Mini-Splits & SEER
Ductless, mini split-system air-conditioners (mini splits) have numerous potential applications in residential, commercial, and institutional buildings. Ductless mini splits are highly recommended on bonus rooms above garages, computers rooms, additions to a home or office, and other unique set ups where duct will be difficult to install.
Like central systems, mini splits have two main components: an outdoor compressor/condenser, and an indoor air-handling unit. A conduit, which houses the power cable, refrigerant tubing, suction tubing, and a condensate drain, links the outdoor and indoor units. The advantages of mini splits are that they are small and are easier to install than a ducted split system.
WHAT IS SEER? It's an acronym for:
S = Seasonal
E = Energy
E = Efficiency
R = Ratio
SEER is an efficiency ratio in units of BTU's per watt-hour that attempts to address the question: how much do I need to pay my electric utility to cool my house? Well, not really. A SEER rating can't predict your utility bill any more than it can predict the weather, but it does provide a consistent means to compare the efficiencies of various residential air conditioning systems.
