Does Goodmans still exist?

Yes, Goodman still exists and is a very active and growing HVAC brand in North America, including both Goodman Manufacturing for HVAC and Goodmans as a retail chain in other contexts, but for HVAC it definitely still exists. Goodman Manufacturing, founded in 1982 by Harold Goodman in Houston, Texas, is headquartered in Waller, Texas, at the large Daikin Texas Technology Park, and is owned by Daikin Industries of Japan since 2012, which is the world's largest HVAC manufacturer. Goodman makes residential furnaces, air conditioners, heat pumps, and air handlers sold through HVAC distribution across the United States and Canada, offering affordable, value-priced equipment with good warranties of 10 years parts and limited lifetime heat exchanger when registered. Goodman has expanded significantly under Daikin ownership with new factories and increased market share, particularly in the budget and mid-range segments competing with Lennox, Carrier, Trane, and Rheem. The brand Goodman is widely available through authorized dealers and is one of the top selling HVAC brands in North America by units sold due to its affordability. So yes, Goodman still exists and is thriving as a major HVAC brand owned by Daikin, not defunct.
