- A home office that warms up with screens and equipment
What happens on the day
Testing is the last part of the visit wherever the system can be switched on. 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. The visit takes a day or more, depending on the number of rooms, the pipe routes and the access. Seeing the property in photos first means the trip to Duddleswell can be planned properly.
- 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.
- The units go up and the pipework, cable and condensate drain are run neatly 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
- Arrange for someone to be there to let us in
- Tell us about parking and loading
- Have the make and model of any existing unit to hand

Advice
Air conditioning for homes and businesses in Duddleswell
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. Most enquiries from Duddleswell start with one hot room: a bedroom, a home office or a loft conversion. That’s usually a single wall-mounted split, from £1,200 + VAT.
Around Duddleswell, many people choose a system that heats as well as cools, which suits garden rooms, lofts and extensions that the main heating struggles with.
Warranty periods vary by brand and by product. 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. Whatever the brand, the manufacturer’s terms are explained on your quote.

Do you need air conditioning in Duddleswell?
Not everyone is after cooling. Direct electric heaters convert electricity into heat one for one, while an air-to-air heat pump moves heat from outside, so it gives out more heat than the electricity it uses. That is how most modern split systems work.
Reasons to give us a call include:
- A room that is unbearable on warm days
- Rooms heated by plug-in heaters
- A study or office that overheats during the day
Modern air conditioning can heat as well as cool, which suits rooms the main heating does not reach.
What your quote should include

Air conditioning in Duddleswell: local notes
At about 33 miles from central London, Duddleswell sits inside the area we cover across London and the South East. The Valuation Office Agency’s council tax figures put about 43% of homes in the Duddleswell area before 1919, and Census 2021 figures found about 87% 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. With homes like that, finding a sensible outdoor unit position is rarely hard, and a multi-split lets two or more rooms run off it.
A loft bedroom or a glazed extension is often the room that prompts the first call.

Your questions about air conditioning in Duddleswell
Can I get a fixed-price quote for air conditioning in Duddleswell?
Send us photos of the room or the system and a few details about the property. Where photos are not enough, a survey comes first and the fixed-price quote follows.
Is Duddleswell within the area you cover?
Yes. Duddleswell is within the area we cover across London and the South East. We are based in East Grinstead and plan each visit so the job can be finished in one trip where possible.
Do you work on commercial properties?
Yes. From one rented home to commercial buildings, the approach is the same: survey or diagnosis, a fixed price and proper paperwork.
Will you work on another installer’s system?
Yes. We look at it first and tell you what we find, including anything about the original installation that needs putting right. Any work is priced before it goes ahead.
Are you F-Gas certified?
As the law requires for refrigerant work, we are an F-Gas certified company. NICEIC approval, MCS certification for heat pumps and Checkatrade membership sit alongside it.
What size air conditioning unit do I need?
It depends on the room, not only its floor area. Windows, the direction the room faces, the roof above and the people and equipment in it all count and the survey covers each of them.
Whose job is it to check the system for leaks?
The F-gas rules share it between the equipment’s operator and the engineers who work on it. The interval depends on the refrigerant charge, measured in tonnes of CO2 equivalent: at least every 12 months from 5 tCO2e, and every 6 months from 50 tCO2e.
What owners can safely do
Keep a note of anything odd: an error code, a new noise, a drip, a smell or a change in how well the system heats or cools. It helps us diagnose quickly, and a photo or a short video of the display is even better.
Never try to top up, release or handle refrigerant yourself. The law requires anyone working on equipment containing F gas to hold the right qualifications, and the company to be certified, and refrigerant lines can cause cold burns. A suspected leak is our job, not yours.
