A variable speed motor is different from a standard motor in that it features a high efficiency Electronically Commutated Motor (ECM) by General Electric.

This feature is important because full air delivery is only needed a small portion of the time. During lower demand times this motor reduces its speed providing up to 4 times better humidity control, better air distribution throughout your home, and greatly reduced operating costs.

Better air distribution will provide a marked improvement in those areas of your home where air delivery has been a problem such as the rooms farthest from the blower.

Another important feature of a variable speed Goodman air handler is the reduction of what is referred to as "cold blow", or the cold blast of air upon heating startup.

"Cold blow" results from cold air that develops in the duct system while the heat is in an off-cycle. When the heater fan cycles on, the cold air is moved very quickly into your home resulting in an uncomfortable draft.

The Goodman variable speed air handler virtually eliminates cold blow with a "soft start," or a gradual increase in fan speed over the initial 3 to 4 minutes of the on-cycle.

This cold air is combined with preheated air from the air handler blower and is delivered at a slower velocity until it reaches full operating temperature.

The result? Improved heating comfort and a dramatic reduction of the uncomfortable drafts associated with non-variable speed air handlers.

The Air Conditioning and Refrigeration Institute (ARI) sets the heating ventilation and air conditioning industry's standards for performance and efficiency.

When you use the Goodman ARUF air handlers, you are getting ARI-certified performance, as well as quality, reliability, and comfort.

Standard Goodman air handler quality features include:

• Fully insulated cabinet for quiet operation
• An adjustable multi-speed motor
• Copper tube and aluminum fin coils
• Transformer and blower time delay for maximum efficiency

Goodman uses only high quality, long-lasting rifled copper tubing in their coil construction to withstand the rigors of typical use and to provide maximum heat transfer.

This durable tubing is mechanically bonded to enhanced rippled-edged and louvered fins, providing even heat transfer that's efficient and economical.

Then, to ensure consistent performance, every coil is tested three times to detect leaks. And not just the obvious kind.

Goodman tests for the smallest possible leaks, so small they may only surrender one ounce of refrigerant in ten years. It's this commitment to quality performance that seperates the Goodman ARUF series air handler from the competition.

The Goodman ARUF series air handler is not only among the most dependable made, but can significantly improve the air quality in your home.

Goodman has created a specially-designed drain pan that provides for more complete condensation removal, preventing the build-up of mold and mildew within the system.

And, when you add one of our whole-house air cleaners to your system, you will experience a reduction in dust, pollen and other allergens throughout your entire home resulting in a cleaner, healthier, more comfortable home.

This air handler also includes a supplemental heating element up to 15KW for increased heating capacity. (When purchased as part of an optional electric heat system) Flexible installation

The Goodman air handler is versatile and can be installed as an upflow (ductwork above the air handler), downflow (ductwork under the air handler), and horizontally (air handler in an attic, crawlspace, or basement).

If you are capable, you can do most of the installation yourself and then set up a service call for a professional to come and open the refrigeration system and check the charge.

Any qualified air conditioning technician can easily install this system in your home or office. It will normally require about 5-8 hours to replace an existing, similar type system.
