FAQs, GENERAL INFORMATION & OPERATING TIPS
What about humidity control?
Geothermal units do an excellent job of removing humidity during cooling. This results in better comfort. However,
during heating (depending on your home and outdoor air temperatures) you may experience the effects of having
too little humidity indoors. This is not the fault of the unit—it does not remove any humidity during heating (unlike a
gas furnace). In the event that your home does not maintain optimum indoor humidity levels of 40-50% relative hu-
midity during the heating season, you may benefit from using a whole house humidifier integrated into your system.
Contact your dealer and refer to page 49 for more information.
Should the duct work be cleaned?
Ducted HVAC systems can be a collection point for a variety of contaminants (mold, fungi, bacteria and dust) that
have the potential to adversely affect your health. In addition to improved indoor air quality and the possible health
benefits of duct cleaning, the EPA has demonstrated that HVAC systems run more efficiently when these contami-
nants are removed from the system. Older homes, or homes with smokers, pets, and people sensitive to allergies
could benefit from duct cleaning. Many HVAC contractors can perform an inspection and duct cleaning using spe-
cialized equipment. Contact your dealer for more information.
Can the air in the home be “sanitized” in any way?
Indoor air quality can be improved using special ultra-violet (UVC) lights placed in the air distribution system. Al-
though these lights do not remove any contaminants (you’ll still need a filter) they will kill (or render sterile) airborne
or surface microorganisms including bacteria, germs, mold spores, and pollens. In addition to the health benefits
of this technology, equipment efficiency can be improved by the fact that the air coil is kept cleaner. Contact your
dealer for more information.
What is ENERGY STAR®?
ENERGY STAR
®
is a program supported by the U.S. Dept. of Energy and the EPA, designed
to help homeowners and businesses protect the environment using superior energy efficient
technologies. Nationwide, the annual savings using ENERGY STAR
®
products is equal to the
amount of energy required to power 20 million homes, and avoid greenhouse gas emissions
equivalent to 18 million cars. This represents billions of dollars in savings.
Energy efficient choices for the home can save you up to one third of your energy bill without sacrificing features,
style or comfort. When considering new household appliances, consider ones that have earned the ENERGY
STAR® rating. They meet strict efficiency guidelines established by the government. In addition to appliances,
whole homes can be constructed with ENERGY STAR® standards built right in. For more information on ENERGY
STAR®, go to www.energystar.gov.
