Air conditioning around Chaldon
Census 2021 figures found about 68% 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.
A loft bedroom or a glazed extension is often the room that prompts the first call. Homes near Church of St Peter and St Paul are a good example of where we look up the heritage status of the building before fixing anything to it.
Chaldon is about 1 mile south-west of Caterham, in Surrey. We cover Chaldon for air conditioning and across the rest of Surrey. Chaldon is one of 395 towns, villages and districts in Surrey where we work for homes and businesses.
Our nearest recent job to Chaldon was on Godstone Road, Caterham (CR3), about 1 mile north-east: installing a Samsung multi-split system serving three bedrooms and a home office. See the job
Chaldon is on the B2031, which makes it straightforward for our engineers to reach for surveys and visits. Work in CR3 follows the same survey, fixed-price quote and written records as everywhere else we cover. Places around Chaldon that are also on our list: Netherne on-the-Hill (2 miles north-west), Merstham (2 miles west), Brewer Street (2 miles south), South Merstham (2 miles south-west) and Hooley (2 miles west). Within a short drive, we also cover Epsom (8 miles north-west), Horley (7 miles south), Redhill (4 miles south-west) and Ewell (8 miles north-west).
Local landmarks in Chaldon
Locally, jobs take us to houses, flats and workplaces close to de Stafford School, Kitchen Copse and The King And Queen Public House and the streets around them. For rail, the closest station is Caterham station, roughly 1.2 miles east of the centre. Well-known places in the area include Bletchingley Castle (2.8 miles south) and St Lawrence's Hospital (0.5 miles north-east). For a walk, there’s South London Downs National Nature Reserve and Nore Hill.
Air conditioning installation in Chaldon
Wall-mounted, multi-split, ducted and cassette systems are all part of what we install, plus VRF systems for bigger commercial buildings. The right choice depends on the rooms, the building and how visible you want the indoor units to be, and we explain the options on the survey. Modern air conditioning heats as well as cools: in heating mode they work as an air-to-air heat pump, which is why many owners use theirs all year.
The outdoor unit position is the biggest single decision: airflow, noise towards neighbours, pipe length and access for servicing all count.
Villages like Chaldon often have older houses and cottages, some of them listed. We check that first, because permitted development doesn’t apply within the grounds of a listed building, and the outdoor unit position is chosen to suit the building.
Nothing is signed off by word of mouth: commissioning details and F-Gas records for a new system, a note of the fault and the fix for a repair, or a service record. File it with the manual, because it helps with any later warranty question.

Keeping the system healthy
Aftercare is straightforward, and it makes the next visit easier:
- Keep the handover documents somewhere safe
- Report drips, noises or error codes right away
- Choose a comfortable set temperature rather than the lowest
The work area is left tidy: dust sheets lifted, offcuts and packaging cleared, and the holes for the pipework sealed. Outside, the pipework is neatly fixed and protected as agreed on the survey.
Regular filter cleaning is the simplest thing you can do. Blocked filters cut airflow and make the system work harder, which costs you more to run.
Chaldon: your questions answered
Will you come out to Chaldon?
Yes, and the size of the place makes no difference to how we work. We are based in East Grinstead and plan each visit so the job can be finished in one trip where possible.
Is air conditioning in Chaldon permitted development?
It comes down to the building and the spot chosen for the outdoor unit. Historic England lists about 3 buildings and structures within half a mile of the centre of Chaldon. Permitted development only covers heat pumps that aren’t used solely for cooling, and not within the grounds of a listed building. Conservation areas add limits on outdoor units facing a road. Where needed, we check with the local planning authority (for Chaldon, usually Tandridge council).
When will I hear back?
The same working day. After that, we agree a survey, diagnosis or installation date that suits you, with a fixed price before work starts.
How do you keep the place clean during the work?
Floors and furniture near the work are covered with dust sheets before work begins, and the area is kept tidy throughout. At the end, we clear up and show you what we’ve done.
Does air conditioning work as heating?
Yes, most modern split systems run as heat pumps, so they can heat a room in winter. The Energy Saving Trust notes that air-to-air heat pumps are sometimes referred to as air conditioning. We confirm the heating function of the model we quote.
Can you look at a system you didn’t fit?
Yes. Systems fitted by other companies are fine, on all the main brands. Tell us the make and model and send any paperwork you have.
How much does air conditioning installation cost?
A single-room split system is typically £1,200–£2,200 + VAT. A two-room multi-split is typically £2,800–£4,500 + VAT, and three to five rooms £4,500–£8,500 + VAT, including supply, installation, commissioning and F-Gas documentation. You get a fixed price before any work starts.
Before you call an engineer
Owners can handle the everyday basics: keeping the outdoor unit clear, checking the mode and set temperature, and the routine cleaning in the manual. Opening up the units, the electrics and the refrigerant circuit are a job for us.
Before you call us about a fault, a few checks can save a visit: is the system in the right mode, is the set temperature sensible, are the remote’s batteries working and has the breaker tripped. If a breaker trips again after you reset it, leave it off and phone us on 07833 053749 or send an email.
Leave it or put it right?
Where the outdoor unit goes matters to you and to the neighbours. A good position keeps noise down and leaves room for servicing, and it can make a difference to planning. It’s agreed on the survey, not on the day. An early booking makes the visit to Chaldon easier to arrange.
What you pay depends on the system and the number of rooms or units, how easy the units are to reach and what the work involves. We give you a fixed price before we start, so you know where you stand.

What we do, step by step
Anything involving refrigerant is handled by F-Gas qualified engineers, as the law requires, while the electrical side is covered by our NICEIC approval. On the day, both are in the same hands. On site, it takes a day for most single-room installations, with multi-split, ducted and cassette systems taking longer. A note on how to find the property and where to park makes a visit to Chaldon easier.
- We start by looking at the rooms, the walls and where the outdoor unit can go.
- We size the system for each room, then send a fixed-price quote with the units and where they go.
- The units go up and the pipework, cable and condensate drain are run neatly between them.
- The electrical supply is connected, and the refrigerant circuit is pressure tested and evacuated.
- Finally, it’s commissioned, tested in each mode and handed over with the F-Gas records.
Before we arrive
- Make sure we can reach the consumer unit or fuse board
- Make sure someone can let us in at the agreed time
- Have the make and model of any existing unit to hand
How to get a quote
