South Mundham air conditioning
Supply, installation and commissioning of air conditioning for homes and businesses, from one room to a whole building, for South Mundham and the surrounding area. Call for a fixed-price quote; we reply the same working day.
- A room that’s unbearable on warm days
- A system on old refrigerant that’s due for replacement
- Working from home in a room that gets too warm
When something else is needed
Some problems need a different service or another trade:
- Damp from leaks or a lack of ventilation
- Heat loss through very poor insulation (a system will heat the room, but insulation is a separate job)
- Work that needs permission from a landlord or the council
If in doubt, phone us on 07833 053749 or email us and we will say what we think before you book.

Air conditioning in South Mundham, done properly
Across South Mundham, every installation follows the same steps: survey, fixed-price quote, a neat installation, full commissioning and the F-Gas paperwork. You know the price before any work starts and the paperwork is in your hands when we finish. Every installation in South Mundham begins with a look at the rooms, the walls and where the outdoor unit can go, then a fixed-price quote that names the make and model.
A typical install in South Mundham 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.
Homes around South Mundham normally have room outside for an outdoor unit. More often it’s the walls, the electrics and the length of the pipe run that need thinking about.
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. For any other brand, we explain the manufacturer’s terms on your quote.

Homes in South Mundham and air conditioning
At about 2 miles from the coast, South Mundham is close enough for sea air to matter. Some manufacturers offer anti-corrosion coated coils for coastal sites, and we will tell you if the model you choose has that option. On the National Heritage List, around 5 entries fall within 0.5 miles of the middle of South Mundham; South Mundham Farmhouse (grade II*) is one. If your property is listed or sits inside a conservation area, expect us to raise planning at the survey and to speak to Arun council, usually the planning authority here where it’s needed. The Valuation Office Agency’s council tax figures date about 56% of homes in South Mundham and the neighbourhoods around it to the post-war years, 1945 to 1972, and the last census (2021) found about 72% of households in detached or semi-detached houses. We check the wall construction on homes of that age, as it decides how the pipework goes through. 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. Living close to The Parish Church of St Stephen? Some older properties in parts like that are protected, and the survey finds out whether yours is.

All of PO20 is within our area. If you need air conditioning at a property on Manor Lane and Honer Lane or a nearby road, our engineers can take on the work. If you’re just outside South Mundham, we cover Fisher (1 mile west), Street End (2 miles south-west), Sidlesham Common (2 miles west), Nyetimber (2 miles south-east) and Sidlesham (2 miles south-west). We also work in nearby towns such as Bognor Regis (3 miles east), Chichester (3 miles north), Selsey (5 miles south) and Littlehampton (10 miles east).
Local landmarks in South Mundham
Around South Mundham, our work takes us to homes and businesses near Chichester High School For Girls and Avisford. The nearest railway station is Chichester station, roughly 2.5 miles north-west of the centre. Nearby you will also find Chichester Castle (3 miles north) and Chichester Cathedral Treasury (2.7 miles north-west).
Looking after it afterwards
How well a system lasts depends on use and care. Here’s what we suggest:
- Do not cover or box in the outdoor unit
- Keep the F-Gas records, commissioning details and warranty information together
- Report drips, noises or error codes right away
Before we leave, the system is commissioned and tested in each mode. Once it’s running properly, we take you through the controls and settings so you know how to get the best from it.
Have the system serviced once a year. A service cleans what you cannot reach and picks up faults before they stop the system and keeps the warranty paperwork right where servicing is a condition.
South Mundham questions
Will you come out to South Mundham?
Yes. South Mundham is within the area we cover across London and the South East. Visits to smaller places are planned so the engineer arrives with what the job needs.
Is the coast a problem for outdoor units in South Mundham?
It can. South Mundham is within about 2 miles of the coast, and salt air speeds up corrosion on outdoor units. The outdoor unit position, its fixings and regular servicing all help near the sea.
How long does air conditioning installation take?
It takes a day or more, depending on the number of rooms, the pipe routes and the access. We confirm the time when we quote, so you can plan around it.
Do you protect the property while you work?
Protection goes down first: dust sheets over floors and anything close to the work. Any drilling is agreed with you first, and we clear up the dust and offcuts when we finish.
Is air conditioning possible in a flat?
It depends on the building and the lease. An outdoor unit can sometimes go on a balcony, roof or rear wall, with consent and the survey looks at every option. This is general information, not legal advice.
Do you offer maintenance contracts?
Yes. Tell us what you have and how it’s 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.
Can air conditioning heat my home as well?
Yes, most modern split systems run as heat pumps, so they heat as well as cool. The Energy Saving Trust points out that an air-to-air heat pump is often just called air conditioning. We confirm the heating function of the model we quote.
Rented and managed buildings
Records are where property maintenance often slips. Each visit produces a dated record, plus the F-Gas records where refrigerant is involved, so you can show what was done and when.
Where a tenant occupies the property but the landlord owns the system, the lease or tenancy agreement normally sets out who maintains what. We’re happy to deal with either side and send the records to whoever needs them.
How the visit works
Testing is the last part of the visit wherever the system can be switched on. Then we explain what was done and answer your questions, and anything that needs a follow-up is pointed out there and then. All told, the work takes a day for most single-room installations, with multi-split, ducted and cassette systems taking longer. We agree a date with you and plan the visit to South Mundham so we arrive with what’s needed.
- First the diagnosis: a survey of the rooms, the walls, the outside and the electrics.
- Next, a recommendation for each room and a fixed price.
- The treatment: units fitted, pipework and drain routed, and the electrics installed.
- Before it runs, the pipework is proved tight and put under vacuum.
- The sign-off: commissioning, a walk through the controls, and the F-Gas records and warranty details.
Before we arrive
- Plan for pets to be kept clear during the visit
- Make sure we can reach the consumer unit or fuse board
- Move furniture away from the wall where we will be working
How to get a quote
Here’s what helps us quote: the address and the type of property, photos of the rooms or units, the make and model of any existing system and anything you’ve noticed, such as an error code or a noise. Then phone us on 07833 053749.

“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.”
