From enquiry to handover in Hayes

  1. Survey

    We measure the space, check the ceiling void, wall construction, glazing and occupancy, and agree where indoor and outdoor units can go.

  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. In Hayes we agree timings around your opening hours.

  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.

Points to plan for in Hayes

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.

Power

Larger systems need a dedicated supply from the distribution board. We check capacity at survey so there are no surprises on install day.

Working hours

Most Hayes businesses prefer noisy work outside trading hours. Early starts, evenings and weekends can be arranged and are priced up front.

Typical premises in Hayes

  • 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.

Which postcodes do you cover in Hayes?

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.

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.
