ENERGY SAVING TIPS

1.  Relaxing room temperature at night is OK:

During the nighttime hours you 

don't require the same level of conscious cooling or heating. Try using Sleep Mode to
gradually relax room temperature and allow the unit to run less and save energy.

2.  Curtains and shades:

In the summer, you need to block the effects of the sun. 

Close window curtains and shades on the south and west side of your home to help
block solar heat. In winter, the sun is your friend. Open curtains and shades to allow
solar heat into your room.

3.  Close doors:

If you don’t need to heat and cool your whole home, confine the heating

and cooling to one room by closing doors. Limit the space you’re heating and cooling 
to specified capability of the unit.

4.  Service the unit:

Some basic maintenance might be all you need. The outdoor unit

will greatly benefit from a good hosing out, especially in treed areas where seeds and
other debris can stick to coil fins and make the unit work up to 15% harder!

5.  Rearrange the room:

Furniture that obstructs airflow means you could be heating

and cooling the back of a chair or the front of a sofa instead of the actual living space.
Remove or rearrange obstacles blocking airflow.

6.  Try 75 degrees:

75°F is a good point for an air conditioner to run at its optimal 

performance level. Even a 5-degree change in temperature can make your unit use 
up to 40% more energy!

7.  Lighting:

Turning lights off can help reduce your heat. Each light bulb is a tiny heater.

Your air conditioner must waste energy overcoming the heat from your lights to reach
and hold your desired room temperature.

8.  Is anyone home?

If possible, while you're away turn your unit to Auto mode and

make sure windows and drapes are closed. Although room temperature may be less 
than optimal for a few minutes when you come home, the unit will soon have the 
room back to your desired temperature.

9.  Don't forget the fan:

The fan is much like a car. The faster it runs, the more energy it

uses. Sometimes we need the car to go fast, but slow is good enough most of the time.
Try saving money by using the comfortable quiet low fan speed as much as possible.
