About our air conditioning in Donnington
We fit wall-mounted splits, multi-split systems, ducted systems and ceiling cassettes, with VRF for larger buildings. Which one suits you depends on the space, the building and how much of the unit you want to see and we talk you through it on the survey. Whether you call it air con, air conditioning or an air-to-air heat pump, in Donnington it means the same thing to us: the right unit in the right place, fitted and commissioned properly.
Villages like Donnington often have older houses and cottages, some of them listed. That matters, because a listed home needs consent and permitted development rules don’t apply to it, and the outdoor unit position is chosen to suit the building.
The records are your system’s health record: what was fitted or found, what was done and when. It makes the next visit quicker and any warranty question simpler and it’s worth keeping safe.

Air conditioning in Donnington: local notes
The coast is only about 3 miles from Donnington. That is worth knowing for an install, as salt air speeds up corrosion on outdoor coils and fixings, so we choose the position and fixings with that in mind. About 33% of homes across Donnington and its surrounding area have been built since 2000, according to Valuation Office Agency council tax records, and the last census (2021) found about 70% of households in detached or semi-detached houses. Newer homes usually have cavity walls and loft space that make pipe runs easier, though some estates have planning conditions or covenants worth checking. 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.
Older streets near The Parish Church of St George may fall within a conservation area, so we check the planning position before choosing where the outdoor unit goes. Goodwood House (roughly 4.8 miles north-east) shows the area has its share of heritage. A listed home needs consent before an outdoor unit or pipework goes on.

Common questions in Donnington
Does being near the sea make a difference to air conditioning in Donnington?
It can, as Donnington is within about 3 miles of the sea, where salt in the air is hard on coils and fixings. The outdoor unit position, its fixings and regular servicing all help near the sea.
Will air conditioning in Donnington need planning permission?
There’s no single answer: the building and the outdoor unit position decide it. The Donnington Conservation Area takes in the middle of Donnington. 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 Chichester council, usually the authority for Donnington when it matters.
Why use an F-Gas certified company?
The law says any company working on equipment containing F gas has to be certified, and each engineer needs the right qualifications too. It means the refrigerant in your system is handled legally.
Is the equipment covered by a warranty?
Warranty comes from the manufacturer and depends on the brand and product. Daikin, for example, gives a standard 2 years on split air conditioning, and we explain the terms for whichever brand you choose.
Can I do the refrigerant work myself?
Anything that involves the refrigerant needs an F-Gas qualified engineer from a certified company. That’s a legal requirement, and it also matters for the manufacturer’s warranty. We can quote for the whole job, from supply to commissioning.
How soon will you get back to me?
The same working day. After that, we agree a survey, diagnosis or installation date that suits you, and you get a fixed price before any work goes ahead.
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, including supply, installation, commissioning and F-Gas documentation. The price is fixed before work begins.

Landlords, agents and facilities managers
Facilities teams in offices, schools and public buildings book us too in Donnington and across West Sussex. Larger buildings can be done in stages to keep disruption down.
Running several properties is easier with one contractor. Our area covers Greater London and the South East, so a run of properties can go into one programme and kept on a regular cycle.
Keeping the system healthy
A little care keeps the system in better shape. We recommend:
- Keep the outdoor unit clear of leaves, plants and clutter
- Book an annual service
- Keep the F-Gas records, commissioning details and warranty information together
You get the paperwork that matters: 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.
Have the system serviced once a year. A service cleans what you can’t reach and picks up faults before they stop the system and keeps the warranty paperwork right where servicing is a condition.
From one of our customers
“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.”
