Air conditioning installation in Key's Green, Kent

What owners can safely do
For air conditioning, cleaning the indoor unit’s filters is the main job owners can do where the manufacturer’s manual explains how. They come out, get a gentle clean and go back only when they’re dry. On a heat pump, the equivalent is keeping the outdoor unit clear and checking the controls.
There are a few things you can safely do yourself: keeping the outdoor unit clear, checking the mode and set temperature, and the routine cleaning in the manual. Anything inside the units, the electrics and the refrigerant is engineer’s work.
How we handle air conditioning in Key's Green
Across Key's Green, every installation follows the same steps: survey, fixed-price quote, a neat installation, full commissioning and the F-Gas paperwork. The price is fixed up front and the records are handed over at the end. Modern air conditioning heats as well as cools: in heating mode they work as an air-to-air heat pump, so a system bought for summer earns its keep in winter too.
Where the outdoor unit goes decides how quiet and tidy the job is: airflow, noise towards neighbours, pipe length and access for servicing all count.
In a village like Key's Green, many homes are older, and some are listed. That matters, because a listed home needs consent and permitted development rules do not apply to it, and the outdoor unit position is chosen to suit the building.
Refrigerant work is written up in the F-Gas records: the work carried out, the refrigerant involved and the quantities. Keep the records with the manual and the warranty documents, ready for the next service or a warranty query.

Common questions in Key's Green
Do you cover smaller places like Key's Green?
Yes, smaller places are covered as well as towns. We’re based in East Grinstead and plan each visit so the job can be finished in one trip where possible.
Do you cover Key's Green for air conditioning?
We do: Key's Green falls inside our working area. To start, give us a ring on 07833 053749 or drop us a line with a few photos.
Is air conditioning possible in a flat?
It depends on the building and the lease. Balconies, flat roofs and rear walls can all work, subject to consent and the survey looks at every option. This is general information, not legal advice.
Do I need planning permission?
That depends on what’s being fitted and where. Heat pumps on houses in England can be permitted development when they meet set conditions, including the MCS 020(a) noise check, while a unit that only cools is not covered and needs checking with the council. Listed buildings, conservation areas and flats have extra limits. This is general information, not legal advice.
Where does the outdoor unit go?
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’ll tell you what to check before we fit it.
Can I do the refrigerant work myself?
No, not the refrigerant side. The F-gas rules require certified companies and qualified engineers for it, and a new electrical circuit is notifiable building work unless a registered competent person does it.
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.
What an install looks like in Key's Green
Census 2021 figures found about 74% of households in detached or semi-detached houses. 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. Central Key's Green is inside a conservation area. Listed buildings are part of the picture here: about 9 within half a mile of the centre, such as The Blue Boys Inn (grade II). Heritage protection changes what an install can involve, so the survey looks at your address first and tells you plainly whether consent is likely.
Scotney Castle, about 3.6 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. Around Chapel Of Ease Of St Luke, a quick check of the listing and conservation maps is part of planning any install.

Aftercare tips
Here’s the after-treatment advice, short and simple:
- Keep the room closed while it runs
- Use moderate settings for comfort and economy
- Refit filters properly after cleaning
An annual service keeps the system running efficiently, and some manufacturers make regular servicing a condition of their warranty. We will remind you when it’s due if you’d like.
Keep the outdoor unit clear. Anything piled against it, from leaves to garden furniture, reduces the airflow, which makes the whole system less efficient.
How the visit works
The visit goes in the diary at a time that works for you, and we let you know if plans need to move. When we arrive, we check the job against the survey or the photos you sent. Anything unexpected is raised with you before we go further. After that, it takes a day or more, depending on the number of rooms, the pipe routes and the access. A note on how to find the property and where to park makes a visit to Key's Green easier.
- First the diagnosis: a survey of the rooms, the walls, the outside and the electrics.
- Then the prescription: the right system and size for each room, on a fixed-price quote.
- The treatment: units fitted, pipework and drain routed, and the electrics installed.
- Checks: a pressure test for leaks, then a vacuum to clear moisture.
- The sign-off: commissioning, a walk through the controls, and the F-Gas records and warranty details.
Preparing for the visit
- Name a contact who can meet us at the agreed time
- Have the make and model of any existing unit to hand
- Tell us about access, such as roof hatches, high walls or locked plant areas

Advice
What air conditioning can’t fix
Not every problem is solved by air conditioning, and we will tell you before we start. It doesn’t solve:
- A ventilation problem rather than a temperature problem
- An installation that needs consent nobody has given yet
- Damp or condensation caused by leaks or poor ventilation in the building (that needs the cause fixing)
If in doubt, ring 07833 053749, or email if that’s easier and we’ll say what we think.

A customer’s words
“Office air con broke down in the July heatwave. Called at 8am, engineer was here by noon and fixed within 2 hours. Brilliant emergency response. They now hold the service contract for the whole building.”
