How we work in Hayes
Survey
We size the unit to the room and agree indoor and outdoor positions and the pipe route.
Mount the units
Indoor unit on a mounting plate, outdoor unit on brackets or a frame with anti-vibration mounts.
Pipe and wire
Pipework, interconnecting cable and condensate are run and made off neatly. We keep work areas in Hayes screened and tidy at the end of each day.
Test and commission
Pressure test, evacuation, any extra refrigerant charge, then commissioning and handover.
Points to plan for in Hayes
One outdoor unit, many rooms
Multi-splits save wall space but share a single compressor. For server rooms or critical spaces we recommend dedicated systems.
Working hours
Most Hayes businesses prefer noisy work outside trading hours. Early starts, evenings and weekends can be arranged and are priced up front.
Outdoor unit position
Outdoor units need air flow and access, and should be away from neighbours' windows to keep noise down.
Access and parking
Town-centre jobs in Hayes 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.
Who we work with in Hayes
- Salons and spas: comfortable salons and treatment rooms despite dryers, lamps and steam.
- Healthcare and dental: clean, quiet cooling for surgeries, clinics, dental practices and care settings.
- Pubs and bars: cooling for busy bars, function rooms and cellars, sited with neighbours in mind.
- Gyms and leisure: high-capacity cooling and fresh air for gym floors, studios and changing rooms.
Compliance in England: refrigerant work falls under GB F-gas rules, and buildings with more than 12 kW of air conditioning in total need a periodic energy inspection (often called TM44).

Which postcodes do you cover in Hayes?
All of them, including BR2, UB3 and UB8. Give us your postcode when you enquire and we will confirm the visit details.
Can a split system heat in winter?
Yes. Modern split systems are heat pumps and can heat efficiently down to well below freezing.
Does a small split need F-gas leak checks?
It depends on the refrigerant charge and type. Many small R32 splits fall below the 5 tonnes CO2 equivalent threshold for mandatory leak checks, but they still need installing and servicing by F-gas certified engineers.
