You may find your Toshiba air conditioning unit needs resetting if it starts to malfunction or isn’t responding to any input via your control panel or remote control.

Cleaning your air conditioner shouldn’t take longer than a few minutes every fortnight. To start, simply check the instructions in your manual. If you have a new Toshiba Air single split system product, feel free to use the instructions below for the best way to clean your air conditioner.

Doing this regularly helps make sure that your filters are working at their optimum level to provide you with cleaner, healthier air in your home.

Dust may build up on the exterior of your air conditioner, including on the sides of its louvres. To remove this, don’t use spray and wipes or other chemicals – simply wipe it off with a damp cloth whenever you notice dust building up.
Your outdoor unit needs to be unobstructed so that air can flow in and out of it freely. Check your unit regularly and remove any rocks, leaves or other debris that might have built up around it. You may need to do this more regularly during autumn if there are trees near your outdoor unit.
Cleaning your air conditioner may not be top of your list of to-dos, but if you spend a few minutes doing it every fortnight, you could save hundreds of dollars, improve the air quality in your home and reduce your power bill and improve the functioning of your unit.
