Do high efficiency furnaces really pay off ??? From what I have seen in
newer high effiency hvac equipment the cost savings thru higher
efficiency are offset by the higher repair costs.....

You can look on the internet and see many many stories of furnaces that
have to have the igniters replaced yearly or bi yearly....flame sensors
need cleaning...... heat exchangers needing replacement after only a
few years......newer equipment doesnt last like the old stuff
did.....then you have your hvac companies who spend as much time on
parts replacement or new equipment sales training for their technicians
than on real trouble shooting and maintenance training.

I still see old williamson, carrier, lennox, janitrol, bard
furnaces.....all brands that were installed 30-35 years ago still
kicking along every winter...good tight heat exchangers...they might
require service every few years...usually a thermocouple...if even
that....seems withn the newer equipment its something every
season....inducer motor bad, flame sensor dirty, bad board......

Today the only way you can expect your furnace or ac to operate right
is to have a maintenance agreement with an hvac contractor...this
offsets savings even more...and then you might be unfortunate enough to
get saddled with a maintenance outfit that requires its employees to
sell so many parts a month...which is quite common....

So....really....Is a new high effiecincy furnace or ac system really
gonna save anyone money.....
