Those ranges include supply, installation, commissioning and F-Gas documentation, and commercial VRF systems are priced after a survey.

A typical install in Nashes Green is an indoor unit high on an outside wall, a neat pipe run and an outdoor unit on a bracket or ground pad, with the drain run planned so it never drips where it shouldn’t.
For a home in or near Nashes Green, an air-to-air system can cool in summer and heat in the cooler months, which suits garden rooms, lofts and extensions that the main heating struggles with.
Equipment warranty comes from the manufacturer, on its own terms, and we explain those terms on your quote. Each brand sets its own conditions, and we are happy to talk you through them.

System by system
Outdoor unit positions
Noise is part of the decision: keeping it clear of bedrooms and boundaries where we can, and on anti-vibration mounts. Position can also affect planning.
Ducted systems
A ducted system needs a ceiling void or loft deep enough for the unit and ducts plus an access hatch for maintenance. We check that on the survey before recommending one.
The process
Each visit follows the same order: agree the plan on site, put the dust sheets down, do the work, test what we’ve done and talk you through it. The visit itself takes a day or more, depending on the number of rooms, the pipe routes and the access. Rural lanes and tight entrances are worth mentioning before a visit to Nashes Green.
- 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.
- Then the work: units up, pipes and drain run, and a new circuit where necessary.
- Testing: the circuit is pressure tested and evacuated before the refrigerant is released.
- Finally, the clean bill of health: commissioning, the controls explained and your paperwork handed over.
Preparing for the visit
- Make sure we can reach the consumer unit or fuse board
- Find the manual or the paperwork for the system, if you have it
- Let us know if the units are on a roof, a high wall or in a locked area

Pricing air conditioning in Nashes Green
Before we fix a price, we need to know a few things. We check:
- Whether we need access equipment for high-level work
- Which make and model is being fitted or worked on
- Whether it’s a simple split or a larger system
Height, access and the distance between the indoor and outdoor units all affect the cost. We take each of them into account and give you a fixed price before work begins.
Before you get in touch
There’s no need for technical detail. It helps if you can send:
- The address and the type of property
- A few pictures of the room and the wall the unit is on, or will go on
- A close-up of the unit’s label showing the model number
Every quote shows the VAT clearly, with the rate that applies to your job. Homes, businesses and different kinds of work can be treated differently for VAT, so we confirm it in writing rather than guess. For a fixed-price quote, phone 07833 053749 or write to us at info@aircondoctor.co.uk.
Nashes Green questions
Do I need planning permission for air conditioning in Nashes Green?
There’s no single answer: the building and the outdoor unit position decide it. The half-mile around the middle of Nashes Green holds about 16 listed buildings and structures. Since 2025, an air-to-air heat pump on a house can count as permitted development if it meets the conditions and isn’t used only for cooling. Listed buildings still need consent, and in a conservation area a road-facing wall or roof isn’t allowed under those rules. If there’s any doubt, we ask Basingstoke and Deane council, which is typically the planning authority for Nashes Green.
Do you cover smaller places like Nashes Green?
Yes. Nashes Green is within the area we cover across London and the South East. Send a few details and photos, and we reply the same working day.
Which type of air conditioning is best?
Number of rooms, space outside and how much of the unit you want to see all decide it. Ducted units need a void or loft, and cassettes need a suspended ceiling and the survey confirms what’s possible.
How do I know what size unit to get?
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.
How much is air conditioning for one room?
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, and commercial systems are priced after a survey.
How quickly will you reply?
We reply to enquiries the same working day. For a breakdown that cannot wait, call our 24/7 emergency line.
Do you protect the property while you work?
Floors and furniture near the work are covered with dust sheets before work begins, and we tidy up as we go. Before we leave, we clear up and run through the work with you.
Why it’s worth doing now in Nashes Green
Where the outdoor unit goes matters to you and to the neighbours. A good position keeps noise down and leaves room for servicing, and it can affect whether planning permission is needed. We agree it with you on the survey. Waiting rarely makes an air conditioning problem smaller.
Typical ranges are on our prices page, but your price depends on the job in front of us. Call for a fixed-price quote, and we will explain what it covers.
