Air conditioning installation in Coolham
Not sure what you need, or where it would go? Just ring 07833 053749 or write to us at info@aircondoctor.co.uk with pictures of the rooms and the outside of the property, and we’ll reply the same working day about a survey or a fixed-price quote. Whether you call it air con, air conditioning or an air-to-air heat pump, in Coolham it means the same thing to us: the right unit in the right place, fitted and commissioned properly.
In a village like Coolham, many homes are older, and some are listed. We check that first, because permitted development doesn’t apply within the grounds of a listed building.
If a fault appears while the equipment is under the manufacturer’s warranty, tell us the make, model and installation date. We will explain how the manufacturer’s terms are likely to apply before any chargeable work goes ahead.

Your questions about air conditioning in Coolham
Can you do air conditioning in Coolham?
Yes, Coolham is within the area we cover. Tell us a little about the job and we’ll take it from there.
Can I fit air conditioning in Coolham without planning permission?
It depends on the property. Around 5 listed entries sit within 0.5 miles of central Coolham. Put simply: reversible systems on houses can be permitted development, cooling-only ones cannot, listed buildings need consent, and conservation areas limit outdoor units facing a road. When your property needs a decision, we contact the local planning authority (for Coolham, typically Horsham council).
Will you need to do electrical work?
In most cases. We check your consumer unit on the survey and include any electrical work on the quote and we install and certify the circuit as NICEIC approved contractors.
Does air conditioning work as heating?
In most cases, yes: modern splits are typically heat pumps, so they can heat a room in winter. The Energy Saving Trust points out that an air-to-air heat pump is often just called air conditioning. Some cooling-only models exist, so we confirm it for the model on your quote.
Do you offer emergency call-outs?
Yes, any time. If something urgent happens, like water coming from a unit or a critical room overheating, call our 24/7 line and we will tell you what to do first.
Is the equipment covered by a warranty?
Warranty comes from the manufacturer and depends on the brand and product. Daikin, for instance, gives a standard 2 years on split air conditioning and we explain the terms for your brand on the quote.
How much does air conditioning installation cost?
A single-room split system is typically £1,200–£2,200 + VAT. Two rooms on a multi-split are typically £2,800–£4,500 + VAT, and three to five rooms £4,500–£8,500 + VAT, with supply, fitting, commissioning and F-Gas documentation included. The price is fixed before we start.

What else we do in Coolham
How we price air conditioning
The quote reflects the job in front of us. We consider:
- What electrical work the job needs
- The pipe route between the units
- Whether we need access equipment for high-level work
A single unit or a whole estate, the quote is built the same way: the work involved, the access and the equipment. You’ll have a fixed price before work begins, and the quote sets out the VAT.
Helping us quote
The more you tell us, the more accurate the quote. With your enquiry, please include:
- The address and the type of property
- The outside wall, roof or yard where the outdoor unit sits or would go
- Your consumer unit or fuse board
To help us quote: the address and the type of property, a few photos, the make and model of any existing system and anything you’ve noticed, such as an error code or a noise. Once you have those, ring us on 07833 053749, or email if that’s easier.
Air conditioning in Coolham: the local picture
About 43% of homes in Coolham and the neighbourhoods around it have been built since 2000, according to VOA council tax data, and about 67% of households live in detached or semi-detached houses, according to the 2021 Census. Newer homes usually have cavity walls and loft space that make pipe runs easier, though some estates have planning conditions or covenants worth checking. 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 St Mary's Mission Church may fall within a conservation area, so we check the planning position before choosing where the outdoor unit goes. A loft bedroom or a glazed extension is often the room that prompts the first call.

What we do, step by step
The visit goes in the diary at a time that works for you, and we keep you posted if anything changes. On arrival, the engineer compares the job with the survey, your photos or the details you gave us. 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. A few photos help us make the most of a visit to Coolham.
- We survey the property, or work from your pictures 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.
- 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.
Before we arrive
- Move furniture away from the wall where we will be working
- Find the manual or the paperwork for the system, if you have it
- Mention any parking restrictions near the property

Managing agents and facilities teams in Coolham
Landlords, letting agents and managing agents book us, not only the people who live or work in the property. Let us know who will give us access and who the records should go to, and we will keep everyone informed.
We also work for facilities teams in offices, schools and public buildings in Coolham and across West Sussex. Work can be phased by floor, zone or building to keep disruption down.
Looking after it afterwards
Every system needs looking after, and most of it is easy. Our tips:
- Keep the F-Gas records, commissioning details and warranty information together
- Keep the indoor unit’s filters clean
- Keep to the service interval the manufacturer recommends
The handover includes the records you need: the commissioning details, the F-Gas records and the manufacturer’s warranty information. File them together, because the manufacturer or a future engineer may ask to see them.
Don’t ignore small changes. Water from the indoor unit, a new rattle or a code on the display normally means something needs attention, and early repairs are typically simpler.
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.”
