What you should know
– The number of zones depend on the square
footage of the space. It is always best and more
comfortable to divide different floor levels
into separate zones.
Electric / Gas – An electric (heat
pump) is not as warm as gas. A combination of
gas and an electric heat pump is best.
Fan – Heat should naturally rise out of
the home. However, when it becomes trapped the
home demands additional cooling from the comfort
system. An attic fan will remove this trapped
heat. This reduces the home’s demand for cooling
and can reduce utility costs (for cooling) by up
Handling Unit – If your system has an
air conditioner, this unit can be a gas furnace
or an oil furnace.
- If your home
comfort system is a “heat pump”
then you have a unit outside very similar to an
air conditioning unit except it is designed to
produce heat during cold weather. If you have a
gas or oil furnace as an air delivery system
inside your home then you have an air
conditioner outside that only runs during the
warmer months for cooling.
thermostat is the control device that
regulates what cycle you are in; heat or cool.
It also regulates the indoor temperature. There
are many different models, including standard
mercury type, digital, and digital programmable.
refrigerant lines are the copper tubing
lines that connect the indoor and outdoor
sections. These pipes allow the refrigerant to
flow from indoor to outdoor.
Refrigerant, in most
interacts chemically inside the entire system.
compressor pumps similarly to the human
heart by pumping and creating a scenario very
similar to your own blood pressure. There is a
high side and a low side and the chemical
reaction created by the produced pressure
actually forces the refrigerant to cool the
central duct system distributes air
throughout the home. This is achieved by using
many different “take offs,” which connect to the
supply air registers. There is also a larger (in
most cases) grill for the “return” air delivery,
which is directed back to the air-handling unit.
The duct system, when installed correctly,
balances the temperature throughout the home,
providing comfort for your family.
- Most homes
use the throw away type of filter
that should be replaced at least once a month.
In any case, these throw away filters are very
inefficient and many homes now have the more
efficient media type filtering device
or electronic filtering devices.
