Hvac for 14 years. I have goodman at my house, 4 years no problems what so ever. I'd take goodman over trane and carrier any day and that's what we mainly sell/service.
I replaced a Trane with a Goodman (15 seer matched set / AC only). My unit was original from 1992, new one saved us probably $70 a month all summer long, runs about the same amount of time but quieter and cooler.
