Trane or Amana; Single stage vs 2 stage
I have a 2400 sq ft, single story home in DFW, TX area. Over the last 2 yrs, my average electric bill is $160/mo. I have two proposals for replacing my total electric HVAC system with a heat pump. First proposal is a Trane, 5 ton, 15 SEER, with variable speed airhandler. The second proposal is for an Amana, 5 ton, 16 SEER, 2 speed heat pump with variable speed airhandler. The Trane has a 10 yr parts and labor warranty, the Amana has a lifetime replacement on hp, 10 yrs on parts and labor. The cost difference between the two systems is negligible. The Trane proposal is for a XA13 system and the Amana is a ASXC16. My confidence in each company's installers and warranty support is the same. So my dilemma is which one to choose. I have not had experience with either manufacturer and I know what I'm asking is going to be very subjective, depending on who is answering. But I've still got to ask: "Which would be the correct choice?" Is the Amana reliable?
