Hello;

Will be replacing a gas, forced hot air heating furnace in a typical
split level home, here in the Northeast.

Am trying to learn more about the basics, prior to starting calling
in contractors for quotes.

I remember at one time the Pulse Type of furnace was quite popular.
I have read about over the years some good things about them, and a slew of
real horror stories.

Are they still made ?

Pros and cons for this type ?

Noise level still "bad" ?

As far as the regular gas furnaces go, Carrier and Am. Standard still the
yardsticks to go by ?

Thanks,
B,
