What do rating numbers mean?
The U.S. government requires an efficiency rating of all air
conditioning and heating equipment. The rating reflects the percentage
of energy used efficiently, with a high rating indicating
high-efficiency. The next two topics address this issue in greater
detail.

What is a SEER?
There are special names for the efficiency ratings of various types of
equipment. Air conditioning equipment is rated by the Seasonal Energy
Efficiency Rating, or SEER. The higher the SEER rating, the more
efficient the unit.

Should outdoor units
be covered in winter?
No. Ruud heat pumps operate year-round and should never be covered.
Similarly, air conditioners that operate seasonally are built to
withstand an outdoor environment and should not be covered.

Should a thermostat
be set to "auto" or "on"?
Preferably auto. That way, the fan operates only when the temperature
requires it. This is the most used and the most efficient setting.
However, there are advantages to using the "on" setting. Air is
constantly filtered through the unit's air filter, and the constantly
circulating air results in an even temperature throughout the house.

Can
shrubs or flowers be planted around an outdoor unit?
Yes. However, we recommend that plants be no closer than 18 inches to
the unit. This allows for plenty of room for air circulation in and out
of the unit. Without this room for air circulation, the unit could
overheat, resulting in a premature need for service.

If an outdoor unit needs replacing, should the indoor unit be replaced
too?
Yes. Ruud air conditioning and heating units are designed to operate as
a complete, matched system. The efficiency rating is based on the entire
system. Replacing the entire system ensures the system will be reliable
and efficient.

How do I know
what size unit our house needs?
Your service man will consider many factors before making a
recommendation. Factors like … size of the house, climate, the number
and type of windows installed, insulation, and even the number of people
living in the house.

What is the difference between a split system and a package unit?
A split system uses indoor and outdoor components to provide a complete
home comfort system. A package unit or self-contained unit requires no
external coils, air handlers, or heating units.
