We just replaced a 16 year old Lennox gas forced-air furnace and AC with a Trane XR95 gas forced air unit. I have a Honeywell thermostat, digital. The furnace seems to cycle a lot in colder weather... the Lennox ran for 20 minutes or so and then was off for at least that long. This one goes for 10 minutes, then off for ten minutes and so forth. Is the correct? This is a 95% efficiency furnace. The Lennox was an old Pulse 21 that Lennox does not make parts for anymore.
