SEER
or seasonal energy efficiency ratio provides information
about HVAC efficiency. In addition to adequate cooling
capacity, a unit should be efficient. A more efficient
unit will cost less to operate. In fact, many of the
new energy efficient air conditioning units have operating
costs that are half those of older, less efficient
models.
SEER
indicates how much cooling is provided per watt of
electricity on a seasonal basis. The higher a unit's
SEER, the higher its efficiency. Using SEER, the consumer
can easily compare the efficiency of two units. For
example, a unit with a SEER of 10 will be twice as
efficient as one with a rating of 5, and should cost
approximately half as much to operate. Manufacturers
are required by law to publish energy efficiency ratings
and estimated annual operating costs of their residential
air-conditioning systems. |
