Goodman – Furnaces

Goodman has become one of the largest manufacturers of residential and light commercial air conditioning, heating, and indoor air quality products and systems by focusing on just one thing—building the most reliable and refreshingly affordable indoor comfort products in the market. The complete line of Goodman® brand products are built on the principles of founder Harold Goodman, a former air conditioning contractor:

  • Provide industry leading product warranties
  • Offer greater reliability and longer-lasting performance than competing products
  • Designed equipment for quick, trouble-free installations
  • Make reliable cooling and heating as affordable as possible

Building their products to Harold’s standards, and protecting those products with some of the best limited warranties in the industry, has helped to make the Goodman brand widely recognized as a leading brand in the residential and light commercial heating, ventilation and air conditioning industry today.

For over three decades, the Goodman® brand has concentrated on something more important than simple brand-recognition consumer advertising. They have focused on the design, engineering, and manufacturing of dependable equipment.  Goodman remains focused on providing high-quality products at an affordable price, and protecting them with what we believe to be some of the best warranties in the industry. This clear focus has led to Goodman’s being a leading unit manufacturer of residential and light commercial heating and air conditioning products and systems in North America.
