ABA series Furnaces are available in sizes from 40,000 to 140,000 BTUH input and can be installed in up-flow, down-flow, or horizontal applications.  All models are only 31 5/8" tall, which makes it much easier to add the extra tall cooling coils associated with 13 SEER (and higher) installations.  The ABA also features a smart self diagnosing system that monitors all operational functions.  All furnaces are thoroughly run tested for 34 different operations before they ever leave the factory.  Each component carries a 5 year parts warranty.  The patented tubular heat exchanger, made of aluminized steel with a non-welded construction, promises years of trouble free operation, and is backed by a 20 year warranty.
