Keeping the system healthy
Simple habits make a real difference. We recommend:
- Keep the outdoor unit clear of leaves, plants and clutter
- Close windows and doors while the system is cooling
- Tell us if the unit starts to leak, rattle or show a code
The handover includes the records you need: F-Gas records, commissioning details and the manufacturer’s warranty terms. File them together, because the manufacturer or a future engineer may ask to see them.
Keep the outdoor unit clear. Leaves, plants, bins and stored items around it restrict the airflow, and the system has to work harder as a result.

Single-room systems are typically £1,200–£2,200 + VAT, two rooms on a multi-split £2,800–£4,500 + VAT, and three to five rooms £4,500–£8,500 + VAT. Those ranges include supply, installation, commissioning and F-Gas documentation, with commercial and VRF systems priced after a survey. Every installation in Windmill Hill begins with a look at the rooms, the walls and where the outdoor unit can go, followed by a fixed-price quote with the brand, model and every part of the job set out.
A typical install in Windmill Hill is an indoor unit high on an outside wall, a neat pipe run and an outdoor unit on a bracket or ground pad, with the drain run planned so it never drips where it shouldn’t.
Around Windmill Hill, many people choose a system that heats as well as cools, which suits rooms the main heating does not reach well, such as a garden room or loft.
For a fault on a system that may still be under warranty, send us the make, model and installation date. We will explain how the manufacturer’s terms are likely to apply before anything chargeable is done.

When to call us in Windmill Hill
Loft rooms and top floors tend to suffer most. Heat comes in through the roof and rises from the rest of the building, so a bedroom or office under the roof can stay warm well into the night.
It’s time to call us if you are dealing with:
- Bedrooms and offices that overheat in summer
- Uncertainty over the right type and size of system
- A home office that warms up with screens and equipment
With historic houses such as Horselunges Manor about 4 miles west, it’s a reminder that older homes nearby may be listed, which changes the planning rules.
What to look for in a quote
- Whether they hold F-Gas company certification, not just individual qualifications
- Whether the electrical work is done by a registered contractor, such as NICEIC approved
- What’s in the price and what is not
Questions from Windmill Hill
Do I need planning permission for air conditioning in Windmill Hill?
It depends on the property. The half-mile around the middle of Windmill Hill holds about 16 listed buildings and structures. A system that heats as well as cools may not need an application on a house, provided it stays within the permitted development limits. Cooling-only units get no such allowance, and listed buildings and road-facing positions in conservation areas need more care. We speak to the planning department at Wealden council, typically the authority for Windmill Hill when it matters.
Do you cover smaller places like Windmill Hill?
Yes. Windmill Hill is within the area we cover across London and the South East. A few photos and the postcode are enough to get things started.
Are you F-Gas certified?
AirCon Doctor is an F-Gas certified company, with NICEIC approval for electrical work and MCS certification for heat pumps. We are members of Checkatrade too.
How long will the installation take?
It takes a day for most single-room installations, with multi-split, ducted and cassette systems taking longer. The survey tells us how long your installation will need so there are no surprises.
Does air conditioning need its own electrical supply?
Typically, yes. The fuse board is checked on the survey, and any electrical work goes on the quote and we install and certify the circuit as NICEIC approved contractors.
What size air conditioning unit do I need?
We size each room on the survey, from its size, glazing, orientation and use. Too small, and it runs flat out; too big, and it switches on and off and wastes energy, so we explain why we have chosen a particular output.
Do you protect the property while you work?
We start with protection: sheets over the floor and nearby furniture. Holes and fixings are agreed with you, and we clean up afterwards before we leave.
Air conditioning around Windmill Hill
About 85% of households live in detached or semi-detached houses, according to Census 2021 figures. Houses normally have a side or rear wall with room for the outdoor unit, and a multi-split can serve several rooms from one outdoor unit.
Bedrooms under the roof and rooms with big sunny windows are typically the first to overheat, so they’re the usual place to start.
