Air conditioning servicing in Charlton-on-Otmoor, done properly
Servicing does not mean topping up refrigerant. Refrigerant runs in a sealed circuit and shouldn’t need adding to. Where the checks suggest gas has been lost, the right step is to find the leak, and we’ll set out how. If the problem is systems that need a 6 or 12-monthly leak check and ice forming on the pipework or outdoor unit, we can sort it out.
Around Charlton-on-Otmoor, outdoor units sit close to gardens and greenery, so leaves, seeds and cobwebs collect on the coil. A yearly service clears them.
Think of the paperwork as the system’s health record: a dated account of the work and the readings we took. If anything goes wrong later, it helps the next engineer and the manufacturer and it’s worth keeping safe.

What we do, step by step
Where something has to be switched off during the work, we agree it with you first, so you can plan around it. In a business, work can often be done one area at a time. The work takes around an hour for one indoor and one outdoor unit, with extra time for each additional indoor unit. For a village like Charlton-on-Otmoor, tell us about narrow lanes, gates and parking when you book.
- When you book, we ask what make it is, how many rooms it serves and whether anything seems wrong.
- We run the system first and see how it’s performing.
- Filters are cleaned, coils treated and the drain tray and pipe cleared.
- Electrical connections, controls and refrigerant performance are checked, with an F-gas leak check where the system requires one.
- Before leaving, the engineer writes up the visit and talks you through anything worth knowing.
How to prepare
- Move furniture away from the wall where we will be working
- Name a contact who can meet us at the agreed time
- Make sure we can reach the consumer unit or fuse board

Common questions in Charlton-on-Otmoor
How often do you service systems in Charlton-on-Otmoor?
A yearly visit is right for most households. Check your manufacturer’s warranty terms too, as some of them make regular servicing a condition.
Do you cover Charlton-on-Otmoor for air conditioning servicing?
Yes. We work across London and the South East from our base in East Grinstead, and Charlton-on-Otmoor is part of that. Tell us a little about the job and we will take it from there.
Why use an F-Gas certified company?
Anyone installing, repairing or servicing the refrigerant side must be qualified, and their company certified. Ask to see proof before booking anyone, and we are happy to show ours.
Can you look at a system you didn’t fit?
Yes. We start with a proper look and tell you honestly what we find, including any issues with how it was fitted. You get a fixed price before any work goes ahead.
When will I hear back?
On the same working day you contact us. After that, we agree a survey, diagnosis or installation date that suits you, and you get a fixed price before any work goes ahead.
Do you have a 24/7 line?
Yes, 24/7. When you call, tell us the make, what’s happening and any error code, and we will advise on what to do next.
Does my air conditioning need an F-gas leak check?
The requirement starts at 5 tCO2e. Plenty of small splits sit under it, as 3 kg of R32 works out at about 2.0 tCO2e. We read the charge from the label and work it out for you.

Facilities teams in offices, schools and public buildings book us too across Oxfordshire. Work can be phased by floor, zone or building around the people who use them.
Signs you need air conditioning servicing in Charlton-on-Otmoor
Condensate has to drain away from every indoor unit. Debris in the tray or a sticky pump can stop it draining, and the water then has nowhere to go but out of the unit.
Look out for any of the following:
- A musty or damp smell when the unit starts
- Systems that haven’t been serviced for a while
- Warning lights on the indoor unit
Most homes book one service a year; busy offices and shops may want more.
Comparing quotes
- Who does the electrical work, and whether they can certify it

“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.”
