I live in the Atlanta area and are considering replacing my 20 year old Trane Furnace and AC in the near future.
My current furnace is a single stage and has a single speed blower and I have not had to replace anything on it in 20 years except the igniter. I am planning on only getting an 80% AFUE furnace due to the additional costs associated with venting and draining a higher efficiency furnace as my furnace and water heater are in a basement. Also my Utility bills are not that high.
The concern I have is with the new types of blower motors used in the variable speed furnaces and the reliability of them. I guess my old trane single speed has the Older PSC motor design which appears to be more reliable than the ECM motors I have seen discussed.
I guess if you have a 10 year parts labor warranty then it would be a non-issue however if the older technology blower motors are more reliable I would like to stick with that versus the variable speed blower motors that tend to fail in a shorter period of time.
Does everyone concur with this? Also can you get a 2 stage furnace with an older single speed blower motor (PSC)?
Just trying to narrow down my choice to the most reliable 80% AFUE furnace:
1 Stage versus 2 Stage and whether to have a one speed PSC Blower motor or variable speed blower motor:
Also are there more reliable variable speed motors than others? X13, etc?
Thanks in advance for any discussion on this topic
