Common questions in Trotton Marsh
Is Trotton Marsh within the area you cover?
Yes, and the size of the place makes no difference to how we work. Send a few details and photos, and we reply the same working day.
Is planning permission needed for air conditioning in Trotton Marsh?
It comes down to the building and the spot chosen for the outdoor unit. Historic England lists about 5 buildings and structures within half a mile of the centre of Trotton Marsh. 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, typically the authority for Trotton Marsh when it matters.
Do you look at the job first?
Yes. Every job is looked at first, either on a site survey or from photos and details for simple jobs. A fixed-price quote follows.
Do you offer maintenance contracts?
Yes. Send details of the systems and how they’re used, and we’ll suggest a schedule with a fixed price. That can include the leak checks the F-gas rules require for larger systems.
Do you offer emergency call-outs?
Yes, any time. For anything urgent, such as a system failing in a server room or water leaking from a unit, ring our 24/7 line and we’ll agree what happens next.
How long will the installation take?
A single-room system is typically fitted in a day. Multi-room and ducted systems take longer, depending on the pipe routes and access and the quote says how long to expect.
Who is responsible for leak checks?
The F-gas rules share it between the equipment’s operator and the engineers who work on it. The interval depends on the refrigerant charge, measured in tonnes of CO2 equivalent: at least yearly for 5 to under 50 tCO2e, and every 6 months for 50 to under 500 tCO2e.

Nothing is signed off by word of mouth: commissioning details for an installation, a fault and repair note for a repair, or a record of the service. File it with the manual, because it helps with any later warranty question.

Air conditioning around Trotton Marsh
About 41% of homes in and around Trotton Marsh were built before 1919, according to VOA council tax data, and the last census (2021) found about 82% of households in detached or semi-detached houses. Older homes often have solid walls, which take longer to core drill, so we plan pipe routes carefully and keep them as discreet as we can. 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.
A loft bedroom or a glazed extension is often the room that prompts the first call. Cowdray House, about 4.2 miles south-east, is one of the historic houses nearby, and if your own home is listed, consent comes before any air conditioning is fixed to it.

How the job changes from property to property
Pipework and condensate drains
The indoor and outdoor units are joined by insulated refrigerant pipes, a cable and a condensate drain. The route is agreed before any drilling and kept as tidy as the building allows.
Ducted systems
Ducted units can feed several rooms through a network of ducts, and they’re easiest to fit while ceilings are open, such as during a refurbishment.
After we’ve gone
To keep the system working properly:
- Keep the room closed while it runs
- Have the system serviced once a year
- Keep the F-Gas records, commissioning details and warranty information together
If anything is not right after we have gone, call us on the same number. Tell us what the system is doing, and any code on the display, and we’ll talk it through with you.
Regular filter cleaning is the simplest thing you can do. Clean filters keep the air moving and help the system work as designed, so it uses less electricity for the same comfort.

What owners can safely do
For air conditioning, cleaning the indoor unit’s filters is the main job owners can do, if the manual says so. With the power off, they lift out, can be vacuumed or rinsed and must be fully dry before they go back. For a heat pump, the main owner jobs are a clear outdoor unit and sensible control settings.
Good habits make our visits easier, not unnecessary. Simple care keeps the air moving through the system, but the refrigerant circuit, the electrics and the parts you can’t see still need an engineer at the interval the manufacturer recommends.
The process
On the day, we arrive at the time agreed with you and run through the plan before anything else. Dust sheets go down over floors and anything close to the work, and the electrics are made safe before any panel comes off. The work itself takes a day or more, depending on the number of rooms, the pipe routes and the access. Seeing the property in pictures first means the trip to Trotton Marsh can be planned properly.
- We survey the property, or work from your pictures for a simple job.
- Each room is sized and the unit positions agreed, then you get a fixed-price quote.
- Sheets go down first, then the indoor unit and the condenser are mounted.
- We run and connect the pipes, cable and drain, then pressure test and evacuate the circuit.
- We commission, show you the controls and leave the F-Gas and warranty paperwork.
Preparing for the visit
- Find the manual or the paperwork for the system, if you have it
- Unlock any gate, garage or side passage we need
- Mention any roof access, ladders or high-level work
