Key takeaways
- Most aircon installation jobs in Ireland land between €1,500–€22,000 — known locally as air conditioning installer.
- Ireland follows EU F-Gas rules: refrigerant handling requires certification, and electrical connections should be done by a registered electrician (Safe Electric). AC is less common than in hotter markets, so installer availability and pricing vary more by region.

What affects the price
- Job size and scope — bigger or more complex jobs move you up the ranges above.
- Access and condition — hard-to-reach areas, older properties or neglected maintenance add labour time.
- Materials and quality level — where materials are involved, the grade you choose often matters more than labour.
- Urgency — same-day or out-of-hours work usually carries a premium.
- Where you live — large metros in Ireland typically run above the national range; smaller towns below it.

Frequently asked questions
What size air conditioner do I need?
Sizing is by room area, ceiling height, insulation, window area and sun exposure — a good installer does a load calculation, not a guess. An undersized unit runs constantly and never cools; an oversized one short-cycles and wastes energy. Insist on a sizing rationale in the quote.
How long does an aircon install take?
A back-to-back single split is often a half-day job; a multi-split takes one to two days; ducted installs run two to four days depending on the ductwork. Long pipe runs, wall chasing and crane access for outdoor units add time.
How much does it cost to install air conditioning?
A single-zone split unit for one room is the cheapest entry point; a multi-zone system serving several rooms is a mid-range job; a ducted/central system for a whole home is the priciest. The unit's size (in BTU/kW) and the difficulty of the pipe and cable runs drive cost more than the brand.
Who is legally allowed to install air conditioning?
Handling refrigerant is regulated almost everywhere — installers need the relevant certification (see country notes) and often a separate electrical licence for the power supply. Uncertified refrigerant work is both illegal and a common cause of leaks and voided warranties.
What maintenance does air conditioning need after install?
Clean or replace filters regularly, and have the system serviced roughly annually — coil clean, gas-pressure check and drainage clear. Skipping maintenance cuts efficiency, breeds mould in the drain, and shortens compressor life. Ask about a service plan at install.
What does aircon installation cost in Ireland?
A single split runs roughly €1,500-4,000 installed; multi-splits €4,500-11,000; ducted from around €8,000. Because demand is lower than in hot climates, quotes vary widely — get three.
