How we handle air conditioning in Thedden
Wall-mounted, multi-split, ducted and cassette systems are all part of what we install, plus VRF systems for bigger commercial buildings. Which one suits you depends on the space, the building and how much of the unit you want to see, and we explain the options on the survey. Most enquiries from Thedden start with one hot room: a bedroom, a home office or a loft conversion. A single-room split system is often the answer, from £1,200 + VAT.
Around Thedden, many people choose a system that heats as well as cools, which suits garden rooms, lofts and extensions that the main heating struggles with.
For a fault on a system that may still be under warranty, send us the make, model and installation date. We’ll tell you how the manufacturer’s warranty is likely to apply before any chargeable work goes ahead.

What affects the cost of air conditioning
Jobs vary more than people expect. The main factors:
- What state the existing equipment is in
- Whether it’s a one-off job or part of a maintenance contract
- The type of system, from a single split to a larger system
What you pay reflects the actual work. That is why we look at the job first, from photos or on a survey, and why the quote is fixed before we start.
Asking for a quote
Good pictures often save a visit. Try to include:
- The paperwork from the last service, if you have it
- Wide photos of the room or the existing unit
- A short video of any fault, such as a noise or a flashing light
For a fixed-price quote, phone us on 07833 053749 or write to us at info@aircondoctor.co.uk and tell us about the property and what you need. Photos help a lot. We reply to enquiries the same working day.
What happens on the day
You don’t need to do much on the day. Someone needs to let us in and show us the units, or where they’re going, and we take it from there. At the end, we tidy up and run through the work with you. A few photos help us make the most of a visit to Thedden.
- We survey the property, or work from your photos for a simple job.
- Output, positions and price are settled before anything is booked.
- Sheets go down first, then the indoor unit and the condenser are mounted.
- We run and connect the pipes, cable and drain, then pressure test and evacuate the circuit.
- The system is commissioned, the controls explained and the F-Gas records handed over.
Before we arrive
- Tell us about parking and loading
- Let us know where the consumer unit is
- Name a contact who can meet us at the agreed time

Thedden: your questions answered
Do you cover smaller places like Thedden?
Yes. Thedden is within the area we cover across London and the South East. A few photos and the postcode are enough to get things started.
Can you do air conditioning in Thedden?
Yes. We work across London and the South East from our base in East Grinstead, and Thedden is part of that. To start, give us a ring on 07833 053749 with a few photos.
How long does air conditioning installation take?
A single-room system is typically fitted in a day. Multi-room and ducted systems take longer, depending on the pipe routes and access and the quote says how long to expect.
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 I need planning permission?
It depends on the system and the property. In England, an air source heat pump on a house can be permitted development if it meets set conditions, including the MCS 020(a) noise check, but a cooling-only unit isn’t covered, so check with the council. Listed buildings, conservation areas and flats have extra limits. This is general information, not legal advice.
Can landlords and managing agents book you?
Yes. From one rented home to commercial buildings, the approach is the same: a look first, a fixed-price quote and written records.
Where will you put the outdoor unit?
Wall brackets, ground level and flat roofs are all options, wherever the pipe route, airflow and servicing access work best. Noise near bedrooms and boundaries is part of the decision and position can affect planning.
Homes in Thedden and air conditioning
Thedden is about 47 miles from central London, well within the area we cover from our base in East Grinstead. About 61% of households live in detached or semi-detached houses, according to Census 2021 figures. 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.
Around St Peter's, a quick check of the listing and conservation maps is part of planning any install. Bentworth Hall (roughly 1 mile west) shows the area has its share of heritage. A listed home needs consent before an outdoor unit or pipework goes on.
Thedden is about 2 miles west of Alton, in Hampshire. From the centre of Thedden to the outskirts, we cover air conditioning, from small jobs to large ones. Our list for Hampshire has 683 entries, and Thedden is one. There’s also a page for Guildford, roughly 21 miles from Thedden.
Our nearest recent job to Thedden was on Castle Street, Farnham (GU9), about 11 miles north-east: installing a Fujitsu multi-split system serving three offices and a client meeting room. More about it
All of GU34 is within our area. Nearby, we also cover air conditioning in Beech (1 mile south-east), Wivelrod (1 mile south-west), Bentworth (1 mile north-west), Holt End (1 mile west) and New Copse (2 miles west). We also work in nearby towns such as Basingstoke (9 miles north), Winchester (14 miles south-west), Farnborough (15 miles north-east) and Fleet (12 miles north-east).
Landmarks near Thedden
The nearest railway station is Alton station, roughly 2.6 miles east of the centre. Other landmarks nearby include Alton Community Hospital (1.6 miles east) and Barton Castle (3.9 miles west). The countryside around Thedden includes King's Hill.
Rented and managed buildings
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 are happy to deal with whoever it is.
When the building owner and the occupier are different, it’s worth checking the agreement for who looks after the system. We can quote either party, and the paperwork can go to both.
What else we do in Thedden
Leave it or put it right?
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, and that’s hard to put right later. A survey now gives time to choose properly. For a village like Thedden, booking ahead lets us plan the trip properly.
One room or a whole building, the quote is built the same way: the work involved, the access and the equipment. You’ll have a fixed price before we start, and the quote sets out the VAT.
