While I don't agree with Home Guy on everything, I do agree that
in many cases the extra cost of models with an ECM blower aren't
worth it.

I'm guessing that it's increasingly high targets for energy efficiency
(combustion and electrical) set by gov't regulations is the reason why
we're seeing the use of ECM blower motors in consumer HVAC equipment,
just as we see the same when it comes to saftey equipment (air bags, ABS
brakes, CAFE and emissions standards) in cars. *Probably the same reason
for electronic ignition vs standing pilot as well.

I can't believe that we'd see widespread use of ECM motors under true
free-market-driven conditions (ie - with no gov't efficiency mandates or
constraints).

A lot of us don't live where they have 9 months of winter sports, and
humidity control is a huge issue. Where I am, we run A/C from March 1st
until November 1st with average summer temps of 90F with 75% to 85% RH
you can *DO* what you want, you can be as ignorant as you want....thats your
problem.

I'd say it's ignorant to assume everyone that's looking at a new HVAC
system
lives in the same climate that you do. I'm in coastal NJ and the
existing 26 year
old system handles the humidity just fine. If it's hot enough to be
running frequently,
no humidity problem. If it;s one of those few days where it's not hot
enough to be
running and it's getting humid inside, I lower the thermostat one
degree and in 30-45
minutes, you can feel the humidity has decreased and it's
comfortable. And that's
with an inefficient system with a single speed blower.



I do this for a living, and I *KNOW* first hand what the benefits of the new
systems are, and how much my customers utility bills have dropped, as well
as their comfort level increasing.

My utility bills are gonna drop too when I swap out that 26 year old
system and
go to a high efficiency system with a PSC blower.



You can *TRY* to re-engineer a new furnace by taking out the electronics,
ECM motor, and electronic ignition... Just remember that as soon as you
screw with it, you have voided the warranty, as well as the UL ratings and
if you burn your house down, your insurance company will deny the claim.

Maybe you should get a job in the engineering department with the equipment
manufacturers.- Hide quoted text -


That part I agree with. But there is no need to take out an ECM
motor. You just
buy a high efficiency system that doesn't have one in it.
