Air Cleaners and 
Humidifiers
Systems equipped with electronic or 
mechanical air cleaners and/or humidifi-

energy recovery ventilator offers the 
advantage of exhausting stale air from the 
home and allowing fresh air in from the 
outdoors while minimizing heat loss.
Zoning
Your system may also be equipped with a 
zoning system which allows individual 
control over the temperatures of separate 
areas of your home.
