Commercial Air Conditioning
Air conditioning installation, servicing and repair for offices, retail units, restaurants, warehouses and schools across London, Kent, Essex, Sussex and the South East. F-Gas qualified engineers, direct contact, no call centres.
Commercial Sectors We Cover
From single offices to multi-unit retail, we design and install systems suited to how your business actually operates.
Offices
Consistent year-round comfort for staff, with systems that heat as efficiently as they cool, and zoned control for shared workspaces.
Retail Units
Discreet systems that keep customers comfortable without disrupting shop layout, fitted around trading hours to avoid disruption.
Restaurants & Kitchens
Cooling and ventilation designed to work alongside extraction systems, keeping kitchens safe and dining areas comfortable.
Schools & Colleges
Reliable climate control for classrooms and halls, installed to minimise disruption to the school day and term-time schedules.
Warehouses & Industrial
Larger-scale systems for spaces with high ceilings and open floor plans, including ducted and VRF options where needed.
Landlords & Managed Properties
A single point of contact for portfolio maintenance across multiple units, with scheduled servicing to keep tenants comfortable.
Commercial System Options
The right system depends on your building, not a one-size-fits-all package. Here's what we typically install for commercial premises.
Single & Multi-Split Systems
One or more indoor units connected to a shared outdoor condenser. Cost-effective for individual offices, single retail units or smaller premises.
Ducted Systems
Concealed ductwork distributes air through discreet ceiling grilles, keeping the finished look clean for offices and retail spaces where appearance matters.
VRF / VRV Systems
Variable Refrigerant Flow systems for larger commercial buildings, offering zoned control across many rooms from a smaller number of outdoor units.
Fresh Air & Extraction
Ventilation systems that work alongside cooling to maintain air quality, particularly important in kitchens, workshops and high-occupancy spaces.
Commercial Air Conditioning Costs
Every commercial job is different, so these are guide figures only. Your fixed price is confirmed after a free, in-person site survey.
| Space size | Typical system | Guide price range |
|---|---|---|
| Small office or unit (up to 500 sq ft) | Single or multi-split | £2,000 – £5,000 |
| Medium space (500–2,000 sq ft) | Multi-split or ducted | £5,000 – £15,000 |
| Large space (2,000+ sq ft) | Ducted or VRF/VRV | £15,000+ |
Final cost depends on space size, system type, building access, existing electrical capacity and any structural work required. A site survey is the only reliable way to get an accurate figure, and ours are free with no obligation.
Servicing & Maintenance
Commercial systems are built to last 15-20 years with regular maintenance, but efficiency can drop by around 5% a year without it. An unplanned breakdown in a working business isn't just inconvenient, it can be a genuine disruption to trade.
We offer scheduled maintenance plans so your system stays reliable and cost-effective, whether we installed it originally or not. If it wasn't installed by us, your manufacturer warranty may vary, but we can still service and maintain it.
