Air conditioning
How much does air conditioning cost to install in Dublin?
Single rooms to whole homes, with the running costs to match.
Short answer
A single wall mounted unit for one room typically costs €1,500 to €3,000 supplied and fitted. Covering the main rooms of a house with a multi split system runs from about €3,500 to €11,000. Cooling only A/C gets no SEAI grant, and running costs in an Irish summer are low.
