When to call us in Chichester
Many people try a portable unit first. A portable unit has to vent its warm air through a hose out of a window, which lets some heat back in, and its compressor sits in the room with you. A fixed split system puts the compressor outside.
Look out for any of the following:
- An ageing air conditioning system near the end of its life
- A study or office that overheats during the day
- A portable unit with a hose out of the window
Plenty of people near Chichester station split the week between the train and a spare room, and that spare room is often the first to get a unit.

How we handle air conditioning in Chichester
We install leading brands, including Mitsubishi Electric, Daikin, Fujitsu, Panasonic, Toshiba, LG, Samsung, Mitsubishi Heavy Industries and Hitachi. We recommend a model on the survey and explain why it suits the room, and the manufacturer’s warranty terms are set out on your quote. Most split systems we fit in Chichester are reversible: the Energy Saving Trust notes that air-to-air heat pumps are sometimes called air conditioning, which is why many owners use theirs all year.
Air conditioning in a town like Chichester typically means a house, sometimes a flat or a converted building in the centre. The usual starting point is the hottest bedroom, a home office or a conservatory, with more rooms added on a multi-split if needed.
Think of the paperwork as the system’s health record: what was fitted or found, what was done and when. It makes the next visit quicker and any warranty question simpler and it’s worth keeping safe.

What happens on the day
The visit has three parts, a bit like a doctor’s appointment: diagnose, treat and sign off. First comes a careful look at the system or the space, then we do the work, and finally we test, record and explain. The middle part takes longest, and that takes a day for most single-room installations, with multi-split, ducted and cassette systems taking longer. A visit in Chichester is booked for a time that suits you.
- We survey the property, or work from your pictures for a simple job.
- The system is sized, positions are agreed and the price is fixed.
- Sheets go down first, then the indoor unit and the condenser are mounted.
- Pipework, cable and drain are run, the circuit is connected and the pipework is pressure tested and evacuated.
- The system is commissioned, the controls explained and the F-Gas records handed over.
How to prepare
- Tell us about access, such as roof hatches, high walls or locked plant areas
- Arrange for someone to be there to let us in
- Let us know where we can park and unload
How to get a quote
Some jobs can be priced from pictures, while others need a survey. Multi-room systems, commercial buildings and anything with a long or hidden pipe route are normally surveyed first. Either way, the quote is fixed before anything goes ahead.

One of our jobs in Chichester
East Street, Chichester (PO19)
- Property
- A ground floor independent restaurant within the roman city walls.
- Work carried out
- Installation of a Daikin wall-mounted unit in the dining area and a second unit serving the kitchen pass area. The listed building setting required a pre-application planning discussion, which confirmed that the outdoor unit could be positioned in the internal courtyard accessed from the rear lane. All external fixings used lime mortar-compatible fixings to protect the historic masonry.
- Outcome
- The restaurant owner reported that summer covers had increased as diners were no longer deterred by the heat, and that kitchen staff turnover: which had been attributed partly to heat stress: had reduced in the year following installation.

More services for Chichester
Different systems, different jobs
Outdoor unit positions
Outdoor units are fitted on wall brackets, at ground level or on a flat roof, whatever suits the building and the route. It needs airflow around it and room for servicing.
Pipework and condensate drains
Cooling produces water as the air is dried, which the condensate drain takes away. Where it can’t fall naturally to a drain, a condensate pump lifts it and we allow for that in the quote.
Leave it or put it right?
Fans and portables move warm air around rather than removing it. A fixed system removes the heat to the outside, runs more quietly in the room and can normally heat as well, so it works for you in winter as well. In a town like Chichester, the first hot week of the year is when most people call, so booking early helps.
Putting several jobs into one visit often makes better use of the time. Tell us about everything you’d like looked at, and you will get one fixed price.

FAQs for Chichester
Can I fit air conditioning in Chichester without planning permission?
It comes down to the building and the spot chosen for the outdoor unit. The Chichester Conservation Area takes in the middle of Chichester. 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 typically the planning authority for Chichester.
How do I get a quote for air conditioning in Chichester?
Send us photos of the room or the system and a few details about the property. Where photos are not enough, a survey comes first and the fixed-price quote follows.
Is the equipment covered by a warranty?
It’s the manufacturer’s, and the terms are theirs. Some terms depend on regular servicing by a qualified engineer, so keep your service records.
Can you fit air conditioning in a leasehold flat?
Often, yes, but there are extra steps. Leaseholders normally need consent from the landlord or management company for an outdoor unit and holes through outside walls, so check the lease. Permitted development rules for flats are also tighter than for houses, and we flag anything that may need permission. This is general information, not legal advice.
How long does air conditioning installation take?
Most single-room systems take a day. Multi-split, ducted and cassette systems take longer and the quote says how long to expect.
Where does the outdoor unit go?
The position is agreed on the survey, not on the day. It must have clear airflow and space for servicing, and walls or roofs facing a road can raise planning questions. We explain the options and any permissions to check.
Are you F-Gas certified?
We hold F-Gas company certification, which the law requires for any business working on refrigerant. NICEIC approval, MCS certification for heat pumps and Checkatrade membership sit alongside it.
