DEFINITIONS<\/p>\n
The following definitions are oriented to situations typical in Laguna Woods Village.<\/p>\n
21<\/p>\n
HVAC: Heating, ventilation and air conditioning system.<\/p>\n
2.2<\/p>\n
FORCED-AIR CENTRAL SPLIT<\/p>\n
SYSTEM: A ducted system that<\/p>\n
provides both heating (heat pump)<\/p>\n
and cooling. The system consists of<\/p>\n
\u00ab@ n<\/p>\n
an outdoor unit (condenser) and an<\/p>\n
indoor unit (air handler), located in<\/p>\n
Fumi<\/p>\n
><\/p>\n
the attic or a closet. The ductwork<\/p>\n
Air Handi<\/p>\n
for this type of system is typically<\/p>\n
located in the attic space. Air supply<\/p>\n
registers are located in each room<\/p>\n
\u00a2<\/p>\n
with one return air grill centrally<\/p>\n
located.<\/p>\n
