Air conditioning installation in Timsbury
Across Timsbury, 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. A lot of the calls we get from Timsbury are about one room that’s too hot to sleep or work in. A single-room split system is often the answer, from £1,200 + VAT.
Sizing is where cheap installs go wrong: we look at the room’s size, windows, insulation and use before choosing a unit.
Space outside is rarely the problem in a place like Timsbury. More often it’s the walls, the electrics and the length of the pipe run that need thinking about.
Warranty periods vary by brand and by product. For instance, Daikin’s standard warranty on split air conditioning is 2 years, and its longer extensions apply to its air-to-water units only. For any other brand, we explain the manufacturer’s terms on your quote.

The process
The visit has three parts, a bit like a doctor’s appointment: look, put right and sign off. First comes a careful look at the system or the space, then the work itself, and finally everything is tested, recorded and explained. Most of the time goes on the middle part, and that takes a day for most single-room installations, with multi-split, ducted and cassette systems taking longer. Seeing the property in photos first means the trip to Timsbury can be planned properly.
- 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.
- Before it runs, the pipework is proved tight and put under vacuum.
- Finally, the clean bill of health: commissioning, the controls explained and your paperwork handed over.
How to prepare
- Arrange for someone to be there to let us in
- Tell us about access, such as roof hatches, high walls or locked plant areas
- Mention any parking restrictions near the property

What else we do in Timsbury
What happens if it’s left?
The best time to plan air conditioning is before the hot weather, not during it. When people buy in a hurry, the unit is often the wrong size or badly placed, which is costly to undo. Booking the survey early gives you time to weigh up the options. A dirty or faulty system works harder and costs more to run.
The pipe route, the height of the units and how we reach them can all change the price. We take each of them into account, and the price is fixed before work begins.

Timsbury questions
Can I fit air conditioning in Timsbury without planning permission?
It depends on the property. Historic England lists about 11 buildings and structures within half a mile of the centre of Timsbury. 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 isn’t covered, listed buildings need consent and conservation areas restrict outdoor units facing a road. Where necessary, we check with the planning department at Test Valley council, usually the authority for Timsbury.
Do you cover smaller places like Timsbury?
Yes, and the size of the place makes no difference to how we work. We’re based in East Grinstead and plan each visit so the job can be finished in one trip where possible.
Which manufacturers do you install and repair?
We install and work on the leading makes, including Mitsubishi Electric, Daikin, Fujitsu, Panasonic, Toshiba, LG, Samsung, Mitsubishi Heavy Industries and Hitachi. Send us the make and model if you have it.
Which accreditations do you hold?
AirCon Doctor is an F-Gas certified company, NICEIC approved for electrical work and MCS certified for heat pumps. We’re also Checkatrade members.
Can I do any of the installation myself?
Not the refrigerant work. The F-gas rules require certified companies and qualified engineers for it, and a new circuit is notifiable under Part P unless a registered electrician, such as a NICEIC approved contractor, does it.
When will I hear back?
We reply to enquiries the same working day. For a breakdown that can’t wait, call our 24/7 emergency line.
Does servicing affect my warranty?
Check the manufacturer’s terms. Some manufacturers make regular servicing by a qualified engineer a condition of the warranty, so it’s worth checking. Either way, keep a record of every service.
Air conditioning in Timsbury: local notes
VOA council tax data show about 45% of homes in the Timsbury area were built in 2000 or later, and about 73% of households live in detached or semi-detached houses, according to the 2021 Census. Newer homes are often easier to fit, with cavity walls and space in the loft for pipework. Detached and semi-detached houses normally have space for the outdoor unit, and several rooms can share one on a multi-split.
With historic houses such as Mottisfont Abbey about 1.6 miles north-west, it’s a reminder that older homes nearby may be listed, which changes the planning rules. Around Church of St Andrew, a quick check of the listing and conservation maps is part of planning any install.
Timsbury is about 3 miles north-west of Romsey, in Hampshire. Whether you are in the middle of Timsbury or further out, our engineers cover air conditioning, from a single room to a whole building. Timsbury is one of 683 places in Hampshire where we work. There’s also a page for Guildford, about 43 miles away.
You’ll find streets such as Mannyngham Way, The Milburns and New Road, and we cover them all. Our working area takes in SO51. We also cover Michelmersh (1 mile north), Kimbridge (1 mile west), Stonymarsh (1 mile north-west), Mottisfont (2 miles north-west) and Dunbridge (2 miles west). Larger places within reach include Winchester (9 miles east), Eastleigh (8 miles south-east), Andover (13 miles north) and Totton (7 miles south).
What’s near Timsbury
In Timsbury, that means homes and buildings near The Malthouse Inn and The Romsey School. Timsbury’s nearest station is Mottisfont & Dunbridge station, about 1.8 miles west of the centre. Well-known places in the area include Romsey Community Hospital (2.6 miles south-east) and King Johns House (2.5 miles south). The countryside around Timsbury includes Emer Bog and Baddesley Common.
Rented and managed buildings
We also work for facilities teams in offices, schools and public buildings in Timsbury and across Hampshire. Work can be phased by floor, zone or building around the people who use them.
When the building owner and the occupier are different, it’s worth checking the agreement for who looks after the system. We’re happy to deal with either side, and the paperwork can go to both.
What the work involves, system by system
Outdoor unit positions
The outdoor unit can go on a wall bracket, on the ground or on a flat roof, depending on the property and the pipe route. It needs space around it to breathe and for an engineer to work on it.
Pipework and condensate drains
Between the units run the refrigerant pipes, the control cable and the condensate drain. We agree the route with you before we drill and kept as tidy as the building allows.
From one of our customers
“Very professional from the initial survey through to installation. The engineer explained everything clearly and the quote was exactly what we paid. Would not hesitate to recommend AirCon Doctor.”
