Thanks every one for the info. Yes, old furnace is working fine but
too noisy and we are little cold always even themostat is set to 72.
May need to rethink before start calling out HVAC contractor.

We just got a new Thermo Pride with staged blower and it is quieter than
old Lennox furnace. Lennox was a POS and we did not find until
afterwards that they made cheap grades such as we got ~16 years ago.

Wife was not as satisfied with temperature but I doubt thermometers on
thermostats are that accurate. She became happy when I cranked up new
one a couple of degrees
