South Mundham questions
Is South Mundham within the area you cover?
Yes. South Mundham is within the area we cover across London and the South East. A few photos and the postcode are enough to get things started.
Is planning permission needed for air conditioning in South Mundham?
That depends on the building and where the outdoor unit goes. Around 5 listed entries sit within 0.5 miles of central South Mundham. 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 Arun council, which is usually the planning authority for South Mundham.
Whose job is it to check the system for leaks?
The F-gas rules share it between the equipment’s operator and the engineers who work on it. The interval depends on the refrigerant charge, measured in tonnes of CO2 equivalent: at least every 12 months from 5 tCO2e, and every 6 months from 50 tCO2e.
Can you look after our air conditioning after it’s installed?
Yes, and we tailor the schedule to the system and how hard it works. There’s also a 24/7 emergency line for breakdowns.
What types of commercial air conditioning do you install?
Wall-mounted, cassette, ducted, multi-split and VRF or VRV systems. The right one depends on the building and how it’s used.
Are you F-Gas certified?
F-Gas certified, NICEIC approved and MCS certified for heat pumps, plus Checkatrade membership. Engineers who handle refrigerant hold their own F-gas qualifications as well.
When will I hear back?
You will hear from us the same working day. For a breakdown that cannot wait, call our 24/7 emergency line.
Commercial air conditioning in South Mundham
Air conditioning systems with an effective rated output over 12 kW must have a TM44 inspection at least every 5 years. The inspection is carried out by an accredited energy assessor. We don’t carry out the inspection itself, but we prepare the system and do the work it recommends. Typical jobs include planning ahead for the HFC phase-down and F-gas leak checks and records that are overdue, across wall-mounted split systems, ceiling cassettes and multi-split systems.
For a business near South Mundham, outdoor units typically have room at the back of the building, out of sight and away from neighbours.
The records are your system’s health record: a dated account of the work and the readings we took. It makes the next visit quicker and any warranty question simpler, so keep it safe.

After we have gone
Here’s the after-treatment advice, short and simple:
- Keep plant areas tidy
- Do not wait for small faults to become breakdowns
- Diary TM44 inspections in advance
Handover includes a walk-through of the controls so staff can set it up properly. Getting the settings right helps the system perform.
Keep filters clean and plant areas clear. Blocked filters and obstructed outdoor units make the system work harder.
Why it’s worth doing now in South Mundham
R410A systems are still legal to repair, though supply of the gas is tightening. It’s better to replace on your terms than after a breakdown. Getting the date in early helps for a place like South Mundham.
Every job is different, so each one gets its own fixed-price quote. The system, the access, the pipe routes and the parts involved all make a difference.

What we are called out for in South Mundham
When a space is refitted or its use changes, the old layout may no longer work. New partitions, more staff or different equipment change the heat load and the system needs to match the new layout.
Keep an eye out for any of the following:
- F-gas leak checks and records that are overdue
- Comms rooms without enough cooling
- Buildings that cannot close for the work
If you look after a school such as North Mundham Primary School, classroom, office and IT room cooling is usually installed in the holidays.
What your quote should include
- Whether the manufacturer’s warranty depends on regular servicing
- Whether the electrical work is done by a registered contractor, such as NICEIC approved
- Whether anyone has checked the property or the system first
