FAQ, 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 humidity
during the heating season, you may benefit from using a whole house humidifier integrated into your system. Contact
your dealer for more information.
Should the ductwork 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 contaminants 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 specialized 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. Although
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
