To
help you better understand the cooling process,
please look over the material below. This is
general information that you will find helpful
when working with a dealer.
Central Air Conditioning
A Residential Split System Central Air Conditioning
system keeps your entire home cool in the warmer
months, while it helps lower indoor humidity
levels.
System elements include a compressor, a fan,
condenser coil, evaporator coil, and a refrigerant.
The unit extracts heat from indoor air and transfers
it outside, leaving the cooled indoor air to
be re-circulated. The efficiency of central
air conditioning systems is shown using SEER
ratios (see below).
Three elements make up a central air conditioning
system with electricity as its power source.
They are:
An
outdoor section (the condensing unit).
A
matching indoor gas or oil furnace with coil,
or air handler.
Ductwork
to transfer the cooled air throughout the
home.
Electric Heat Pumps
A
Residential Split System Heat Pump is a year
'round comfort system. In the summer it draws
heat out of your home to keep it cool, and
in the winter it draws heat from outside air
into your home to keep it warm. Many heat
pump installations have a booster electrical
resistance heater that automatically supplements
heat brought in from the outside. Outside
air always has heat in it - even at very low
outdoor temperatures.
Just the central air conditioning system,
an electric heat pump includes a compressor,
a fan, outdoor coil, indoor coil, and a refrigerant.
The efficiency of Heat Pumps is rated using
SEER (for cooling efficiency) and HSPF (for
heating efficiency).
A Heat Pump uses electricity as its power
source, and requires:
An
outdoor Heat Pump section.
A
matching indoor gas (natural or propane) or
oil furnace with coil, or air handler.
Ductwork
to transfer the heated or cooled air throughout
the home.
Air Cleaners and Other Accessories
Home comfort is more than just heating and
air conditioning. It also depends on regulating
the flow of heat, eliminating drafts, and
improving the quality of the air you breathe.
Electronic and Media Air Filters
Electronic air cleaners can remove up to 95%
of airborne dust, pollen, odors, tobacco,
and cooking particles. Advanced passive media
filters are up to five times better at cleaning
than typical furnace filters. Both are installed
in your home's ductwork, typically adjacent
to a furnace or air handler. Effective filtration
systems can help maintain or improve the operating
efficiency of heating and cooling equipment.
Operating costs savings have been projected
as high as 15% over the life of the system.
SEASONAL TIPS
Getting the most comfort and highest efficiency
from your HVAC system.
Maintenance
Follow
manufacturer's routine maintenance directions.
Have
entire system checked once a year by a qualified
service technician.
What Homeowners Can Do:
Check
Filters
Permanent
- Clean with mild detergent, per manufacturer's
recommendations, every 30 to 60
days.
Replaceable
- Replace every 30 to 60 days.
Windows and Doors
Keep
closed when system is running.
Caulk
and weatherstrip to close air gaps.
Close
drapes and shades over windows facing sun.
Activities
During
cooling season, don't wash/dry clothes during
warmest times of day (late morning and
afternoon).
When
cooking, use exhaust fan only as needed.
Keep
thermostat at desired setting.
