Advanced Reciprocating
Compressor—Type of compressor
that uses a more efficient process for compressing
refrigerant for better cooling efficiency.
AFUE—Annual
Fuel Utilization Efficiency. Indicated as
a percentage, your furnace’s AFUE tells
you how much energy is being converted to
heat. For example, an AFUE of 90 means that
90% of the fuel is being used to warm your
home, while the other 10% escapes as exhaust
with the combustion gases.
BTU—British
Thermal Unit. Used for both heating and cooling,
BTU is a measure of the heat given off when
fuel is combusted. Or for cooling, it’s
a measure of heat extracted from your home.
One BTU is equal to the heat given off by
a wooden kitchen match.
Capacity—The
ability of a heating or cooling system to
heat or cool a given amount of space. For
heating, this is usually expressed in BTUs.
For cooling, it is usually given in tons.
Compressor—Part
of a split-system heat pump or air conditioner’s
outdoor unit that controls the pressure applied
to the refrigerant, necessary for taking in
heat to warm your home or getting rid of heat
to keep your home cool.
Condenser Coil—Part
of the outdoor portion of a split-system air
conditioner or heat pump. By converting refrigerant
that is in a gas form back to a liquid, the
coil sends heat carried by the refrigerant
to the outside.
Damper—A
type of "valve" used in duct work
that opens or closes to control airflow. Used
in zoning to control the amount of warm or
cool air entering certain areas of your home.
Downflow—A
type of furnace that takes cool air from the
top and blows warm air to the bottom—common
where your furnace must be located in a second-floor
closet or utility area.
Electronic Air Cleaner
(EAC)—An electronic device
that filters out large particles and contaminants
in indoor air. It then electronically pulls
out tiny particles that have been magnetized,
such as viruses and bacteria, drawing them
to a collector plate.
Load Estimate—A
series of studies performed to determine the
heating or cooling requirements of your home.
An energy load analysis uses information such
as the square footage of your home, window
or door areas, insulation quality and local
climate to determine the heating and cooling
capacity needed by your furnace, heat pump
or air conditioner. When referring to heating,
this is often known as a Heat Loss Analysis,
since a home’s heating requirements
are determined by the amount of heat lost
through the roof, entry ways and walls.
Evaporator Coil—Part
of a split-system air conditioner or heat
pump located indoors. The evaporator coil
cools and dehumidifies the air by converting
liquid refrigerant into a gas, which absorbs
the heat from the air. The warmed refrigerant
is then carried through a tube to the outdoor
unit (condenser coil).
Fan Coil—An
indoor component of a heat pump system, used
in place of a furnace, to provide additional
heating on cold days when the heat pump does
not provide adequate heating.
HVAC—Term
used for Heating, Ventilation, and Air Conditioning
HSPF—The
Heating Seasonal Performance Factor is a measure
of the heating efficiency of a heat pump.
The higher the HSPF number, the more efficiently
the heat pump heats your home.
Horizontal Flow—A
type of furnace, installed on its "side,"
that draws in air from one side, heats it
and sends the warm air out the other side.
Most often used for installations in attics
or crawl spaces.
Humidifier—A
piece of equipment that adds water vapor to
heated air as it moves out of the furnace.
This adds necessary moisture to protect your
furnishings and reduce static electricity.
Matched System—A
heating and cooling system comprised of products
that have been certified to perform at promised
comfort and efficiency levels when used together,
and used according to design and engineering
specifications.
Operating Cost—The
day-to-day cost of running your home comfort
equipment, based on energy use.
Payback Analysis—Overall
measure of the efficiency and value of your
home comfort system. By combining your purchase
price and ongoing operating costs, a payback
analysis determines the number of years required
before monthly energy savings offset the purchase
price.
Perfect Heat™—The
Perfect Heat gas furnaces use a two-stage
valve and patented control algorithm allowing
the furnace to more closely meet the heating
needs of the home. A Perfect Heat heat pump
controls the airflow across the indoor coil
and controls auxiliary heater banks to deliver
warmer, more comfortable air to the home.
In both cases the end result is even, consistent
heating.
Perfect Humidity™—Perfect
Humidity will remove an amazing amount of
moisture from indoor air to help eliminate
that warm, sticky, uncomfortable feeling you
get in high humidity. Add a humidifier and
the system provides Perfect Humidity in heating.
Puron™ Refrigerant—Puron
is an environmentally sound refrigerant designed
to protect the earth's ozone layer. Federal
law requires all manufacturers phase out ozone
depleting refrigerants in the next few years.
Puron is approved by the US Environmental
Protection Agency as a replacement from Freon
22*.
Reclaiming—Returning
used refrigerant to the manufacturer for disposal
or reuse.
Reciprocating Compressor—A
type of compressor used in air conditioners
that compresses refrigerant by using a type
of "piston" action.
Recycling—Removing,
cleaning and reusing refrigerant.
SEER—The
Seasonal Energy Efficiency Ratio is a measure
of the cooling efficiency of your air conditioner
or heat pump. The higher the SEER number,
the more efficient the system is at converting
electricity into cooling power.
Scroll Compressor—A
specially designed compressor that works in
a circular motion vs. an up and down piston
action.
Setback Thermostat—A
state-of-the-art electronic thermostat with
a built-in memory that can be programmed for
different temperature settings at different
times of the day.
Split System—Refers
to an air conditioner or heat pump that has
components in two locations. Usually, one
part of the system is located inside (evaporator
coil) and the other is located outside your
home (condenser coil).
Thermidistat—The
Thermidistat Control monitors temperatures
both inside and outside, as well as indoor
humidity and adjusts system operation to maintain
the temperature and humidity levels set by
the homeowner.
Thermostat—Unit
that monitors and controls your HVAC system
products.
Ton—A
unit of measure for cooling capacity. One
ton = 12,000 BTUs per hour.
Total Home Comfort
System—The ultimate solution
to providing you with consistent, customized
home comfort, despite the ever-changing weather.
Upflow—A
type of furnace that draws cool air from the
bottom and blows the warmed air out the top
into the duct work. This type of furnace is
usually installed in a basement or an out-of-the-way
closet.
Ventilator—A
ventilator captures heating or cooling energy
from stale indoor air and transfers it to
fresh incoming air.
Zoning—A
way to increase your home comfort and energy
efficiency by controlling when and where heating
and cooling occurs in a home. Programmable
thermostats are used to control operating
times of the equipment. Dampers are used to
direct air flow to certain parts or "zones"
of the home.
