From enquiry to handover in Dorset

  1. 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 Dorset we confirm access and parking beforehand.

  2. 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.

  3. First fix

    Pipework, cabling and condensate runs go in, usually above ceilings or in neat trunking, before the units are hung.

  4. Install and test

    Indoor and outdoor units are fitted, the system is pressure tested with nitrogen, evacuated and charged with refrigerant.

  5. 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.

Things to check in Dorset

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.

Access and parking

Town-centre jobs in Dorset 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.

Condensate

Every cooling unit produces water. We route it to a drain by gravity where possible and fit a quiet condensate pump where not.

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.

Who we work with in Dorset

  • Retail and shops: comfortable shop floors, stockrooms and entrances, even with the door open.

In England, systems holding 5 tonnes CO2 equivalent of refrigerant or more fall under GB F-gas rules, with regular leak checks and records; buildings with more than 12 kW of air conditioning in total also need a periodic energy inspection.

Can you install while we stay open?

Usually, yes. We plan noisy or messy work (ceiling access, core drilling) for quiet periods, early starts or out of hours, and keep work areas screened and clean.

What warranty do I get?

Manufacturer warranties vary by brand and model and usually depend on the system being serviced at the intervals the manufacturer sets. We give you the warranty terms for the equipment we quote.
