Brazos doesn't fulfill it's part on the warranty that came at a high price and of course the unit I bought from them is now absolete and parts are no longer availabe. Hum? How convenient for Brazos. I paid close to $10,000 for the Heat Pump with a 10 year All parts and labor warranty in 2004. Never did it ever cover any parts or labor. Oh yes, and I also paid for the yearly maintenance agreement separately. I'm done with Brazos. Thank you.
