Commercial air conditioning in Thorney Island
Commercial air conditioning is a big part of what we do, for businesses in Thorney Island and the rest of West Sussex. That includes offices, shops, restaurants, hotels, schools and server rooms, and each one gets a system chosen for how the space is used. Common call-outs are for systems that need out-of-hours or phased installation and leak check schedules that have slipped, across ceiling cassettes, wall-mounted split systems and VRF systems.
For a business near Thorney Island, outdoor units typically have room at the back of the building.
Whatever the visit, you get a written record: commissioning details and F-Gas records for a new system, a note of the fault and the fix for a repair, or a service record. File it with the manual, because it helps with any later warranty question.

Your questions about commercial air conditioning in Thorney Island
Does sea air affect air conditioning in Thorney Island?
It can, as Thorney Island is within about 1 mile of the sea, where salt in the air is hard on coils and fixings. We site outdoor units out of the worst of the sea wind where possible and can suggest models with corrosion protection where the manufacturer offers it.
Can you do commercial air conditioning in Thorney Island?
Yes, Thorney Island is within the area we cover. To start, phone 07833 053749 or fill in the contact form with a few photos.
What does F-Gas certified mean?
Certification shows a business is approved to work on systems that hold F gas refrigerant. That is not optional: it’s required by law, and AirCon Doctor is certified.
How much time does a commercial air con install need?
An installation takes from a couple of days for a few cassettes to a planned programme for a whole building. We confirm the timing after the survey, and you can call 07833 053749 or fill in the contact form to book it.
Do you work for landlords and businesses?
Yes. Homeowners, landlords, agents and businesses all book us across London and the South East. Tell us who should receive the paperwork.
Which commercial systems do you fit?
Wall-mounted, cassette, ducted, multi-split and VRF or VRV systems. The right one depends on the building and how it’s used.
How often is a TM44 inspection needed?
The threshold is 12 kW of effective rated output, with inspections at least every 5 years. An accredited energy assessor does the inspection, and we can carry out the recommended work.
Owner checks or an engineer?
Never try to top up, release or handle refrigerant yourself. Under the F-gas rules, engineers need their own qualifications and the company must be certified, and escaping refrigerant can cause cold burns. A suspected leak is our job, not yours.
Good habits make our visits easier, not unnecessary. Clean filters and a clear outdoor unit help the system run as it should, but the refrigerant circuit, the electrics and the parts you cannot see still need an engineer at the interval the manufacturer recommends.

Different systems, different jobs
Ducted systems
A ducted system hides the indoor unit and feeds air to the room through grilles. They’re chosen where appearance matters, such as hotels, restaurants and shops.
Server and comms rooms
Server rooms generate heat all day and night and the cooling must keep up all year. We size the system on the heat load.
The process
Think of the visit in three stages: diagnose, treat and sign off. First we check the system or the space against the plan, then the work itself, and finally we test, record and explain. The middle part takes longest, and that takes from a couple of days for a few cassettes to a planned programme for a whole building. Photos of the existing unit help with repairs and servicing in Thorney Island.
- First comes a survey, looking at the building and how it’s occupied.
- We recommend a system and send a fixed-price quote.
- We agree the timing, with evening, weekend or phased work as needed.
- We install the units, pipework, drainage, electrics and controls.
- Commissioning and handover follow, with the F-gas records and manufacturer paperwork.
Preparing for the visit
- Make sure we can reach the consumer unit or fuse board
- Mention any managing agent or landlord rules we need to follow
- Clear the space around the indoor unit, or where it will go
Getting a quote
VAT is set out clearly on every quote, and the rate that applies to your job is stated. VAT can differ between homes and businesses and between kinds of work, so we confirm it on the quote. For a fixed-price quote, call us on 07833 053749 or fill in the contact form.
Advice
What affects the quote in Thorney Island
The quote reflects the job in front of us. We take into account:
- One-off work versus a regular service cycle
- How easy the units are to reach
- How far the pipework has to run, and where
No two properties are the same, so we price each one individually. The system, the access, the pipe routes and the parts involved all make a difference.
Asking for a quote
What to send for a quote:
- Wide photos of the room or the existing unit
- Where the outdoor unit is, or where you’d like it
- The remote or wall controller showing any error
Published ranges are a starting point; the quote is built on your property, because every property is different. Once we have looked at the job, from pictures or on a survey, you get a fixed price. To start, give us a ring on 07833 053749 or use the quote form.
