Air conditioning installation in Coldharbour
Air conditioning isn’t only for summer: most modern splits heat too. The Energy Saving Trust makes the same point: an air-to-air heat pump is what many people simply call air conditioning, so a well-chosen unit can be useful in winter as well as summer. If you want air conditioning in Coldharbour, you get one team and one number from survey to sign-off.
Many installs in Coldharbour can go ahead as permitted development, but listed buildings, conservation areas and flats need more care: we flag that at the survey.
Homes around Coldharbour typically have room outside for an outdoor unit. More often it’s the walls, the electrics and the length of the pipe run that need thinking about.
Each manufacturer sets its own warranty period. For example, Daikin’s standard warranty on split air conditioning is 2 years, and its longer extensions apply to its air-to-water units only. For any other brand, we explain the manufacturer’s terms on your quote.

What the work involves, system by system
Ducted systems
Ducted units can feed several rooms through a network of ducts, and they’re easiest to fit while ceilings are open, such as during a refurbishment.
Wall-mounted split systems
For one room, a wall-mounted split is often the simplest answer. One unit inside, one outside, connected by pipework, a cable and a drain, with the route agreed on the survey.
Your questions about air conditioning in Coldharbour
Do you cover smaller places like Coldharbour?
Yes. Coldharbour is within the area we cover across London and the South East. A few photos and the postcode are enough to get things started.

Yes. Coldharbour is one of the places we cover. To start, call us on 07833 053749 or send an email with a few pictures.
How do you keep the place clean during the work?

How does the warranty work?
The manufacturer provides it, on its own terms. Some brands make regular servicing a condition so it’s worth keeping the service records.
What does it cost to install air conditioning?
It depends on the rooms, the system and the pipe route, but a single-room split is typically £1,200–£2,200 + VAT. Where you sit in the range depends on pipe length, access, electrics and the model, while commercial systems are priced after a survey.
How long does air conditioning installation take?
Allow a day for most single-room installations, with multi-split, ducted and cassette systems taking longer. We confirm the time when we quote, so you can plan around it.

What an install looks like in Coldharbour
Central Coldharbour is inside the Coldharbour Conservation Area. Listed buildings are part of the picture here: about 5 within half a mile of the centre, such as Christ Church (grade II). That matters for air conditioning: permitted development does not apply within the grounds of a listed building, in a conservation area the outdoor unit can’t go on a wall or roof facing a road, and a unit used only for cooling isn’t covered at all, so we check with Mole Valley council, normally the planning authority here where needed. Valuation Office Agency council tax records put about 40% of homes in the Coldharbour area before 1919, and the last census (2021) found about 76% of households in detached or semi-detached houses. Older homes often have solid walls, which take longer to core drill, so we plan pipe routes carefully and keep them as discreet as we can. 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 Christ Church, a quick check of the listing and conservation maps is part of planning any install. Starting with one room is common, and the outdoor unit can be chosen with more rooms in mind.

After we have gone
After the visit, a few habits help:
- Keep the room closed while it runs
- Never run the system with the filters out
- File the paperwork with the manual
The filters are the one part you will look after yourself, so we show you how. Clean them every few weeks when the system is in heavy use, following the manual, and keep the outdoor unit clear of leaves and clutter.
Have the system serviced once a year. A service cleans what you cannot reach and picks up faults before they stop the system, and it keeps any warranty servicing conditions in order.
How the visit works
You don’t need to do much on the day. Just let us in and point us to the units, or to where they’ll be fitted, and we take it from there. Before we leave, the area is tidied and we explain what we’ve done. We plan the trip to Coldharbour around you.
- First comes a site survey, or photos and measurements for a straightforward job.
- The quote is fixed and shows the equipment, where each unit goes and what’s included.
- The units go up and the pipework, cable and condensate drain are run neatly between them.
- Once the electrics are connected, the pipework is tested for leaks and put under vacuum before any refrigerant flows.
- The system is commissioned and checked in every mode, and we hand over the controls, F-Gas records and warranty information.
Preparing for the visit
- Make sure we can reach the consumer unit or fuse board
- Keep pets out of the rooms we are working in
- Mention any parking restrictions near the property
