- Comms rooms without enough cooling
- New tenancies needing cooling and heating
Questions from Cootham
Will you come out to Cootham?
We do. Villages and hamlets get the same service as the bigger towns. We’re based in East Grinstead and plan each visit so the job can be finished in one trip where possible.
Do I need planning permission for air conditioning in Cootham?
That depends on the building and where the outdoor unit goes. Around 8 listed entries sit within 0.5 miles of central Cootham. 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 necessary, we check with the local planning authority (for Cootham, normally Horsham council).
How much time does a commercial air con install need?
The work takes a matter of days for a modest fit-out, with larger buildings phased floor by floor or zone by zone. We confirm the timing after the survey, so phone us on 07833 053749 or use the quote form to arrange one.
Do you offer maintenance contracts?
Yes. Send details of the systems and how they’re used and we’ll propose a schedule and quote for it. That can include the leak checks the F-gas rules require for larger systems.
Who has to arrange F-Gas leak checks?
The F-gas rules share it between the equipment’s operator and the engineers who work on it. How often depends on the size of the refrigerant charge in tonnes of CO2 equivalent: at least yearly for 5 to under 50 tCO2e, and every 6 months for 50 to under 500 tCO2e.
Why does F-Gas certification matter?
For refrigerant work, both the engineer and the company need the right F-gas credentials. Ask to see proof before you book anyone and we will gladly show you ours.
Can I do the refrigerant work myself?
The refrigerant side has to be done by a qualified engineer working for an F-Gas certified company. That’s the law, not just our preference, and manufacturers expect it for their warranty too. We’re happy to quote for the full job, supply to commissioning.
Commercial air conditioning in Cootham, done properly
Air conditioning systems with an effective rated output over 12 kW must have a TM44 inspection at least every 5 years. An accredited energy assessor carries it out; we’re not assessors, but we prepare systems for inspection and act on what the report finds. If the problem is R410A systems getting dearer to top up and buildings that can’t close for the work, we can sort it out.
Around Cootham, there’s normally space for outdoor plant away from the road.
If a fault appears while the equipment is under the manufacturer’s warranty, tell us the make, model and installation date. We’ll tell you how the manufacturer’s warranty is likely to apply before any chargeable work goes ahead.

What else we do in Cootham
Business air conditioning in Cootham
The FSA’s food hygiene register shows about 12 cafés, restaurants and staff canteens in and around Cootham, up to about a mile and a half out. Many of those sites need air conditioning that is sized for long hours and maintained on a schedule.
Schools such as Storrington Primary School typically have the work done in the holidays, when classrooms are empty.
Cootham is about 7 miles north-west of Worthing, in West Sussex. Whatever kind of property you have in Cootham, our engineers can help with commercial air conditioning. We reply to enquiries the same working day, and there’s a 24/7 emergency line. We cover 371 places across West Sussex, from busy centres to quieter spots. For properties nearby, see our Worthing page, about 7 miles away.
Not far from Cootham, a recent job of ours was on School Hill, Storrington (RH20), about 1 mile east: installing two LG wall-mounted units in the waiting room and the main consulting room.
Jobs in RH20 are looked at, quoted and booked the same way as anywhere else. If you need commercial air conditioning at a property on Warren Croft, Pulborough Road and The Crescent or a nearby road, our engineers can take on the work. Neighbouring places we cover include Storrington (1 mile east), Wiggonholt (2 miles north-west), Sullington (2 miles south-east), West Chiltington Common (2 miles north) and Abingworth (2 miles north-east). Larger places within reach include Horsham (12 miles north-east), Worthing (7 miles south-east), Bognor Regis (13 miles south-west) and Chichester (15 miles west).
What’s near Cootham
In Cootham, that means homes and buildings near Rydon Community College, Parham Park and The Crown Inn. The nearest railway station is Pulborough station, about 3.3 miles north-west of the centre. Other landmarks nearby include The Storrington And District Museum (1 mile east) and Amberley Castle (3.2 miles west). Not far away are Chanctonbury Hill and Amberley Wildbrooks RSPB Reserve.
When something else is needed
We will always give you a straight diagnosis, so here’s what commercial air conditioning will not do:
- Carrying out the TM44 inspection itself, which needs an accredited energy assessor
- Major builder’s work such as new openings in structural walls
- Getting landlord or building owner approval
Not sure which it is? You can phone 07833 053749, or email if that’s easier and we’ll tell you honestly before you book.
What the work covers
- Multi-split systems
- VRF systems
- Server and comms room cooling
- Ceiling cassettes
- Ducted systems
- Wall-mounted split systems
Common problems we fix in Cootham
Older systems running on R410A face rising costs for top-ups as the GB HFC phase-down tightens supply. Repairs on existing R410A systems remain legal though it’s worth bearing in mind when planning ahead.
Most people get in touch after spotting one of these:
- New tenancies needing cooling and heating
- Work raised by a TM44 inspection
- F-gas leak checks and records that are overdue
Commercial systems over 12 kW need a TM44 inspection at least every five years.
Comparing quotes
- Whether anyone has checked the property or the system first
- Whether the price is fixed or an estimate
- Whether you get F-Gas records where refrigerant is involved
Before you call an engineer
Before you call us about a fault, a few checks can save a visit: check the mode, the set temperature, the remote’s batteries and the breaker. If a breaker trips again after you reset it, leave it off and phone 07833 053749 or use the quote form.
Good habits make our visits easier, not unnecessary. Clean filters and a clear outdoor unit help the system run as it should, but the refrigerant circuit, the electrics and the parts you cannot see still need an engineer at the interval the manufacturer recommends.
How it works
We keep the work area tidy as we go, with sheets down and mess cleared as we go. Any holes, fixings or cable routes are agreed with you before we drill. On site, it takes a matter of days for a modest fit-out, with larger buildings phased floor by floor or zone by zone. We plan the trip to Cootham around you.
- An engineer walks the building with you to understand its layout, its users and its heat sources.
- You get a fixed-price quote with the equipment, the layout and the programme set out.
- Dates are set with you so trading, teaching or treatment carries on, using evenings, weekends or phases where it helps.
- We fit the units, run and test the pipework, connect the condensate and wire in the controls.
- Finally it’s commissioned and handed over, with the refrigerant records and manuals for your files.
How to prepare
- Mention any managing agent or landlord rules we need to follow
- Unlock any gate, garage or side passage we need
- Make sure someone can let us in at the agreed time

A customer’s words
“Excellent service from start to finish. Two wall-mounted units installed in our home. Clean, tidy work: they protected all the floors and left no mess. The systems work brilliantly. Would highly recommend.”
