What is multi-split air conditioning?

Multi-split pairs a single outdoor unit with several indoor units (2 to 5). Each room has independent control for tailored comfort throughout the home.

At Hecker & Frères Énergie (HFE), we size every installation based on floor area, exposure and the number of rooms to be cooled. Wall-mounted units, low-level floor consoles or ceiling cassettes: we tailor the solution to each layout.

As reversible systems, multi-split and air-to-air heat pumps cool in summer and heat in winter with excellent efficiency — an economical alternative to direct electric heating.

Benefits of multi-split

  • Several rooms cooled with a single outdoor unit.
  • Independent control room by room.
  • Wall-mounted, floor console or cassette units as needed.
  • 2-in-1 solution: cooling and supplementary heating.
  • Ideal for flats or multi-storey homes.
  • Economical alternative to 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.

About this installation

As part of this project, we installed a Panasonic TZ42 reversible air conditioning system providing optimal comfort all year round.

The installation includes four indoor units distributed across the rooms of the home to guarantee even temperature distribution. Among them, a low-level floor console was installed to fit the layout perfectly, while a ceiling cassette was fitted for discreet integration and excellent air distribution.

All refrigerant lines, electrical supplies and condensate drains were carefully routed using trunking, ensuring a clean, neat and aesthetic finish while making the installation easy to maintain.

This project gives the customer an efficient and economical solution to cool the home in summer and heat it in winter, while enjoying excellent thermal comfort throughout the house.
