Common questions in Blenheim
Is Blenheim in your area for air conditioning?
Yes, Blenheim is within the area we cover. Get in touch with the details and we reply the same working day.
Is planning permission needed for air conditioning in Blenheim?
That depends on the building and where the outdoor unit goes. Central Blenheim is a short walk from the Garsington Conservation Area. 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 needed, we check with South Oxfordshire council, which is normally the planning authority for Blenheim.
How do you size the system?
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 we take them all into account on the survey.
Does air conditioning need its own electrical supply?
In most cases, 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 as NICEIC approved contractors we install and certify it as part of the job.
Do I get paperwork after the visit?
Yes, always. A new system comes with commissioning details, F-Gas records and the manufacturer’s warranty information, while repairs and services get a written note of what was found and done.
Do you work on all makes?
We work with the leading brands, from Mitsubishi Electric, Daikin and Fujitsu to Panasonic, Toshiba, LG, Samsung, Mitsubishi Heavy Industries and Hitachi. Send us the make and model if you have it.
How long will the installation take?
A single-room system is usually fitted in a day. Multi-split, ducted and cassette systems take longer and the quote says how long to expect.
How we handle air conditioning in Blenheim
We approach an installation much as a doctor approaches a patient: the survey diagnoses what the rooms need, the installation is the treatment and commissioning is the sign-off. At sign-off, the system is tested in each mode, the controls are explained and the F-Gas records are left with you. Air con, air conditioning, a split system: whatever you call it, in Blenheim it means the same thing to us: the right unit in the right place, fitted and commissioned properly.
Most single-room installs in Blenheim are done in a day, while multi-split systems for several rooms can take longer, and we leave the room clean and the controls explained.
For a home in or near Blenheim, 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.
Think of the paperwork as the system’s health record: what was fitted or found, what was done and when. If anything goes wrong later, it helps the next engineer and the manufacturer, so keep it safe.

Air conditioning around Blenheim
About 77% of households live in detached or semi-detached houses, according to the 2021 Census. 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 Mary may fall within a conservation area, so we check the planning position before choosing where the outdoor unit goes. Garsington Manor, about 0.5 miles south, is one of the historic houses nearby, and if your own home is listed, consent comes before any air conditioning is fixed to it.
Blenheim is about 4 miles south-east of Oxford, in Oxfordshire. Across the OX44 area, we can help with air conditioning. We cover 443 places across Oxfordshire, from busy centres to quieter spots. The nearest of our city pages is Guildford, around 41 miles from Blenheim.
From Wheatley Road and North Manor to the smaller roads in between, nowhere is left out. Work in OX44 follows the same survey, fixed-price quote and written records as everywhere else we cover. We also cover Garsington (1 mile west), Denton (1 mile east), Cuddesdon (1 mile east), Horspath (1 mile north-west) and Littleworth (2 miles north). Further out, we also cover Oxford (4 miles north-west), Didcot (9 miles south-west), Bicester (13 miles north) and Abingdon-on-Thames (6 miles south-west).
What’s near Blenheim
Typical jobs here are in properties near Red Lion pub, Wheatley Park School and Library Farmhouse and the streets around them. The nearest railway station is Radley station, roughly 4.3 miles south-west. Other landmarks nearby include British Tattoo History Museum (3.2 miles north-west) and Oxford Castle (5 miles north-west). Green spaces nearby include Wells Farm and Shotover.
What air conditioning cannot fix
Before booking, it helps to know what’s not included:
- A room that cannot take an outdoor unit or pipe route without the landlord’s, management company’s or council’s consent (that consent comes first)
- Building damp that has a structural cause
- Stuffy rooms that need fresh air rather than cooling
Not sure which it is? You can phone us on 07833 053749 or send an email and we will tell you honestly.

Why act early in Blenheim
New systems now use lower-impact refrigerants. From 2025, single splits under 3 kg cannot use refrigerants with a GWP over 750, which is why R32, with a GWP of 675, is now common. R410A, used in many older systems, has a GWP of 2088. Small faults tend to grow, so it’s worth dealing with them early.
Several rooms, units or sites on one quote often makes better use of the time. Mention every unit or room you need covered and we’ll price it together.
Why us?
- F-Gas company certification
- We work on all the leading brands
- MCS certification for heat pump work
- Warranty terms set out brand by brand
What happens on the day
Each visit follows the same order: agree the plan on site, protect the area, do the work, check the system and explain it all to you. On site, the work takes a day for most single-room installations, with multi-split, ducted and cassette systems taking longer. Rural lanes and tight entrances are worth mentioning before a visit to Blenheim.
- Diagnosis comes first, with a survey of the rooms, outside space and fuse board.
- Next, a recommendation for each room and a fixed price.
- 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.
- The sign-off: commissioning, a walk through the controls, and the F-Gas records and warranty details.
How to prepare
- Let us know if the units are on a roof, a high wall or in a locked area
- Give us access to the outside wall, roof or yard where the outdoor unit sits
- Mention any parking restrictions near the property
Get a fixed-price quote
Photos are the fastest route to a quote: the room or the existing unit, the outside wall or roof where the outdoor unit sits or would go, and the label on any existing unit. Tell us the address and what you need, and simple jobs can often be priced without a visit.

What affects the quote in Blenheim
Our prices page gives typical ranges, but every job is priced on its own. What we look at:
- What electrical work the job needs
- Whether we need access equipment for high-level work
- The condition of any existing system
A single unit or a whole estate, the quote is built the same way: what needs doing, how we get to it and what it needs. You’ll have a fixed price before work begins, and the quote sets out the VAT.
What we need to know
There’s no need for technical detail. It helps if you can send:
- The outside wall, roof or yard where the outdoor unit sits or would go
- The make and model of the system, from the label
- A few photos of the room and the wall the unit is on, or will go on
Quoting starts with a diagnosis, from a site survey or, where the job is straightforward, from photos and measurements. After that, we send a fixed price before any work starts.
What a customer said
“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.”
