Quick answer
Total cost includes equipment, installation, electricity and care. A flat summer cost means little without operating hours and power input. Calculate using average electrical input, not the advertised cooling capacity.
Calculate electricity costs
Consumption in kWh = average electrical input in kW × operating hours. Cost = kWh × your variable tariff in CHF/kWh. An inverter adjusts its output, so actual average input can differ from its nominal rating.
Example: 0.45 kW × 4 hours × 35 days = 63 kWh. At an assumed CHF 0.32/kWh, this costs CHF 20.16. The 32 centimes are an example tariff, not a Swiss average. ElCom reports a 2026 median of 27.7 centimes/kWh for its standard household using 4,500 kWh annually; your local tariff may differ.
How usage changes the bill
These are scenarios, not typical costs for particular equipment classes. Fixed standing charges are excluded. Improve your estimate by measuring a suitable plug-in appliance with an approved, appropriately rated meter, or using documented system consumption readings.
| Assumption | Consumption | Cost at CHF 0.32/kWh |
|---|---|---|
| 0.45 kW, 4 h, 35 days | 63 kWh | CHF 20.16 |
| 0.8 kW, 5 h, 60 days | 240 kWh | CHF 76.80 |
| 1.2 kW, 8 h, 60 days | 576 kWh | CHF 184.32 |
Separate purchase and installation
An attractive equipment price often excludes window accessories and fitting. Fixed installations may also need drilling, pipework, electrical work, a condensate pump, scaffolding and supporting documents. Ask for VAT and exclusions to be stated explicitly.
Compare complete operational solutions with one another. Also ask about filter costs, servicing scope, call-out charges and spare parts. A low starting price may be misleading when pipe routes are long.
Specific price examples, not market guarantees
As checked on 30 October 2026, ecofort lists the Midea PortaSplit at CHF 1,349. I.ON quotes CHF 3,500–5,500 as an indicative single-split installation price. These are supplier examples, not nationwide ranges. Check availability, accessories, options and the actual project scope separately.

Calculate using your own assumptions
Use average electrical input, not cooling capacity. These values are an example, not a Swiss average.
Estimate excludes fixed standing charges. Actual input and operating time may vary.Frequently asked questions
Does 2.5 kW cooling capacity mean 2.5 kWh of electricity every hour?
Not automatically. Cooling capacity describes heat transfer. Your electricity bill depends on electrical input or measured consumption.
Can I apply the examples to any bedroom?
No. Sun exposure, insulation, temperature settings, efficiency and running time vary. Use the calculation with your own assumptions.
