When choosing a heating and air
conditioning system for your home, there are a variety of equipment
options available depending upon your home and location, but your
needs and expectations are the most important factors when deciding
what type of system will keep you and your family the most
comfortable in the coming years.
(Of course, if you're thinking about replacing your system or trying
to decide on a system for a new house, our
Comfort Advisors are available to
meet with you, discuss your needs and expectations and design a
system specifically for you.)
A Heat Pump is a heating and air
conditioning unit
that regulates temperature by moving
air.
Heat Pumps are split systems. That
is, they are made up of an outdoor (condensing) unit and an indoor
unit (coil). Like a refrigerator, heat pumps use electricity to move
heat from a cool space into a warm one (or vice versa).
For example,
during the heating season, heat pumps move heat from the outdoors
into your house. Because they move heat rather than generate
heat, heat pumps can provide up to 4 times the amount of energy they
consume.
For homes without ducts, air-source
heat pumps are also available
in a ductless version called a
mini-split heat pump.
Like standard air-source heat pumps,
mini splits have two main components: an outdoor
compressor/condenser, and an indoor air-handling unit. Ductless,
mini-split-system heat pumps (mini splits) make good add ons to
houses with "non-ducted" heating systems, such as hydronic (hot
water heat), radiant panels, and space heaters (wood, kerosene,
propane). They can also be a good choice for room additions, where
extending or installing distribution ductwork is not feasible. The
main advantages of mini splits are their small size and flexibility
for zoning or heating and cooling individual rooms.
The Seasonal Energy Efficiency Ratio
(SEER) rates a heat pump's efficiency like Miles Per Gallon (MPG)
measures the fuel efficiency of your car:
 |
The higher the SEER,
the more efficient your equipment is.
|
 |
As of January 2006,
13 is the new minimum standard efficiency.
|
 |
In general, higher
SEER equipment costs more than lower SEER equipment.
However, over the life span of the system, energy
savings will help offset the initial cost.

High-efficiency heat
pumps also dehumidify better than standard central
air conditioners, resulting in less energy usage and
more cooling comfort in summer months.
