Wall-mounted air conditioning in Lisburn
A single wall-mounted unit is often all a bedroom or sunny living room in Lisburn needs. Damp Northern Ireland winters make a heat pump's dehumidifying mode useful well beyond the summer.
In a semi or terrace in Lisburn, the indoor unit often goes on a back bedroom wall with the outdoor unit on a bracket below. Our County Antrim coverage takes in Lisburn, about 7 miles from Belfast. That includes the BT27 and BT28 postcode districts.
Prices in Lisburn
In Northern Ireland, our guide range for wall-mounted air conditioning is £1,045–£2,695 per room, including VAT. Labour rates in Northern Ireland keep this slightly under the national middle. Longer or hidden pipe runs, high-level brackets and electrical upgrades are the usual reasons a quote lands at the top of the range. As an example, the Popular option (quieter mid-range unit with Wi-Fi control and better seasonal efficiency for a living room) would typically be £1,445–£1,995 here.

Guide prices show VAT at 20%. HMRC treats most fixed air conditioners and air-to-air heat pumps installed in homes as energy-saving materials, zero-rated until 31 March 2027 when we supply and fit them. If your installation qualifies, your quote shows 0% VAT and a lower price. Servicing, repairs, cleaning and controls are charged at 20%.
Planning and permissions
Planning rules for outdoor units in Northern Ireland differ from Great Britain's, so we check your property with you and the council where needed.
