Consider installation costs and requirements when you’re shopping around. Here are some things to remember:
- Most traders offer supply and install packages, and some installation only. Installation must be done by a company’s licensed air conditioner installer, due to the refrigerant gas handling.
- Cool air is heavier than warm air. So, for optimum cooling, the air outlet should be installed as close to the ceiling as possible, with the louvres pointing horizontally or upward. For heating, point the louvres downwards.
- It’s generally better to install an air conditioner on a longer wall of a room, but your installer should recommend the best place for your individual situation.
- The outdoor unit of your split system needs to be installed on a firm base (for example, a concrete slab) or attached to a wall, using sturdy brackets. It should be as close as possible to the indoor air outlet, ideally with about three to five metres of pipes between the two units.
- Shade the outdoor part of your air conditioner from direct sunlight.
- Last but certainly not least, once you’ve got an air conditioner installed, be sure to keep it clean and well-maintained for years of efficient running.
