Increasingly, yes for some — particularly for home offices, south-facing bedrooms, and conservatories. Ireland's recent summers have brought 28–32°C heatwaves that older houses don't shed effectively. AC is most useful in homes with single-aspect rooms (no cross-ventilation), top-floor bedrooms, or rooms with extensive glazing. For whole-house cooling, look at modern heat pumps with built-in cooling rather than dedicated AC. For single-room comfort, split AC is the standard solution.

A single-room split install: 4–6 hours on site. The indoor unit is mounted on the wall, the outdoor unit on the wall outside or on the roof, and refrigerant pipework runs between them through a small hole. An electrician connects mains power. Multi-split systems take 1–2 days. Lead time from order to install is typically 3–8 weeks given supply chain on popular units.

A modern 2.5kW inverter AC running cooling for 6 hours daily during an Irish heatwave costs roughly €1.50–€2.50 per day in electricity. Over a 4-week summer with maybe 15 hot days, that's €25–€40 per year. Heating-mode running (using AC as a winter heater) is more expensive — typically as efficient as a heat pump, so 30–50% cheaper than electric resistive heating but more expensive than gas.

Less than you'd think for occasional use. Modern inverter AC is highly efficient — a 2.5kW unit draws around 600W on a typical cooling load, less than a kettle. Using it for the dozen or so hottest evenings each year adds maybe €25–€50 to your annual bill. Continuous summer-long use (always-on bedroom AC) would add €100–€200 per year per unit. Pair with smart controls to schedule and avoid waste.

Yes — annual service keeps it efficient and catches problems early. Service includes filter clean, refrigerant pressure check, drain test, electrical safety check, and software/firmware update on smart units. €100–€180 typically. Most warranties require annual service to remain valid. Skipped service drops cooling output and increases running costs noticeably within 2–3 years.
