1. Know
Air Conditioners
before choosing it for
your House

2. House with Cross Ventilation
You can Reduce cooling load with a well-insulated
and weatherized home with efficient lighting and
appliances
You can Save up to 30% on operating costs
Look for the Label: Energy Star

3. Choose the Right Size
When you install central air conditioning Size
matters
An oversized air conditioner turns on/off and it uses
more energy, raising your bills

4. Know your AC Capacity

5. How to calculate your house
cooling needs
• Don't hire a contractor who wants to size
your unit based solely on the floor area of your
house
The contractor measures your house, notes the window
area and the direction the house faces, and measures
insulation levels

6. Compare bids from different
Contractors
• Ask your contractor to size the air conditioner based
on the latent cooling load (humidity of the air) as well
as the sensible cooling load (temperature of the air)
for your home

7. • Install for ease of Maintenance
Make sure the inside coil can be reached for
cleaning.
• The coil should be cleaned every two years.

8. Leave plenty of room for free air
flow on all sides
• Place the outside unit on the north or east
side of the house, out of direct sunlight, but
don't add shade for it
• The air conditioner draws a lot of air through
it. So lot of space is needed than for it to be
well shaded.

9. Safety Considerations for Your Air
Conditioner
Weight
Get help when carrying and installing the unit
as it is generally heavy
Noise
Although newer units are much quieter than
older models, be prepared for some additional
noise in the room

10. Always unplug the unit before doing any
maintenance
Installation and Maintenance

11. Keep the filter and coils clean or replace them
as recommended by the manufacturer
Remember filter maintenance alone will
increase your AC's efficiency.
