Air conditioning near Hunston

How we handle air conditioning in Hunston

We fit wall-mounted splits, multi-split systems, ducted systems and ceiling cassettes, with VRF for larger buildings. Which one suits you depends on the space, the building and how much of the unit you want to see, and we explain the options on the survey. Every installation in Hunston 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.

Planning permission isn’t normally needed for a house if the unit qualifies as permitted development, but listed buildings, conservation areas and flats need more care: we tell you at the survey if it applies.

Space outside is rarely the problem in a place like Hunston. The questions are more often the age of the walls, the electrics and how far the pipes need to run.

Refrigerant work is written up in the F-Gas records: the work carried out, the refrigerant involved and the quantities. File them with the system’s paperwork, as a manufacturer or a future engineer may ask to see them.

When it’s something else

We’d rather tell you now than sell you work that won’t help, so these are the things it won’t cover:

  • Central heating repairs
  • A lack of fresh air (most split systems recirculate room air rather than bringing fresh air in, which is a job for ventilation)
  • Work that needs permission from a landlord or the council

If you are not sure, just phone 07833 053749, or email if that’s easier and we will give you a straight answer before booking.

What we work on in Hunston

  • VRF systems

What an install looks like in Hunston

Hunston lies within about 3 miles of the sea. Near the sea, outdoor unit position matters more: sheltered from salt-laden wind where possible, on fixings that won’t rust. The Valuation Office Agency’s council tax figures show about 34% of homes in and around Hunston were built in 2000 or later. Newer homes normally have cavity walls and loft space that make pipe runs easier, though some estates have planning conditions or covenants worth checking.

Older streets near St Leodegar's Church may fall within a conservation area, so we check the planning position before choosing where the outdoor unit goes.

Hunston is about 2 miles south of Chichester, in West Sussex. From the centre of Hunston to the outskirts, our engineers cover air conditioning, from a single room to a whole building. Across West Sussex, we cover 371 places, Hunston among them. The nearest of our city pages is Worthing, around 17 miles from Hunston.

Our nearest recent job to Hunston was on East Street, Chichester (PO19), about 2 miles north: installing a Daikin wall-mounted unit in the dining area and a second unit serving the kitchen pass area. More about it

Our engineers work on Heath Close, Westlands Road and St Leodegars Way and the roads around them. Every address in PO20 is within our area, from busy streets to back roads.

Hunston questions

Will you come out to Hunston?

We do. Villages and hamlets get the same service as the bigger towns. Send a few details and photos, and we reply the same working day.

Can I fit air conditioning in Hunston without planning permission?

The answer turns on the property and where the outdoor unit would sit. There’s a conservation area, the Hunston Conservation Area, close to central Hunston. A system that heats as well as cools may not need an application on a house, provided it stays within the permitted development limits. Cooling-only units get no such allowance, and listed buildings and road-facing positions in conservation areas need more care. We speak to the planning department at Chichester council, usually the authority for Hunston when it matters.

Will I get records for the system?

Yes. It’s the record a manufacturer or the next engineer will ask to see: the date, the work, and any refrigerant added or recovered.

Does servicing affect my warranty?

It depends on the manufacturer’s terms. Some manufacturers make regular servicing by a qualified engineer a condition of the warranty, so it’s worth checking. Either way, keep a record of every service.

How do I know what size unit to get?

Floor area is only part of it. Glazing, orientation, the roof and what goes on in the room all affect it, and we take them all into account on the survey.

Will you need to do electrical work?

Usually, yes. We check your consumer unit on the survey and include any electrical work on the quote, and our NICEIC approval covers the installation and certificate.

Do you work on all makes?

We install and work on the leading makes, including Mitsubishi Electric, Daikin, Fujitsu, Panasonic, Toshiba, LG, Samsung, Mitsubishi Heavy Industries and Hitachi. Tell us the make and model and we’ll take it from there.

What we are called out for in Hunston

Poor sleep is one of the most common reasons homeowners ask about air conditioning. An open window doesn’t always cool a bedroom that has warmed up all day, particularly when there’s no breeze.

The things we are asked about most are:

  • Expensive direct electric heating
  • Uncertainty over the right type and size of system
  • Working from home in a room that gets too warm

Goodwood House, about 4.5 miles north, is one of the historic houses nearby, and if your own home is listed, consent comes before any air conditioning is fixed to it.

What to look for in a quote

  • Whether extra work needs your approval first
  • Whether the manufacturer’s warranty depends on regular servicing
  • Whether testing, commissioning and paperwork are included

Questions to ask before you book

How it works

Each visit runs to the same pattern: check the plan with you, put the dust sheets down, carry out the job, check the system and explain it all to you. On site, the work takes a day for most single-room installations, with multi-split, ducted and cassette systems taking longer. If a lane or gateway near Hunston is tight for a van, let us know and we’ll plan for it.

  1. Diagnosis comes first, with a survey of the rooms, outside space and fuse board.
  2. Then the prescription: the right system and size for each room, on a fixed-price quote.
  3. The treatment: units fitted, pipework and drain routed, and the electrics installed.
  4. Testing: the circuit is pressure tested and evacuated before the refrigerant is released.
  5. Finally, the clean bill of health: commissioning, the controls explained and your paperwork handed over.

Before we arrive

  • Tell us about access, such as roof hatches, high walls or locked plant areas
  • Clear a path to the units and the space around them
  • Tell us about parking and loading

Ask for a quote

For a fixed-price quote, ring us on 07833 053749 or drop us a line and tell us about the property and what you need. A few pictures make it quicker. You will hear back from us the same working day.

What the work involves, system by system

Ducted systems

Ducted air conditioning hides the indoor unit in a ceiling void or loft, and all you see is a discreet grille. It suits rooms where a visible unit wouldn’t work.

Offices, shops and commercial rooms

Bigger systems in buildings come with extra duties, including a TM44 inspection by an accredited energy assessor at least every 5 years. We can arrange and prepare for it.

What a customer said

“Very professional from the initial survey through to installation. The engineer explained everything clearly and the quote was exactly what we paid. Would not hesitate to recommend AirCon Doctor.”
