Residential HVAC Term Duct board
used in residential construction is a
foil backed dense fiberglass product.
It is normally one inch thick. The duct
board is cut and formed to create a
chase for supply air or return air. As
the duct is put together the joints are
taped with a foil back tape in order to
form an air tight duct. The duct board
supply duct forms the main supply
duct from which either flex or metal
smaller supply ducts are attached.

Residential HVAC Term Combustion Air is the air used to
ignite a gas furnace. As a safety factor, a gas furnace needs a
separate source of air for combustion. The combustion air is
provided by a metal duct that is installed in the furnace closet and
extends through the ceiling into the attic to furnish outside air.

Residential HVAC Term Zoning refers to the process of
dividing a house into zones for cooling and heating purposes.
This type of system can use control dampers in the duct to
control air flow to the individual zones. A thermostat is installed in
each zone. When a zone requires air, the unit will come on and
the damper will open for that zone. The excess air will be diverted
back through the return air duct.

Residential HVAC Term Air Chase
refers to the duct that is used to carry
either supply air or return air to and
from the air handler.This can be
fiberglass duct board, insulated metal
duct, or large flex duct.

Residential HVAC Term Air Flow expresses the amount air
that flows through an air duct per minute. The air flow is
measured and is expressed in cubic feet per minute (CFM).

is the amount of heat it takes to raise
or lower one pound of water one
degree Fahrenheit.

Residential HVAC Term Attic Ventilator refers to a power
vent install on the roof or in the gable end of a house to remove
hot air from the attic. These ventilators are thermostat controls
and only run when the temperature exceeds the setting.

Mechanical Term Seer stands for
Seasonal Energy Efficiency Rating.
Most cities and counties now require a
minimum of a 10 SEER rating. The
higher the rating the more efficient the
cooling unit will operate.
