For landlords and property managers
The F-gas rules share responsibility for leak checking between the equipment’s operator and the service technicians. In a let or managed building, it’s worth agreeing who that operator is and we’re happy to deal with whoever it is.
If you look after several properties, we can plan visits across the portfolio and price them together. Each property gets its own records, so the files stay tidy.
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 the rest is down to us. Before we leave, the area is tidied and we explain what we have done. Pictures of the space and where the outdoor unit could go let us plan the work in Duncton.
- You tell us about the building and what’s needed.
- We survey the site to check heat gains, layout and access.
- We set out the options, the price and the programme.
- We install around your hours, phased where needed.
- We commission it, hand it over and can set up a maintenance contract.
Before we arrive
- Find the manual or the paperwork for the system, if you have it
- Clear a path to the units and the space around them
- Keep pets and children away from the work area
How to get a quote
Every quote starts with a look at the job, either on a site survey or, for simple jobs, from your pictures and details. After that, we send a fixed price so you know the cost before we begin.

Your questions about commercial air conditioning in Duncton
Is Duncton in your area for commercial air conditioning?
Yes. Duncton is one of the places we cover. To start, phone us on 07833 053749, or email if that’s easier with a few pictures.
Can I fit air conditioning in Duncton without planning permission?
It depends on the property. Historic England lists about 28 buildings and structures within half a mile of the centre of Duncton. 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 normally the planning authority for Duncton.
Does servicing affect my warranty?
Check the manufacturer’s terms. Some manufacturers make regular servicing by a qualified engineer a condition of the warranty, so check the terms or ask us. Keep every service record either way.
Can you set up regular servicing?
Yes. Maintenance contracts are part of what we do, with visits at the interval your system and the manufacturer need. Every visit is recorded, with F-Gas records where refrigerant work is involved.
How does the warranty work?
Warranty is the manufacturer’s own, on its terms. Each brand sets its own conditions and periods, so we explain them on your quote.
Will you work on another installer’s system?
Yes. Systems fitted by other companies are fine, on all the main brands. Send us the make and model, and any records you have.
Is there a survey before the work?
Yes, always. We diagnose before we treat: the survey tells us what the job needs and how to do it and the fixed price is built on it.
Why it’s worth doing now in Duncton
Small faults in a commercial system can spread to the whole building’s comfort. Planned maintenance catches issues before they grow and keeps the building comfortable. Booking before summer means the work in Duncton is done before the hot weather.
Putting the work off seldom saves money. Faults and wear in a system tend to grow, and a system working harder than it should costs more to run. If you’re not sure what’s needed, phone 07833 053749, or email if that’s easier and we’ll give you an honest view and a fixed price.
Why us?
- Every job looked at before it’s priced
- Fixed-price quotes after a survey or pictures
- MCS certification for heat pump work
- F-Gas company certification

Business air conditioning in Duncton
There are about 3 cafés, restaurants and staff canteens within about 1.5 miles of central Duncton, according to the Food Standards Agency’s register. Many of those sites need air conditioning that’s sized for long hours and maintained on a schedule.
Clinics, dental practices and pharmacies around Midhurst Community Hospital (about 5.4 miles north-west) typically want quiet indoor units with filters that are simple to keep clean. Churches and halls such as Church of Holy Trinity are often used a few hours at a time, which suits a system that heats or cools a space quickly, once consents are in place.
