Can plants be planted around or near the outdoor unit?

Plants can be planted near the air conditioners outdoor unit, although you should make sure there is plenty of room around the outdoor unit. Air must be able to flow freely in and out of it. If it can’t, the outdoor unit can overheat and sustain major damage. It is also a good idea to keep all plants, shrubs and limbs trimmed back because they can lower the performance of the air conditioner and cause damage if leaves or twigs are sucked into the outdoor unit.

How can I lower energy consumption whilst operating my air conditioner?

If you close curtains, blinds, windows and doors, you can significantly help your air conditioner cool a room more effectively and use less energy. Air conditioners with inverters and “auto” settings are generally more energy efficient as they automatically adapt and maintain the desired temperature you require.
