Buying guide
Six steps to choose an air conditioner or heat pump suited to your home, then order the equipment and its accessories.
01 — Describe your project
List the rooms to equip with their floor area, ceiling height, exposure and insulation. Specify the use: cooling, heating or both. If your home has water-based central heating (radiators, underfloor heating), an air-to-water heat pump can replace the boiler.
02 — Choose the type of system
One room: single-split. Two to five rooms with a single outdoor unit: multi-split. The whole home, discreetly: ducted unit with multi-zone control. Central heating and hot water: air-to-water heat pump. Offices, shops and buildings: commercial ranges and VRF systems.
03 — Estimate the capacity
For cooling, allow about 100 W per m² for a 2.5 m ceiling, then adjust for exposure and insulation. For heating, capacity is determined by a heat loss calculation: ask your installer for one.
04 — Check compatibility
Make sure the indoor and outdoor units are compatible with each other (same range, combinations approved by the manufacturer) and with your electrical supply, single-phase or three-phase. Identify where the outdoor unit will go, the length of the refrigerant lines and how condensate will drain.
05 — Plan the installation accessories
Add what the installation needs to your order: refrigerant lines, trunking, condensate drainage, wall or floor supports, controller or thermostat. Check on each product page what is supplied with the unit.
06 — Have it installed by a professional
Split air conditioners, VRF systems and split heat pumps must be connected and commissioned by a company holding a refrigerant handling certificate (attestation de capacité in France). If supporting documents are required for your order, you are told before purchase.
