Commercial air conditioning for homes and businesses in Watersfield
Buildings whose air conditioning totals more than 12 kW need a TM44 inspection at least every 5 years. The inspection is carried out by an accredited energy assessor. We do not carry out the inspection itself, but we prepare the system and do the work it recommends. The work covers server and comms room cooling, ducted systems and wall-mounted split systems, and the jobs we see most are server rooms running too warm and commercial systems near the end of their life.
Around Watersfield, there’s normally space for outdoor plant away from the road, out of sight and away from neighbours.
Some warranty terms depend on the system being serviced regularly by a qualified engineer. Where yours does, a regular service with us keeps that side in order and each visit is recorded.

Watersfield: your questions answered
Will air conditioning in Watersfield need planning permission?
There’s no single answer: the building and the outdoor unit position decide it. Central Watersfield sits inside the Watersfield Conservation Area. An air-to-air system used for heating as well as cooling can be permitted development on a house if it meets the conditions, but a cooling-only unit isn’t covered, listed buildings need consent and conservation areas restrict outdoor units facing a road. Where needed, we check with the planning department at Chichester council, typically the authority for Watersfield.
Will you come out to Watersfield?
Yes, smaller places are covered as well as towns. Send a few details and pictures, and we reply the same working day.
Do you install in the evenings or at weekends?
We can. Work can be scheduled around your hours and phase it where necessary.
Do you have a 24/7 line?
Yes, day and night. When you call, tell us the make, what’s happening and any error code, and we will advise on what to do next.
How often is a TM44 inspection needed?
Over 12 kW, a TM44 inspection is needed at least every 5 years. The rules are set out on GOV.UK and we’ll help with the system side.
What types of commercial air conditioning do you install?
Wall-mounted, cassette, ducted, multi-split and VRF or VRV systems. We recommend the type that suits your space.
Can I fit air conditioning or a heat pump myself?
The refrigerant side has to be done by a qualified engineer working for an F-Gas certified company. That is a legal requirement, and it also matters for the manufacturer’s warranty. We are happy to quote for the full job, supply to commissioning.

How it works
On the day, we arrive at the time agreed with you and run through the plan before anything else. Dust sheets go down over floors and anything close to the work, and the electrics are made safe before any panel comes off. The work itself takes a few days for a small shop or office, longer for VRF across several floors. For a place like Watersfield, the timing is set with you and the travel is our side of the planning.
- It starts with a survey on site, looking at the space, the people in it and the equipment.
- You get a fixed-price quote with the equipment, the layout and the programme set out.
- Installation is scheduled to fit the business, with out-of-hours and phased work where needed.
- We fit the units, run and test the pipework, connect the condensate and wire in the controls.
- Commissioning, F-gas records and a handover of the controls finish the job.
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
- Clear access to the fuse board

When a space is refitted or its use changes, the old layout may no longer work. More people, new walls or extra equipment alter what the system has to cope with, and the system has to match.
It’s time to call us if you’re dealing with:
- Staff complaining about the temperature
- Fit-outs and refurbishments that need new air conditioning
- TM44 recommendations that need acting on
Clinics, dental practices and pharmacies around Arundel and District Hospital (about 5.4 miles south) normally want quiet indoor units with filters that are simple to keep clean.
