About our air conditioning servicing in Charlton
An air conditioning service is a check and clean of the whole system, indoor and outdoor units together. We clean the filters and coils, clear the condensate drain, check the electrics and controls, and look at how the refrigerant circuit is performing. We service systems in Charlton and across Oxfordshire, for most leading brands. The work covers VRF systems, wall-mounted split systems and air-to-air heat pumps, and common reasons people get in touch are water dripping from the indoor unit and humming, rattling or squealing from the system.
For most homes near Charlton, a service once a year keeps the system efficient and the filters clean, and regular servicing can be a condition of some manufacturers’ warranties.
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.

Keeping the system healthy
So the system stays in good health:
- Hold on to every service report
- Do not wait for a small drip to become a leak
- Know your manufacturer’s servicing conditions
Put the next service in the diary right away. Many people book in spring, before the cooling season, or in autumn if they use the system for heating although we service all year round.
Check that the condensate pipe outside can still drain. A pipe that’s been knocked or covered can back up into the indoor unit.
For landlords and property managers
We also work for facilities teams in offices, schools and public buildings across Oxfordshire. Work can be phased by floor, zone or building around the people who use them.
We work for landlords, letting agents and managing agents as well as homeowners and businesses. Let us know who will give us access and who the records should go to, and we’ll keep everyone informed.
FAQs for Charlton
Can you do air conditioning servicing in Charlton?
Yes. We work across London and the South East from our base in East Grinstead, and Charlton is part of that. Get in touch with the details and we reply the same working day.
How often should air conditioning in Charlton be serviced?
Usually once a year for homes, more often for busy business systems. Business systems may also need F-gas leak checks, at least every 12 months from 5 tonnes CO2 equivalent.
Do you offer air conditioning maintenance contracts?
We do, for one unit at home or many across a site. We fix the schedule, the scope and the cost with your quote, so servicing and any required leak checks stay on schedule.
How quickly will you reply?
You’ll hear from us the same working day. If it’s an emergency, ring the 24/7 line instead.
Can you look at a system you didn’t fit?
Yes. We work on systems fitted by other installers as well as our own, on all the main brands. Tell us the make and model and send any paperwork you have.
Whose job is it to check the system for leaks?
The F-gas rules share it between the equipment’s operator and the engineers who work on it. The interval depends on the refrigerant charge, measured in tonnes of CO2 equivalent: at least every 12 months from 5 tCO2e, and every 6 months from 50 tCO2e.
Which accreditations do you hold?
AirCon Doctor is an F-Gas certified company, with NICEIC approval for electrical work and MCS certification for heat pumps. We’re also Checkatrade members.

Keeping systems in Charlton running
Draw a one-mile circle round the middle of Charlton and it takes in 2 conservation areas. About 34 listed entries lie within half a mile of central Charlton, Yew Tree Cottage (grade II) among them. If a repair turns into a replacement on a listed building or in a conservation area, we check the planning position before changing the outdoor unit. About 31% of homes in the Charlton area have been built since 2000, according to the Valuation Office Agency’s council tax figures. Access to the outdoor unit is the one detail that most changes how a visit is planned.
If you look after a school such as Charlton Primary School, servicing is easiest in the holidays. If you can’t remember the last service, it’s probably due.

How the job changes from property to property
Condensate drains and pumps
Slime and debris build up in drain trays over time. A clean tray means fewer drips and fewer smells.
Refrigerant performance and leak checks
The law requires leak checks once a system reaches 5 tCO2e, 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.
How the visit works
Refrigerant work is done by qualified engineers working for an F-Gas certified company, and electrical work is done by us as NICEIC approved contractors. On the day, both are in the same hands. On site, it takes anything from an hour for a simple split system to most of a day for a larger installation. A few photos let us plan a visit to a place like Charlton.
- We start with the basics, such as the brand, the number of indoor units and any symptoms.
- The engineer switches the system on and checks how it behaves before taking anything apart.
- Filters are cleaned, coils treated and the drain tray and pipe cleared.
- Temperatures and pressures tell us how the refrigerant circuit is doing, alongside checks on the wiring and controls.
- We leave you a record of the service and explain anything we found.
How to prepare
- Make sure someone can let us in at the agreed time
- Find the manual or the paperwork for the system, if you have it
- Make sure we can reach the outdoor unit, or where it will go
