Air Conditioning FAQs
A single split system cooling one room costs €1,500 to €3,000 fully installed. A multi-split system serving 2 to 4 rooms costs €4,000 to €8,000. Portable units cost €300 to €600 with no installation needed, but are significantly noisier and less efficient. Running costs for a split system are approximately €0.15 to €0.30 per hour at current electricity rates for a standard-sized room. Annual professional servicing costs €80 to €150.
In most cases no. A domestic air conditioning split system does not require planning permission. However, if the outdoor unit is exceptionally large, produces significant noise, or is positioned prominently on a front elevation, some local authorities may raise concerns. In apartments or managed housing estates, you typically need management company approval before installing an outdoor unit. Always consider the noise impact on your neighbours when choosing the unit's position.
Indoor units operate at 19 to 30 decibels, which is quieter than a whisper and virtually inaudible in a furnished room. Outdoor units are louder at 40 to 55 decibels, producing a constant low hum similar to a fridge. Noise levels vary by brand and model, and premium brands tend to be quieter. Careful placement of the outdoor unit away from bedroom windows and neighbours' boundaries minimises any noise impact.
Yes. Most modern split systems are reversible, functioning as air-to-air heat pumps that provide efficient heating at a coefficient of performance (COP) of 3 to 4. This means they produce 3 to 4 units of heat for every 1 unit of electricity consumed, making them highly efficient. In Ireland's mild winters, a split system can serve as a very effective primary or supplementary heating source for the room it serves, often more cheaply than running a gas or oil boiler.
If you have a well-insulated room with large south or west-facing windows that overheats in summer, or if you work from home in a room that becomes uncomfortable on warm days, air conditioning makes a significant quality-of-life difference. The reversible heating function adds year-round value. With Irish summers trending warmer and new homes being built to increasingly airtight standards, residential demand for air conditioning has grown steadily over the past five years.
A single split system installation takes 4 to 8 hours, typically completed in one working day. The main time is spent routing refrigerant pipework and electrical connections between the indoor and outdoor units, which may involve drilling through external walls and running pipe along the exterior. Multi-split systems with multiple indoor units take 1 to 2 full days. The system is operational immediately after installation and commissioning.
