Commercial air conditioning in Crosspost: local notes
The FSA’s food hygiene register shows about 5 restaurants, cafés and canteens within 1.5 miles or so of the middle of Crosspost. Many of those sites need air conditioning that’s sized for long hours and maintained on a schedule.
If you look after a church or hall such as St Mary Magdalene's Church, an air-to-air system that warms up quickly can suit a building used on and off, subject to the right consents. If you look after a school such as Bolney CofE Primary School, classroom, office and IT room cooling is normally installed in the holidays.

Commercial air conditioning in Crosspost
We design, install and look after air conditioning for businesses in Crosspost and across West Sussex. That includes offices, shops, restaurants, hotels, schools and server rooms, and each one gets a system chosen for how the space is used. The work covers ducted systems, ceiling cassettes and server and comms room cooling, and common reasons people get in touch are changes of use that need a new layout and installs that must fit around trading hours.
For a hall or similar building near Crosspost, an air-to-air system that responds quickly suits intermittent use, and it can heat as well as cool.
Some manufacturers make regular servicing by a qualified engineer a condition of their warranty. If that applies to your system, booking the service on time keeps the record straight, and every service is written up.

Owner checks or an engineer?
Write down what you notice: an error code, a new noise, a drip, a smell or a change in how well the system heats or cools. It makes our diagnosis quicker, and a photo or a short video of the display is even better.
Do not move, re-route or disconnect units or pipework yourself. Moving a unit involves the refrigerant circuit, so it needs an F-Gas qualified engineer, and the electrics need care too. Ask us to quote for a move instead.
What air conditioning won’t do
An honest diagnosis matters more to us than a booking, so here’s what this work cannot put right:
- Boiler installation or repair
- Planning permission or landlord consent on your behalf
- Fire safety design or fire risk assessments
Not sure which it is? You can phone us on 07833 053749 or send an email and we’ll tell you honestly before booking.

FAQs for Crosspost
Is air conditioning in Crosspost permitted development?
It comes down to the building and the spot chosen for the outdoor unit. The half-mile around the middle of Crosspost holds about 10 listed buildings and structures. 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 Mid Sussex council, which is normally the planning authority for Crosspost.
Is Crosspost within the area you cover?
Yes, and the size of the place makes no difference to how we work. Send a few details and pictures, and we reply the same working day.
Which accreditations do you hold?
As the law requires for refrigerant work, we are an F-Gas certified company. NICEIC approval, MCS certification for heat pumps and Checkatrade membership sit alongside it.
Which commercial systems do you fit?
We install wall-mounted, cassette, ducted, multi-split and VRF systems. We recommend the type that suits your space.
What warranty do I get?
Warranty is the manufacturer’s own, on its terms. Terms differ by brand, and we set them out on your quote.
Are you TM44 assessors?
The inspection itself must be done by an accredited energy assessor. What we do is prepare the system and carry out the improvements the report suggests.
Do I need to service the system to keep the warranty?
Check the manufacturer’s terms. Some warranty terms require the system to be serviced regularly by a qualified engineer, so it’s worth checking. Keep every service record either way.
Looking after it afterwards
Looking after the system is mostly common sense. A few tips:
- Show staff how to use the controls properly
- Plan replacements before old systems fail
- Plan the air conditioning alongside the fit-out
The warranty on the equipment is the manufacturer’s, on its own terms. We explain the terms for your brand, including any servicing conditions and you will know what they ask for.
Train staff to use the controls sensibly. Units heating and cooling the same space at once is a common problem and correct settings avoid it.
How the visit works
Our engineers bring the tools, gauges and access equipment the job needs. You only need to give us clear access to the units, or their planned positions, and to the fuse board. The visit takes as long as the site and the system need, from a short install to a phased project planned around opening hours. Photos of the existing unit help with repairs and servicing in Crosspost.
- You tell us about the building and what’s needed.
- A site survey confirms the heat load, the layout and the access.
- We set out the options, the price and the programme.
- We install around your hours, phased where necessary.
- The system is commissioned and maintenance can be arranged.
Before we arrive
- Give us access to the outside wall, roof or yard where the outdoor unit sits
- Clear a path to the units and the space around them
- Tell us about access, such as roof hatches, high walls or locked plant areas
Get a fixed-price quote
Photos are the fastest route to a quote: the room or the existing unit, the outside wall or roof where the outdoor unit sits or would go, and the label on any existing unit. Tell us the address and what you need, and many jobs can be priced from that.
Advice
A customer’s words
“Office air con broke down in the July heatwave. Called at 8am, engineer was here by noon and fixed within 2 hours. Brilliant emergency response. They now hold the service contract for the whole building.”
