HOME COMFORT SYSTEM - PACKAGE UNIT
HOW IT WORKS
Operation depends on configuration, but packaged units typically heat and cool your home the same way their stand-alone counterparts do.
The duct work with a single cabinet packaged unit is slightly different than its atand-alone counterpart. The duct work is attached to the system rather than connecting to various components in your home.
The heating component of a packaged gas-electric system is a gas furnace. The heating portion of the system uses natural gas or propane to combust inside the heat exchanger, creating heat. As cool air from the interior spaces is pulled in through the return ducting, the blower motor then blows the air over and through the hot heat exchanger, heating the air. The warm air is then circulated throughout the home through the ductwork.
Space efficiency - Unlike split-system units, all components of a complete heating and cooling system are contained in one location, making packaged units ideal situations in which indoor space is at a premium.
COOL YOUR HOME FOR LESS
Seasonal Energy Efficiency Ratio (SEER) is the rate by which all air conditioning and heat pump energy efficiently is measured. In the world of cooling, the higher the SEER, the better the efficiency and the lower your energy bills.
HEAT YOUR HOME FOR LESS
Annual Fuel Utilization Efficiency (AFUE) measures the amount of heat actually delivered to your house compared to the amount of fuel supplied to the furnace. For example, a furnace that has an 80% AFUE rating converts 80% of the fuel to heat - the other 20% is vented out to your roof as wasted money. The higher the AFUE rating, the better the energy efficiency and the less money you waste.
Most systems 15 years or older are rated around 65% AFUE. Upgrading to a Einstein modulating furnace rated at 97% AFUE can save around $1,694 a year on energy costs. And of course, as the cost of natural gas rises, you'll save even more.
