An air conditioner that also heats: how does that work?

A modern air conditioner does not just cool, it also heats efficiently. We explain how and when that is a smart move.

A modern split-system air conditioner works on the same principle as a heat pump: it moves heat. In the summer, it extracts heat from your home (cooling), while in the shoulder seasons, it brings heat inside (heating), often more efficiently than your central heating boiler.

In short
  • A split-system air conditioner cools and heats (heat pump principle)
  • Efficient heating in the shoulder seasons
  • STEK-certified installation
  • Quiet and with convenient Wi-Fi control

How heating with an air conditioner works

The outdoor unit extracts heat from the outside air and the indoor unit blows it into your room as warm air. On mild days, this is an efficient way of heating, because the air conditioner provides more heat than it consumes in electricity.

When is it a smart choice?

An air conditioner with a heating function is ideal for rooms you want to heat or cool quickly, such as a home office, bedroom, or attic. For heating your entire home, a heat pump is usually the better choice.

Professional and compliant with standards

An air conditioner contains refrigerant; therefore, installation must be STEK-certified performed by a certified professional. Our own technicians install the unit neatly, quietly, and safely, with the pipes tidily concealed.

Frequently asked questions

Does an air conditioner also heat during frost?

Modern units heat well below freezing, although efficiency decreases during severe frost. It is an efficient addition for the shoulder seasons.

Is an air conditioner efficient?

For cooling and heating in the shoulder seasons, a modern air conditioner is efficient: it provides more heat/cooling than the electricity it consumes. Combine it with solar panels for maximum benefit.
