Our central AC unit is on it's last leg...it appears to be original to the house or pretty darn close (33 years). It makes a horrible shuttering noise when it shuts off and actually stopped working on Wednesday (a wire had become disconnected).
Anyway, long story short, it is going to have to be replaced, along with the coils (the furnace was replaced when we purchased the home last November). The first technician we had out to give us a price said he would get back to us with 3 options, two would be American Standard and one would be a Rheem. Those sound fine to me as I know the brands and their reputations. The second technician said he would quote me on a Ducane....which I have never heard of. I'm doing some research on-line to compare the brands but thought I would ask here as well.
Question #1: Is the Ducane brand as good as/better than the American Standard or Rheem?
Question #2: Is there a good website that you know of for comparing the units? We will be purchasing a 4-ton 13 seer unit.
Thanks in advance for your thoughts/opinions!
