How a job in County Londonderry works
Survey
We size the unit to the room and agree indoor and outdoor positions and the pipe route. For sites in County Londonderry 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.
Local points to consider
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 County Londonderry 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.
Pipe routes
Shorter, simpler pipe routes are cheaper and more reliable. We plan routes before quoting.
Conservation areas
Historic streets and listed buildings in and around County Londonderry are more likely to need planning permission for outdoor units on visible elevations. We check with the council's planning service before work is booked.

Common questions from businesses in County Londonderry
How much does a split air conditioning system cost in County Londonderry?
Guide prices in County Londonderry run from about £1,350 to £2,695 per system, plus VAT. A typical job (two-room multi-split) costs £3,150–£5,450 plus VAT. We fix the price in writing after a free survey.
Do you also cover County Tyrone, County Antrim and County Armagh?
Yes. Alongside County Londonderry, we also cover County Tyrone, County Antrim and County Armagh. Each has its own page with local guide prices.
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.
Can a split system heat in winter?
Yes. Modern split systems are heat pumps and can heat efficiently down to well below freezing.
