Air Conditioning Services Across Sussex
Seven services from one family run company, established in 2010: installation, commercial work, repairs, servicing, planned maintenance, air handling and mechanical assembly, across Sussex, Surrey and Lincolnshire.
Seven Services From One Company
JAC Air Conditioning Ltd is a family run air conditioning company, established in 2010, with an office in Horsham serving Sussex and Surrey and a base at Fosdyke serving Lincolnshire. We design, install, service and repair air conditioning for homes and businesses, and look after the larger plant that commercial buildings rely on. Our engineers install systems from Mitsubishi Heavy Industries, Mitsubishi Electric, Daikin, Fujitsu, GENERAL, Samsung and LG, and we service and repair every major brand, not only the ones we fit.
For a house, a bungalow, a park home or a garden room, domestic air conditioning installation covers single split, multi split and ducted systems, sized to the room and commissioned properly. Offices, shops, bars, hospitality venues, gyms, server rooms and industrial units are covered by commercial air conditioning, designed and installed around trading hours.
When a system stops cooling, leaks water or shows an error code, our air conditioning repairs service diagnoses the fault on any make and prices the repair before work begins. To stop faults happening in the first place, air conditioning servicing cleans and checks each system and leaves a written record, which manufacturers usually ask for to keep the warranty valid.
What Are You Cooling?
It comes down to the room, the ceiling, how often the space is used and what you want to see on the wall. Here are the six systems we fit most often, and what each one suits.
Pick the space
Pick what you are cooling and the table shows what we would usually fit, and what else would work. Every system is still sized at a free survey before anything is quoted.
| System | Best for | On show | Install | Upkeep |
|---|---|---|---|---|
Wall Mounted Split Best FitAlso Suits | One room: a bedroom, home office, garden room or snug | A slim unit high on the wall | The simplest to fit: one unit inside, one outside | Filter clean, annual service |
Multi Split Best FitAlso Suits | Several rooms running off one outdoor unit, where outside wall space is tight | A unit in each room | A pipe run to each room from the one outdoor unit | One service covers the lot |
Ceiling Cassette Best FitAlso Suits | Offices, shops and bars with a suspended ceiling to sit the unit in | A flush panel in the ceiling | Needs a ceiling void | Filters dropped out in place |
Ducted Best FitAlso Suits | Whole floors and open plan, where nothing should show but the grilles | Grilles only; the unit sits above the ceiling | Planned into the build or a dropped ceiling | Filters and coil cleans |
Server Room Cooling Best FitAlso Suits | Server and comms rooms that need cooling in February as well as August | A unit of its own, often two so either can cover the other | Low ambient kit outside, so it cools in winter too | Checked more often, as it never stops |
Air Handling Unit Best FitAlso Suits | Ventilating a whole building rather than cooling one room | Nothing in the room but the diffusers | Plant room or roof, often craned in | Filters, belts and bearings |
How to Choose the Service You Need
What you need usually falls into one of three situations. If you do not have air conditioning yet, or want to add another room, start with installation for a home or commercial air conditioning for a business. If you have a system that is not working as it should, you need a repair. If your system works and you want it to stay that way, you need servicing for a single system, or planned maintenance for a business with several.
Businesses responsible for larger systems have legal duties as well as practical ones. A planned maintenance contract puts every unit on a schedule, carries out the F-Gas leak checks the regulations require, and keeps the records for you. Buildings that move fresh air through ductwork usually have an air handling unit, and our air handling service installs, maintains, repairs and refurbishes them, from filters and coils to fans, motors, belts, bearings and dampers. Where a project needs pipework built from scratch, mechanical assembly covers plant room pipework, manifolds and valves, brazed, pressure tested and insulated.
If you are comparing systems before you decide, our specification sheets page lists the manufacturers and ranges we install, with the data sheets for each one ready to download. If you are still unsure, call the office on 01403 733 492 and describe what you need. We will tell you which service fits and arrange a survey with Jay or Oscar.
Why One Team Does All of It
Many buildings end up with one company for installation, another for servicing and a third for the air handling plant, each with its own records and its own view of the problem. When something goes wrong, nobody has the whole picture. Because JAC carries out all seven kinds of work, the engineer who services your system knows how it was installed, and the records for every unit sit in one place.
It also means the work is done to one standard throughout. Pipework is brazed and pressure tested the same way for a single wall unit in a bedroom as for a plant room on a commercial roof. Every refrigerant circuit is handled under our REFCOM F-Gas company certificate, REF1019419, valid to 25 May 2028. Our engineers are CITB qualified and City and Guilds qualified and registered with the Construction Safety Scheme, and we are a Mitsubishi Heavy Industries 3 Diamond Dealer, which is MHI's top dealer level.
Being family run also means you deal with the same people from the first call to the last visit. Nicola runs the office and arranges appointments, while Jay and Oscar quote for the work and carry it out themselves.
Questions, Answered
Which areas do you cover?
JAC Air Conditioning Ltd covers Sussex and Surrey from our office on Worthing Road in Horsham, including Guildford, Godalming, Dorking, Brighton, Worthing, Chichester, Bognor Regis, Haywards Heath, Burgess Hill, Billingshurst, Cranleigh, Hassocks and Storrington. In Lincolnshire we work from our base at Fosdyke, covering Boston, Spalding, Sleaford, Grantham, Lincoln and the villages around them.
Do you work on air conditioning you did not install?
Yes. We install Mitsubishi Heavy Industries, Mitsubishi Electric, Daikin, Fujitsu, GENERAL, Samsung and LG systems, but we service and repair every major brand. If your system was fitted by another company, or the original installer is no longer trading, we can take it on, find out what we can about its history and put it on a regular servicing schedule.
Do you work for homes as well as businesses?
Yes. We fit air conditioning in houses, bungalows, park homes and garden rooms, and in offices, shops, bars, gyms, server rooms and industrial units. Installation, repairs and servicing are for homes and businesses alike, while planned maintenance contracts, air handling and mechanical assembly are mostly carried out for commercial buildings and the people who manage them.
Is the quotation free?
Yes. Every quotation is free and carries no obligation. One of our engineers surveys the room or building first, so the price is based on what is actually there, and you receive it in writing with the units named on it. That makes it straightforward to compare our price with any other quotation you are given.
Are you F-Gas certified?
Yes. JAC Air Conditioning Ltd holds a REFCOM F-Gas Stationary Equipment Qualification company certificate, number REF1019419, issued by Refcom Certification Ltd and valid to 25 May 2028. It covers all systems under or over 3 kg and hermetically sealed systems over 6 kg. Only a certified company may install, service or repair a refrigerant circuit.
