Air con installers in Selham
Need air conditioning in Selham? We diagnose first, fix the price and book the work around you, finishing with proper records.
- A system on old refrigerant that is due for replacement
- Bedrooms and offices that overheat in summer
- Not knowing which system, size or brand to choose
What you can do yourself, and what needs us
Refrigerant is off limits for anyone without the right qualifications. The law requires anyone working on equipment containing F gas to hold the right qualifications, and the company to be certified, and refrigerant lines can cause cold burns. A suspected leak is our job, not yours.
For air conditioning, cleaning the indoor unit’s filters is the main job owners can do where the manufacturer’s manual explains how. They come out, get a gentle clean and go back only when they’re dry. On a heat pump, the equivalent is keeping the outdoor unit clear and checking the controls.
Air conditioning for homes and businesses in Selham
Good air conditioning starts with the right system in the right place. We look at each room’s size, glazing, orientation and use, and we agree the unit positions and the route for the pipes, cable and drain before you get a fixed-price quote.

Planning permission isn’t usually needed for a house if the unit qualifies as permitted development, but listed buildings, conservation areas and flats often need consent first: we tell you at the survey if it applies.
Homes around Selham usually have room outside for an outdoor unit. The questions are more often the age of the walls, the electrics and how far the pipes need to run.
Some manufacturers make regular servicing by a qualified engineer a condition of their warranty. If that applies to your system, booking the service on time keeps the record straight, and every service is written up.

Questions from Selham
Will air conditioning in Selham need planning permission?
The answer turns on the property and where the outdoor unit would sit. The centre of Selham is in the Selham Conservation Area. Put simply: reversible systems on houses can be permitted development, cooling-only ones cannot, listed buildings need consent, and conservation areas limit outdoor units facing a road. When your property needs a decision, we contact Chichester council, which is normally the planning authority for Selham.
Will you come out to Selham?
Yes, and the size of the place makes no difference to how we work. Visits to smaller places are planned so the engineer arrives with what the job needs.
How do you size the system?
It depends on the room, not only its floor area. Glazing, orientation, the roof and what goes on in the room all affect it, and we take them all into account on the survey.
Do I need a new electrical circuit?
Most systems need their own supply from the consumer unit. Under Part P, a new circuit has to be notified unless a registered competent person does it, and as NICEIC approved contractors we install and certify it as part of the job.
What does it cost to install air conditioning?
For one room, a 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.
Which type of system should I choose?
Number of rooms, space outside and how much of the unit you want to see all decide it. Ducted units need a void or loft, and cassettes need a suspended ceiling and the survey confirms what’s possible.
Who has to arrange F-Gas leak checks?
Whoever operates the equipment, together with the technicians who service it. Larger systems need regular checks: at least every 12 months from 5 tCO2e and every 6 months from 50 tCO2e. We can tell you which band your system falls into.
How the visit works
The work area is kept tidy throughout, with dust sheets down and offcuts and packaging cleared up. If we need to drill through a wall, we agree the spot with you first. The visit takes a day or more, depending on the number of rooms, the pipe routes and the access. Photos of the existing unit help with repairs and servicing in Selham.
- We survey the rooms and the outside of the property, or work from pictures and details for simple jobs.
- The quote is fixed and shows the equipment, where each unit goes and what’s included.
- The units go up and the pipework, cable and condensate drain are run neatly between them.
- Once the electrics are connected, the pipework is tested for leaks and put under vacuum before any refrigerant flows.
- Finally, it’s commissioned, tested in each mode and handed over with the F-Gas records.
Before we arrive
- Let us know where we can park and unload
- Dig out any previous service or F-Gas records
- Give us access to the outside wall, roof or yard where the outdoor unit sits

Advice
Do you need air conditioning in Selham?
Commercial spaces gain heat from people, equipment, lighting and glazing. Keeping staff and customers comfortable is normally what prompts the call, along with keeping equipment rooms at a steady temperature.
Customers normally contact us after spotting one of these:
- Not knowing which system, size or brand to choose
- Old electric heaters you’d like to replace with something more efficient
- A home office that warms up with screens and equipment
Around Church of St James, a quick check of the listing and conservation maps is part of planning any install.
What to look for in a quote
- Whether they looked at the job before pricing it
- Whether a new circuit is included and who certifies it
- What happens if the job turns out to be different on the day
Why it’s worth doing now in Selham
Size matters more than brand. An undersized unit runs hard and still cannot keep the room cool; too big, and it switches on and off and wastes energy. Sizing each room properly on the survey avoids both. Getting the date in early helps for a place like Selham.
Putting several jobs into one visit can make for a more efficient booking. Tell us about everything you’d like looked at and we will price it together.

Air conditioning around Selham
The Valuation Office Agency’s council tax figures put about 43% of homes across Selham and its surrounding area before 1919, and the 2021 Census found about 73% 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. A side passage or back wall normally gives the outdoor unit a home, and more than one bedroom can be cooled through a multi-split.
Cowdray House, about 2.7 miles west, is one of the historic houses nearby, and if your own home is listed, consent comes before any air conditioning is fixed to it.

A customer’s words
“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.”
