From enquiry to handover in Sevenoaks
Survey
We measure the space, check the ceiling void, wall construction, glazing and occupancy, and agree where indoor and outdoor units can go. For sites in Sevenoaks we confirm access and parking beforehand.
Design and quote
You get a written specification with unit sizes, positions, pipe routes and a fixed price — plus any planning, landlord or noise points to resolve first.
First fix
Pipework, cabling and condensate runs go in, usually above ceilings or in neat trunking, before the units are hung.
Install and test
Indoor and outdoor units are fitted, the system is pressure tested with nitrogen, evacuated and charged with refrigerant.
Commission and hand over
We set up controls, check air flows and temperatures, show your team how to use it and hand over the F-gas and commissioning paperwork.
Local points to consider
Condensate
Every cooling unit produces water. We route it to a drain by gravity where possible and fit a quiet condensate pump where not.
Access and parking
Town-centre jobs in Sevenoaks often come down to access — loading restrictions, parking for the van and getting equipment onto a roof. We check this at survey and plan deliveries around it.
Landlord consent
Most commercial leases need the landlord's written consent before external units or wall penetrations go in. We can provide drawings and unit data sheets for the request.
Shared buildings
In multi-let buildings, roof space, risers and plant areas are often controlled by a managing agent. We work to their permits and method-statement requirements.

All of them, including TN13. Give us your postcode when you enquire and we will confirm the visit details.
How long does a commercial air conditioning installation take?
A single split system is usually fitted in a day. A small office or shop with three or four units typically takes two to four days, and a VRF system for a whole floor can take several weeks. We confirm the programme in the quote.
Which refrigerant will you use?
In Great Britain, new single split systems holding less than 3 kg of refrigerant cannot use a refrigerant with a global warming potential of 750 or more, so most are now R32. Larger systems may use R32, R454B or R410A depending on the equipment. We state the refrigerant and charge in the quote.
