Homes in Cold Harbour and air conditioning
About 47% of homes in the Cold Harbour area date from 1945 to 1972, according to Valuation Office Agency council tax records, and about 70% of households live in detached or semi-detached houses, according to Census 2021 figures. Homes of that age typically have cavity or solid brick walls, and we check which before planning the pipe route. Houses typically have a side or rear wall with room for the outdoor unit, and a multi-split can serve several rooms from one outdoor unit.
Harleyford Manor (roughly 3.3 miles north) shows the area has its share of heritage. A listed home needs consent before an outdoor unit or pipework goes on. Living close to Saint Peter? Some older properties in parts like that are protected, and the survey finds out whether yours is.

Air conditioning in Cold Harbour
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. The sign-off includes testing every mode, showing you the controls and handing over the F-Gas records. Most split systems we fit in Cold Harbour are reversible: the Energy Saving Trust notes that air-to-air heat pumps are sometimes called air conditioning, which is why many owners use theirs all year.
In a village like Cold Harbour, many homes are older, and some are listed. That matters, because a listed home needs consent and permitted development rules do not apply to it, and the outdoor unit position is chosen to suit the building.
Warranty periods vary by brand and by product. For example, Daikin’s standard warranty on split air conditioning is 2 years, and its longer extensions apply to its air-to-water units only. Whatever the brand, the manufacturer’s terms are explained on your quote.

What we do, step by step
There’s very little for you to do on the day. Just let us in and point us to the units, or to where they’ll be fitted, and the rest is down to us. At the end, we tidy up and run through the work with you. For a village like Cold Harbour, tell us about narrow lanes, gates and parking when you book.
- You send photos, or we visit and survey the rooms and outside.
- Output, positions and price are settled before anything is booked.
- On the day, dust sheets go down and the indoor and outdoor units are fitted.
- Pipework, cable and drain are run, the circuit is connected and the pipework is pressure tested and evacuated.
- We commission, show you the controls and leave the F-Gas and warranty paperwork.
Preparing for the visit
- Keep pets out of the rooms we’re working in
- Tell us about access, such as roof hatches, high walls or locked plant areas
- Clear a path to the units and the space around them

Advice
What happens if it’s left?
Planning ahead beats a rushed decision in a heatwave. When people buy in a hurry, the unit is often the wrong size or badly placed, and that is hard to put right later. Booking the survey early gives you time to weigh up the options. Planning ahead for a job in Cold Harbour means we can bring everything needed.
One room or a whole building, we price it on the same basis: what needs doing, how we get to it and what it needs. You will have a fixed price before any work starts, and the quote sets out the VAT.

Common questions in Cold Harbour
Is planning permission needed for air conditioning in Cold Harbour?
There’s no single answer: the building and the outdoor unit position decide it. A conservation area takes in the middle of Cold Harbour. Since 2025, an air-to-air heat pump on a house can count as permitted development if it meets the conditions and is not used only for cooling. Listed buildings still need consent, and in a conservation area a road-facing wall or roof is not allowed under those rules. If there’s any doubt, we ask the local planning authority (for Cold Harbour, typically Windsor and Maidenhead council).
Do you cover Cold Harbour for air conditioning?
Yes, Cold Harbour is within the area we cover. Get in touch with the details and we reply the same working day.
Can I have air conditioning in a flat?
In many cases, but permissions come first. Leaseholders normally need consent from the landlord or management company for an outdoor unit and holes through outside walls, so check the lease. Planning rules for flats are tighter too, and we flag anything that may need permission. This is general information, not legal advice.
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. We also think about noise near bedrooms and neighbours, and the position can affect planning.
How do I know what size unit to get?
Floor area is only part of it. Windows, the direction the room faces, the roof above and the people and equipment in it all count and the survey covers each of them.
How long does air conditioning installation take?
It takes anything from a day for one room to several days for a multi-room or ducted system. We confirm the time when we quote so there are no surprises.
Will you work on another installer’s system?
Yes. We start with a proper look and tell you honestly what we find, including anything about the original installation that needs putting right. Any work is priced before it goes ahead.
Keeping the system healthy
After the visit, a few habits help:
- Tell us if the unit starts to leak, rattle or show a code
- Keep the indoor unit’s filters clean
- Never run the system with the filters out
Questions after the installation go to the same number. Tell us what the system is doing, and any code on the display, and we’ll talk it through with you.
Clean the filters regularly, not just at the service. Clean filters keep the air moving and help the system work as designed, which costs you more to run.
When something else is needed
Some problems need a different service or another trade:
- Gas boiler or central heating faults (we don’t work on gas boilers)
- Work that needs permission from a landlord or the council
- Stuffy rooms that need fresh air rather than cooling
If in doubt, give us a ring on 07833 053749 or use the quote form and we will say what we think before you book.

From one of our customers
“Excellent service from start to finish. Two wall-mounted units installed in our home. Clean, tidy work: they protected all the floors and left no mess. The systems work brilliantly. Would highly recommend.”
