Air conditioning in Merton
A single-room split system is typically £1,200–£2,200 + VAT, two rooms on a multi-split £2,800–£4,500 + VAT, and three to five rooms £4,500–£8,500 + VAT. Supply, installation, commissioning and F-Gas documentation are all included, with commercial and VRF systems priced after a survey. Air con, air conditioning, a split system: whatever you call it, it’s the job we do every week across Oxfordshire.
Getting the size right matters more than the brand: the survey covers room size, glazing, insulation and how the room is used, so the unit isn’t too big or too small.
Villages like Merton often have older houses and cottages, some of them 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.
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.

Rented and managed buildings
Managing agents often deal with us directly. Tell us the property, the work and the access arrangements, and we will send a fixed-price quote.
For anyone managing more than one building, we can plan visits across the portfolio and price them together. Every address has its own paperwork, so the files stay tidy.
Air conditioning in Merton: the local picture
About 44% of homes in and around Merton have been built since 2000, according to VOA council tax data, and about 76% of households live in detached or semi-detached houses, according to Census 2021 figures. Newer homes are often easier to fit, with cavity walls and space in the loft for pipework. A side passage or back wall normally gives the outdoor unit a home, and more than one bedroom can be cooled through a multi-split.
Older streets near Church of St Swithin may fall within a conservation area, so we check the planning position before choosing where the outdoor unit goes.
Merton is about 3 miles south of Bicester, in Oxfordshire. We cover Merton for air conditioning, along with the rest of Oxfordshire. In Oxfordshire alone we list 443 places, and Merton is one. You can also see our page for Guildford, about 49 miles away.
All of OX25 is within our area. If you’re just outside Merton, we cover Fencott (1 mile south), Murcott (1 mile south-east), Charlton-on-Otmoor (1 mile south-west), Wendlebury (2 miles north-west) and Lower Arncott (2 miles east). We also work in nearby towns such as Oxford (8 miles south), Bicester (3 miles north), Abingdon-on-Thames (13 miles south) and Witney (15 miles west).
Local landmarks in Merton
We fit and service air conditioning in homes and premises around The Old Plough pub. For rail, the closest station is Bicester Village station, about 2.7 miles north of the centre. A little further out are Bicester Community Hospital (2.9 miles north) and Bicester Avenue (2.3 miles north). For a walk, there’s Graven Hill and Woodsides Meadow.
Signs you need air conditioning in Merton
In shops, offices and restaurants, the heat comes from customers, staff, equipment and lighting as well as the sun. Keeping staff and customers comfortable is usually what prompts the call, along with keeping equipment rooms at a steady temperature.
Look out for any of the following:
- Working from home in a room that gets too warm
- Rooms under the roof that stay hot into the night
- A portable unit with a hose out of the window
Boarstall Tower (roughly 3.7 miles south-east) shows the area has its share of heritage. A listed home needs consent before an outdoor unit or pipework goes on.

Questions from Merton
Will air conditioning in Merton need planning permission?
It depends on the property. Historic England lists about 8 buildings and structures within half a mile of the centre of Merton. An air-to-air system used for heating as well as cooling can be permitted development on a house if it meets the conditions, but a cooling-only unit is not covered, listed buildings need consent and conservation areas restrict outdoor units facing a road. Where necessary, we check with the local planning authority (for Merton, normally Cherwell council).
Is Merton within the area you cover?
We do. Villages and hamlets get the same service as the bigger towns. Send a few details and pictures, and we reply the same working day.
How long does air conditioning installation take?
Most single-room systems take a day. Multi-room and ducted systems take longer, depending on the pipe routes and access, and we tell you how long on the quote.
Will you make a mess?
We put dust sheets over floors and furniture near the work first, and we tidy up as we go. Before we leave, we clear up and run through the work with you.
Do you offer maintenance contracts?
Yes. We offer maintenance contracts, set at the interval the system and the manufacturer’s terms need. Each visit is written up, with F-Gas records where refrigerant work is involved.
What size air conditioning unit do I need?
Floor area is only part of it. Glazing, orientation, the roof and what goes on in the room all affect it, and we take them all into account on the survey.
What does F-Gas certified mean?
F-Gas certification shows a company is approved to work on equipment containing fluorinated gases, such as the refrigerant in air conditioning and heat pumps. In Great Britain, that certification is a legal requirement, not an optional extra, and AirCon Doctor is certified.
What we do, step by step
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 attention later is pointed out. The visit takes a day or more, depending on the number of rooms, the pipe routes and the access. For a place like Merton, the timing is set with you and the travel is our side of the planning.
- First comes a site survey, or photos and measurements for a straightforward job.
- Each room is sized and you get a fixed-price quote setting out the equipment and the unit positions.
- On the day, we fit the indoor and outdoor units and run the pipework, cable and condensate drain.
- Power is wired in, the joints are proved leak-tight under pressure and a vacuum pump draws out air and moisture.
- Last comes the run-up: every mode checked, the controls explained and the paperwork left with you.
How to prepare
- Mention any roof access, ladders or high-level work
- Name a contact who can meet us at the agreed time
- Tell us about any building rules, permits or sign-in
