Twelve years later it still is asked. here is a real life situation. I'm vacationing in Florida for a coupel of weeks. My Son-in-law is the maintenance manger for two apartment complexes bot about 3 years old, both have 400 units. One is all Goodman. The other is all Trane.
The Goodman building had tenants call between 8 and 18 times every day for AC problems. The Trane building had no calls. Now there wre a few calls that were tenant stupidity, but most were actual failures.
Enjoy your Goodman, but I'll go with Trane or Carrier. I'm looking at buyina hose here and they use Trane for reliability and lack of customer call backs.
