Overview
- New-generation split ACs use an indoor and outdoor unit connected by a closed refrigerant cycle and inverter technology to deliver both cooling and heating with seasonal COP values up to five.
- Efficient models can consume as little as 100 kWh of electricity per summer season, driving annual power costs down to roughly €30 for cooling and €104–€233 when used daily over four months.
- Germany’s federal BEG programme offers grants for high-quality split installations in low-energy buildings, reducing net upfront costs on systems priced from €449 to €899.
- Top Hantech deals at retailer ACTEC include a 9 000 BTU unit for €449, a U-Fresh 12 000 BTU model with A+++ efficiency and allergen filtration at €698.99, and an 18 000 BTU HPRO offering 5.1 kW cooling for €899.
- Certified installation typically adds €800–€2 000 in fees, and pairing split systems with rooftop photovoltaics lets homeowners cool using surplus solar power rather than drawing from the grid.
