For a home in or near Charlton, an air-to-air system can cool in summer and heat in the cooler months, which suits rooms the main heating doesn’t reach well, such as a garden room or loft.
Any work on the refrigerant circuit is recorded: what was done, the refrigerant type and any amount added or recovered. File them with the system’s paperwork, as a manufacturer or a future engineer may ask to see them.

Air conditioning around Charlton
The last census (2021) found about 77% of households in detached or semi-detached houses. A side passage or back wall normally gives the outdoor unit a home, and more than one bedroom can be cooled through a multi-split.
Around St Thomas, a quick check of the listing and conservation maps is part of planning any install.

Common problems we fix in Charlton
Everything that uses electricity in a room ends up as heat. A home office with a couple of screens, or a meeting room with a few people in it, warms up quickly, even on a mild day.
If any of these sounds familiar, it’s worth a diagnosis:
- An office, shop or restaurant that’s uncomfortable for staff and customers
- Rooms that get too hot to sleep or work in
- Rooms heated by plug-in heaters
If you work from home near Andover station, a home office that overheats is one of the easiest rooms to cool.

Your questions about air conditioning in Charlton
Do you cover Charlton for air conditioning?
Yes, Charlton is within the area we cover. To start, call us on 07833 053749 or use the quote form with a few photos.
Will air conditioning in Charlton need planning permission?
It depends on the property. Historic England lists about 9 buildings and structures within half a mile of the centre of Charlton. Since 2025, an air-to-air heat pump on a house can count as permitted development if it meets the conditions and isn’t used only for cooling. Listed buildings still need consent, and in a conservation area a road-facing wall or roof is not allowed under those rules. If there’s any doubt, we ask the local planning authority (for Charlton, usually Test Valley council).
Will you work on another installer’s system?
Yes. We work on systems fitted by other installers as well as our own, on all the main brands. Send us the make and model, and any records you have.
Where will you put the outdoor unit?
The position is agreed on the survey, not on the day. It must have clear airflow and space for servicing, and walls or roofs facing a road can raise planning questions. We’ll tell you what to check before we fit it.
Do I need to service the system to keep the warranty?
It depends on the manufacturer’s terms. Some manufacturers make regular servicing by a qualified engineer a condition of the warranty, so it’s worth checking. Either way, keep a record of every service.
What size air conditioning unit do I need?
Sizing is done on the survey, room by room. Too small, and it runs flat out; too big, and it switches on and off and wastes energy and we explain the output we recommend.
Is the equipment covered by a warranty?
The manufacturer’s warranty, on the manufacturer’s terms. Terms differ by brand, and we set them out on your quote.

Rented and managed buildings
The F-gas rules share responsibility for leak checking between the equipment’s operator and the service technicians. In a let or managed building, it’s worth agreeing who that operator is, and we can work for either side.
Running several properties is easier with one contractor. We work across London and the South East, so a run of properties can go into one programme and kept on a regular cycle.
What air conditioning cannot fix
An honest diagnosis matters more to us than a booking, so here’s what air conditioning will not do:
- Problems with a gas boiler or the radiators
- A lack of fresh air (most split systems recirculate room air rather than bringing fresh air in, which is a job for ventilation)
- A room that can’t take an outdoor unit or pipe route without the landlord’s, management company’s or council’s consent (that consent comes first)
If in doubt, phone us on 07833 053749, or email if that’s easier and we will say what we think.

What we do, step by step
The visit goes in the diary at a time that works for you, and we keep you posted if anything changes. On arrival, the engineer compares the job with the survey, your pictures or the details you gave us. If something is different, we talk it through with you before carrying on. From there, the work takes a day for most single-room installations, with multi-split, ducted and cassette systems taking longer. Visits to Charlton are agreed with you in advance and planned so the job can be finished in one trip where possible.
- You send pictures, or we visit and survey the rooms and outside.
- Output, positions and price are settled before anything is booked.
- We protect the area, then fit both halves of the system.
- We run and connect the pipes, cable and drain, then pressure test and evacuate the circuit.
- The system is commissioned, the controls explained and the F-Gas records handed over.
Getting ready for the visit
- Plan for pets to be kept clear during the visit
- Move furniture away from the wall where we’ll be working
- Make sure someone can let us in at the agreed time
How to get a quote
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. Tell us the address and what you need, and many jobs can be priced from that.
