Air conditioning in Islip
A single-room split system is typically £1,200–£2,200 + VAT, while a two-room multi-split is typically £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, and commercial VRF systems are priced after a survey. For air conditioning in Islip, one call covers the survey, the fixed-price quote, the installation and the F-Gas paperwork, wherever you are in Oxfordshire.
Most installations here are a wall-mounted indoor unit, a short pipe run through the wall and an outdoor unit on the back or side of the property, with the drain run planned so it never drips where it shouldn’t.
For a home in or near Islip, 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.
Warranty periods vary by brand and by product. Daikin, for example, gives a standard 2 years on split air conditioning, with longer extensions only on its air-to-water heat pumps. For any other brand, we explain the manufacturer’s terms on your quote.

The process
We book the visit for a day and time that suit you, and we keep you posted if anything changes. When we arrive, we check the job against the survey or the photos you sent. Anything unexpected is raised with you before we go further. From there, the work takes about a day for a single-room system, longer for multi-room and ducted systems. Seeing the property in photos first means the trip to Islip can be planned properly.
- You send pictures, or we visit and survey the rooms and outside.
- The system is sized, positions are agreed and the price is fixed.
- We protect the area, then fit both halves of the system.
- Pipework, cable and drain are run, the circuit is connected and the pipework is pressure tested and evacuated.
- The system is commissioned, the controls explained and the F-Gas records handed over.
Getting ready for the visit
- Let us know if the units are on a roof, a high wall or in a locked area
- Keep pets out of the rooms we’re working in
- Move furniture away from the wall where we’ll be working
Getting a quote
To help us quote: the address and the type of property, pictures of the rooms or units, the brand and model of anything already fitted and any symptoms, from error codes to drips. Then phone us on 07833 053749, or email if that’s easier.

After we’ve gone
Here’s the after-treatment advice, in brief:
- File the paperwork with the manual
- Use moderate settings for comfort and economy
- Keep to the service interval the manufacturer recommends
Commissioning is the last stage: every mode is tested before we go. We check it’s running as the manufacturer intends, then show you the controls and the timer, so you are confident using it.
Give the outdoor unit room to breathe. Anything piled against it, from leaves to garden furniture, reduces the airflow, which makes the whole system less efficient.
How we price air conditioning
Our prices page gives typical ranges, and your quote is built on your job. The quote depends on:
- Whether it’s a simple split or a larger system
- What electrical work the job needs
- Whether it’s a one-off job or part of a maintenance contract
The pipe route, the height of the units and how we reach them all affect the cost. We take each of them into account and give you a fixed price before work begins.
What we need to know
Before you ask for a quote, gather:
- Your installation or service records
- Where the property is and what kind of building it is
- The make and model of the system, from the label
VAT is set out clearly on every quote, with the rate that applies to your job. VAT can differ between homes and businesses and between kinds of work, so we confirm it on the quote. To get one, give us a ring on 07833 053749, or email if that’s easier.
Why deal with it now?
Planning ahead beats a rushed decision in a heatwave. A rushed choice is often the wrong size or in the wrong place, which is costly to undo. A survey now gives time to choose properly. Dealing with it now is usually simpler than a breakdown later.
The cost depends on the system and the number of rooms or units, the access and what the work involves. We give you a fixed price before any work starts, so you know where you stand.

Islip: your questions answered
Is Islip within the area you cover?
Yes, and the size of the place makes no difference to how we work. Visits to smaller places are planned so the engineer arrives with what the job needs.
Can you do air conditioning in Islip?
Yes, Islip is within the area we cover. Just ring 07833 053749 or write to us at info@aircondoctor.co.uk with a few details.
Where will you put the outdoor unit?
The position is agreed on the survey, not on the day. It must have clear airflow and space for servicing, and a position facing a road can bring extra planning considerations. We explain the options and any permissions to check.
Can I fit air conditioning or a heat pump myself?
No, not the refrigerant side. Under the F-gas rules, it must be done by qualified engineers from a certified company, and a new electrical circuit is notifiable building work unless a registered competent person does it.
Do you provide F-Gas records?
Yes. It’s your proof of what was done: a dated note of the work, with refrigerant details where they apply.
Can you look at a system you didn’t fit?
Yes. We look at it first and tell you what we find, including any issues with how it was fitted. You get a fixed price before any work goes ahead.
Does servicing affect my warranty?
For some brands, yes. Read the manufacturer’s terms, or send us the make and model and we will explain them, and book the service at the interval they recommend.
Air conditioning in Islip: the local picture
About 51% of homes across Islip and its surrounding area date from 1945 to 1972, according to VOA council tax data, and about 77% of households live in detached or semi-detached houses, according to the last census (2021). We check the wall construction on homes of that age, as it decides how the pipework goes through. 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. The centre of Islip lies within the Islip Conservation Area. About 26 listed entries lie within half a mile of central Islip, Church of St Nicholas (grade I) among them. Before any outdoor unit is fixed here, we find out whether the building is protected. Where it is, the local planning authority (usually Cherwell council) has the final say on what’s allowed.
If you commute from Islip station and work from home on other days, one wall-mounted unit in the home office is often all that’s needed. Homes near St Nicholas' Church are a good example of where we look up the heritage status of the building before fixing anything to it.
Islip is about 5 miles north of Oxford, in Oxfordshire. Wherever you are in the OX5 postcode area, our engineers can take on air conditioning. In Oxfordshire alone we list 443 places, and Islip is one. Guildford, roughly 49 miles off, has its own page on this site.

If you’re just outside Islip, we cover Gosford (2 miles south-west), Hampton Poyle (2 miles north-west), Kidlington (2 miles west), Bletchingdon (3 miles north-west) and Weston-on-the-Green (3 miles north).

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.”
