When comparing air conditioners in the same capacity range (9,000-12,000 BTU), the spec sheet often looks nearly identical: same Inverter technology, same R-32 gas, very similar stated performance. The real differences, though, show up in three specific figures: seasonal cooling efficiency (SEER), seasonal heating efficiency (SCOP), and indoor unit noise. Here’s how four of the most popular brands on the Italian market stack up.
Cooling efficiency (SEER)
In the 12,000 BTU category, LG and Daikin rank near the top for seasonal cooling efficiency, a figure that directly affects summer running costs. This means that, for the same number of hours of use, these two brands tend to cost less on your electricity bill than models with a lower SEER, even at a similar purchase price.
Heating efficiency (SCOP)
If you plan to also use the unit for heating in the shoulder seasons, SCOP is the figure to check. Here Daikin confirms itself among the best in the category, followed by Mitsubishi: both brands have long-standing, specific heat pump expertise, reflected in above-average heating efficiency.
Noise level
On noise, Hisense is a pleasant surprise, ranking first in both the 9,000 and 12,000 BTU categories in independent comparisons among the most popular brands — a notable result for a brand often seen as more budget-friendly than its Japanese and Korean rivals.
Features and tech
On tech features, the four brands take different approaches: Hisense leans on integrated Wi-Fi and cloud with self-cleaning filter functions via freezing and defrosting the internal coil; LG and Daikin generally offer advanced filtration systems and optional or built-in connectivity depending on the model; Mitsubishi focuses mainly on motor quality and reliability rather than extra features.
In summary
There’s no outright winner in this comparison, because the four brands excel in different areas: Hisense for anyone after maximum quiet, LG for the best summer efficiency, Daikin for anyone who’ll also use the unit in winter, Mitsubishi for anyone who wants the sturdiest build quality and isn’t watching the price. Before choosing, figure out which of these factors matters most for your specific situation.
