Quick answer
At €0.3142 per kWh (first half of 2026), a typical 3.5 kW (12,000 BTU) split air conditioner (energy class A++), which uses about 0.57 kWh of electricity an hour, costs about €0.18 an hour to run in Italy, or €43 for a month at 8 hours a day. Over a year it comes to about €135 in Rome, from €72 in Turin to €189 in Palermo. A portable unit costs about €0.31 an hour. In U.S. terms the price is about 35.06¢/kWh, 92% more than the U.S. average.

Yearly cost by city
How long the AC runs matters as much as the price of power, and that varies hugely across Italy. This table is for one 3.5 kW (12,000 BTU, about 1 ton) split unit, energy class A++, which uses about 0.57 kWh of electricity for each hour it runs. Hours per year is our estimate of how long it runs at full power in each city's climate, and cost per year is those hours × 0.57 kWh × €0.3142.
| City | Hours the AC runs per year | Cost per year, 3.5 kW split unit | Cost per year, portable unit (same hours) |
|---|---|---|---|
| Palermo | 1,050 | €189 | €330 |
| Bari | 850 | €153 | €267 |
| Naples | 850 | €153 | €267 |
| Rome | 750 | €135 | €236 |
| Florence | 650 | €117 | €204 |
| Bologna | 600 | €108 | €189 |
| Milan | 550 | €99 | €173 |
| Turin | 400 | €72 | €126 |
Cooling hours are our estimate of full-load hours for each city's climate. For comparison, the EU energy label assumes 350 hours for an average European climate. The portable column assumes a typical unit drawing about 1 kW.
Cost by unit size
In Europe, air conditioners are sold by how much cooling they put out, in kW (the BTU size is in brackets). A bigger unit cools a bigger space but uses more electricity. All at energy class A++ (SEER 6.1) and €0.3142/kWh:
| Unit size (cooling output) | Typical use | Cost per hour of running | Cost per month (8 hours a day) | Cost per year in Rome (750 hours) |
|---|---|---|---|---|
| 2.5 kW (9,000 BTU) | bedroom or small room | €0.13 | €31 | €97 |
| 3.5 kW (12,000 BTU) | living room | €0.18 | €43 | €135 |
| 5 kW (18,000 BTU) | large room or open-plan space | €0.26 | €62 | €193 |
| 7 kW (24,000 BTU) | small apartment (multi-split) | €0.36 | €87 | €270 |
| Portable | one room, no installation | €0.31 | €75 | €236 |
What a more efficient unit saves
The energy label shows the unit's seasonal efficiency (SEER) and class: the higher the SEER, the less electricity it needs for the same cooling. Yearly cost of one 3.5 kW (12,000 BTU) unit in Rome (750 hours a year):
| Efficiency (EU SEER) | Energy class | Cost per year | Saved per year vs an old SEER 4.6 unit |
|---|---|---|---|
| 4.6 | B (older unit) | €179 | — |
| 5.1 | A | €162 | €18 |
| 6.1 | A++ (typical new split) | €135 | €44 |
| 7.0 | A++ (mid-range) | €118 | €61 |
| 8.5 | A+++ | €97 | €82 |
| 10.0 | A+++ (top models) | €82 | €97 |
EU SEER is measured in a different way from the U.S. SEER used elsewhere on this site, so the numbers can't be compared directly. Going from A++ (6.1) to A+++ (8.5) saves about €38 a year in Rome. Many split units are heat pumps that also heat in winter, and there the heating rating (SCOP) usually matters more.
What to know about electricity prices in Italy
The price used here is the average household price, all taxes and fixed charges included (first half of 2026).
Since July 2024 most Italian households buy electricity on the free market. Those who didn't pick a supplier were moved to the Servizio a Tutele Graduali, a transitional service that runs until March 31, 2027, while vulnerable customers (for example people over 75) can stay on regulated terms.
Many offers price electricity by time band: F1 is weekdays 8:00–19:00, F2 is weekday early mornings and evenings plus Saturday daytime, and F3 is nights, Sundays and holidays. Weekday afternoon AC falls in F1, usually the dearest band, so a two-band (bi-orario) offer suits homes that cool mostly in the evening and at weekends.
The figure here is Eurostat's average, which spreads fixed charges over every kWh. Northern cities like Milan and Turin have short, humid summers; the south and the islands run AC for much of the year.
Cutting the cost
- Close shutters or blinds on sunny windows before the heat builds.
- Set 25–26°C rather than 21°C. Each degree warmer saves several percent.
- Cool the room you're in, with the door closed, rather than the whole home.
- Clean the indoor unit's filters every few weeks in summer.
- If you're buying, a small split unit costs far less to run than a portable one.

Frequently asked questions
How much does it cost to run air conditioning per hour in Italy?
About €0.18 an hour for a typical 3.5 kW (12,000 BTU) split unit (EU SEER 6.1, energy class A++), which uses about 0.57 kWh of electricity an hour, at €0.3142/kWh. A 2.5 kW (9,000 BTU) bedroom unit costs about €0.13 an hour, and a portable air conditioner about €0.31 an hour.
How much does air conditioning cost per month in Italy?
Running a 3.5 kW split unit 8 hours a day for 30 days uses about 138 kWh, or about €43. A portable unit used the same way costs about €75.
Is a split air conditioner cheaper to run than a portable one?
Yes, by a wide margin. A portable unit draws about 1 kW and cools less well, partly because its exhaust hose pulls warm outside air back into the room. A 3.5 kW split unit at SEER 6.1 draws about 0.57 kW on average while delivering more cooling, so it typically costs about half as much per hour.
How we calculated this
Electricity used (kWh) = cooling capacity (kW) ÷ SEER × hours. Cost = kWh × price. Price: Eurostat, electricity prices for household consumers (nrg_pc_204), 2,500–4,999 kWh a year, all taxes and levies. U.S. dollar figures use €1 = $1.116 (October 14, 2026). Cooling hours are our estimate for each city. To check your own price, divide the energy part of your bill by the kWh used.
