How we handle air conditioning in Charlton
Most modern split systems run as heat pumps, so they can heat as well as cool. The Energy Saving Trust recognises that air-to-air heat pumps often go by the name air conditioning, and a well-chosen system can earn its keep all year round. Need an air conditioning installer for Charlton? We’re based in East Grinstead and cover London and the South East, as an F-Gas certified company with NICEIC approval.
Sizing is where cheap installs go wrong: we look at the room’s size, windows, insulation and use before choosing a unit.
Homes around Charlton typically have room outside for an outdoor unit. The questions are more often the age of the walls, the electrics and how far the pipes need to run.
Refrigerant work is written up in the F-Gas records: the work carried out, the refrigerant involved and the quantities. File them with the system’s paperwork, as a manufacturer or a future engineer may ask to see them.

Rented and managed buildings
Records are where property maintenance often slips. Each visit produces a dated record, plus the F-Gas records where refrigerant is involved, ready for a tenant, a buyer or an inspection.
We also work for facilities teams in offices, schools and public buildings in Charlton and across West Sussex. Larger buildings can be done in stages around the people who use them.
What an install looks like in Charlton
About 71% of households live in detached or semi-detached houses, according to the last census (2021). With homes like that, finding a sensible outdoor unit position is rarely hard, and a multi-split lets two or more rooms run off it. Charlton’s centre falls inside the Charlton Conservation Area. Draw a one-mile circle round the middle of Charlton and it takes in 2 conservation areas. About 21 listed entries lie within half a mile of central Charlton, Fox Hall (grade II*) among them. Heritage protection changes what an install can involve, so the survey looks at your address first and tells you plainly whether consent is likely.
If your home is in one of the older streets near The Parish Church of the Blessed Virgin Mary, it’s worth checking whether it’s listed or in a conservation area before an install. With historic houses such as West Dean House about 1.7 miles west, it’s a reminder that older homes nearby may be listed, which changes the planning rules.

Your questions about air conditioning in Charlton
Do you cover smaller places like Charlton?
We do. Villages and hamlets get the same service as the bigger towns. We are based in East Grinstead and plan each visit so the job can be finished in one trip where possible.
Do you cover Charlton for air conditioning?
We do: Charlton falls inside our working area. Get in touch with the details and we reply the same working day.
How do you size the system?
It depends on the room, not only its floor area. Glazing, orientation, the roof and what goes on in the room all affect it, and we take them all into account on the survey.
Do you work for landlords and businesses?
Yes. From a single let flat to offices, shops and public buildings, we work the same way: a look first, a fixed-price quote and written records.
When will I hear back?
You will hear from us the same working day. For a breakdown that cannot wait, call our 24/7 emergency line.
Do you offer maintenance contracts?
Yes. Send details of the systems and how they’re used, and we will suggest a schedule with a fixed price. Leak checks required by the F-gas rules can be built in for larger systems.
Can I use air conditioning to heat a room?
Yes, most modern split systems run as heat pumps, so they can heat a room in winter. The Energy Saving Trust points out that an air-to-air heat pump is often just called air conditioning. Some cooling-only models exist, so we confirm it for the model on your quote.
The process
Wherever the system can be run before we leave, we run it and check it in operation. Then we show you what we’ve done and answer any questions, and anything that needs a follow-up is pointed out there and then. The visit takes about a day for a single-room system, longer for multi-room and ducted systems. Rural lanes and tight entrances are worth mentioning before a visit to Charlton.
- Diagnosis comes first, with a survey of the rooms, outside space and fuse board.
- Then the prescription: the right system and size for each room, on a fixed-price quote.
- Then the work: units up, pipes and drain run, and a new circuit where needed.
- Before it runs, the pipework is proved tight and put under vacuum.
- Finally, the clean bill of health: commissioning, the controls explained and your paperwork handed over.
Before we arrive
- Have the make and model of any existing unit to hand
- Plan for pets to be kept clear during the visit
- Name a contact who can meet us at the agreed time

What else we do in Charlton
What you can do yourself, and what needs us
Never try to top up, release or handle refrigerant yourself. The law requires anyone working on equipment containing F gas to hold the right qualifications, and the company to be certified, and escaping refrigerant can cause cold burns. If you suspect a leak, switch the system off and call us.
There are a few things you can safely do yourself: keep the outdoor unit clear of leaves, plants and clutter, check the settings and the remote, and follow the cleaning the manual describes. Anything inside the units, the electrics and the refrigerant is engineer’s work.
What affects the quote in Charlton
We quote each job individually. This is what makes a difference:
- The number of rooms, units or zones
- How far the pipework has to run, and where
- Which make and model is being fitted or worked on
The price reflects the work, not guesswork. That’s why we look at the job first, from pictures or on a survey, and the price is agreed before we start.
What we need to know
You don’t need the technical terms. Just send:
- The paperwork from the last service, if you have it
- Your consumer unit or fuse board
- The postcode and whether it’s a home, flat or business
The quickest way to a quote is to send pictures: the room or the existing unit, the outside wall or roof where the outdoor unit sits or would go, and the label on any existing unit. Add the address and what you’d like done, and simple jobs can often be priced without a visit.
A customer’s words
“Very professional from the initial survey through to installation. The engineer explained everything clearly and the quote was exactly what we paid. Would not hesitate to recommend AirCon Doctor.”
