What is single-split air conditioning?

Single-split (mono-split) is the most common reversible air conditioning system for a single room. It pairs one outdoor unit with one wall-mounted, floor console or ceiling cassette indoor unit, depending on the layout.

At Hecker & Frères Énergie (HFE), we size every installation based on the area to be cooled, exposure and insulation. A technical survey is carried out before every quote to ensure optimal comfort and controlled energy use.

As a reversible system, single-split cools in summer and can heat in winter with excellent energy efficiency — an economical alternative to direct electric heating.

Benefits of single-split

  • 2-in-1 solution: cooling and supplementary heating.
  • Quick installation, often completed in one day.
  • Ideal for a room from 15 to 45 m².
  • Precise temperature control.
  • Discreet, compact wall-mounted unit.
  • Lower consumption than direct electric heating.
Accessory

Decoclim outdoor unit cover

The Decoclim outdoor unit cover is an aesthetic solution designed to conceal outdoor air conditioning units and heat pumps. Made from powder-coated aluminium, it withstands weather, UV rays and corrosion while keeping a clean, modern look.

Its louvered design allows optimal airflow, ensuring the installation runs properly without affecting performance. Robust and durable, it also protects the outdoor unit from minor impacts and improves how the equipment blends into a garden, terrace or façade.
