Air conditioning for homes and businesses in Charlton
Across Charlton, every installation follows the same steps: a site survey, or photos for simple jobs, then a fixed-price quote, the installation, commissioning and F-Gas records. The price is fixed up front and the records are handed over at the end. Air conditioning installation in Charlton starts with a site survey, then a fixed-price quote that names the make and model.
Outdoor units around Charlton often sit on the ground or a low wall bracket at the back of the house, where it’s tucked away but still easy to reach for servicing.
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, so keep it safe.

Aftercare tips
After the visit, a few habits help:
- Avoid setting it far colder than you need
- Never run the system with the filters out
- Close windows and doors while the system is cooling
You get the paperwork that matters: F-Gas records, commissioning details and the manufacturer’s warranty terms. Keep them with the manual, because the manufacturer or a future engineer may ask to see them.
Report drips, noises or error codes early. A drip, a noise or a flashing light is often an early sign of a fault, and early repairs are typically simpler.
What we are called out for in Charlton
Rooms in the roof are often the hardest to keep cool. The roof takes the full force of the sun, and warm air rises from the floors below, so a bedroom or office under the roof can stay warm well into the night.
It’s time to call us if you’re dealing with:
- An old system that needs replacing
- Commercial rooms that are too warm for staff
- Rooms heated by plug-in heaters
Older streets near Holy Trinity Church may fall within a conservation area, so we check the planning position before choosing where the outdoor unit goes.
Before booking anyone
- Whether extra work needs your approval first
- Proof of F-Gas company certification
- Whether they looked at the job before pricing it
Leave it or put it right?
A system that is the wrong size never works well. An undersized unit runs hard and still can’t keep the room cool; too big, and it switches on and off and wastes energy. Sizing each room properly on the survey avoids both. Getting the date in early helps for a job in a place like Charlton.
The price reflects the work, not guesswork. That’s why we look at the job first, from photos or on a survey, and why the quote is fixed before work begins.
Why book with us
- A reply the same working day
- Manufacturer’s warranty terms explained on your quote
- One number for homes and businesses across London and the South East
- MCS certification for heat pump work

What an install looks like in Charlton
There are 2 conservation areas within a mile of the centre of Charlton. Historic England lists about 34 buildings and structures within half a mile of the centre of Charlton, including Yew Tree Cottage (grade II). Before any outdoor unit is fixed here, we find out whether the building is protected. Where it is, Vale of White Horse council, usually the planning authority here has the final say on what’s allowed. About 31% of homes across Charlton and its surrounding area have been built since 2000, according to the Valuation Office Agency’s council tax figures. Newer homes usually have cavity walls and loft space that make pipe runs easier, though some estates have planning conditions or covenants worth checking.
A loft bedroom or a glazed extension is often the room that prompts the first call.

How the visit works
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. All told, the work takes a day for most single-room installations, with multi-split, ducted and cassette systems taking longer. We load the van from the survey notes so the work in Charlton can be done in one go where possible.
- We start by looking at the rooms, the walls and where the outdoor unit can go.
- Cooling loads are worked out room by room, and the written price names the make, the model and every position.
- Brackets go on, the units are hung and the refrigerant lines, cable and drain are routed between them.
- Power is wired in, the joints are proved leak-tight under pressure and a vacuum pump draws out air and moisture.
- The system is commissioned and checked in every mode, and we hand over the controls, F-Gas records and warranty information.
How to prepare
- Give us access to the outside wall, roof or yard where the outdoor unit sits
- Clear access to the fuse board
- Move furniture away from the wall where we will be working
How to get a quote
Every quote starts with a look at the job, either on a site survey or, for simple jobs, from your photos and details. After that, we send a fixed price so you know the cost before we begin.

Questions from Charlton
Do you cover smaller places like Charlton?
We do. Villages and hamlets get the same service as the bigger towns. Visits to smaller places are planned so the engineer arrives with what the job needs.
Do you cover Charlton for air conditioning?
Yes, Charlton is within the area we cover. To start, call 07833 053749 or use the quote form with a few photos.
Do you work on commercial properties?
Yes. We work for homeowners, landlords, letting and managing agents, and businesses of every size across London and the South East. Let us know who the records should go to.
Will you need to do electrical work?
Usually, yes. The fuse board is checked on the survey, and any electrical work goes on the quote, and our NICEIC approval covers the installation and certificate.
Do you offer maintenance contracts?
Yes. Maintenance contracts are part of what we do, with visits at the interval your system and the manufacturer need. Each visit is recorded, with F-Gas records where refrigerant work is involved.
Do I need to service the system to keep the warranty?
That depends on the brand. Where servicing is a condition, a missed service could give the manufacturer grounds to refuse a claim, so we explain the terms on your quote.
Will you work on another installer’s system?
Yes. We work on systems fitted by other installers as well as our own from all the leading brands. Send us the make and model, and any records you have.
