been away for a while but 2 weeks ago i replaced my 30 year old 40-60% eff (per the only info i could find on it) with a new 2 stage 95% eff furnace with ecm blower. i also replaced the lux thermastate that allowed me to adjust the swing with a nest learning thermostat.
well its been very cold the last few days down into the single digits at night and upper 20s low 30s during the day. its hard to tell how long its actually run but i know it has only kicked into the high stage once (on its own) but i did force it before just to make sure it worked
