From enquiry to handover in Northamptonshire
Survey
We measure the space, check the ceiling void, wall construction, glazing and occupancy, and agree where indoor and outdoor units can go.
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.
First fix
Pipework, cabling and condensate runs go in, usually above ceilings or in neat trunking, before the units are hung. In Northamptonshire we agree timings around your opening hours.
Install and test
Indoor and outdoor units are fitted, the system is pressure tested with nitrogen, evacuated and charged with refrigerant.
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.
Local points to consider
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.
Leased premises
If your Northamptonshire premises are leased, the landlord's written consent is usually needed for external units, wall penetrations and roof access. We provide drawings and data sheets for the request.
Condensate
Every cooling unit produces water. We route it to a drain by gravity where possible and fit a quiet condensate pump where not.
Conservation areas
Historic streets and listed buildings in and around Northamptonshire are more likely to need planning permission for outdoor units on visible elevations. We check with the local planning authority before work is booked.
Types of premises we cover in Northamptonshire
- 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.
