How much does it cost to replace air conditioning in Lisburn?
Our guide range in Lisburn is £1,500–£4,095 per indoor unit before VAT; a typical job (replacing a 3–4 unit system, re-using sound pipework) is £5,450–£13,350 plus VAT. The fixed price follows a free survey.
Air conditioning replacement is removing an old system — often one using R22 or R410A refrigerant — and installing new, more efficient equipment, re-using pipework where it is safe and compatible.
Covering Lisburn and nearby
Lisburn supports a mix of high-street retail, professional offices, hospitality and light industry. Belfast is about 11 km away.
That includes premises in BT27 and BT28 and the surrounding districts. Neighbouring towns we cover include Belfast, Castlereagh and Newtownabbey. In Lisburn, 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.

Before you book in Lisburn
Downtime
We schedule the swap to keep the space usable, often over a weekend.
Leased premises
If your Lisburn 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.
R22
Since 1 January 2015, R22 systems cannot be maintained using virgin or recycled R22. If one leaks, the practical fix is usually replacement.
Access and parking
Town-centre jobs in Lisburn 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.
Typical premises in Lisburn
- Schools and education: classroom cooling, ventilation and IT room cooling, installed in the holidays.
- Retail and shops: comfortable shop floors, stockrooms and entrances, even with the door open.

Two rules matter for most businesses in Northern Ireland: EU F-gas rules that apply in Northern Ireland (leak checks from 5 tonnes CO2e) and the periodic energy inspection for more than 12 kW of air conditioning.
