About our air conditioning in New Ash Green
The best installations are planned before a single hole is drilled. We look at each room’s size, glazing, orientation and use, then agree where the indoor and outdoor units go and how the pipework, cable and condensate drain will run before you get a fixed-price quote. Most enquiries from New Ash Green start with one hot room: a bedroom, a home office or a loft conversion. That’s typically a single wall-mounted split, from £1,200 + VAT.
For a home in or near New Ash Green, an air-to-air system can cool in summer and heat in the cooler months, which suits rooms the main heating does not reach well, such as a garden room or loft.
Any work on the refrigerant circuit is recorded: what was done, the refrigerant type and any amount added or recovered. File them with the system’s paperwork, as a manufacturer or a future engineer may ask to see them.

What you can do yourself, and what needs us
Refrigerant is off limits for anyone without the right qualifications. 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.
On air conditioning, the filters in the indoor unit are usually the one part owners can clean where the manufacturer’s manual explains how. With the power off, they lift out, can be vacuumed or rinsed and must be fully dry before they go back. On a heat pump, the equivalent is keeping the outdoor unit clear and checking the controls.
Air conditioning in New Ash Green: local notes
Central New Ash Green is inside a conservation area. Historic England lists about 3 buildings and structures within half a mile of the centre of New Ash Green, including Corner Cottage (grade II). That matters for air conditioning: permitted development doesn’t apply within the grounds of a listed building, in a conservation area the outdoor unit cannot 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 the local planning authority (typically Sevenoaks council) where needed. About 57% of households live in terraced houses, according to the 2021 Census. Terraces have little side access, so the outdoor unit normally goes on the rear wall or a flat roof, with the pipe run kept short.
About 4.3 miles east stands Cobham College. Listed homes in any area need consent first, so tell us if yours is one.

Signs you need air conditioning in New Ash Green
Portable units are often where people start, and why they call us. A portable unit has to vent its warm air through a hose out of a window, which lets some heat back in, and its compressor sits in the room with you. With a split system, the compressor lives outside.
Customers usually contact us when they notice one of these:
- An ageing air conditioning system near the end of its life
- A business premises that overheats in summer
- Expensive direct electric heating
Around Parish Church of Saint Peter and Saint Paul, a quick check of the listing and conservation maps is part of planning any install.

The process
Every visit follows the same order: agree the plan on site, protect the area, carry out the job, test what we’ve done and talk you through it. The visit itself takes a day for most single-room installations, with multi-split, ducted and cassette systems taking longer. We plan the trip to New Ash Green around you.
- 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.
- Brackets go on, the units are hung and the refrigerant lines, cable and drain are routed between them.
- We connect the supply, pressure test the pipework and evacuate it before the refrigerant is released.
- Last comes the run-up: every mode checked, the controls explained and the paperwork left with you.
Preparing for the visit
- Mention any roof access, ladders or high-level work
- Have the make and model of any existing unit to hand
- Let us know where the consumer unit is

FAQs for New Ash Green
Do you cover New Ash Green for air conditioning?
Yes. We work across London and the South East from our base in East Grinstead, and New Ash Green is part of that. To start, call 07833 053749 or use the quote form with a few photos.
Is New Ash Green within the area you cover?
We do. Villages and hamlets get the same service as the bigger towns. Visits to smaller places are planned so the engineer arrives with what the job needs.
Can we book visits on a schedule?
Yes. We offer maintenance contracts, set at the interval the system and the manufacturer’s terms need. Each visit is recorded and F-Gas records kept where they apply.
Do you work on commercial properties?
Yes. Homeowners, landlords, agents and businesses all book us in New Ash Green and across Kent. Let us know who the records should go to.
Do I need a new electrical circuit?
Most of the time, yes: a dedicated circuit is needed. Adding a new circuit is notifiable building work under Part P unless it’s done by a registered competent person, and we are NICEIC approved, so we can install and certify it.
Do I get paperwork after the visit?
Yes. It’s the record a manufacturer or the next engineer will ask to see: the date, the work, and any refrigerant added or recovered.
How much does air conditioning installation cost?
Single-room systems start from £1,200 + VAT and are typically up to £2,200 + VAT. The price includes supply, installation, commissioning and F-Gas documentation and is fixed after a survey or from pictures.
Rented and managed buildings
From a single flat to a whole estate, you get the same standard: diagnosis, a fixed price, access agreed with the people on site and paperwork at the end.
Under the GB F-gas rules, responsibility for leak checks is shared between whoever operates the equipment and the engineers who work on it. In a let or managed building, it’s worth agreeing who that operator is, and we can work for either side.
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.”
