Air conditioning installation in Dunton Green

Air conditioning in Dunton Green, done properly
We approach an installation much as a doctor approaches a patient: the survey diagnoses what the rooms need, the installation is the treatment and commissioning is the sign-off. At sign-off, the system is tested in each mode, the controls are explained and the F-Gas records are left with you. Air con, air conditioning, a split system: whatever you call it, in Dunton Green it means the same thing to us: the right unit in the right place, fitted and commissioned properly.
A single room takes a day in most homes, while multi-split systems for several rooms can take longer.
Around Dunton Green, many people choose a system that heats as well as cools, which suits rooms the main heating does not reach well, such as a garden room or loft.
Warranty on the equipment is the manufacturer’s own, on the manufacturer’s terms, and we explain those terms on your quote. Each brand sets its own conditions, so we go through them with you rather than leave you to find the small print.

FAQs for Dunton Green
Will air conditioning in Dunton Green need planning permission?
It comes down to the building and the spot chosen for the outdoor unit. The centre of Dunton Green is in a conservation area. A system that heats as well as cools may not need an application on a house, provided it stays within the permitted development limits. Cooling-only units get no such allowance, and listed buildings and road-facing positions in conservation areas need more care. We speak to the planning department at Sevenoaks council, usually the authority for Dunton Green when it matters.
Is Dunton Green within the area you cover?
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.
How do you size the system?
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, so we explain why we’ve chosen a particular output.
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 a position facing a road can bring extra planning considerations. We will tell you what to check before we fit it.
How does the warranty work?
It’s the manufacturer’s warranty, which varies by brand. For example, Daikin’s standard warranty on split air conditioning is 2 years and we explain the terms for your brand on the quote.
How much does air conditioning installation cost?
Typically £1,200–£2,200 + VAT for a single-room split, depending on the room, the access and the pipe route. Where you sit in the range depends on pipe length, access, electrics and the model, and commercial systems are priced after a survey.
Do you look at the job first?
Yes, every time. Diagnosis comes before treatment: the survey tells us what the job needs and how to do it, and the quote is based on that.
The process
Testing is the last part of the visit wherever the system can be switched on. Then we explain what was done and answer your 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. A few photos help us make the most of a visit to Dunton Green.
- We survey the property, or work from your pictures for a simple job.
- The system is sized, positions are agreed and the price is fixed.
- We protect the area, then fit both halves of the system.
- Connections are made, checked for leaks and pulled down to a vacuum.
- It’s switched on, checked and handed over with its records.
How to prepare
- Clear the space around the indoor unit, or where it will go
- Have the make and model of any existing unit to hand
- Let us know where we can park and unload
How to get a quote
Some jobs can be priced from photos, while others need a survey. Multi-room systems, commercial buildings and anything with a long or hidden pipe route are normally surveyed first. Either way, you get a fixed price before any work is booked.

Why act early in Dunton Green
Putting up with another summer of portable units and fans rarely makes sense. A fixed system removes the heat to the outside, runs more quietly in the room and can usually heat as well, so it works for you in winter as well. Small faults tend to grow, so it’s worth dealing with them early.
The cost depends on the system and the number of rooms or units, the access and what the work involves. We give you a fixed price before work begins, so you know where you stand.

What we are called out for in Dunton Green
Most overheating comes from heat gained through the day. Sunshine through glazing, especially on south and west-facing rooms, adds a lot of heat, and once the room has warmed up, it holds on to it into the evening.
Any of these is worth a proper look:
- Bedrooms and offices that overheat in summer
- An old system that needs replacing
- Commercial rooms that are too warm for staff
Knole House, about 2.5 miles south-east, is one of the historic houses nearby, and if your own home is listed, consent comes before any air conditioning is fixed to it.
