Unlike a furnace it doesn't burn fuel to make heat. It simply uses electricity to move heat from one place to another. In the cooling mode, an air conditioner or heat pump simply capture heat from inside your home and transfer it outside.

In heating, a heat pump actually reverse-cycles and captures heat from outside and moves it inside. This process is more efficient than electric heat as it is much less expensive to transfer existing heat than to actually generate it.

There is usable heat in the air down to about 0 degrees Fahrenheit. It feels cold to us because our skin temperature is 98.6 degrees

A heat pump's heating capacity is rated at 47 degrees ambient (outside) temperature.

As the outside temperature drops the heat pumps capacity drops in a linear fashion relative to the outdoor temperature. Most heat pumps will produce about half of their rated capacity at 12 degrees ambient.

An electric heating element provides supplemental heat to assist the heat pump as it's capacity declines. The heat pump monitors both the outdoor temperature and inside supply air temperature and energizes the assist as needed, automatically.

The brand new 13 SEER packaged unit also boasts a high-performance, high efficiency scroll compressor (2 ton units feature a high-quality reciprocating compressor) that operates in tandem with the high efficiency coil. Scroll details

The coil is constructed of refrigeration-grade copper tubing and aluminum fins in a design that maximizes surface area and heat transfer.

And if that's not enough, Goodman goes one step further and installs a liquid-line filter drier in every package unit they build. This filter drier prevents moisture and debris from entering the compressor and expansion device, helping to preserve the life of the system.

Many manufacturers leave this important step out, but Goodman has always installed filter driers in their products because they can add many years to the life of a unit.

If you are replacing an existing package unit, simply complete the ductwork, gas, and electrical connections and your new system will be up and running, providing dependable year-round comfort for you and your family.

Be sure to comply with your local building code requirements to ensure your new system operates in the safest and most trouble-free manner possible. Qualified personnel must always complete the gas line and electrical connections.

Once in a while, a new technology is developed that gains widespread acceptance through superior function and design; the Copeland Scroll Compressor has gained respect and industry-wide acceptance through time-tested field use and not from laboratory theory.

The Copeland Scroll Compressor has proven itself to be the quietest and most dependable ever created.

Here's why:

The Copeland Scroll technology is based on the concept of compliance.Two scroll members interact to simultaneously achieve high efficiency and durability.

This efficient twisting motion greatly reduces the numbers of parts that can fail while eliminating the inefficient up and down piston motion of ordinary compressors.

This unique and patented approach. achieving both radial and axial compliance - provides important advantages:

• Continuous flank contact, maintained by centrifugal force, minimizes gas leakage and maximizes efficiency.
• Radial compliance allows the scroll members to separate the presence of liquid refrigerant or debris, thereby substantially improving durability and reliability.
• Axial compliance allows the scroll to remain in continuous contact in all normal operating conditions, ensuring minimal leakage without the use of tip seals.
• Both radial and axial compliance allow the scroll members to actually wear in rather than wear out.
