A split air conditioning system has an indoor unit and an outdoor unit joined by refrigerant pipework.
Merseyside and surrounding areas
We cover all of Merseyside, including Liverpool, Birkenhead, St Helens, Southport and Wallasey. We quote for premises right across Merseyside, including rural and edge-of-town sites.
Postcode districts we cover include CH25, CH44, L2, L13, L24, L35, L74 and WN5. In Merseyside, outdoor unit positions are often the deciding factor: a rear flat roof or yard is usually straightforward, while a front elevation may need landlord or planning consent first.
What we do
- Wall-mounted, floor-standing or under-ceiling indoor units
- Outdoor unit on wall brackets, a flat roof frame or ground mounts
- Pipework in neat trunking or concealed routes
- Condensate drainage
- Commissioning, remote or wired controls and F-gas records

How it works in Merseyside
Survey
We size the unit to the room and agree indoor and outdoor positions and the pipe route. For sites in Merseyside we confirm access and parking beforehand.
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.
Test and commission
Pressure test, evacuation, any extra refrigerant charge, then commissioning and handover.
Points to plan for in Merseyside
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.
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.
Refrigerant rules
Since 1 January 2025, new single split systems holding under 3 kg of refrigerant in Great Britain cannot use refrigerant with a GWP of 750 or more — in practice, R32 or lower.
Conservation areas
Historic streets and listed buildings in and around Merseyside are more likely to need planning permission for outdoor units on visible elevations. We check with the local planning authority before work is booked.
Who we work with in Merseyside
- Gyms and leisure: high-capacity cooling and fresh air for gym floors, studios and changing rooms.
- Warehouses and industrial: cooling for offices, mezzanines, control rooms and temperature-sensitive areas.
- Pubs and bars: cooling for busy bars, function rooms and cellars, sited with neighbours in mind.
- Healthcare and dental: clean, quiet cooling for surgeries, clinics, dental practices and care settings.
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).
Your questions answered
How much does a split air conditioning system cost in Merseyside?
Guide prices in Merseyside run from about £1,395 to £2,895 per system, plus VAT. A typical job (two-room multi-split) costs £3,395–£5,850 plus VAT. We fix the price in writing after a free survey.
Do you also cover Cheshire, Greater Manchester and Lancashire?
Yes. Alongside Merseyside, we also cover Cheshire, Greater Manchester and Lancashire. Each has its own page with local guide prices.
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.
