Questions from Hunston
Does sea air affect air conditioning in Hunston?
It can. Hunston is within about 3 miles of the coast, and salt air speeds up corrosion on outdoor units. The outdoor unit position, its fixings and regular servicing all help near the sea.
Is planning permission needed for air conditioning in Hunston?
That depends on the building and where the outdoor unit goes. Central Hunston is a short walk from the Hunston Conservation Area. Permitted development only covers heat pumps that aren’t used solely for cooling, and not within the grounds of a listed building. Conservation areas add limits on outdoor units facing a road. Where needed, we check with the local planning authority (for Hunston, usually Chichester council).
Can we book visits on a schedule?
Yes. Tell us what you have and how it’s used and we will propose a schedule and quote for it. Leak checks required by the F-gas rules can be built in for larger systems.
Do I need to service the system to keep the warranty?
That depends on the brand. If servicing is in the terms, missing one could affect a claim, so we explain the terms on your quote.
Can you look at a system you didn’t fit?
Yes. We look at it first and tell you what we find, including anything about the original installation that needs putting right. Any work is priced before it goes ahead.
Can I do any of the installation myself?
Anything that involves the refrigerant needs an F-Gas qualified engineer from a certified company. That’s a legal requirement, and manufacturers expect it for their warranty too. We can quote for the whole job, from supply to commissioning.
When will I hear back?
On the same working day you contact us. After that, we agree a survey, diagnosis or installation date that suits you, and you get a fixed price before any work goes ahead.
About our commercial air conditioning in Hunston
Once a system is in, it needs looking after. Maintenance contracts cover servicing, F-gas leak checks and the records that go with them with the cost agreed up front. There’s a 24/7 emergency line for breakdowns. The work covers ducted systems, multi-split systems and server and comms room cooling, and the jobs we see most are fit-outs and refurbishments that need new air conditioning and ageing air conditioning that keeps breaking down.
Around Hunston, there’s typically space for outdoor plant away from the road, out of sight and away from neighbours.
Refrigerant work is written up in the F-Gas records: the work carried out, the refrigerant involved and the quantities. Keep the records with the manual and the warranty documents, as a manufacturer or a future engineer may ask to see them.

What we’re called out for in Hunston
Restaurants and hotels need comfortable rooms for guests and staff. Each area has its own hours and heat load, which affects the type of system and controls we’d suggest.
Any of these is worth a proper look:
- Ageing air conditioning that keeps breaking down
- Changes of use that need a new layout
- Planning ahead for the HFC phase-down
If you look after a school such as North Mundham Primary School, classroom, office and IT room cooling is typically installed in the holidays.

The process
There’s very little for you to do on the day. Just let us in and point us to the units, or to where they’ll be fitted, and we take it from there. Before we leave, the area is tidied and we explain what we’ve done. Photos of the room and the outside of the property help us plan a visit to Hunston.
- We start with the details of the building and the problem.
- We survey the site to check heat gains, layout and access.
- The options, cost and timing are set out in a fixed-price quote.
- We install around your hours, phased where necessary.
- The system is commissioned and maintenance can be arranged.
Preparing for the visit
- Tell us about access, such as roof hatches, high walls or locked plant areas
- Let us know if the building has a permit or sign-in process
- Let us know where we can park and unload
Ask for a quote
Photos are enough for some jobs; others need a visit first. Bigger systems, commercial sites and awkward pipe routes are normally surveyed on site. Either way, the quote is fixed before anything goes ahead.
