It won’t put right:
- A unit that was undersized when it was chosen
- Heat from large windows, roof spaces or equipment beyond the system’s capacity
- Parts that have failed and need replacing
Not sure which it is? You can give us a ring on 07833 053749 or write to us at info@aircondoctor.co.uk and we will tell you honestly before booking.

Farnham questions
Will you come out to Farnham?
Yes, and the size of the place makes no difference to how we work. Send a few details and pictures, and we reply the same working day.
Can you do air conditioning servicing in Farnham?
Yes, Farnham is within the area we cover. Tell us a little about the job and we will take it from there.
What’s included in an air conditioning service?
The service covers the indoor units and the outdoor unit: filters, coils, drains and fans, then the electrics, the controls and how the refrigerant circuit is performing. A service record follows.
What’s the price of a yearly air conditioning service?
An annual service is £95–£150 + VAT. We confirm the exact figure before we book the visit and bigger systems are priced once we know what’s installed.
Can I have a maintenance contract for my air conditioning?
We do. A contract sets out how often we visit and what each visit covers, at a fixed price agreed with your quote. It suits anyone who would rather not track service dates.
Do you protect the property while you work?
We put dust sheets over floors and furniture near the work first, and we tidy up as we go. At the end, we clear up and show you what we have done.
When will I hear back?
You will hear from us the same working day. If it’s an emergency, ring the 24/7 line instead.
What affects the quote in Farnham
Before we fix a price, we need to know a few things. We look at:
- Access, including height, roofs and ladders
- The distance and route between the indoor and outdoor units
- How many units are involved
What you pay reflects the actual work. That is why we look at the job first, from pictures or on a survey, and why the quote is fixed before work begins.
What to send for a quote
Photos let us diagnose from a distance. Try to include:
- The rating plate or label on any existing unit
- Where the property is and what kind of building it is
- Your consumer unit or fuse board
Quotes don’t take long. Call or email with a few details and we’ll come back to you the same working day. If we need to see the property first, we book a survey at a time that works for you.
